Lexus SC430 :: Engine / VSC Light Came On
Sep 4, 2013
So I went on a little trip about 500 km away.. when i got there everything was normal.. next day while hanging with my buddies my Engine light, VSC and VSC OFF light came on.. I wasn't pushing the car or anything, driving normal and going around 120 to 135 kph on hwy there. Usually people would panic but in the past I have had cars that got these lights and usually its just a sensor.
I mean the car drives perfectly normal, i have driven it 900 km after the light, the temperature doesn't rise, there is no leaks anywhere, there is no smell, engine oil is all there, everything seems perfectly fine. I read a few threads referring to the oxygen sensor? I am thinking of getting that replaced.. how many are there that I would have to change? Also someone mentioned ABS sensor in another thread.. not sure what that has to do with the engine, i mean ABS has its own light right?

My check engine light just turned on recently. Just hit 115K miles on my SC430 a few weeks ago. Is there a service that I'm missing? Running absolutely fine, oil change recently as well.

I have a 2003 SC430 with 170,000 miles on the odo. When at idle, the car shakes a little. I notice it the most when at a red light. But if I put the car in N, the shaking goes away. It happens with the most severity when in D and with my foot on the brake. I'm assuming the shake is normal for a car of this age and mileage, but i'd like to eliminate it.

About month ago, the CHECK ENGINE, VSC, and VSC OFF lights came on in the dash of my '03 SC430 (~175k miles). Took it to the dealer and they read the codes; indicating a bad O2 sensor. They replaced it, and the lights went off. A few days later, the lights came back on. The lights remained ON until this past weekend.
On Sunday, i went to start the car in the morning and the thing wouldn't turn over. Turns out the battery was dead. The label indicated it was 5yrs old. So i bought a new battery. After installation, i noticed the error lights were no longer illuminated on the dash, but just figured it was due to the fact that the battery was disconnected during installation. But after driving it extensively since then, the lights have remained off.
Something else i've noticed since installing the new battery is the lack of the "rotten egg" smell from the exhaust. Before the change, i noticed a significant decrease in acceleration and the emissions smelled very bad. But for the past few days, i've noticed a dramatic increase in power and cleaner smelling emissions. Not sure if they're related...
Could the check engine lights have been the result of my battery dying? I'm not sure why they haven't come back on since the battery replacement. Nor a reason why i'm noticing improved performance and better smelling emissions.

I have a o3 sc430 that's driving me crazy I have replaced the 02 sensor on my car three times and the cars vsc and check engine light comes back on after driving less then a mile. If I really step on the gas it'll come on faster. Where should I look for a vacuum leak? The mechanic says it could be electrical problems too...

How do I fix a brake light that is out on a 2006 sc in the tail light on the passenger side?
Can these be repaired or do I have to change the entire light?

My stock DRL/high beam lights officially died this weekend on my 06+ SC430. One side works fine, the other only works in high beam. Since I have to get my car inspected, this won't pass. I know I need to drop the bumper as I did when I replaced the turn signal bulbs, but I'm confused about what bulbs I should be getting. Since I have to drop the bumper for the DRL lights, I figured I should change the fog lights since I'm there.
Is there an LED Fog light replacement you'd recommend from iJDMToy?
What bulb would you put in for the DRL? I do not want to go LED as I actually do use my brights. I would like a whiter color to better match the headlights, if this is possible.

I am trying to replace the trunk lights in my 2006 SC430. How do you remove the light covers? It seems like they should just pop off, but reasonable amounts of pushing and pulling has produced zero result. I don't want to break it.

The outside temperature has been cold since the purchase of my 07 SC almost 2 weeks ago (below freezing F ). The A/C green light has not been lit. My 05 SC, the light was on all the time. Dealer says the system will turn the A/C off in certain circumstances in very cold conditions.

My issue is that when I tap on the brake light it doesn't come on. I need to press on it hard for the light to come on. How exactly do you adjust the brake light switch sensitivity?

Yesterday, my SC430 started screeching and the VSC lights came on. I had never heard this alarm before -- sort of between a whistle and a screech. I was a few blocks from home, so I continued on. I did not notice if the ABS light was on at this time, but I don't think it was, because I would have noticed an unusual light on the dash.
I disconnected the battery briefly, but not 3 minutes, and the alarm continued when I switched the car on. This morning, I disconnected the battery again, this time for more than 3 minutes. Again, the alarm screeched when I started the car and pulled out of the garage. I switched it off, and then back on, and the alarm stopped. I thought I had solved the problem. I was wrong.
Later this morning, I drove to the bank, and when I took it out of drive after visiting the ATM, the alarm started again. It continued until I got home. This time, the ABS light is on, in addition to the VSC lights.
On the way to the bank, I made one fairly hard stop at a yellow light, but I have made far harder stops without any lights -- and especially annoying alarms -- coming on.
None of the posts I have found here mention this alarm when the ABS light is discussed.
I have checked the brake fluid level, and it was full. The car was in a Toyota dealership last month for its 120,000-mile timing belt, and the rear brake shoes and rotors were replaced then.
I have yet to begin checking the fuses, but I don't really think this is the problem. Before I try bridging the post in the computer terminal, I plan to visit the local auto-parts store that will read the computer for trouble codes.

I want to disconnect a wire to turn off the tire warning light. I've heard several wire options behind the glove compartment but it's confusing. Any easier clearer answer as to which wire is the right one?

So I was driving today with the fuel light on, drove for 5 miles and the car started dying. I was under the impression there would be atleast 2 gallons left. How many miles we have left when the light turns on?

The back light on my wife's Nav and climate and radio do not work at night when the lights are on. During the day they work and at night if the lights are off they work. Did a search and could not find similar problems.

My tire pressure light has come on - it did once before about 8 months ago. All tire (not flatruns) pressures seem fine (between 34-38 not cold). Tires were rotated by dealer not too long ago. Do I need to reset the pressure light - understand it is somewhere under driver side dash? Previously I think I added air and light went off. But this time tires don't need air.

Noticed a slight vibration from my engine at idle. Nothing too overbearing but just had a concern. How much should I expect if the engine mounts need replacement? Parts? Labor?

When I am driving at a higher speed and I need to pass someone or accelerate, the engine bogs down. I push the peddle to the floor and nothing. This does not happen all the time but it happens. But when I accelerate from a light or lower speeds there does not seem to be an issue. I recently had the value gaskets replaced because of a small oil leak and it seems this problem began after then. I have taken it back to the shop but the problem does not duplicate itself when they test drive it.

I got 2002 SC430 with 59,000 Miles, all of the sudden my car doesn't have any acceleration at all. When I press gas paddle it doesn't do anything, but engine stay on. I couldn't get any error codes since I changed batteries to make sure if it wasn't the battery..
