Normal Operation

The air bag diagnostic monitor measures the resistance across Pin 10 (circuit 937 GY) and Pin 11 (circuit 944A GN/R) every time the ignition switch is turned to the ON position. Normal resistance across these circuits is between 1.5 ohms and 2.0 ohms. This resistance comes from the air bag itself (approximately 1.0 ohm) and the air bag sliding contact windings (approximately 0.25 ohms to 0.5 ohms per winding, two windings in all). If the resistance across these three circuits exceeds 4.0 ohms, the air bag diagnostic monitor will flash a code 32.

NOTE: The connectors for the air bag and the air bag sliding contact have metal spring clips that act as shorting bars. These shorting bars are built into the plastic hard shell connectors. The shorting bars are designed to short circuits 944A and 937 together when the connectors are not mated. Do not attempt to remove the air bag shorting bar and measure the resistance of the air bag.

The air bag sliding contact shorting bar may be removed to measure the air bag sliding contact resistance. Use extreme care when reinstalling the shorting bar to ensure it is installed correctly.
