Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information DEM-U210100

Condition

The diagnostic trouble code (DTC) is stored if the control module detects that:
- The control module's configuration does not correspond with the vehicle's vehicle configuration.
- Incorrect value lasts longer than 25 seconds.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition on.

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.

- None.
