Test Notes
Normal OperationNOTE: 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 hardshell connector on the back of the passenger side air bag module assembly. The shorting bar is designed to short the passenger air bag terminals together when the connector is not mated. DO NOT attempt to remove the passenger side air bag module shorting bar and measure the resistance of the passenger side air bag module.
The air bag diagnostic monitor measures the resistance across Pin C2-8, Circuit 614 (GY/O) and Pin C2-9, Circuit 616 (PK/BK) every time the ignition switch is turned to RUN. Normal resistance across these circuits is between 0.9 ohm and 1.1 ohm. This resistance comes from the passenger side air bag module itself. If the resistance across Pin C2-8 and C2-9 is less than 0.7 ohm, the air bag diagnostic monitor will flash DTC 35. If low resistance is measured across Pins C2-8 and C2-9, DTC 35 will appear.
Possible Causes
Low resistance across Pins C2-8 and C2-9 can be caused by:
1. A poorly mated passenger side air bag module harness connector not pushing 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 passenger side air bag module assembly. DO NOT attempt a direct resistance measurement of the air bag. Follow the diagnostic procedures to determine if the passenger air bag resistance is lower than normal.
4. A short in the wiring harness between Circuit 614 (GY/O) and 616 (PK/BK).
