Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information FSM-C1A6776

Condition
The forward facing radar can compensate for a vertical distortion of up to 1.5 degrees. 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 facing radar is no longer correctly aimed straight ahead due to mechanical, vertical distortion.
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.

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.
