You may need to visit the dealer for this. Given the history of working with the dash assembly, the typical cause is the ignition switch was turned on while the air bag was disconnected The Air Bag Computer would detect that, set the diagnostic fault code, and turn the warning light on to tell you. You can try removing the TWO air bag system fuses for a few minutes, but on most cars the fault codes in Air Bag Computers can not be erased that way. Codes can be erased in other computers by disconnecting the battery for a minute, but I hate to recommend doing that because a lot of computers now are designed to lock up or lose their programming when you do that, necessitating an expensive trip to the dealer.

The fuses will be in yellow handles making them easy to pull out. If the codes will not erase by pulling the fuses, you'll need to find a mechanic with a scanner that can access the Air Bag Computer to erase the codes. If there is o other problem, the warning light will turn off. If it comes back on, be sure to record the fault code number(s) so we can figure out what to look for next.

You can ask at some local auto parts stores too for help. The people at many of them will read fault codes for you for free, but most of the time they can only read codes in the Engine Computer, and most of the time they just have simple code readers. You usually need a full scanner to erase fault codes.

On the GM Vechiles when a fault is found on each key cycle the air bag light will flash 7 times if there is a fault in the air bag system the light will stay on solid. If there is no fault on that key cycle the light goes out

Thanks SATURNTECH9. When the problem is gone, can the code be erased without a scanner?

No but after so many key cycles the code would clear on it's own.

Thanks for guiding and your urgent response, normally I obuseverd the air bag self checking system will blink 3 time and then goes back if the system is healthy.
Dear CARADIODOC you are right during fixing the dashboard I was also conforming the healthiness of all equipment that all are working perfectly. And I connect the airbag connector in last when I finish all the activity. May be it's because of that. I also disconnect the bettry for 3 to 4 hours for auto reseting the system. But it's fail.
It's code 71.
What you would advice me.

SATURNTECH9 said the fault code should erase and the warning light should go off on its own after you restart the engine enough times. Beyond that, if disconnecting the battery didn't do it, you'll need to find a mechanic with a scanner that can access the Air Bag Computer to erase the code.

You can try erasing the code but I think there is still a problem.
