44: RH Primary Crash Sensor Not Mounted Properly

DIAGNOSTIC TROUBLE CODE 44 - RH PRIMARY CRASH SENSOR NOT MOUNTED TO VEHICLE PROPERLY

Normal Operation

NOTE: 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.

The air bag diagnostic monitor measures the resistance between Pin C2-21 and the reference ground at Pin C1-18. If the air bag diagnostic monitor measures a difference of more than 3.0 ohms between the ground at Pin C1-18 and the ground at Pin C2-21, the air bag diagnostic monitor will store in memory and flash a DTC 44 on the AIR BAG indicator. Should the difference in resistance between Pin C1-18 and Pin C2-21 be serviced or otherwise reduced to less than 3.0 ohms, a DTC 84 will be stored in memory.

Possible Causes
A high resistance reading on Pin C2-21 to ground can be caused by:
- A poor attachment of RH primary crash front air bag sensor and bracket due to loose mounting, dirt, or corrosion at its mounting location.
- An open or damaged wire in Circuit 618 (P/LG).
- An open wire or loose rivet inside RH primary crash front air bag sensor and bracket.
- A poor reference ground at Pins C2-10 and C1-18 of the air bag diagnostic monitor in Circuit 57 (BK).
