I have a 2004 TSX. My SRS (red airbag light) warning light on the dashboard stays on continuously every third time that I start the car. The other 66% of the time it goes off like normal. I recently replaced the driver side HID ballast which required bumper removal. I was very careful and followed the service manual instructions precisely. Could I have damaged a sensor? Is there a simple systems reset that I could perform? Thank you.

 

Check your owner's manual - the restraint system might be under warrantee yet. If so,
let the dealer fix it.

 

Check the warranty section of the OM. The airbag system warranty is different than the bumper to bumper and powertrain. I know its longer, but I don't know the specifics.
