What does this fault code mean?
The ADM has recorded a message fault on the data network: the main fuel level signal is invalid. The signal comes from the central electronic module (CEM), so the code is usually linked to the CEM. Clear it only after the CEM has been traced.
Possible causes
- Fault in the central electronic module (CEM) or in the message it sends
What you can do
- 1Read the codes in the central electronic module (CEM) first and deal with them
- 2Clear the code only after the fault in the CEM has been fixed
- 3Check the battery and its terminals, since voltage problems can disturb the data network
- 4If the fault remains, have a workshop with diagnostic equipment check the data network and the CEM
