Test Notes

Normal Operation

NOTE: The connector for the passenger side air bag module has a metal spring clip that acts as a shorting bar. This shorting bar is built into the plastic hard-shell connector on the back of the passenger side air bag module. The shorting bar is designed to short the air bag terminals together when the connector is not mated. Do not attempt to remove the passenger air bag shorting bar and measure the resistance of the passenger side air bag module.

The air bag diagnostic monitor measures the resistance across pin 8 (circuit 611, GN/Y) and pin 9 (circuit 613, BK/GN) every time the ignition switch is turned to ON. Normal resistance across these circuits is between 0.9 ohm and 1.1 ohms. This resistance comes from the passenger side air bag module itself. If low resistance is measured across pins 8 and 9, the air bag diagnostic monitor will flash Diagnostic Trouble Code (DTC) 35.

Possible Causes
Low resistance across pins 8 and 9 can be caused by:
- A poorly mated passenger air bag connector not pushing the shorting bars back into their fully retracted positions.
- A damaged shorting bar may short circuits 611B (GN/Y) and 613 (BK/GN) together.
- A short in the wiring harness between circuits 611 and 613.
- A short across the passenger air bag module terminals within the passenger side air bag module. Do not attempt a direct measurement of the passenger side air bag module. Follow the diagnostic procedures to determine if the passenger side air bag module resistance is lower than normal.
