What does this fault code mean?
The control module sends and receives information on the CAN network all the time. The code is set when messages passing between the module and the CEM are wrong. The cause may be loose connections, contact resistance or oxidation at the connections, or an open circuit in the CAN wiring between the control module and the CEM.
Possible causes
- Loose connections, contact resistance or oxidation at the connections.
- Open circuit in the CAN wiring running to the CEM.
What you can do
- 1Check that the connections in the extended CAN network are firmly seated and not corroded.
- 2With a diagnostic tool, clear the fault codes in all control modules, let the car run for a while, then read the fault codes again.
- 3Have a workshop measure the voltage drop in the CAN wiring and look for short circuits, since this needs measuring equipment.
Symptoms you may notice3
