Well, my car is a 94 LS400.

The problem is the trac light came on, and I thought nothing off it because it dissapeared the next day. Now about 3 days later the car starts acting up. I start the car and tap the brake and the "R" light in the dashboard comes on. I turn off the car and start again, still comes on. As I drove, I noticed that whenever I hit brakes the "R" light in the dahsboard came on and a jerky movement followed. I am thinking somthing is wrong with the transmission, but I have no idea. I have an appointment with Lexus on Friday so if anybody could help I would greatly appreicate it.

 

Check out the wiring that is in the left hinge of the trunk. One of these wires (I don't remember the color) is apparently too short and tends to break apart. When this happens, all kinds of weird things occur.

When this happened in my LS (93 model), the remote trunk release would not work, the R on the transmission gear indicator in the dash flashed when I pushed the brake, and the brakes felt strange.

 

I wil check it out thanks.
