6.2 DDEC alarms
The DDEC generates alarms which are indicated in different ways depending on the equipment configu‐
ration:
• Two-digit flash code
• Fault code and text on a display or PC screen
To facilitate troubleshooting without additional auxiliary equipment, the two-digit flash codes can be read
out from the DDEC by means of the vehicle-side alarm lamps CHECK ENGINE LIGHT (yellow) and
STOP ENGINE LIGHT (red).
For this purpose, two DIAGNOSTIC REQUEST switches must be provided in the vehicle). The first
switch is used for reading out the flash codes of the master DDEC unit, the second one to read out the
receiver DDEC unit. The flash-code signals from master and receiver are transmitted to the same alarm
lamps.
Active codes:
Inactive codes:
indicated by STOP ENGINE LIGHT (red)
indicated by CHECK ENGINE LIGHT (yellow)
Activation of flash codes:
1. Operate IGNITION switch to position ON.
2. Operate DIAGNOSTIC REQUEST switch of master or receiver unit.
3. Read off codes.
4. Identify the fault according to the DDC fault code list.
Example:
Active code 23:
Inactive code 34:
STOP ENGINE LIGHT lamp
CHECK ENGINE LIGHT lamp

Flashing phase 1
Flashing phase 2
Flashing phase 1
Flashing phase 2
ОО
ООО
ООО
ОООО
two times flashing
three times flashing
three times flashing
four times flashing
There is a pause of 0.5 seconds between the flashing phases 1 and 2. When a fault code changes from
active to inactive, the pause is 3 seconds.
To terminate flash code indication, switch DIAGNOSTIC REQUEST and IGNITION switches off.
IGNITION is allowed to be switched on again only after 30 seconds.
This method does not allow exact fault diagnostics, since a flash code may indicate faults with several
causes.
The Diagnostic Data Reader (DDR) is intended to:
• Read out alarms from the DDEC electronic system
• Change parameters (limited extent)
The DDR provides the possibility to read out active and inactive fault codes via separate menus. Addi‐
tionally, the inactive fault codes stored in the DDEC can be deleted.
For detailed functional description, refer to the description of the DDR.
The DDR (Part No. 5355383601/77) consists of:
• the Pro Link 9000 basic unit
• the MPC Cartridge to integrate a PCMCIA card
• a PCMCIA card
• a connection cable
• an additional adapter cable is required (Part No. J 38500 60A)
TIM-ID: 0000003162 - 001
The Diagnostic Data Reader (DDR) facilitates more detailed troubleshooting.
Accessory equipment:
• Printer (Part No. J-38699) for direct connection to the DDR
• Spare paper (Part No. J-38480-5) for printer (5 rolls)
The following information will be available by reading out fault codes with the DDR.

SID (Subsystem Identification Character)
• Identifies the origin of alarms from subsystems, which can be replaced as a complete unit (e.g. injec‐
tors).
FMI (Failure Mode Identifier)
• Identifies the type of fault.
FMI 0 → Measured value exceeds the limit value (monitoring for TOO HIGH), example: Coolant tem‐
perature
FMI 1 → Measured value does not reach the limit value (monitoring for TOO LOW), example: Lube oil
pressure
FMI 3 → Signal path interrupted or signal is exceeds the permissible measuring range (sensor defect)
FMI 4 → Signal path short circuit against (-) supply of sensor or signal does not reach permissible
measuring range (sensor defect)

Instructions and comments on endoscopic and visual examination of cylinder
liners
Terms used for endoscopic examination
Use the terms listed below to describe the condition of the cylinder-liner surface in the endoscopic exami‐
nation report.
Findings
Measure
Light scoring
Minor dirt scores can occur during the assembly of a new engine (honing prod‐
ucts, particles, broken-off burrs). Removed cylinders clearly exhibit such scor‐
ing on the running surface under endoscope magnification. Cannot be felt with
the fingernail.
Findings not critical.
Single scores
Clearly visible scores caused by hard particles. They usually start in the TDC
area and cross through the honing pattern in the direction of stroke.
Scored area
These areas consist of scores of different lengths and depths next to one an‐
other. In most cases, they are found at the 6-o'clock and 12-o'clock positions
(inlet/exhaust) along the transverse engine axis.
Smoothened area
Smoothened areas are changes to the running surface but almost the whole
honing pattern is still visible. Smoothened areas appear brighter and more bril‐
liant than the surrounding running surface.
Polished area
Polished areas are on the running surface and show local removal of the hon‐
ing pattern. Grooves from the honing process are not visible any more.
New cylinder liners must be fitted in the following cases
Polished area:
covers more than 20% of the entire piston running surface,
covers more than 30° of the circumference and extends over more than 50%
of piston stroke,
is wider than 15 mm over the entire piston stroke.
Discoloration
This is caused by oxidation (surface discoloration through oil or fuel) and tem‐
perature differences around the liner. It appears rather darker within the honed
structure in contrast to the bright metallic running surface. The honing pattern
is undisturbed. Discolorations extend in stroke direction and may be interrupt‐
ed.
TIM-ID: 0000003285 - 003
Corrosion fields / spots Corrosion fields / spots result from water (condensed water) with the valves in
the overlap (open) position. They are clearly visible due to the dark color of the
honing groove bottom.
This corrosion is not critical unless there is corrosion pitting.
Black lines
Black lines are a step towards heat discoloration. They are visible as a clear
discoloration from TDC to BDC in the running surface and the start of localized
damage to the honing pattern.
Cylinders with a number of black lines around the running surface have limited
service life and should be replaced.
Findings
Measure
Discolorations (Heat)
These are caused by a disturbance in the liner / ring tribosystem. Usually they
run over the whole ring-travel area (TDC/BDC), starting at the first TDC-ring
and becoming more visible from the second TDC-ring onwards and less pro‐
nounced from TDC-ring 1. The honing pattern is usually no longer visible and
displays a clearly defined (straight) edge to the undisturbed surface. The dam‐
aged surface is usually discolored. The circumferential length varies.
Liners with heat discoloration starting in the TDC-ring 1 have to be replaced.
Seizures, Seizure
marks
Seizure marks are of irregular circumferential length and depth. Can be
caused by either the piston skirt or the piston crown. Material deposits on the
liner (smears) show heavy discoloration and scoring.
Replace liner.
Evaluation of findings and further measures
TIM-ID: 0000003285 - 003
The findings in the start phase of oxidation discoloration and heat discoloration are similar. Thorough in‐
vestigation and compliance with the above evaluation criteria allows a definite evaluation. To avoid un‐
necessary disassembly work, it is recommended that another inspection be carried out after further oper‐
ation of the engine.
