Forgot to disconnect battery before unplugging wire harness under seat....tried to clear code but comes back immediately. Locking device on harness cracked but it's cinched tight with a tie wire ,and everything else works on car but just a warning light.....wondering how to test.02 v70xc 2.4t........

 

Use your compatible scan tool to find out what the SRS system thinks is wrong.

 

Yeah ...if I had one I wouldn't be here asking what to test for.

 

Or how to test I should say.

 

Or how to test I should say....i. looking for a more advanced reply like a wiring diagram to show me power to test continuity or voltage coming in .

 

Sorry but a compatible scan tool will give you a clue to use for the answer. Anything else will be a guess. You can find a wiring diagram at volvodiag.com. They don't go back to 2002 but the diagrams will be somewhat similar -

 

I don't have a scan tool!

 

If you don't have a scan tool - how are you trying to clear the code?

The only way to clear a SRS code - is with a compatible scan tool. No other method will work.

 

I do not own a scan tool.a garage with one did it for me .....

 

What code/s keeps coming back?

 

Went back to shop.....0D00 left ( driver) seat buckle signal missing resistance too high....pulled seat, measured continuity ...so far that checked out but one wire I couldn't get a Reading on .guess it could be the buckle itself but either way I have to find the culprit and so far my continuity test hasn't solved it.I am told through readings it won't keep air ags from being deployed? Gotta fix it either way!

 

 

That's what I hear..... So question is can a scanner w SRS do this or only vids/ dice?

 

There are many compatible scan tools that can talk to the CEM other than VIDA/dice.

A compatible scan tool is able to read and erase codes from all the modules in the car (if installed, you probably don't have a RTI road traffic info module or PHone Module, as well as a couple of others)

 

Yeah only thing I am weary about is " permanent fault" ....guess we'll see when I get someone to clear the CEM
