Test Notes

Passenger Side Air Bag Circuit High Resistance or Open

Normal Operation

NOTE: The connector for the passenger side air bag module assembly 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 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 assembly.

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 these two circuits exceeds 4.0 ohms, the air bag diagnostic monitor will flash DTC 33.

Possible Causes
A high resistance or open in the passenger side air bag assembly circuit can be caused by:
1. An open circuit or high resistance in the wiring harness in Circuit 614 (GY/O) or 616 (PK/BK).
2. An open circuit or high resistance in the passenger side air bag module assembly. DO NOT attempt a direct resistance measurement of the passenger side air bag module assembly. Follow the diagnostic procedures to determine if the air bag resistance is higher than normal.
