Flashing Airbag Light Q. Hi Vincent, I have searched through your Q & A area, But didn't find my answer. I have a 1995 Ford Mustang GT 5.0 H/O Convertible. Recently I had to replace the ignition switch and linkage within the steering column. Boy, what a job. In the interim of this mess, I did something I later found to be real dumb, Not to mention dangerous.

I removed the horn cover and disconnected the airbag to remove the steering wheel. Never did disconnect the battery! Anyway, I repaired/replaced the linkage and ignition. Everything back together, reconnected the airbag {battery still connected} started the vehicle. Okey Dokey. Ready to pat my self on the back, I noticed the AIRBAG light blinking in code.

I have checked the wiring to the SRS console and the tape wire in the steering wheel checks good too. When I turn the ignition on I get 72 code about six times and then the light remains on. Prior to my great job, all was well. Any idea what the heck I did??? I sure hate to have to go back to Ford after saving about $400.00 on the ignition and linkage. I can see the Service Manager grin in my dreams.

Thanks for any help you may have.

A. Okay, the code 72 means; "Hey!!! You did something stupid and dangerous and I'm not going to let you forget it". Ford has a code for everything.

Actually a DTC 72 indicates that high resistance in the driver side air bag circuit existed at one time, but no longer exists due to an intermittent condition, or a repair made to the circuit. In other words it detected that you unplugged the airbag and plugged it back in. Now I suppose you want me to tell you how to clear the code and get that grinning Service Manager out of your dreams. Personally I dream about Jeri Ryan, but to each his own.

Okay, here's how to clear the code:

1. Follow the diagnostic procedures to service the fault condition flashing on the air bag indicator.
2. Cycle the ignition switch to OFF and then to RUN.
3. Observe air bag indicator prove-out (six +/-two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.
4. Locate the Diagnostic Service Connector located underneath the glove compartment containing Circuits 631 (T/R) and 57 (BK).
5. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground.
6. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).
7. Release short on Circuit 631 (T/R) to Circuit 57 (BK).
