Hva betyr feilkoden?

The transmission control module (TCM) has lost contact with the high-speed network. CAN communication is blocked by a serious disturbance on the bus, and for as long as this lasts the gearbox control module cannot be communicated with.

Mulige årsaker

Open circuit in one of the CAN wires
Contact resistance or corrosion in connectors and joints
Damaged transmission control module (TCM)
Short circuit between the CAN wires
Internal fault in another control module on the same part of the CAN network

Hva du kan gjøre

1Start by clearing up the stored faults in the CEM and ECM first
2Check connectors and wiring to the gearbox control module for looseness, corrosion and damage
3Have a workshop measure the CAN network, as this needs diagnostic equipment
4Do not replace the central electronic module (CEM) for this code unless the workshop has found an internal fault there
5Clear the code only once the other codes have been fixed and check that it is not set again

Symptomer du kan merke4

Check engine lamp lit
The car performs poorly and lacks power when pulling away from standstill

The automatic gearbox shifts harshly or jerkily

Hva feilen kan påvirke2
