TEST AA: RIGHT-SIDE AIR BAG CIRCUIT SHORT TO BATTERY OR IGNITION (DTC B1996)


NOTE: Before proceeding, See AIR BAG SAFETY PRECAUTIONS .


Description


RCM checks right-side air bag module circuit for shorts to battery or ignition by monitoring voltage at RCM harness connector C233, terminals No. 5 (White/Yellow wire) and No. 6 (Brown/Yellow wire). If RCM detects battery or ignition voltage, it will store DTC B1996 in memory and flash Code 37 on AIR BAG warning light.


Possible Causes


A right-side air bag circuit short to battery or ignition voltage could be caused by a short to battery or ignition voltage on White/Yellow wire (circuit 1259), a short to battery or ignition voltage on Brown/Yellow wire
(circuit 1260) or a short to battery or ignition voltage in right-side air bag module.


1. Check for hard or intermittent DTC

Those are the 4 possibilities for your Code 37.

If you are not experienced working on air bags then I wouldn't even consider messing with it - air bags are nothing to fool with.

Remember - air bags hold a charge even after you disconnect the battery - so insure that you know what you are doing before you start touching wires and messing with your air bags!

 

Thank you so much i willl take my truck to the dealership and get it fix now i know what a code 37 is you been a big help.

 

timmyjoe, You better be sitting down when you go to the dealer. 600.00 buck just for harness. The problem is on the pass side front seat the wire under the seat is broken (yellow plug). Need to go out to the junk yard and cut the wire and plug out of another explorer. Leave your self about 6 inchs of wire. Here's the items you will need for the problem, a souldering gun, aicd free soulder and heat shrink tubing. Ok now the fix, undo the battery and cut the wire one(1)inch back from plug strip the wires put on the heat shrink tubing and mach them up, soulder them up, then heat up the tubing and your done. The 6 inchs of wire helps the plug not get riped out of the seat. I did this a year ago and have had no problems. A wrench head at ford told me how to fix it, but ford will not do the fix this way. If you take your time it's a good fix.

 

Thanks dogman that mines 1000$ Canadian dollars about that would have cost me here in Canada i will go to the junk yard and get that harness and fix it myself.Will keep you posted.

Your the man.
Thanks a hole bunch.
