What does this fault code mean?
The fault code means that CEM receives an incorrect answer from the keyless vehicle module (KVM) when a passive start is attempted. The fault may lie in the remote key or in the KVM, and the engine may then not start with the keyless function. The fault concerns the keyless start function.
Possible causes

- Internal fault in the remote key
- Internal fault in the keyless vehicle module (KVM)
What you can do

- 2If the remote key battery is old, replace it and try again, or try a second remote key if you have one
- 3If you have a diagnostic tool, check that communication with the KVM works
