Test Notes

Safing Sensor Not Mounted to Vehicle Properly

Normal Operation
The DB/W wire (Circuit 613) in the LH kick panel safing sensor is grounded to the side of the LH kick panel safing sensor housing, and the housing is grounded to the vehicle. A resistor inside the air bag diagnostic monitor is connected to Pin 16 and a 5-volt reference voltage. If Circuit 613 (DB/W) is properly grounded, the voltage at Pin 16 will be zero volts. If the voltage on Pin 16 is greater than 0.7 volt, the air bag diagnostic monitor may flash diagnostic trouble code 21, indicating that the LH kick panel safing sensor is not grounded properly to the vehicle.

POSSIBLE CAUSES

High voltage at Pin 16 can be caused by:

1. A poor connection due to loose mounting or dirt at the LH kick panel safing sensor mounting surface.

2. An open or damaged wire in Circuit 613 (DB/W) from Pin 16 of the air bag diagnostic monitor connector to the LH kick panel safing rear air bag sensor and bracket.

3. An open circuit inside the LH kick panel safing sensor.
