ABS skid control (ECU) and booster assembly malfunction. Dealer reports this as a safety concern that should not be happening and seems to be a pattern and concern yet Toyota refuses to address the issue.

I have had an issue with my 2003 Toyota Sequoia. The ABS and vsc trac lights came on. I have searched online to find out about this problem and have found it to be a habitual problem. On the morning of May 24 I had a collision with a deer. All four brakes locked up and I went into a skid and hit the deer. The things that I have read is its a electrical problem but it is not. Toyota has an issue here that puts its owners in an unsafe situation. This needs to be fixed. If there were habitual seat belt issues or airbag issues this would be taken care of. This is a major safety issue because I though I had working ABS brakes and due to some kind of design failure I did not.

Within a month of purchase in January 2003 the vsc & trac light were coming on upon vehicle start up sporadically for several weeks. On occasion the engine light would also come on. Sometimes I would have a foot on the gas & it felt like the brake was being applied. I brought the vehicle in several times, and they said their wasn't an issue. I left it overnight and the lights didn't come on at 2000 miles. This continued sporadically for a year usually during colder weather. In January 2004 at 16,870 miles the vcs/trac came on when near Toyota and finally was validated & replaced due to tsb BR002-03, part#89630-0C011. The issue still continues still in colder weather. In December 2005, at 48,000 the vcs/trac & engine light were on, and stayed on all day & Toyota replace the cat converter. Two weeks later I return with all three lights on & they replace the cat converter again. Now the issues are sporadic all year long. In August 2008 at 89,000 miles during service work they are able to pull codes with vsc/trac lights off. They replace ECM to correct steering angle & deceleration. The lights still came on last week again at start up and the vehicle slowed down pulling out of the driveway. Still looking for a resolution...

Vsc/trac/ABS lights have been a nagging problem with my 2003 Toyota Sequoia the entire time I have owned it. I have had the Sequoia to the dealer multiple times. The dealer has replaced both a sensor during one visit and the computer during another visit. Still, intermittently one or two times a month, the lights come on while driving even on straight dry clear roads. Pulling over and turning the engine off and re-starting the vehicle will sometimes turn the lights off but not always. I was told by the dealer that when my lights are on I do not have use of the vsc/trac or ABS systems. Unfortunately, when I take the vehicle to the dealer the lights have turned back off so there is no way to diagnose the problem. This in itself is a safety concern. You can bet that I will hold Toyota accountable if there is ever an accident when these lights are on. This has absolutely made me upset to the point that I will never purchase another Toyota ever again unless Toyota issues a recall and replaces all of the sensors and related computer components so that the lights go off and stay off. I do want to mention that when the car was just a few days old the battery failed on me. Upon taking it to the dealer I found out that internally some of the battery cells came loose from the connectors which did not give me enough voltage or amps to crank the engine over. This was replaced free of charge but I still wonder if this caused some sort of damage to the vsc/trac/ABS electrical system components.

While driving along at city street speeds, during dry weather, on paved roads, my vsc trac and trac off lights come on. No other warning lights come on. Then a buzzer sounds for about 3 seconds. Then at the same time, a strange grinding sound comes from underneath the car, and the brakes seem to start working for no reason. I quickly pull over, turn off the car. I check the outside of the car and see no indication of running over anything. I then start the car and all the lights are back to normal (off). This happens about 2-3 times a month, for about a month or 2 now. I have not been able to determine any problems.

Brake light comes on intermittently. Dealer says the skip control computer which includes vsc/ABS brake system on vehicle, this is an expensive fix. My last service on this vehicle was a complete brake replacement after which the brake light started to come on at random. The brake light has to be on in order to check the vehicle, which is an inconvenience in itself. I finally managed to catch the brake light on and this is what I was confronted with. No injuries or death so far it that what it's going to take to have this problem corrected.

I have a 2003 Toyota Sequoia SR5 4WD. It has been giving me the same problem since I bought it in 2003 brand new. The vsc off light and engine check lights are on almost all the time. I brought it to the dealer several times and they told me that it was due to the sensors on the brakes or that I needed a new brake pad and rotor. I have been doing the replacement deals for the past three times already and it is still giving me the same problem. I found out that there are many car owners who have reported the same problem and that it is due to a computer malfunction. It becomes a greater problem because the computer disables the vehicle control mechanism resulting in loss of skid control. The brakes fail to engage and there is no traction during a skid. It is a potentially hazardous situation when driving during the winter or when it is raining and the roads are wet and slippery. I was told to unplug the battery and plug it back it to restart the computer but it does not keep the vsc off and engine light from coming on. I am bringing it to the dealer again and hope to get them to really fix the problem. Since this problem has been reported by many car owners, there should be a recall and the highway safety commission should require Toyota to fix this problem for all owners for free.

Vsc/trac off & ABS failure requiring computer and yaw sensor replacement. I took my 2003 Sequoia to the local dealers service dept. In 2006 because the lights mentioned above were on. They could not find anything wrong. I told them the car was making a loud noise and the steering wheel was pulling to the side - very hard to control. They could not mimic the problem and told me there was nothing wrong. I argued with them, but lost that argument. Luckily for me the battery needed replacing in a few months, and when replaced problem went away. Now that my warranty has expired (last month) the vsc/trac off and ABS lights are on again. I didn't rush it in because of my prior experience or I would have had it in while it was under warranty. Now they want $2200 to replace computer and yaw rate sensor. I see this is a very common problem and I am very unhappy with the service department and Toyota. I contacted Toyota and they refuse any responsibility although this is a very well know issue. It could be very dangerous under the right conditions. Luckily my driving is in a very small community and I don't drive very fast.

Vsc off and vsc trac warning lights keep coming on along with check engine light. Had reset every time. Dealer is vague on cause and says probably gas cap seal. Replaced oxygen components one time. Happening again. I suspect faulty part or computer with the car that is not yet documented.

Similar complaint as many. I have a 2003 Toyota Sequoia the vsc/trac light is on. Dealership says skid control computer needs to be repaired. But computer scanner shows no codes that verify any defects.

Vsc, ABS and trac light coming on.

- Clovis, CA, USA

I bought 2003 Toyota Sequoia. I am getting the vsc traction control and ABS light on. Checked with other Sequoia owner and they have similar problem. I went to checked the car and was told that the ECU computer is faulty. The faulty ECU needs to be replaced. Since this is wide spread problem with 03 Sequoia it should be recalled. This is a safety issue. Here are the codes: C1203, C1223, C1244.

Vsc off, ABS, brake and tcs lights came on at the same time only at full stop (engine running). As soon as taking off (driving) with over 5 km/hr, all light went off. Stopping the vehicle, all light will came on again. This cycle repeating with each and every stop. Dealer determined than one of the vacuum hose cracked and reduced pressure at idle would cause light to come on. Once hose have been replaced, problem was resolved. Strongly advise Sequoia owners before replacing any commuter components or expensive module, to talk to their dealers and have the vacuum system checked prior to any other steps. It is the less costly repair before any major ones.

Skid control ECU module does not work on 2003 Toyota Sequoia. Vsc /trac lights come on. Nothing should have made this component fail dealer will not replace - out of warranty. Multiple similar problems discussed online yet manufacture will not admit issue with workmanship. Toyota needs to do a recall on this part (895410C062).

03 Toyota Sequoia. Vsc, ABS, parking brake light came on. At 52,000 miles while driving. Yaw sensor defective.

- Vacaville, CA, USA

The ABS and skid control lights are on in my 2003 Toyota Sequoia. The dealer states that the skid control computer needs to be replaced. So right now, there is no skid control or ABS available on my car because of this computer is bad. Toyota will not do anything about it and I have filed a complaint case 200810010613. This is a safety issue.
