Hi all,
Car started throwing a trac/abs/vsc error with a check tire system icon.
It's on my 2005 ls.
Fired up techsteam and no communications to that module.
The wiring diagram is a bit unclear but is it the trac ecu thats attached/inside to the abs module?
I think the earlier cars had the ecu inside the car but want to check before I go probing biases/power etc.

 

On a 02 model the skid control ecu is located undernearh the dash, drivers left knee. Also a abs/skid control control fuse located drivers kick panel
