44 : RH Primary Crash Sensor Not Mounted Properly
DIAGNOSTIC TROUBLE CODE 44RH Primary Crash Sensor Not Mounted to Vehicle Properly
Normal Operation
The air bag diagnostic monitor measures the resistance between Pin 20 (Circuit 618, P/LG) and Pin 3 (Circuit 57, BK, diagnostic monitor reference ground). If the air bag diagnostic monitor measures a difference of more than 2.0 ohms between Pin 20 and Pin 3, air bag diagnostic monitor will flash out code 44.
Note that Circuit 618 (P/LG) is riveted to the side of the RH primary crash sensor case and the case of the sensor is grounded to the vehicle at its mounting point.
Possible Causes
High resistance on Pin 20 (Circuit 618, P/LG) to ground can be caused by:
1. A poor connection due to loose mounting or dirt at the RH primary crash sensor mounting location.
2. An open or damaged wire in Circuit 618 (P/LG) from Pin 20 of the air bag diagnostic monitor harness connector to RH primary crash sensor.
3. An open circuit inside RH primary crash sensor.
