Dash Light On - Corolland: the Toyota Corolla Forums

Bikeman982

I changed the blue covered white lights behind the instrument cluster because they were burnt out and now the "airbag" light stays on.

Did I do something wrong?

What causes it to stay on and what should I do to get it fixed (besides taking out the bulb)?

Sounds like one of the airbag sensors is bad or not making a good connection (same thing happens when you discharge an airbag - the lamp stays ON). If it is pre-OBDII (1995 and older in most cases) - you should be able to query the airbag diagnostics, if OBDII (1996+) should be able to put a scanner on it and find out what the deal is.

I usually check http://www.troublecodes.net/Toyota/ for pre-OBDII procedures and http://www.obd-codes.com/ for the OBDII compliant DTCs.

Could it be that I did something when I took out the instrument cluster and changed the four bulbs?

I don't think I did anything to the airbag sensor at all.

It was working as normal, prior to me changing the bulbs.

I will check the manual and try to use the CEL code by jumpering the terminal connections on the diagnostic plug.

If it says the sensor is bad, is that on the airbag in the steering wheel, or at the unit in the center console?

It is on my wife's 1993 (OBD-I).

I have not re-checked the wife's car yet to find the cause of the "airbag" light staying on.

Anyone know what could have happened when I changed bulbs on the instrument cluster to cause it to come on?

when you had the cluster out, did you have the ignition on? if so, there is your problem. the airbag ecu looks to see if the cluster is there. (i think just for bulb check purposes)

if that is the case, it just needs reset. when i bought my 93 corolla, the speedo connector was unplugged. when i plugged it back in, the airbag light was on. cant remember what the code was, but i reset it, and all ok since.

I did have the ignition on - to test the lights I had changed.

I will reset it and see if it comes back - thanks.

I disconnected the battery and then re-connected it. The light is still staying on and I wonder if something else is wrong?

I have to get the car CA emission tested and I am sure it will not pass the visual inspection with the light on.

I have to get it fixed before then.
