Applies to the following models:

What does this fault code mean?
The control modules in the car communicate with each other over CAN, a standardised serial communication method. The module has registered that communication with the driver information module (instrument cluster) is disturbed or missing, and the code is set as a result. The code points to a fault in communication across the network rather than in a single module.
Possible causes
- The driver information module has no power supply
- The ground wire to the driver information module is open
- Open circuit or short circuit in the CAN wiring
- Contact resistance, oxidation or poor contact in the connections
- The driver information module or another module is not meant for this car, such as a second-hand unit with other software or hardware
- Several codes for communication faults in the central electronic module (CEM) point to a common fault in the CAN network
What you can do
- 1Read and clear the code, then start the car to see whether it comes back
- 2Check the fuses in the fuse box and make sure they are intact
- 3If you have diagnostic equipment, read the codes in the central electronic module (CEM) first, as they show whether more parts of the network are affected
- 4Check that the connectors at the instrument cluster and the earth point behind it are secure and free from moisture and oxidation
- 5Have a workshop measure and trace the CAN wiring; do not replace any control module unless tracing shows that it is damaged
Symptoms you may notice1
- No noticeable symptoms for the driver
