Hub Bearing Replacement but VSC ABS ! Error

Hi Guys,

Thanks for taking the time to read through my post. I have been a member since 2007 but do not post regularly and this have since forgotten my username and password :-( I have created a new account and hopefully be a more active member. Thanks in advanced for any help.

Our Prius is a second generation from 2006. Over the weekend the right front hub bearing was replaced (by Pep Boys). This was their diagnosis after we reported hearing "humming" noise from the front side of the car. They did a test drive around the block and they said that this was the problem. True enough, the noise went away after they have done the procedure. Unfortunaltely, the ! ABS VSC lights are now constantly on. I noticed this when I drove the car going home (about a mile away). I quickly did my research here in Priuschat and read about the reset procedure by jumper pins 4 and 13 on the DLC together with pumping the brake pedals as described in the posts.

This immediately solved the problem with the lights. They were off now and everything was back to normal. I then did a test drive, and lo and behold, when I hit on the brakes, no matter how soft, the car jerks as if the ABS was engaging. This happened twice before the ! ABS and VSC lights again went off. As soon as the error lights went back on, braking became normal once more - no more jerky and intermittent braking.

I then drove home and did the jumper procedure again to make sure that the first attempt wasn't just a fluke. I had the same experience as before - car braking became intermittent and jerky. The ! ABS and VSC lights again turned on - and right after, braking became normal.

I know its too late now but I have to bring it back to Pep Boys. I should have taken this into a dealership. I had to take the car to work today but will be bringing it in tomorrow. Hoping someone can give us some advice on what to do next or what to tell the technician. Thanks again.

 

Thanks so much sir. I will let them know what you wrote. Will definitely post back what happens. Hoping this will be an easy fix.

 

Pep Boys says that the ABS sensor needs to be replaced. They said that since they replaced the hub bearing, they also have to replace the sensor. Reading this forum a lot leads me to believe that they don't have a clue to what's going on.

Unfortunately, another problem came up - the dashboard brake light is now also on even if the foot parking break is released. I don't know if its psychological or what but I do feel that the car is sluggish. I don't know whats going on anymore. This car was super reliable before this mess. Ditched Pep Boys and have dropped it at the dealership. Will post updates when I get them.

 

Thanks so much for the encouragement. Unfortunately I don't have time nor the tools to tinker. The dealer says that the 1 - dust cap was inserted the wrong way and 2 - there was a loose bolt that virtually damaged the hub. I don't have the exact number but the bottom line is - they have to redo everything. This is such a heartache. Savings will now go to this repair.
