Lexus SC430 :: 2002 - VSC Engages At Slow Speeds
Jan 8, 2013
My SC430 '02 has developed a problem with the VSC. Unfortunately it s not the light but the VSC engages at slow speeds. If I accelerate from low speeds, engine does not rev up and the VSC lights comes on. It works as if I was skidding and tries to correct the direction of the car. Just as it should if I was on ice or experienced aquaplaning, but I am on a dry road. I did a reset of the ECU, had the car at Lexus (they were able to duplicate my issue) for a zero-calibration. They found no problem with the sensors. All did not work. Presently I drive with the VSC disengaged. I do suspect the speed sensors to act up as I had Tein-Coilovers installed, but how can I get to the source of the problem?

When braking at very slow speeds(less than 5 mph), my ABS system engages. It can be startling and the truck keeps rolling forward unless I pump the brakes to get it to stop. The truck is drivable, I just have to be careful when pulling into our garage or slowing behind someone at a traffic stop. What could be causing this?

I have an 02 Jetta 1.8t automatic with about 140k miles. It has always been a great car. Last week, I was taking off from being stopped at a light and I heard a loud beep and saw that my oil pressure warning light was blinking! It blinked 3 times and then was gone, now last week temperatures were very low for my area. Today was actually pretty warm and sunny. I was stuck in gridlock traffic, it took me 25 minutes to go 1/4 mile. Idle, Idle, creep forward... Idle, Idle, creep forward...etc.
I noticed that the temp gauge read over 200, not in the red, but too close for my liking. Then a moment later when it was time for me to move up a bit, there was a beep and then that low oil pressure light again, 3 blinks and gone. I was panicked. I shut my engine off while I waited for traffic to move and when I would move forward it was the same thing. I finally pulled over, as I was stuck in traffic about 1000 feet from a friends house. I stayed there for 4 hours and then decided to fire her up again. Totally normal.
40 Minutes later as I rolled into my driveway, boom there was that light blink again... I am really concerned but confused by the light not staying on continuously and not having the check engine or any other warning light ever come on. It's weird to me that when this happens I am either taking off or coming to a stop, never going more than 5mph.

2002 Ford Escape XLS 5 Speed, My timing belt was just replaced along with the timing idler pulley, timing belt tensioner, serpentine belt, tensioner and idler pulley, spark plugs, and valve cover gasket. It drove great yesterday but this morning when I was taking my son to school the engine started knocking. It does this idling and at slow speeds. Once driving the noise disappears. What this may be?

My truck has grinding noises when i am making turns from a stop or at slow speeds. Also my 4x4 dash light keeps flashing several times both when I am sitting still and when driving. Neither my 4x4 auto or 4x4 high work but the low will work. Trying to pinpoint where I should look to fix them. I did replace the 4x4 control mod as an attempt to fix this.

I am having an issue with the car not feeling stable on the highway or at speeds over 50mph when I am on a curve and go over a roadwork patch. The cabin of the car seems to float way too much to the side, almost like hydroplaining although the wheels stay put on the road.
After describing this to a mechanic, he said it sounds like my lower control arm bushings are gone. He looked at them and confirmed it, the rubber bushings that control the side to side action are cracked and worn out. He said that he is unable to just replace the bushing and has to special order the whole arm from the dealer (approx 200$ each arm).
I went to get a second opinion and another mechanic basically told me the same thing except the price on the part went down to 175 per arm with 2-3 hours labor.

I test drove the sc 430 the other day, I found it very smooth and very soft ride. I noticed that when I accelerate the car feels heavy as if it lacks the torque. Is this normal?
Also, the steering felt loose at high speeds above 60mph. Is this normal?

I replaced my rear brake pads this weekend. I used oem pads and used the shims with CRC lubricant. I also compressed the brake calipers and made room for the new pads. I also tried to take off one of the rotors but it would not come off even with putting screws in the rotor.
Everything seemed fine and brakes were strong but when I went for a test drove there is a clicking sound at low to medium speeds come from the rear passenger side. I checked the retainer pins and they are on correctly.
What the problem may be? I would like to spin the wheel but the parking brake is on. Is it okay to take off the parking brake while jacked up if I block the wheels??

Dropped my car off at the shop due to the transmission lag from stop to slow speeds. Sometimes it feels like I was dragging sandbags. Then all of a sudden the car wakes up and goes.
The shop said the fluid "looks" fine but seems to think there might be too much fluid in it. So here we go with a transmission service. I hope this fixes it.

I have a 2010 LS460 AWD with 42k miles and notice when I am making a medium to wide angle turn at parking lot speeds the front wheels make an intermittent metallic clicking/ticking noise that can be clearly heard when the windows are down and stereo is off. The noise can be heard when turning in either direction, driving forward or in reverse, and both accelerating and slowing down. Doesn't seem to happen when I'm turning the steering wheel while the car is stationary. Dealer suspects noise is due to dry contact areas between pads, calipers, and anti rattle springs and wants to perform a brake service for $330 before they're willing to investigate further (car still under warranty till end of the year). If noise is brake-related shouldn't it only occur when I'm applying the brakes? What should I do?

I have a 2001 Ranger XLT 4x4 with 38,000 miles. When I am at very low speeds (like 5 mph) and usually pulling into a parking spot, the ABS kicks on. I've heard it's the "hub" in my wheel but the dealer won't know which one to replace. Dealer said, take your hands off the wheel and see which way the truck pulls when the ABS is kicking on....well at 5 mph it doesn't pull. At $300 just for the part, I need to know which wheel it is!
Also a friend of mine had this happen to his Chevy Silverado and the replacement hub broke again so they just turned off the ABS....Is this OK to do if I don't want to fix this problem?

just bought a 2002 lexus sc430 the car is nice but i have been reading in regards to the throttle lag. Any resolution for this. I've read that the apexi or blitz trottle control is an option to work with the lag.

I have 2002 SC430 with an annoying vibration through the seat/chassis at 60mph but she's smooth at 55 and slower and at 65+ mph ? Things I have tried so far ...
wheel balance
wheel alignment
2 rims rerolled that were out of round
bushes and suspension all checked
moved wheel positions front to back etc
Thinking now maybe driveshaft or uni joints ? or new tires but that's an expensive exercise !!

My check engine light came on.. so I took it to express tires.. And they said that they need to replace my vacuum hoses cause it busted ... well when I saw the guy used the obd checker thing.. after checking the codes.. i saw that when u turned on the engine.. the vsc on and vcs off lights came on..
So I figured after he fixed the problem.. it will go off.. well after he got done.. fixing the problem.. I drove away.. after bout like 2min.. i had to turn around cause the vsc on and vsc off came on.. and I told the guy to check.. And he used his checker.. and there was no problem.. and the "check engine" light is not on anymore.. just the vsc on and vsc off!!
Could the checker.. messed it up??? the vsc off button.. only works when the key is turned on.. " not when the engine started but right before it.. when the power comes on" so the button is working correctly.. it just comes on.. when i start driving the car...
And no they did not check my tire pressure or do anything to the tires or the wheels.. it just turned on.. when he inserted the obd thing to check..
And yes I read the [URL] .....
Is it dangerous to be driving with the vsc and vsc off light on??

I recently got into my 2002 SC430 and could not shift the car out of park. In addition, another symptom was that when I pressed the brake pedal, my rear brake lights would either come on momentarily and then turn off (looked like a strobe-light effect), OR the rear brake lights would not come on at all (the taillights, however, continued to function).
The only way to get around this issue was to use the manual override (by taking out the little plastic tab on the shifter and using a screw driver to press the hidden button, which would momentarily override and let me shift).
After much research, I found out that my Brake Switch/Sensor was failing (this is what tells the car's computer that you're pressing the brake pedal, and thus allowing you to shift out of Park). Unfortunately, I don't have the model number handy.
My non-Lexus mechanic charged me $100 (parts and labor) to replace the Brake Switch/Sensor. I'm not sure how much the actual part cost, but it couldn't have been much. It's a very scary feeling when you need to drive somewhere quick and you cannot shift out of Park.

I had to replace the ECU on my 2002 sc430. Although the original ECU was malfunctioningthe car started and was drivable (but the speedometer and odometer did not work, nor did the power steering). Following installing a used ECU, the car will now not start. I reset the ECU following the directions posted by others in this forum (both the gas pedal method and removing the fuses), but that has not fixed the problem. Do I need to have the dealer sync the key to the new ECU?

I have a 2002 SC 430 with 68,000 miles on it. Having problems with the transmission? Today, I could not go forward in any gear...could go in reverse. I turned off the ignition and re-started the engine, then the car worked fine.
Tonight I went out and the car was fine. However, later had the same problem.
