Test Notes

Normal Operation
The diagnostic monitor measures the resistance across Pin 8 (Circuit 614B (GY/O)) and Pin 9 (Circuit 616 (PK/BK)) every time the ignition switch is turned to the ON position. Normal resistance across these circuits is between 0.9 ohm and 1.1 ohms. This resistance comes from the passenger side air bag itself. If the resistance across Pins 8 and 9 is less than 0.7 ohm, the monitor will flash a code 35.

NOTE: The connectors for the air bag and air bag harness have metal spring clips that act as shorting bars. These shorting bars are built into the plastic hardshell connectors on the back of the passenger side air bag and the air bag harness. The shorting bars are designed to short the terminals together when the connector is not mated. DO NOT attempt to remove the air bag shorting bar and measure the resistance of the air bag.

Possible Causes
Low resistance across Pins 8 and 9 can be caused by:

Vehicle not equipped with a passenger side air bag:
1. A jumper wire installed across passenger air bag harness connector. The passenger air bag connector should be empty or have a resistance of at least 1.0 ohm across the connector terminals.

Vehicle equipped with a passenger side air bag:
1. A poorly mated passenger air bag harness connector may not push the shorting bars back into their fully retracted positions.
2. A damaged shorting bar may short Circuits 614 (GY/O) and 616 (PK/BK) together.
3. A short across the passenger air bag terminals within the air bag. DO NOT attempt a direct resistance measurement of the air bag. Follow the diagnostic procedures to determine if the air bag resistance is lower than normal.
4. A short in the wiring harness between Circuit 614 (GY/O), 614B (GY/O) and 616 (PK/BK).
