'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 doesnt
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 Im 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 youre installing to the Memory Erase Signal (MES)
connector basically grounds a signal wire. If the ground is poor, its
just not happening. Id 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.
