Air Bag Code Issue
Hello All, I've not been on in a while. But just this week killed my 97 EB Expy battery. My fault, not a problem. After charging, I now have an Air Bag Code 52. I found through searching that this code may clear itself after several key cycles. Am I understanding this correctly? Has anyone had this same experience? Thanks for any and all help.

I would take it to Autozone or a mechanic friend and have them clear it with their scan tool. Its possible you actually may even have an issue, but if your not experiencing any problems, then just ask one of them to clear it.

Thank you High_Horse and alloro. I was thinking it was as simple as "Got it cause Battery died and I, less than wisely, tried to start it shortly after connecting the charger, would take about a half dozen key cycles or so to clear". However, after much research, I read that it takes 256 key cycles to clear a fault that no longer exists. Does this sound right? Also, Reading the link posted, it seems that you jumper the diagnostic pins with the key on, which created other codes, then remove jumper and cycle key. Does this sound right, or am I missing something? I don't want to fry something that may be otherwise OK.

1. Cycle the ignition switch to OFF and then to RUN.
2. Wait for the trouble code to flashing completely one time.
3. Use a jumper wire to short the 2-wire diagnostic connector. (This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.)
4. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).
5. Remove the jumper wire. (This jumper wire must be released within 25 seconds after the diagnostic monitor tone sounds.)
The trouble code should now be cleared from NVRAM. The next highest priority diagnostic trouble code stored in NVRAM (if one exists) will begin flashing.

You have only two choices:
1) 255 key cycles without a fault
2) Use an appropriate scan tool to perform the reset. The Rotunda NGS and the Snap-On Solus are examples of several scan tools that will work.

ProjectSHO89, I had seen elsewhere another "jumper trick" that involved two pins in the Data Link Connector, One was identified as "Air Bag Reset" pin, the other "Ground". The specific locations in the connector were given, however, I did not write them down. Would this also be incorrect advice for this vehicle?
Thanks all for the help. Seems I am destined to find someone with a scan tool. Knowing the dealer in this area, this issue would be an open invitation to "must replace air bag module, and more". They are not very busy and will try to be helpful and find things that need attention, meaning more business. Again, thanks for the help!
