problem details
Air Bag light came on then check engine, traction control, etc... All door locks cycled on and off. Engine started to stall. Dealership stated that there where no codes and they could not recreate the problem. Drove the truck for two days with no problems. The third day I started the truck and the airbag light came on and the gear indicator stayed in park when the vehicle was in drive. Turned the truck off and then back on and the light when away and the gear indicator worked properly.
The ABS light was staying on the would turn off, now it's staying on again and the truck is "running ruff"
abs and ebrake light on. ebrake sporadic
