Normal Operation

NOTE: Circuit 935 (BR/W) is attached to the side of the center air bag sensor case. In addition, the case is grounded to the vehicle.

The air bag diagnostic monitor measures the resistance between Pin 21 (circuit 935 BR/W) and Pin 3 (air bag diagnostic monitor reference ground). If the air bag diagnostic monitor measures a difference of more than 2.0 ohms between Pin 21 and Pin 3, it will flash a code 45.
