'00 Honda Accord LX, SRS (Air Bag) Light On

Q: The SRS (Air Bag) warning light on my ‘00 Honda Accord LX came on when the passenger side air bag connector was disconnected by mistake and the car was started. I bought the Service connector (Its jumper only) and located yellow MES connector and followed the procedure to read the code and reset it but the SRS doesn’t flash when the ignition is turned on after connecting the jumper on MES. Please see if you can let me know what the problem could be. The SRS light should flash when MES is shorted and the ignition turned on. Do you know what sort of backup power SRS units usually have? Is it a lithium battery, or a bigger capacitor or something else ? I tried to keep the SRS fuse out for 24 hrs but still the problem is present.

A: There is more than one fuse to the air bag system of your vehicle. If I’m not mistaken there are 3 to 4 fuses for the air bag system, it depends on which air bag system the vehicle is equipped with. Pulling the fuses or disconnecting the battery will not cleanse the memory of the air bag computer. Also, you cannot clear codes if there is a hard system fault (meaning something is broken), failed fuse or fuses, or there is a ground problem with the system. The jumper you’re installing to the Memory Erase Signal (MES) connector basically grounds a signal wire. If the ground is poor, it’s just not happening. I’d suggest backing up, check all related fuses and confirm the codes that the computer is reporting. Then confirm that they have been correctly repaired. After which the clearing of the codes may go a little easier.
