DTC EFI-335

3-3-5 CABLE FAULT BETWEEN AW 50-42 AND MOTRONIC 4.4





Trouble Code Conditions
- The automatic transmission control module (TCM) can request the lighting of the malfunction indicator lamp (MIL) by transmitting a signal to the engine control module (ECM).
- Diagnostic trouble code (DTC) EFI-335 is stored if the engine control module registers a fault in the signal cable. When the engine is started the engine control module checks for a short-circuit to supply voltage or open-circuit (high signal) in the signal cable. When the engine is running, the engine control module checks for a short-circuit to ground in the signal cable (low signal).

Substitute value(s)
- None.

Possible source(s)
Signal too high:
- Open-circuit in signal cable.
- Short-circuit to supply voltage in signal cable.

Signal too low:
- Short-circuit to ground in signal cable.

Fault symptom(s)
