What does this fault code mean?
The CEM has registered an internal fault in its software, for example after a failed software upload. The engine may then not start. The fault is normally put right with new software or by replacing the module, and that is done by a workshop.
Possible causes
- Faulty software loaded in the CEM
What you can do
- 1Clear the fault code and start the car. If the fault returns straight away, it is an active software fault
- 2Tell the workshop if a software update was recently interrupted or failed, since that is an important clue
- 3Have a workshop read the fault codes and reload the CEM with the latest software. Programming is a workshop task
- 4If reprogramming has no effect, the CEM must be replaced, which is also a workshop task
- 5Make sure the battery is well charged during the upload, since low voltage can interrupt it
- 6After the work, check that the engine starts and that the fault code does not return
Symptoms you may notice1
- The engine does not start
