I do have an update. About 2 weeks ago, the DSP I had installed stopped talking to my laptop, and after talking to the JL Audio help line, it was determined that I needed to send it in for repair. I removed it, and didn't think anything of it until I drove to the store later and realized there were no faults on my dashboard. My key fob and TPMS worked again. Everything was great for a couple of days, then I drove over some railroad tracks, and the airbag light came on. Key fob and TPMS still work. The problem has to be the wiring under the carpet directly under the driver seat. Seriously, I can bang the carpet with my fist and make the airbag light go off and on. I'm ok with the light, as long as my keyless entry, remote start and TPMS work. I don't want to be without my truck for weeks waiting on a part.
Anyone else with this issue, try pressing on the carpet under the driver seat, that's where my issue is.
