Test Notes

RH 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, air bag diagnostic monitor reference ground). If the air bag diagnostic monitor measures a difference of more than 2.0 ohms between Pin 20 (Circuit 618, P/LG) and Pin 3 (Circuit 57, BK), it will flash out diagnostic trouble code 44.

Note that Circuit 618 (P/LG) is attached to the side of the RH primary crash sensor case. In addition, the case is grounded to the vehicle. Note that Circuit 618 is spliced into a circuit going to Pin 21 of the air bag diagnostic monitor.

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 diagnostic monitor harness connector to RH primary crash sensor. Note that Circuit 618 is spliced into a wire going to Pin 21 of the air bag diagnostic monitor. Also, Circuit 618 goes through an in-line connector before reaching the RH primary crash sensor connector.

3. An open circuit inside RH primary crash sensor.
