Hi everyone,

the SRS light has been flashing for years now. I remember at some point I had a code related to the driver's seatbelt.
I bought the Tachyon software and BT OBDII adapter from ebay, and just checked the codes.

There are no codes anywhere, not in engine, not in A/C, not in SRS, nothing.

I had the dealer replace timing belts and the water pump, and I asked them to diagnose the SRS.

They said the ECU is bad, and it'll cost me $1k to replace.

Any idea what could be wrong? The tachyon software does have a reset button, but I don't think it worked since there are no codes.

Any ideas what I can do to reset/fix the SRS light?

If I do get a new ECU, is it's a simple replace procedure? What about the keys/remotes etc?

Thanks!

 

I shortened TC and GC pins in DLC plug, and the SRS light blinked a 72 code.

This points to code B0138/72, shown here:

What does it mean? the seatbelt pretensioner might be bad?

I've been reading that it might be a plug under the seat got loose, is it related? Do I just unbolt the seat and check the plugs?

Thanks!
