hughes369 Posted September 4, 2004 Share Posted September 4, 2004 This is SNAKE again. My 1992 LS400 is having a Reverse indicator light illuminate everytime the brake pedal is depressed. Why is this? Is this related to the brake light sensor , cause its lit up too. I have checked all those bulbs, and going to try what some of the other posts have suggested on the brake light issue. I also have cleared the airbag light, thanks to the guy with the hands on site. The transmission seems to disconnect from the engine so to speak when the brake is applied, almost a jerk is felt, WTF, is this normal? This LS has about 170000 miles on it. Any help is greatly appreciated. This has been doing this since i bought it with 135000 miles on it. Thanks for any input, The "Snake" magnumpi300@yahoo.com Quote Link to comment Share on other sites More sharing options...
SKperformance Posted September 4, 2004 Share Posted September 4, 2004 the engine is supposed to release from the tranny when the brake is pressed it is called brake release. I would guess you have a wire shorting in the taillight harness.which is causing multiple problems. Quote Link to comment Share on other sites More sharing options...
obergc Posted September 5, 2004 Share Posted September 5, 2004 Sounds like it might possibly be related to the common break in the ground wire that is routed through the left trunk hinge area. You might check the wiring in the trunk hinge area to make sure you don't have a broken wire there. Quote Link to comment Share on other sites More sharing options...
VMF Posted September 5, 2004 Share Posted September 5, 2004 yeah, def the wiring problem in the trunk, search the forum for this issue, there have been couple of threads related to this problem. Quote Link to comment Share on other sites More sharing options...
hughes369 Posted September 5, 2004 Author Share Posted September 5, 2004 I will try these suggestions about the left hinge area. I am hoping you guys are refering to the reverse shift indicator inbetween the tach and speedo having something to do with the wiring in the left hinge area of the trunk? About the transmission jerk i feel, i just think this is way to excessive when it disconnects from the engine. The fact that i notice it is enough for me to write about it. My moms 98 ES300 does not have a transmission like jerk when i apply the brakes on it, why does mine? Thanks for the replys, ill keep checking back for more suggestions or ideas. later, THE SNAKE Quote Link to comment Share on other sites More sharing options...
99lsguy Posted September 6, 2004 Share Posted September 6, 2004 hughes........ Yes, likely the problem is in the harness or pinched elec. wire near the trunk hinge...this has happened more than once here on LOC. On the tranny jerk - have you kept the tranny fluid serviced and clean??? Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted September 7, 2004 Share Posted September 7, 2004 Here is a link to exactly how to fix the broken "white with black stripe" wire in the left trunk hinge. This broken wire also caused the transmission to shift erratically when it broke on my 90 LS - so erratically I almost had the car towed. The broken wire takes only a few minutes to fix. http://us.lexusownersclub.com/forums/index...wtopic=1294&hl= Quote Link to comment Share on other sites More sharing options...
hughes369 Posted September 12, 2004 Author Share Posted September 12, 2004 THanks for all the help. The Snake has fixed the Reverse indicator, it was the broken wire on the left hinge in the trunk. And i also figured out the lower left side brake light, 1157 had a element that looked connected , but had some kind of corrosion or some sh@!@%t growing inside the bulb where the filament attaches to the filament wire stand. So i replaced that bulb, and the warning light on the dash went out for good. Quote Link to comment Share on other sites More sharing options...
