DTC 44: RH Primary Crash Sensor Not Mounted Properly
DIAGNOSTIC TROUBLE CODE 44RH Radiator Primary Crash Sensor Not Mounted To Vehicle Properly
Normal Operation
The diagnostic monitor measures the resistance between Pin 20 (Circuit 618, P/LG) 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 out code 44.
Note that Circuit 618 (P/LG) is grounded to the side of the RH radiator 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, dirt, or corrosion at the RH radiator primary crash sensor mounting location.
2. An open or damaged wire in Circuit 618 (P/LG) from Pin 20 of the diagnostic monitor harness connector to primary crash sensor.
3. An open circuit inside RH radiator primary crash sensor.
