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.
