DTC 33: Passenger Side Air Bag Circuit High Resistance or Open

Electrical Schematic:

Normal Operation
The air bag diagnostic monitor measures the resistance across Pin 9 and Pin 11 every time the ignition switch is turned to the ON position. Normal resistance across these circuits is between 0.9 ohms and 1.1 ohms. 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 a code 33 on the air bag warning indicator.

NOTE: The connector for the air bag module has a metal spring clip that acts as a shorting bar. This shorting bar is built into the plastic hardshell connector. The shorting bar is depressed to short circuits 944C and 939 together when the connector is not mated. Do not attempt to remove the air bag shorting bar and measure the resistance of the passenger side air bag module.

Possible Causes
A high resistance or open in the passenger side air bag module circuit can be caused by an open circuit or high resistance on the wiring harness in circuit 939 ("GN/Y") or 944A ("GN/R").
