Have Toyota Questions? Ask a Mechanic for Answers ASAP
Sure,That's fine.You don't have to accept an answer on JA until you are satisfied with it.Your question was "Will the air bag work with code 41" and the answer is NO.The air bag system goes disabled whenever the light is lit.If you want to know how to troubleshoot the air bag circuit using the snap on scanner you should close this question and re-open the question you really want to ask.You should also post everything you have tried and let the experts know that you are qualified to work on the Toyota air bag system.If you are not,it will explode or you may cause more damage than repair.
If the ignition switch is left in the ACC or On position while servicing the battery. This can cause the diagnostic system not to function correctly, causing a code #41 to be set. In both cases the Air Bag warning light will be on. The first step would be to check and record any codes that the Air Bag computer has in memory. The factory procedure for clearing the Air Bag computer of codes is simply disconnecting the battery ground cable for 10 seconds. Be sure the ignition is in the off/locked position! When the battery is reconnected and the ignition switch is turned on the Air Bag computer will run a system test. If all tests pass, the warning light will go out. If not the warning light will stay on. If there is a code #41 stored in the Air Bag computer it cannot be cleared by disconnecting the battery. To remove this code requires a special procedure that I will leave to another expert to answer since you don't want to accept this answer.Good Luck.
AllData does not have the procedure for clearing code 41.Neither does Mitchell on demand or any diagnostic tool that you posess.This info is guarded by artesian ninja monks . LOL!Is that what you want to do?Clear that code from the center airbag module? Here is how to proceed.When I say service wires I just mean jumper leads.
To clear code 41:
a. Connect the service wires (Jumpers)to terminals Tc and AB of the check connector (diagnostic block under hood) b. Turn the ignition switch ACC or ON and wait approx. 6 seconds c. Starting with the Tc terminal, apply body ground alternately to terminal Tc and terminal AB twice each in cycles of 1.0 +/- 0.5 seconds. Finally, keep applying body ground to terminal Tc. HINT: When alternating between body ground of terminals Tc and AB, simultaneously release one from body ground while applying it (body ground) to the other terminal. If the time interval in between is too long, code 41 will not be cleared. d. After several seconds, when the airbag warning light starts to blink on a 64 m second cycle, cancellation is complete. HINT: This method clears not only code 41, but also other malfunction codes all at once. Use this method only when the repair procedure is completed. That will do it.Air bag back in service and light out.
