DTC 44 - RH Crash Sensor Not Mounted to Vehicle Properly

Electrical Schematic:






Normal Operation

NOTE: Circuit 936 ("BR/Y") is attached to the side of the RH crash sensor case. In addition, the case is grounded to the vehicle.

The diagnostic monitor measures the resistance between pin 20 (circuit 936 "BR/Y") and pin 3 (diagnostic monitor reference ground). If the diagnostic monitor measures a difference of more than 2.0 ohms between pin 20 and pin 3, it will flash a code 44.

Possible Causes
High resistance on pin 20 (circuit 936 "BR/Y") to ground can be caused by:
1. A poor connection due to loose mounting, dirt, or corrosion at the RH crash sensor mounting location.
2. An open or damaged wire in circuit 936 ("BR/Y") from pin 20 of the diagnostic monitor harness connector to the RH crash sensor.
3. An open wire or loose "BR/Y" wire attachment inside the RH crash sensor.
