My airbag light came on suddenly, next my overdrive light started flashing off and on, my speedometer stopped working and my check engine light came on. I heard beeping from the computer on the passenger side wall. I am getting power to the a/c blower and airbag off light on the dash when the key is off. Also my key less entry does not work like it should since this started. I took the negative battery terminal off to reset the computer, my speedometer works now, the overdrive light went off, and the check engine light went off, but the airbag light is still on.
