This chapter explains how to begin the scan tool’s basic setup and test functions. This
information is specific to Chrysler vehicles. For general scan tool functionality, see the user’s
manual appropriate to your diagnostic tool.
For additional information on Chrysler vehicles, see the following sections:

3.1 Identifying a Vehicle
Many late-model vehicles have an automatic vehicle identification (ID) function that identifies
the test vehicle based on information transmitted on the serial data stream. For others, the
vehicle must be manually identified by entering specific vehicle identification number (VIN)
characters into the scan tool.

Chapter 3
Identifying a Vehicle
3.1.1 Manual Identification
You must manually enter the vehicle ID for all 1995 and earlier vehicles. You may also
manually identify automatic ID systems.
Note the following when manually identifying Chrysler vehicles:
• Because of midyear manufacturing changes in engine computer systems, you should
always enter a new identification when you test a different vehicle, even when two
vehicles are the same year, model, and have the same engine and accessories.
• Models with Mitsubishi-built engines must be identified as an Asian Import.
• The following models were built using 1986 logic modules:
– Some 1987 Sundance and Shadow (P-body) models with turbocharged engines
– Some 1987 Omni, Horizon, and Charger (L-body)
Vehicle identification for these models should be entered into the scan tool as 1986
models (10th VIN character G for 1986, instead of H for 1987). A 1986 logic module can
be identified by the MAP sensor mounted on the module case. The 1987 logic modules
use MAP sensors mounted in the engine compartment.
• To test Jeep vehicles with the US Domestic software:
– 1990 and later—select CHRYSLER from the manufacturer selection menu
– 1989 and earlier—select JEEP from the manufacturer selection menu
• Many 1983 and later Chrysler imports, except Maserati TC, are tested with the Asian
Import software. The US Domestic software does not test these vehicles, which often
have “Diamond Star” imprinted on the body label attached to the firewall.
The vehicle ID process begins from the Software Confirmation menu (“To manually ID a
vehicle:” on page 6).

3.3 Connecting to the Vehicle
Once a vehicle has been identified and a system has been selected, a scan tool connection
message instructs you to use the vehicle test adapters supplied to connect the scan tool for
testing (Figure 3-10).
CONNECT OBD-II K13 ADAPTER TO CONNECTOR
LOCATED UNDER LEFT SIDE OF DASH, NEAR
HOOD RELEASE.
PRESS Y TO CONTINUE.
Figure 3-10 Sample Chrysler connection message
Each test adapter plugs into a specific vehicle diagnostic connector and attaches to one end
of the data cable. The other end of the data cable attaches to the scan tool.
The following adapters are available to test Chrysler vehicles:
• CHRY-1—(MT2500-30) engine test adapter (except LH cars)
• CHRY-2—(MT2500-31) body, ABS, transmission, and LH-car engine test adapter
• MITSU-1—(MT2500-55) Mitsubishi engine and transmission test adapter (used for
Avenger, Sebring, and Talon)
• OBD-II—(MT2500-46) 16-pin adapter for vehicles with the 16-pin OBD-II connector
– The K-7 Personality Key™ device must be installed into the OBD-II adapter when
used with MITSU-1 for the Avenger, Sebring, and Talon.
– The K-13 Personality Key™ device must be installed for all other Chrysler
applications

Connecting to the Vehicle
The CHRY-1 test adapter has a socket for connecting the battery power or cigarette lighter
power cables. A power cable is not required with the CHRY-2 and the OBD-II test
adapters.Table 3-2 contains connector locations for Chrysler vehicles.
