Im trying to get my sc400 emission tested on the dyno but he said he cant turn the TRAC control off? is there a way i can turn it off with out the button because the button does not work? iv heard that you could possibly remove the TRAC relays is that correct? Also the TRAC,ABS, and TRAC OFF lights are on all the time when i go over like 30mph and only cut off when i turn the car off? could this be the problem or does this mean something else?

Please help if you can

Thanks Again

It sounds like two issues.

Doesn't the sub-TPS control TRAC? This is the specifications for your throttle position sensor settings:
Main TPS .40 mm .65 mm
Sub TPS .30 mm .50 mm

There was apparently a recall in 1992 because of continual pad drag due to unreleased pressure in the rear lines. I doubt you could get the dealer to do anything at this point. What year is your SC400?

Look at this old thread https://www.clublexus.com/forums/sc-...n-control.html It sounds like you can pull the fuse or relay and solve your immediate problem.
