General, ABS & VSC Warning Light - ON - What Causes?

Last week I bought a 2006 Prius. Two days later I heard a noise brought it to a Toyota deader and they replaced the right front wheel bearing. The noise stopped. Then about 40 miles later on an interstate the General, ABS, and VSC yellow warning lights came on. I to it back to the dealer (the lights went off when I got off the interstate) and they cleaned an external connection and but said there could be some grease inside and the light could come back on but it was safe to drive. I proceeded and the light came back on. The lights stayed on while driving it about 1,000 miles home. Then in the morning after the lights came on after driving it about 15 miles, I again to it to a Toyota dealer and paid 90+ dollars to diagnose the lights and a little to fix it, Ten 5 miles down the road the lights came on again. I drove back to the dealer and they said something like: "There is a lot of rust on the rotor etc. that probably was loosened when the wheel being was replaced and that is interfering with the speed sensor. And that the knuckle has swelled. I asked what it would take to fix it and that I was not interested more diagnostic fees. They suggested to drive it some and bring it in and they would lock at it again and advise how to fix it efficiently.

Has anyone had experiences with these warning lights or suggstions as to how to fix them efficiently?

 

I have uncovered the battery enough to see it is a Toyota battery but can see a manufacture date. I am working on getting the battery out to see. I bought it used it was serviced at Toyota every 5,000 miles except one. The service record had not mention of a new 12V battery. How does one check to see if Ok?

 

how many miles on her?[/QUOTE]

2 separate dealers one in New Mexico. on a Friday afternoon and the other in Arizona. It has 108,000 miles.

 

I bought it as is from a private party.

 

This morning I looked at the battery. It is a Toyota 84 month Battery. On top center of it is a Round green sticker that reads K13. I presume the K stands for November and the 13 stands for 2013. December 18th, 2013 a the dealer installed a new hy-bred battery. Do you think a new starter battery was also installed?
A voltage reading was 12.39V. Is that good or not so good?

 

Also, I did not see any vent tube. Where should it be? Never took it all the way out as the battery vent duct is in the way. Could not feel it on any side. Should I get one and install it?

 

Hi thanks for your help. How I measured it:
1st as you said pop hood next morning with multi meter 12.60V high number, but reading jumping all over place I think because could not make a good ground.
2nd from battery terminals with multi meter 12.39V
3rd after charging with battery minder 2012-AGM 13.18V again with multi meter.

How does one measure voltage of the starter battery or any battery with a computer?

Own it for only 2 weeks, to new to tell if MPG is decreasing. Although maybe it seems to vary from 37 to 44+ on the highway.

I am game, But which one do I buy and what software and / or on line services do I need. I assume this will also give me all the error code. Will It also give me what they mean. I have a 2006 Prius.

Thanks all for your insights. What it turned out to be was a broken tooth on the ring the wheel speed sensor picks up. As such the the Toyota dealer in Texas who changed the wheel bearing picked up the cost of the repair. Three cheers for the Toyota dealer. Fred
