Camaro Indy 500 Pace
Car Driven by Racing
Legend Roger Penske
A unique version of the new 2017 Camaro
SS 50th Anniversary Edition leads the 100th
running of the Indianapolis 500 this year,
driven by motorsports legend Roger Penske,
who is marking 50 years as a race team
owner.
It’s the ninth time Camaro has served as the
pace car and the 27th time for Chevrolet,
dating back to 1948. For 2016, Chevrolet
drivers will be looking to build on last year’s
success, when the top four finishers were
Chevy-powered, led by race-winner and
Team Penske driver Juan Pablo Montoya.
It was his second Indy 500 victory and the
16th for Team Penske.
No other racing team has recorded more
wins at the Brickyard than Team Penske,
starting with driver Mark Donohue’s victory
in 1972. They established their relationship
six years earlier, when Penske transitioned
from driver to team owner. They found
success in SCCA’s Trans-Am Series, with an
early Camaro Z/28 racecar, winning three of
12 races in 1967 and 10 of 13 in 1968.

New MDI 2 Offers Next-Generation Communication Interface
As automotive technology continues to advance at a more
rapid pace than ever, ACDelco service technicians have a new
tool at their disposal with the introduction of the GM MDI
2 interface. The next-generation interface allows them to
diagnose and repair onboard automotive electronic systems in
current GM vehicles, as well as future model years.
Multiple Diagnostic Interface 2 (MDI 2), is a communications
device that manages the transfer of data between a GM
vehicle’s Electronic Control Unit (ECU) network with a personal
computer. It improves upon the original MDI introduced almost
10 years ago and offers faster programming speed, the most
up-to-date functionality, increased processing power and
security.
Some features of the new MDI 2 interface include:
• Wireless Connection – Point to Point wireless
communication doesn’t require an access point or IT
support, but uses a simple plug-and-play configuration.
There is also upgraded wireless protocol support.
• High Speed USB 2.0 Connection – Features improved
protection from ground offset failures and better
USB performance, plus reinforced USB connector and
connector housing. The device is also powered through a
USB or DLC connection so no AC adaptor is required.
• Operation During Engine Crank – Super-Caps provide
improved stability during engine crank so there are no
batteries to replace.
• Extended Temperature Range – Industrial components
extend operating temperature range and there’s an
automatic power-down if over temperature is detected.
• Enclosure Design – An improved closure design protects
the tool from exposure to fluids and drops.
• Vehicle Communication Protocol Coverage – New Vehicle
Communications protocols include those for newer
vehicles with faster data busses. They are SAE J2534 and
ISO-22900 compliant.
• DLC Cable – Includes a two-meter DLC cable with twisted
pair wire for newer vehicles.
• New Hardware Expansion Capabilities – Two host USB
expansion ports for future peripherals, an SD memory card
slot for future software applications and programmable
function buttons for future software features come with
the interface.
16ACDELCO_Newsletter_vol3_v1.indd 3
MDI 2 can still be used
with a Wireless Access
Point, or with the new
Point-to-Point wireless
communication and new
vehicle communications
protocols, such as CAN
FD and Ethernet to
support future electrical
architecture changes.
When using the Point-toPoint system, technicians
will use a new Point
to Point dongle that
allows wireless access
directly from the MDI 2
to a computer. Users can
configure a PC to access
TIS using the existing
Wireless Access Point
and connect to the MDI
2 using the dongle. This
allows the vehicle to be
outside the service garage
without interrupting the PC to MDI 2 connection.
Although other manufacturers offer similar interface tools,
MDI 2 is the only one that is fully supported for every GM
vehicle from 1996 forward. A user guide is available at https://
service.gm.com/userguides/index.pdf
Service centers can continue to use the original MDI until nextgeneration vehicles are released. Support for the original MDI
system will continue to be provided under a two-year warranty.
To order the MDI 2, call 1-800-GMTOOLS (Prompt 1, then
Prompt 2) or visit https:// gmtoolsandequipment.com

R-1234yf Refrigerant Rollout Coming to More GM Models
A number of 2017 Chevrolet, Buick, GMC and Cadillac models
will join the current Cadillac XTS and Chevrolet Spark EV in
using the new air conditioning refrigerant R-1234yf. The XTS
was the first U.S. vehicle to use R-1234yf refrigerant in 2013.
R-1234yf is an environmentally friendly alternative to R-134a
refrigerant, which is a greenhouse gas that has been cited as
contributing to climate change. R-1234yf has a 99.7 percent
lower Global Warming Potential (GWP) than R-134a. It is the
industry accepted solution for a low GWP refrigerant.
The following 2017 models are currently targeted to receive
R-1234yf in the North American market: Chevrolet Camaro,
Cruze, Malibu, Colorado, Silverado, Tahoe and Suburban; GMC
Acadia, Canyon, Sierra and Yukon models; Cadillac ATS, CTS
and XT5; and Buick Cascada and LaCrosse. There will be more
vehicles added for the 2018 model year.
The U.S. Environmental Protection Agency’s (EPA) motor
vehicle greenhouse gas regulations require improvements
in overall fuel economy and the use of R-1234yf will play
a considerable role in helping GM vehicles achieve these
targets under the new regulations. The new refrigerant has
been tested and studied extensively by many organizations,
including the Society of Automotive Engineers (SAE)
International, the U.S. EPA, global regulatory and scientific
organizations, as well as every major automotive manufacturer.
All of these groups agree that R-1234yf is a safe and
environmentally friendly alternative to R-134a.
The refrigerant compound is HFO (hydrofluoroolefin) 1234
(1 - double bond, 2 - hydrogens, 3 - carbons, 4 - fluorines) yf
(position of the fluoro atoms).
Differences in Refrigerants
R-1234yf does not require significant changes to the design
of automotive air conditioning systems. It has thermodynamic
properties similar to R-134a, so system diagnosis is similar to
R-134a systems. It also can be handled much the same way as
R-134a, although it does require dedicated service equipment.
(Refer to the appropriate Service Information for the latest
diagnostic and repair procedures.)
While R-1234yf is very similar to R-134a, there are some
important differences. R-1234yf is considered a mildly
flammable gas and should not be serviced near any open flame
or significant source of energy (for example, welding). Like all
automotive refrigerants, it is illegal to release R-1234yf into
the atmosphere. In the case of an unintentional release, the
immediate area should be ventilated; taking additional care to
ventilate pits or low areas as the refrigerant is heavier than air
and can collect in these areas.
Special Tools
New dedicated tools and equipment are required by U.S.
EPA regulations to service vehicles equipped with R-1234yf.
Existing R-134a equipment cannot service R-1234yf because of
fitting differences, refrigerant mixing and safety requirements.
SAE J2843-compliant Recovery/Recycle/Recharge machines
must feature integrated refrigerant identifiers or a USB port
for connection with a hand-held identifier.
SAE J3030 dual-refrigerant R/R/R machines for both R-1234yf
and R-134a have also been introduced recently.
Genuine GM Parts Door Hinges and Hardware Available
ACDelco recently released a number of Genuine GM Parts door hinges, door hinge
detent rollers, door hinge pins and tailgate hinges covering vehicles from 1982-2016.

The New Chevrolet Volt Takes Charge
The 2016 Chevrolet Volt offers an electric range of up to 53
miles (83 kilometers) — a nearly 40 percent increase over the
first-generation model. The all-new Voltec propulsion system
has been redesigned to be even more efficient, which helps
deliver improved fuel economy as well as stronger acceleration
than the previous generation.
characteristics for a sportier driving experience.
Mountain – Best deployed when in mountainous terrain (long
grades of 5 percent or steeper) to help to preserve battery
power and maintain higher speeds.
Hold – Forces the Volt into extended range operation to
maintain battery charge.
New features for the 2016 model include:
• Regen-on-Demand™, which can control the vehicle’s
energy regeneration using a paddle on the back of the
steering wheel
• Stronger body structure with more high-strength steel and
a quieter ride
• Improved capability braking system
• 120 V portable charging cord set boasting a simpler,
compact design and more convenient storage location
• Active grille shutters that help balance design with
efficiency
• Available illuminated charge port.
Battery Charging
A new feature for charging
the Volt is programmable
charging using GPS, which
enables owners to be
able to set their charging
preferences exclusively for their
“home” charging location. The vehicle
will automatically adjust to that setting
when it’s at that location. Owners only
have to program the system once and the Volt will return to
those settings every time it’s at the home location.
The Volt also features 10 air bags, a Rear Vision Camera, and
crash-avoidance items such as Lane Change Alert, Rear Cross
Traffic Alert, Forward Collision Alert and Forward Automatic
Braking.
Owners can pre-set their battery charging level at 240 V or
120 V, which can be set on either 8 A or 12 A. They can also
choose whether to begin charging immediately, set a departure
time for each day of the week, or set a departure time and a
utility rate schedule to charge only at off-peak rates.
Driving Modes
Four driving modes are
available on the 2016 Volt,
which are accessed by
pressing the MODE button
on the center console.

Quick Learn Process for
Programming Additional Keys
A new, time-saving quick-learn process is
available for programming additional keys
without using the Service Programming
System (SPS) for keyed GM vehicles in the
U.S. and Canada.
The Adding Keys quick-learn procedure
(Document ID: 3273485 in the GM Service
Information) does not erase any keys prior
to programming. The procedure will simply
program the key into the next available
slot. The new procedure does not apply to
vehicles equipped with a keyless access
system (push-button start).
If a new key is being learned to a vehicle to
replace a damaged, inoperative or stolen key,
the Replacing Keys procedure in the Service
Information must be used. It will erase all the
known keys from the vehicle, so the old key
cannot be used again to access or start the
vehicle.
Adding Keys
The quick-learn procedure requires that one
learned key is available. Eight keys may be
learned to one vehicle. The keys to be learned
must duplicate the mechanical cut of the
current key.
1. With a previously learned key, turn the
ignition on.
2. Turn off the ignition and remove the key.
3. Within 10 seconds of turning off the
ignition, insert the new key to be learned
and turn the key to the On/Run position.
Do not turn the key to the Crank/
Start position. Keep the key in the On/
Run position for five seconds until the
security theft warning lamp on the
instrument cluster turns off, indicating
the vehicle has learned the new key.
Repeat this step for any additional keys.
4. Verify that each key operates properly.
Remove the key from the ignition and
wait 30 seconds. Insert the key into the
ignition and start the vehicle.
The 10-second time limit must be met for
successful programming. Make sure to keep
other keys and transmitters at least 12 inches
from the ignition cylinder while learning
a key. If the key doesn’t work properly,
repeat the quick-learn process, paying close
attention to the time limits.

TECH TIPS
Incorrect Odometer Reading
after BCM Replacement
2003-2007 Saturn ION; 20052010 Chevrolet Cobalt; 20052006 Pontiac Pursuit; 2007-2010
Pontiac G5
After replacing the Body Control
Module (BCM), disconnect
the Instrument Panel Cluster
(IPC) prior to programming
the new BCM. If the IPC is not
disconnected, it may validate
the current mileage (incorrect
in this case) with the ECM and
self-populate the BCM with
the incorrect mileage, which
may require another BCM
replacement.
During the setup procedure, if
the IPC is connected, the scan
tool may prompt the technician
to confirm the current mileage
is correct. If “no” is entered on
the scan tool, the procedure
will end and it will return to the
module setup menu. This does
not indicate a fault with the
replacement BCM.
Disconnecting the IPC from the
BCM before programming will
force the BCM to prompt the
technician to enter the correct
mileage during programming
using a scan tool.
If the incorrect mileage was
transferred to the IPC, try
programming again with the IPC
disconnected. If this procedure
still does not allow the correct
the odometer reading to be
input, the BCM will need to be
replaced again.

Stop Use of Leak Preventative Additives
2011-2017 Chevrolet Volt; 2014-2016 Chevrolet Spark EV, Cadillac ELR; 2016 Chevrolet Malibu Hybrid
The cooling systems in these models use very small orifices
in multiple areas (heater core filter, heater core, thermostat,
radiators, heater plates in the HV battery cells, etc.) for the
cooling systems. Leak preventative products or other additives
used in the cooling systems will clog the small orifices and
reduce the flow of coolant. Disruptions to the cooling systems
can result in multiple part replacements including the entire
HV battery.
2016 Volt
The flushing process described in the appropriate Service
Information is for maintenance and part replacements
only. It does not provide an adequate flushing procedure to
remove the leak preventative product from the small orifices
throughout the two cooling systems.
If a leak preventative product or additive has been used in the:
• Passenger compartment heater system – the heater
core, heater core outlet filter (if equipped), thermostat
and coolant must be replaced. The entire passenger
compartment heater system must be removed to
thoroughly flush/clean the leak product/additive.
• Hybrid/EV battery pack cooling system – the coolant
and Hybrid/EV battery pack may have to be replaced
due to Diagnostic Trouble Codes set for clogged orifices,
overheating, and/or isolation faults. Once the HV battery
is replaced, the entire HV battery coolant system has to
be removed to thoroughly flush/clean the leak product/
additive.
• Hybrid electronics cooling system – the electronic control
modules may have to be replaced. The entire hybrid
electronics cooling system must be removed to thoroughly
flush/clean the stop leak/additive.
If the leak product/additive cannot be properly flushed/
cleaned or it can’t be determined if the product was completely
removed, then the part(s) must be replaced. If any of the leak
product/additive is left behind, the vehicle may experience a
repeat issue when the system is filled with coolant.
The passenger compartment heater, Hybrid/EV battery pack
cooling, and hybrid electronics cooling systems require a 50/50
mix of GM DEX-COOL® and de-ionized water. This mixture is
available in a pre-mix with bitterant. Do not use tap water or
distilled water.
Preventing Vibrations from Wheel Slip
Mounting summer tires or changing from winter tires happens
every year at this time as temperatures rise. If a vibration is
noticed shortly after having a tire or tires mounted, it may be
caused by the tires slipping on the wheels during acceleration
or braking, placing the imbalance point of the tire away from
the weight location.
Wheel slip is most common on clear-coated or chrome wheels
with very smooth bead seat areas, but it may also occur on
other alloy or steel wheels. Most slippage occurs immediately
after mounting.
Wheel slip mark
Wheel slip normally occurs when an excessive amount of
lubricant is used, lubricant is applied in the wrong locations, or

the wrong lubricant is used. Improper lubricants, nonpreferred lubricants or improperly diluted lubricants
may contain excessive moisture or components that do
not dry sufficiently, resulting in an interface between
the tire and rim that is excessively slippery.
Checking for Wheel Slip
Vehicles that return immediately (the vehicle has been
serviced within the last couple of hours) with ride
disturbances and out of balance assemblies should be
checked for wheel slip. Wheel slip can be checked by
placing a temporary mark on the tire at the valve stem.
After driving the vehicle, if the wheel slip is less than
one inch, then wheel slip is probably not contributing
to a ride disturbance. When wheel slip is greater than
one inch and a ride disturbance is felt on the test drive,
wheel slip may be causing the vibration.
Preferred Lubricant
To eliminate wheel slip, the tire beads should normally
only be lubricated from “heel to toe.” Lubricant applied
outside the heel-to-toe zone will cause the tire to have
reduced grip on the wheel and increase the likelihood
of slippage. When lubricating the wheel, lubricate the
safety humps, leave the rim flanges dry and lubricate
the drop center area only for difficult-to-mount tires.
To minimize rim slip, always use commercially available
lubricants made for bead seating to assist in tire
mounting. Paste-type lubes are recommended because
the application can be better controlled and paste
type lubes will not drip onto areas that should not
be lubricated. If lubricants that require dilution are
used, carefully follow the lubricant manufacturer’s
instructions. Under-diluted mixtures will not dry soon
enough, which may cause wheel slip. Over-diluted
mixtures will dry too fast and may hamper proper bead
seating.
Lubricants also must be properly stored. The container
must be kept covered to prevent the evaporation of
drying agents. Always check the lubricant’s expiration
date. Once the expiration date is reached, dispose of
the remaining lubricant.
After tire mounting, the vehicle should not be driven
aggressively (hard acceleration or braking) for up to 24
hours to allow the lubricant to dry and for the tires to
achieve maximum adherence to the wheels.
ACDelco, College Come Together
to Teach Students and Make Repairs
Teamwork manifests itself in
many ways, as illustrated during
an ACDelco training course last
December.
Dustin Smith, a technician at
Southwest Auto in Lincoln,
Neb., was heading to an all-day
engine performance class at
Iowa Western Community
College in Council Bluffs,
Iowa — one of ACDelco’s
South Central Region training
locations — when steam began
billowing out of his 2000
Pontiac Firebird Trans Am.
By the time he arrived at the
school, the diagnosis was clear.
The water pump was in dire
need of replacement.
“Dustin asked what we could
do,” says course instructor
Gerald Mungle. “So I called
Jerry Nissen, the automotive
department chairman, and he
immediately offered a bay in
the school’s shop to park the
vehicle while it cooled down.”
In the meantime, ACDelco
District Manager Herb
Anderson contacted the
local ACDelco warehouse
distributor, Factory Motor
Parts, to check on the
availability of the parts needed.
another automotive technology
instructor, Ross Glandt, offered
to take on the repair.
“My class was busy in the
lab and I didn’t want the guy
to have to mess with his car
during his lunch break,” Glandt
says. “So I started draining
the coolant and taking out the
part.”
Anderson drove to the parts
warehouse in nearby Omaha to
pick up a brand new ACDelco
water pump and, within 90
minutes, Glandt completed the
repair — much to the surprise
and delight of Smith.
“I actually heard my car start
up while I was in class,” Smith
recalls. “It was really a nice
thing to do on everyone’s part.”
For Mungle, this repair
represented a true group
effort. “The college is an A-Plus
operation and Jerry Nissen, in
particular, should get credit for
providing the service bay,” he
says. “Herb Anderson deserves
to be recognized for getting the
part and, of course, Ross Glandt
for putting the pump in so our
student could focus on the class
without worrying about his
transportation home.”
While Smith attended class,
