Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-B10D794

Condition
When the remote key is inserted in the ignition, the Start control module (SCU) tries to read out the remote key's ID from the transponder. If the read-out is not successful within a pre-defined time, a message is sent to the Central electronic module (CEM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Start control module (SCU) reports that remote key does not answer.

Note! The diagnostic trouble code (DTC) can also be stored if something, e.g. a finger is inserted into the starter module.

The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- All ignition positions.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.
