Airbag code 25 in SD crewcab
I recently got this truck ('99.5 F350 CC) and the airbag light is giving me a code 25.
From what I can tell from searching here (and there, and everywhere) this is generally a problem with passenger air bag deactivation (PAD) switch or bulb.
But the Crewcab doesn't have a PAD key switch on the dash. Is there a weight activated PAD in the seat on a truck this old? Someplace else to look?
I hope it's not the 'clock spring'. The local dealer wouldn't give me an approximate cost to diagnose, much less fix. Yikes!
Any suggestions where I could start? In case it's something simple...
Thanks

Really?
That's odd. I've found other posts that discuss the 'fact' that crewcabs don't have the PAD. I certainly don't know where it is, and I do know what they look like. It would be hard to miss. Maybe the manual is for regular and extra cabs, not necessarily the CC.
The reason I've read for no PAD switch in the CC is the CC has plenty of space for kiddie seats in the back, hence no reason to deactivate the pass airbag.
But none of the posts discussed likely reasons for the code 25 in CCs...

I didn't see any special notes for the crew cab trucks, but I could have missed it. If it's true about them not having the switch, they should have their own wiring diagram that that shows the wiring without the switch.
One thing I did notice is I had a choice of what truck I wanted to look at. Either a f250-350, or a superduty. You called yours a superduty, so that's what I picked, but I am not too sure what the difference is. The later diagrams only have "superduty".

hmm
You know, seems I read somewhere the early trucks of this style weren't called "Super Duty". Mine is a 5/99 build, considerred a "late" '99. It is an F350, but maybe not technically called Super Duty...
Thanks for the input!

How friendly is your local dealership? The shop guys at mine don't seem to mind giving advice.

Crew cab should not have a PAD switch. Has this been in a collision and the module replaced? If so then it may not have been reconfigured for your truck by the body shop. Happens alot. It would need to have the vehicle "as built" data programmed into the module at your local dealer. Otherwise I would suspect a faulty ECS now called the RCM. It thinks a PAD switch should be in place and thinks the switch has failed.
1999 was the last year for the light body F250 and the first year for the Super Duty body style mid year production. The one in your avatar is the Super Duty.

Thanks for the response.
I can see the dr fender and hood have been off, and dr mirror replaced. So, yes, it likely has been in a wreck before I got it. This could be the problem.
Sounds like a trip to the dealer, and a few Benjamins will take care of it.

B1859 fault code
Just had the truck at local dealer. Got codes B1869, B1871 and B1890. First is a 'hard code' calling for replacment of ECS. The next two are odd because I have no PAD.
But I am curious about HomerWinzlow's comments about programming a module (you there HW?). Since I don't have any history of the truck I don't know which, if any, modules have been replaced.
Do you still think a module needs to be 'reconfigured'? Which module would be programmable with the 'as-built' data? The dealer here said the ECS can't be re-programmed.
Any advice on procedure to replacing the ECS, or am I best to leave this to the dealer? Is there a risk of deploying the bags?
Thanks

Airbag code 25 - Resolved
Just to follow up here in case someone finds the old post.
Someone had installed a PAD switch behind the dash in my crewcab. (no hole in the dash)
Once the switch was removed, codes cleared, all is well.
