Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ICM-U010100

The diagnostic trouble code (DTC) is stored if the control module detects that:
- No communication with the Transmission control module (TCM).
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Activated control module.

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.
