I have a flood car which I purchased from auction some time ago. I have been stumped as to how to proceed with this vehicle. I have replaced the SRS, OPDS, as well as swapped out seats (to check SWS). I have an HDS unit (it is older...which does make me wonder if it can correctly communicate with the SRS which is newer (less than a year old)) which I attempted to use to initialize and calibrate everything. As I walk through the steps to clear and program everything, the system shows that all is well and completes what appears to be the final step (drive the car 22 MPH, put an object of known weight, drive 22 MPH, stop on level ground etc) as soon as it finishes and says its done the code returns. I think there is a possibility that something could be wrong in the wiring harness - but I don't have any schematics to look up (or know where to go to buy schematics so I can check what the voltages should be, make sure there is continuity nothing grounded etc..) - any insights would be appreciated. As a side note I have taken this vehicle to three different mechanics all have given up (and inclusively of one guy who specializes in programming) thank you for taking the time to read and/or respond.

 

I don't know how to edit my original thread so some additional information vehicle is a 2010 TL front wheel drive.

 

There's a link elsewhere in this forum to shop manuals for 4G TLs. I think those should have wiring diagrams in them.

Your post should have an "Edit" button in the lower right row of buttons, although IIRC you might need to have a certain number of posts / karma before that's enabled.

 

Woof. That's far beyond my pay grade.

Here's the thread with the manual. It's pretty comprehensive:

Hello dv -

Based on your recommendation I decided to dig deeper, found the following: Link to Wiring Diagrams for 2010 TL - ill have to dig deeper now that I have to see if I can RCA this bad boy. Thanks!

 

thank you for posting that as well. Ill dig into that thread as well! many thanks!
