SRS Module February 12, 2023, 01:22:46 pm Anyone happen to know where the Air Bag Module is on our rigs? I had the seat out awhile ago and then on our last trip I saw that the air bag light was on. It is throwing a 33 code which is high resistance on the passenger side. Hmmmm... I cleaned and lubed the connections for the pretensioner and tested the resistance of the pretensioner (good as 2.5). I took the seat out again and checked the wiring. It all looks good. Next step is unplugging and plugging the SRS module. Anyhow, I can't find it! Thanks.jorPS. I tried several of the ign on-off sequences to no avail. Also, I always disconnect power before messing with the air bag system.I see a similar size box on the pax side kick panel above the fuel cutoff but it's plastic. I think the SRS is aluminum.

Re: SRS Module Reply #2 – February 12, 2023, 06:12:10 pm I found it under the front seat. I fixed the problem. When I took out the seat I hadn't unplugged the pretensioner and pulled on it pretty hard. The resistance was correct on the pretensioner so I knew it was good. All the wiring looked good. Had to be the plug that connects the wiring to the pretensioner. I bypassed it and success!!!jor 2 Likes

Had to be the plug that connects the wiring to the pretensioner. I bypassed it and success!!!I had a similar problem when the wires on top of the passenger side pre-tensioner plug broke off and caused a code to be set. The pre-tensioner plug is a very tight fit and was bear to remove from the pre-tensioner, only to find that new plugs are not readily available.Using a Dremel tool, the top of the plug was cut away to reveal the small terminals where the wires used to be connected.Soldering very small wires is beyond my tool and skill set, but my friend and fellow Forum member Steve was easily able to solder them. The finished connection was buried in hot glue to add protection to the connection. So far, so good.I'm still looking for a new plug as a spare.Larry 1 Likes
