Diagnostic Trouble Code (DTC) table


Following are all the possible malfunctions that can be recognized by the Engine Control Module (ECM) -J192- and
printed on the VAG 1551 scan tool printer, listed according to code identifier ( SAE and VAG codes).
Malfunctions that switch the MIL on never or immediately are set as "sporadic" each time the engine is started. If the
malfunction occurs again, the "sporadic" status is set again. For malfunctions that only switch the MIL on after two trips
with malfunction, the "sporadic" status is only erased after an OK diagnosis.
If the MIL lights up with engine running, there is a malfunction that makes the exhaust gas worse. If the MIL lights up and
the engine is running, there must in any case be a malfunction stored in the DTC memory of the engine control module
and/or of the transmission control module. In this case, the DTC memory of the engine control module and/or the
transmission control module must be checked.
If the MIL starts to blink, there is a malfunction present that can lead to three way catalytic converter damage (e.g.
combustion misfiring with high misfiring rate). In this case, the trip should be continued with reduced power (until the MIL
goes out or lights up continuously) and the malfunction should be eliminated as quickly as possible.
The malfunction is not stored in the DTC memory immediately and the MIL is not switched on immediately with some
malfunction types, but only after two successive trips with or without preceding cold start (-10 to 30 C (14 to 86 F)
and malfunction occurring (malfunction recognition twice). The MIL switching condition is always specified in the Diagnostic Trouble Code (DTC) table.
Combustion misfiring with high misfiring rate is displayed immediately with the MIL blinking, since the three way catalytic
converters can be damaged. In this case, driving should continue only with reduced power and the malfunction should be
eliminated as soon as possible.

If faulty components are found, also check wiring to the components according to wiring diagram for short and open
circuit.
Before repairing or replacing components, check ground connections for Engine Control Module (ECM) -J192- connector
D on terminals 3, 7 and 12 and connector E on terminals 3, 7 and 11 (specified value approx. 0.5 ) and ground points on
the engine for corrosion and damage, check fuel pump relay Repair Group 24.
