warning light
I just got this SC 300 and did not receive a manual with it. Recently this warning light has turned on...it is a picture of a car with maybe something to do with the back lights or something to do with the rear end of the car. I checked my back lights and they seem to work. Does anyone know what this warning symbol mean??

That means your rear lights have failed or may fail.
I had that too, and found nothing wrong. However, a couple days later, with that light coming on at intervals, my third brake light bulbs finally burned out. Well, only one of the two burned out.
Seems as if the system checks for conductance of the bulbs and will give you an early warning.

I have a problem very similar. My lil' orange car in the dash is on as well. One of my brake lights is out. After taking apart the lens assembly I find out the bulb and socket is fine, the ground wire is fine, but no power seems to come to the bulb via the wire harness. I do not have a manual (desperatly searching for a lower cost one). Does anyone else have experience with this. Possibly a fuse or a loose connection somewhere in the front of the car?
Its the farthest right bulb of the passenger rear lens assembly for the brake lights.
I swap bulbs, and the bulb works fine in another socket . I get continunity to ground on the socket, but no 12+ when brake is depressed to that socket....again, the others are fine. I traced the wire back to the left side of the fuel tank, and it still has no power. I don't have a manual to track it up to the front of the car.
I have been tempted to hard wire the two brake bulbs together, but have been hesitant. I might tap off a power witre and run a relay from the working bulb, but I doubt this will elliminate the little idiot from appearing on my dash.
Ideas?

Keith,
Has you car ever in an accident? If it is, check the wiring at that part of the car...sometime when they put thing back, the wiring might get pinch.
What about flood, has the car ever got realy wet inside? Check under the carpet of the car. Do you see any rusted parts. That will not have a good grounding and may get the sensor to have a fault signal.
Another thing to check is the brake light sensors. The thing that signal the dash light to be on. I don't know about Toyota and I don't have the manual here with me. But for Honda, the sensors are at the brake light housing. It should be something that connecting the light bulbs and the main suppy. Take it out check for any burnt diote (spelling) or resistors. For Honda, the right side is for the right brake light; the left side is for the left and center brake lights.
I paid ~$90 for the shop manual. Check with Carson Toyota, 800-908-6968 it should be around that price. I can't find a cheaper price than that. And I don't know how to find things on E-Bay plus I rather have the manual now and troble shoot the car.

Without it I am lost. The manual is not that great for some of the repair. Like how to take the power mirror ECU out, one line said take the two nuts out and replace. Yeah, PIA to take the two screws out. Then when I put eveything back, the mirrors work but then my radio stop working and the manual doesn't show where to trace the wiring...

- but did not see any kind of sending unit or what not. Basically wires to wireharness to bulbs. I'll hopefully order the shop manual - Thanks for the #!!!!!!!!!. The thing that gets me is the fact that there is no power to that wire at all when I depress the brakes. Oh, well, I'll re-check the wires for the sensors. Thanks for the input.Keith
P.S. Is there a contact person at Carson Toyota, or do I just ask for anyone in the parts dept?

I'm having the same problem right now, and I have isolated it to a wire coming off the light sensor relay. It has no continuity to the rear stop lights mounted on the hood. (LS400). My question is.... Do I replace the connector, or do I just run and splice a wire in to make it work. Where is the usual failure spot on a harness?

STEVE GANZ e-mail gonzo4u@earthlink.net. He just bought a 97 SC300...I think the brake sensor for SC400 is located in the left side of the trunk, above the jack tools thingy. I'll read it up when I have some time. Right now I have too many other trouble with my car. I can't help you much. Sorry

Tell me more, describe what you did and where is it so I have an idea what you're talking about.
Remember, I only have the manual. Doesn't mean I know how to fix Lexus

seat 1 or 2 buttons: adjust the seat, then push the button next to those buttons and push 1 or 2 at the same time. a beeb sound to let you know it programmed. Do not step on the brake while doing this.
