04 Fleetwood Jamboree E450 chassis v-10 airbag issues

[restless1]

I have a 2004 Ford V-10 Fleetwood Jamboree GT Class C. After I start the motor the airbag light cycles through its test then stays lit. My mechanic ran the diagnostic and found the module under the driver seat was faulty. Replaced that module with a used, known to be good, module, ran another diagnostic and no codes were received, but the light continued to stay on as before. Strange. Anyone have any ideas what should be checked now? I've already spent $900.00 (but no money has been paid. The mechanic is researching this and will fix it before payment is surrendered). Good mechanic!

You are correct sir, I apologize. It is an E450. Thank you for that.

Are you sure it is a F450 chassis and not an E450 chassis ?

I checked the wiring diagram on the E450 (99% sure that is the correct chassis) and the warning light is wired directly to the Safety Restraint System module. Assuming no issues with the wiring, the only thing that can turn that light on is that module.

Well, the recall check came up empty. The report said 0 open recalls.

Thanks! I'll see if I can find that recall.

There were so many issues/recalls concerning the Takata Air Bags, you may want to verify that this one isn't part of that group. I assume you can check via VIN number.
