Air Bag Cautions

Jan. 1, 2020
A Honda Civic's airbag light came on after power steering rack and pinion was replaced
Dear TroubleshootersDear Troubleshooters:
I have a 1995 Honda Civic four-door in my shop. The power steering rack and pinion was replaced two weeks ago. The battery was disconnected while the rack was replaced. Three days later the airbag light came on and stayed on. 
I disconnected the battery and the fuse and then reconnected them. The light is still on. Is there any way of pulling out the codes or resetting the light, without expensive diagnostic equipment?
I checked the battery, and it’s good. Would replacing the rack make the light come on a few days later? Is it related? Please let me know.
Thank you, 
Allen (via e-mail)


Dear Allen:
Airbag codes can be retrieved by connecting the SCS service connector to the service check connector as shown in the graphic. The SRS lamp will blink a two-digit code for a malfunction. If the system is normal, the lamp will display continuous short blinks. Repair any codes present.
Could the malfunction be related to the rack and pinion replacement? The answer is an emphatic yes. When the lower steering joint is disconnected during rack replacement, the steering shaft can turn, which will affect alignment of the airbag clockspring. If the clockspring is not properly realigned before installation, the wiring will be stressed and codes for opens and excessive resistance can result.The proper procedure for aligning the clockspring (Honda calls it a cable reel) is as follows:
1. Be sure the wheels are facing straight ahead.
2. Rotate the steering shaft clockwise until it stops.
3. Rotate counterclockwise approximately two turns until the yellow gear tooth lines up with the mark on the cover.
4. The arrow mark on the clockspring should point straight up.
5. Reassemble steering shaft.
