Was bedeutet der Fehlercode?
The CEM registers CAN H in the high speed network as short-circuited to supply voltage. Throttle response and performance can then suffer, and the transmission control module (TCM) runs with limited function. The fault most often lies in the high speed network wiring.
Mögliche Ursachen
- Short to supply on the high speed network
Was Sie tun können
- 1Check whether performance is reduced and whether any warning lamp is lit. This helps you judge how much of the car is affected
- 2Check the harness in the high speed network for chafing, pinch damage and moisture
- 3With a diagnostic tool, read the fault codes from all control modules and see which ones show communication faults
- 4Use a multimeter to check that the CAN H wire has no contact with supply voltage when it should not
- 5Check the connectors in the high speed network for loose connections and corrosion
- 6With the car in limp mode, do not drive far or in heavy traffic; have a workshop repair the fault
Symptome, die Sie bemerken können5
- The malfunction indicator lamp is lit
- Performance is reduced
- The accelerator pedal responds poorly
- Radio interference
- A message appears in the text display
Was der Fehler beeinflussen kann1
- The transmission control module (TCM) runs with limited function
