2006 Toyota Sequoia: ABS light or ABS activating

Filed Jul 18, 2018 · Electrical · 96,800 miles · OR

In march 2016, I had - for the first time - the vsc trac, vsc off, brake, and ABS lights on instrument panel come on... All 4 on at once. Then again, today, I had the vsc trac, vsc off, and brake lights come on. A known issue for both sequoia and tundra models, owners have tried to get a recall. Many thoughts online about what causes this; it appears it's a faulty skid control unit (ecu unit). Says the ecu will take the vehicle into a "safe" mode and limit output power and acceleration, until this is resolved. I experienced this today after the lights came on. Others online say might be a bad brake fluid sensor, brake pedal switch or oxygen sensor. However, overwhelmingly it seems to be a faulty ecu' and this is a very expensive electronic part ($2,300)!

When taking turns at mild acceleration the slip indicator light will flash and the vehicle loses acceleration. This generally happens when taking a left turn from stop while entering traffic from a side street onto a main road. Generally at the intersections there are a small grade change for water drainage, this will cause uneven surface when driving across and cause a minor rocking of the vehicle. This is has produced dangerous situations on multiple occasions where the loss of acceleration leaves the vehicle in the oncoming lane longer than desired and could easily result in a serious collision. I have found similar complaints on multiple forums that have references the cause being associated with ABS sensor or yaw sensors. Would love for this to be investigated and a solution provided.

The trac off light and vsc light and ABS light comes on, on the dash. When you make a turn the vehicle looses power and stalls in the road. The steering is all over the road and it doesn't have the stop time as it did.

Vsc trac on/off brake indicator lights appear while driving in the 35-45mph range. If you attempt to stop the vehicle (firm or light brake pressure), there is a loud grinding noise, as if it is activating the ABS, which takes a little longer to come to a complete stop. It would've been nice if toyota created a vsc trac on/off switch (at this rate, I may have to create my own). Some websites mention dirty sensors (speed sensors), some mention possible faulty yaw rate sensor (level warning switch, located in the center console), steering angle sensor may need adjusting. Who knows, but this would be a definite accident waiting to happen. I'm surprised this hasn't been considered a recall? Http://ww2.justanswer.com/uploads/ts/tsmodie/2012-10-29_191900_1.gif

Just like every other 2006 sequoia at 80k miles the yellow ABS, yellow vsc off, yellow vsc trac , and red brake dashboard lights came on causing it to fail the ma state inspection. Disassembled p/n 44050-0c100 and the brushes in the ABS pump motor (ate 25.0206-0206.3) are completely gone.

Trac control, check engine light,vcs lights, ABS lights, and brake warning lights all came on at once as I started vehicle one morning.

Multiple incidents and multiple trips to dealership with nothing resolved. Abs activates with vsc lights at low speeds when reversing out of driveway, driving slowly down road, etc... No reason I can think of for it to engage. Vehicle makes a loud grinding sound and feels like it won't stop. Very common issue from what I see already reported. Yaw sensor replaced to fix another vsc issue when making left u-turns...almost got in accident when the brakes kept me from completing a u-turn with traffic coming...luckily I continued into driveway without incident. This happened after the above but the above still continue to this day so it was not the cause.

When making left or right turns at slow speed, traction control light blinks, sometimes with beep alarm and sometimes engages the ABS system. Very dangerous when pulling out into traffic to not be able to accelerate since you lose control of driving the vehicle for about 3-5 seconds.

Abs system goes on without warning leaving me unable to brake, usually when I am backing out of a parking space & it's cold outside. Has happened intermittently over the last year. When I turn the car off & back on it seems to clear up the issue. Took it in and was given the codes c1223 (fault in ABS system), c1247, c1310, was then referred to a dealer. Did some research online & saw I am not alone so wanted to report it. Also 2 years ago we had our latch break on the rear door, had to have it replaced to open up the door, this has happened to many many sequoias!!

Abs, trac, vsc and brake and check engine lights all signaled fault codes. Codes are #1251 and #1223, again, this after computer module was replaced at full cost to the consumer $1,059. The same fault has re-occurred in less than 6 (six) months of having replaced the ABS, trac, vsc computer module.

Codes c1223 (ABS control system malfunction), c1247 (stroke sensor), and c1251 (pump motor is locked/ open circuit fault) had to replace vsc module/computer at my own cost.

My vsc trac, vsc ff and ABS light come on. This problem seem to happen on most of the sequoia. The dealer told me it the rate sensor need to be replaced.
