I have a 92 ls 400 and the trac warning light used to blink now it just stays on Im sure the blinking was code but didnt know how to read it now it just stays on looking for a few answers please help

Same problem with my 1993 LS400 - Trac light stays on. Eventually "check engine light" came on. Took it to my local Lexus dealer. Said I needed new pre-catalytic oxygen sensors, suggested also replacing post-catalytic sensors. I also had a crack in my EGR exhaust pipe. He explained that with bad sensors and bad EGR, the Traction control system will not function properly. I replaced all four sensors and EGR pipe, no problem in two years now. Very hard to replace EGR pipe. Lexus wanted to pull the transmission to replace it but found a mechanic who wedged the transmission out of the way enough to replace the pipe. Dealer said I could drive with both problems just would not get optimal fuel economy. Hope this helps.

Other common problems LS400s have are with time and temperature display "bleaching" out and with speedometer instrument cluster malfunctioning. Had both problems resolved with repair services advertising on Ebay.

Does any awesome Lexus owner knows to remove the POWER HEADREST FOR 93 LS400 so ican install SHEEPSKIN COVERS. Your Tip will be really apprciated.

thanks

I have a 93 LS400 and removed the headrests so I could install new leather aftermarket seat covers. After removing the plastic utility cover on the back of the front seat, peel back the top of the seat cover to visualize the power head rest mechanism. I removed the entire seat cover. Toward the top there are two small diagonal black clips which prevent the head rest post from coming out. Just push the tip of the two clips simultaneously toward the middle of the seat with a pair of screw drivers which will release the headrest post so it can be pulled out. Just push back in when reinstalling.
