Diagnostic Trouble Code (DTC) Information FSM-C1A6787
Condition
Forward Sensing Module (FSM) communicates with forward-sensing radar.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- No communication with the forward facing radar.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Control module supplied with power for at least 5 seconds.
- The system voltage is greater than 8.0 V.
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.
