Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information FSM-C1A6778

Condition
Forward Sensing Module (FSM) communicates with forward-sensing radar. The forward sensing module (FSM) checks information from the forward-aimed radar.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The forward looking radar does not find the targets during the stationary calibration.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition position II or engine running.

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.
