Co oznacza ten kod błędu?

The engine control module (ECM) gets signals from the forward sensing module (FSM) and the central electronic module (CEM) and applies braking help when a collision threatens. The code is set when one of the input signals from the FSM is lost. The code indicates that communication between the FSM and the engine control module is not working properly.

Możliwe przyczyny

The fault is in the forward sensing module (FSM)
Open circuit in the communication cable
Communication cable short-circuited to ground or to voltage
Contact resistance or oxidation in the connections
Open circuit or short-circuit in the connections

Co możesz zrobić

1Read the fault codes in the engine control module. If any of ECM-U012088, ECM-U000188, ECM-U1A1400, ECM-U000108 or ECM-U000100 is stored, check it first.
2Read the fault codes in the FSM. If it has a code of its own, that is likely the root cause and the engine control module code is a follow-on fault.
3Check that the connectors between the engine control module and the FSM are secure and clean, and look for chafed wiring.
4If the code returns, have a workshop troubleshoot the FSM with diagnostic equipment, as this requires measurement.
