Lorenzo816,

I was having a problem with the antilock in my 1990 Ls400. Those DTC I posted previously apply to this car which is not OBD II compliant. My Ls400 now has over 200 Kmiles and still runs smooth and quiet. I also own an Rx300 but do not drive it often.

Check the wires that run along the trunk deck lid arm(hinge) for a broken wire; usually the white or green one. Also, these cars are prone to moisture in the right rear (lower) 1157 bulb. Take it out, clean, use some el lube and replace. Good luck
