Was bedeutet der Fehlercode?
The transmission control module (TCM) and the engine control module communicate over the CAN network, using the CAN H and CAN L wires. The code is set when the transmission control module detects that the CAN wires are shorted to ground. It belongs to a group of codes for faults on the same wires, and this one covers a short to ground.
Mögliche Ursachen
- Short to ground in the CAN wires
Was Sie tun können
- 1Read the code, clear it and road test the car to see whether it comes back
- 2With the ignition off, check the CAN wiring between the gearbox and the engine for chafing, damage and loose connectors
- 3Use a multimeter to check that the CAN wires have no contact with ground (the body)
- 4Check the connectors at both control modules for contact resistance and oxidation
- 5Have a workshop check CAN communication with diagnostic equipment and replace a control module if the fault remains after the wiring has been checked
