Was bedeutet der Fehlercode?

The transmission control module (TCM) and the engine control module exchange information over the CAN network, which has two signal wires, CAN H and CAN L. The code is set when the transmission control module detects that the CAN wires are shorted to supply voltage. It is one of several codes for faults on the same wires, and this one covers a short to positive.

Mögliche Ursachen

Short to supply voltage 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 are not shorted to positive
4Check the connectors at the transmission control module and the engine control module 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
