B1D0F-DRIVER MIRROR HORIZONTAL POSITION SENSOR INPUT CIRCUIT LOW





For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
Continuously.

- Set Condition:
The (P65) Driver Mirror Horizontal Position Signal circuit supplies input to the Driver Door Module. The DTC B1D0F will set if the input value is less than the known good (stored) value for more than 60 ms.





1. TEST FOR INTERMITTENT CONDITION
