Got a 32 code for the airbag indicator on my dash, 96 explorer. Replaced the clock spring, but still have the 32 code. Noticed the lead that runs to the ign switch. Is it possible the ign switch is bad?

 

got a 32 code on my airbag for a 96 explorer, 4X4. pic'd up a new clock spring and installed it. still getting a 32 code. I've isolated down to either a defective clock spring from the dealer (open box) or an issue further up the harness where the previous car alarm sys was tapped. Alarm sys was disconnected and pulled out several years ago, so I don't suspect it's the problem. We've all had defective parts outa the box, so I'm leaning that direction. I'd like to get a hold of the wiring diagram so I can check the resistance through the bag and steering wheel. I believe 3.5 ohm is the limit, but need to color code for the feed and return. Can anyone help??

 

All I can really offer is be careful of the wires in the yellow shroud, they are for the air bags. If you pulse a ground I believe it is, the bag will deploy. Also, what scanner are you using. In 1996 OBD2 became manditory, and I believe the airbag system is not directly tied into all of that. Once a SRS code has been established, you need a specialized scan tool to release and clear the code. The wiring maybe okay, but the code will not clear on it own.

 

Do not attempt to remove the air bag shorting bar and measure the resistance of the air bag module.

DTC B1932: DRIVER SIDE AIR BAG CIRCUIT HIGH RESISTANCE OR OPEN -- LAMP FAULT CODE 32

Normal Operation

Note: The air bag connector, air bag diagnostic monitor harness connector and the air bag sliding contact connector have metal spring clips that act as shorting bars. These shorting bars are built into the plastic hardshell connectors. The shorting bars are designed to short Circuits 614 (GY/O) and 615 (GY/W) 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. Likewise, the shorting bar(s) in the air bag diagnostic monitor harness connector may be removed by removing the black spacer (locking wedge) from the connector. Use extreme caution when reinstalling the shorting bars to make sure they are installed correctly.

While the ignition switch is in the RUN position, the air bag diagnostic monitor runs periodic checks on the resistance of the driver and passenger air bag circuits.

Normal resistance from Pin C1-2, Circuit 614 (GY/O)(driver air bag feed) to Pin C1-3, Circuit 615 (GY/W)(driver air bag return) is between 1.4 ohms and 2.0 ohms. This resistance total results from the sum of the components in the circuit: the air bag module (approximately 1 ohm) and the air bag sliding contact (0.20 ohm to 0.35 ohm per winding, 2 windings total) plus a small amount of resistance due to the wire itself, crimps, etc.

If the resistance across these two pins exceeds 3.0 ohms, the air bag diagnostic monitor will interpret this as high resistance and the air bag diagnostic monitor will store in memory DTC B1932 and flash out on the air bag indicator a lamp fault code 32.

If the high resistance is later serviced or otherwise falls into the normal range, DTC B1932 will be stored in memory.

Possible Causes

Excessive resistance across Pins C1-2, Circuit 614 (GY/O) and C1-3, Circuit 615 (GY/W) can be caused by:

l A poor connection or corrosion where the air bag sliding contact connects into the main wiring harness. The air bag sliding contact connector at the base of the steering column may have excessive resistance between the male and female terminals in the connector. Also, corrosion may occur on the terminal crimps on both the air bag sliding contact terminals and the main wiring harness terminals.

An open circuit or high resistance in the air bag sliding contact windings inside the air bag sliding contact.

An open circuit or high resistance in the wiring harness in either Circuit 614 (GY/O) or Circuit 615 (GY/W).

An open circuit or high resistance in the driver side air bag module. Do not attempt a direct resistance measurement of the air bag. Follow the diagnostic procedure to determine if the air bag module resistance is higher than normal.

exactly what I was looking for. I found similar info for a 96 mustang, but wanted to insure the explorer was the same. There is a grounding procedure on the ECM port to clear the hard codes, but I may just spend the money and have the dealer do it. Thanks folks!
