Airbag light, seatbelt control module?

Posted

Edit: whoops. can someone move this to non- powertrain? Thanks

 

Hey all,

 

Ive had this forever, but its been on the backburner. I figure some better minds could help.

 

Airbag light, new clockspring fixed cruise control, no dice on light. Cant figure out how to pull codes for it. Dont know where to go.

 

I looked at a 99? Wiring diagram posted here, showed the ACM hooked to something called a seat belt module. Supposed to be under center seat? Nothings there on mine, or harness, so dont know if was deleted? Mine is a 2001. 
 

Also theres this terminated plug under the air-filter. Dont know where that goes or what it does, any clues on that?

 

Thanks for the help

Dealer is the only way I know to pull those codes to see what is going on. Maybe if someone has a Snap Scan Tool it might do it.

Yeah that was only in the early series of the 24V 2nd Gen. 2001 should be without that seat beat module.

That is ABS speed sensor plug. Double check the driver side to see if there is a wire running up from the wheel bearing. Typically there is a wiring loom near by with a plug for that sensor on the fender skirt right next to the shock tower.

Ah, vehicle has RWAL, so explains plug.

 

I plugged it into a modus or similar a while ago, recalling memory here, tried communicating with Airbag module, and was unsuccessful. Dont know if it was on me, or module dead. Module is plugged in and in proper spot.

 

Any other thoughts for diagnosing it?

So, the seatbelt light comes on and then off at startup, so I believe that indicates functional. But its never beeped at me when the belts arnt buckled..

 

SRS isnt something Id like to backprobe to diagnose.. dont much like the dealer either. I guess if cant figure out, Ill work on getting a better front bumper. :shrug:

There is no chime for seat belts. The light on my truck is just a switch in the driver side buckle. The plug is under the seat. The seat belt module was because the front seat belts are in the front had no way to lock so the module detects g-force and locks the seat belt for prep of an accident. Later series like mine are weight base so when the weight pulls forward then the seat belt locks.
