A question about SRS

[Wilson]

I currently have three airbag codes (it was four previously) and they all say that there is a short in the ground. The short in the ground affects the driver airbag, passenger airbag and both seat belt pretensioner. I followed the service manual to the best of my ability through the inspection process but now I’m stuck. I know all electrical systems must have a ground in order to function properly. Right now, I don’t know if the wires went bad or something. I am stuck.

Could you post any codes you got stating with first to last.

Initial scan before the inspection process:
B0102
B0107
B0132
B0137

After the inspection process and current:
B0102
B0132
B0137

Not sure what vehicle we are on? According to this code b0102 something is grounded
that should not be. Which is labeled short to ground. could be the device or wiring.
All the codes you have are for short. I usually go with the first or second code due to
other codes will cause other codes.

The vehicle in question is a 02 4Runner.

How can I check to see where the ground is occuring?
I have a multimeter and the closest setting to satisfy the resistance is 2M. And when I was checking the resistance to body ground, while it was plugged to the module, I was picking up .65.

I thought the link I posted in the above would help.

UPDATE: I just received some new information regarding the airbag code. My mother just told me that the day the light came on was when she had to honk at someone to get them to move. She normally doesn’t sound the horn so when she sound the horn today, she remembered everything. I’m wondering if this new information can narrow down the likely source to the code.
