Back in April I was working out of town for 5 weeks.
I knew the battery would be low but it was dead. Not even the usual red blinking security light on the cluster or radio. I didn't bother trying to start it but instead popped the hood and hooked up a battery charger to the jump posts.
Horn honked weakly at first and cluster/dash lights kept blinking and flickering on and off so I decided it was better to pop the trunk, disconnect the negative cable, and charge the battery overnight that way.
I connected it the next morning and it started like a champ. Radio did its usual CD mech after having no power, clock at 0000 hours, but now I've got "airbag fault" that won't go away after multiple starts.
Disconnected battery and waited a while (I remember there being a sequence to do that before pulling airbag fuses). Then disconnected those fuses. 10 minutes later all connected and no difference. After key on, I get "airbag fault" message.
Anyone have any solutions that worked for them in this case? Please let me know so I can provide helpful hints to dealer technician, it's at the dealer now for other issues.
