Replaced heater core and now my airbag light is on... (Disconnected most electronics, mostly removed dash, removed steering column completely).
I removed my battery completely before starting the job.
I checked the onboard engine codes doing the 'On-off-on-off-on" check. There were no errors.
I checked the instrument control panel errors by doing the "odometer reset-On-release odometer reset" check and there were no errors.
I reset the ECD by touching the positive battery terminal to the disconnected negative battery terminal for 30 seconds, then I hooked up the battery, Ignition switch 'On', Headlights 'On', Headlights 'Off', Ignition 'Off'.
Passenger side airbag connection appears to be good. The clockspring connections appear to be good and all other steering column connections appear to be good.
Airbag light still on.
Maybe I need to go to an autoparts store and have them check the codes with a code scanner?
