Hi all---newbie here so I hope I'm doing this right.
I have lots of electrical problems with my 1999 S80 T6. I purchased it about 4-5 years ago (85000 miles) after the 4 hurricanes hit Florida during 6 weeks. I think this was Florida car--therefore a flood car. I would like to locate all the computers I can get to, especially the ABS, to inspect and clean the contacts and connectors and see if that helps.

current failure lights:
STS, ABS, the triangle with skid marks, check engine, brake

current messages:
Brake failure stop safely ASAP, transmission service urgent, power steering service req, and several others intermittantly.

Idle goes up and down when warm, sometimes lurching foward while in gear and eventually stalling out. Runs great as long as foot is on the accelerator.

All fluid levels are good. Tranny does have a sticking or non-operating valve preventing it from going into 4th gear--told would be $3000 for rebuild. Brought it to dealer for Brake Failure message--was told front wheel speed sensors--replaced them (cost of about $150 each)---OOPS--wasn't the problem--that's when I stopped them from replacing modules.--Car stops fine--and the odometer stays at 194000 miles for 2 years now!!!!
Any help locating the computers would be appreciated!!
Thanks in advance--and keep up the great work!! Forums like these should exist for everything!!!

 

 

Thanks poopbunny---from that diagram--is the module under the driver's seat the ABS module?

 

4/9 is SRS . But that's under the center console.
The only thing under seat is amplifier or 4/52 PSM (Power Seat Module)
ABS module 4/16 is inside engine compartment beneath fuses, directly connected below ABS pump.

 

alot of those warning lights together most likely could mean a faulty ABS module, theres a website that can rebuild the ABS module for around $120 (shop would charge round $800)

 

Hey Viper---can I use the car while the ABS unit is out getting rebuilt?? Since it looks like it doesn't do much now anyways--except give me messages. I mean is the car drivable without the ABS??

 

It will drive, but not right.

Car will feel like it has a lot of torque, also consume a lot of fuel and cause a lot of other faulty codes to show up which will have to be erased.

The T6 likely came with DSTC ABS which will be difficult to repair/rebuild, if not, impossible.

 

Yep its still drivable...i havent experienced any issues driving mine without the abs module other then all the warning lights.

@poopbunny: i actually just found that out, its really dissapointing, one website said it wasnt repairable. The other one said it was, so we will see.
