Replaced front hub, now idiot lights are permanently on...Help!

Hello all. I have not posted in quite awhile....my 2007 Prius is going strong with 173k miles on it. I recently found that the front Passenger side wheel assembly hub needed replacing, as the wheel bearings just started to show signs of wear.

My mechanic shop, who have been great for years, replaced the drivers side one 2-3 years ago without a problem. Yesterday right after they replaced the other one, I got in the car and saw that three idiot lights that I have NEVER seen on before were now on.....an exclamation mark inside a circle, the ABS light and the VSC light.

I went back into the shop and told them this....they told me that "sometimes it takes awhile for those things to turn off after we replace a big part like a hub....let us know next week if it stays on".

Well, I was not too happy about that, and last night and today I did a lot of driving, so I returned to the shop today for them to "clear the codes" or something. They tried, and the lights just came back on. They said that they did not know why the lights stayed on, but they cleared the codes and the codes were now clear, so that was all they could do.

I've had this car for about 10 years now, and this has never happened. I should say that I also have the TPS light on, but that has been on for years...I keep a good watch on my tires, so I feel I do not need to replace these tire sensors at around $100 a piece just to get rid of that light. They told me that perhaps I should replace those two bad TPS sensors and if I did that then magically maybe all of the lights will go off....but they could not swear to it.

So now I'm angry. I feel they caused this, but they now just shrug their shoulders. I told them I will go on PriusChat and find out from the good folks here how to fix this problem that was never there until they replaced this hub.

I do not know how much longer I will have this car...I love it, but it may be getting long in the tooth....but I certainly could not sell it with 4 idiot lights blaring at me. I thank anyone in advance here who could help me with this new problem.

Respectfully, Frank D.

 

Thank you. They did tell me that no other codes showed up, and that he said the speed sensor should be fine. He said I would not be able to use Cruise control if it was not. I used it without problems. At this point, I totally trust what you and everyone here says before what the shop says. I appreciate hearing from you and others so when I DO go back there next week I am armed with plenty of good information to assist them in making it right. Thank you! Frank D.

 

The lights were not on ever before the hub install. I looked up mini VCI on amazon.....some show a CD, some show just a cord-like item....these seem to range from 17-50 dollars. It appears to plug into the plug under the dash to a usb port on a laptop. Not sure what it will show me....they told me no "codes" showed up from their scanner. Sorry guys...I can build a house and deliver a baby no problem...I am not too smart of a car guy.....

 

Perhaps what you good folks are saying is that their scantool is not good for Hybrids.....thus the recommendation for this mini VCI thing.

 

I see that Amazon has this mini VCI analyzer sold by a place called luckybuy11 for $51.00 Everyone says it works great, but everyone has trouble installing the software. Fortunately they also say the seller is happy to remotely take over your laptop and do it for you. You also need to disable your anti-virus to make it work. Trusting a stranger from halfway around the world to take over your laptop is a bit scary, but they say this is the only way and everyone is happy afterwards.

I apologize, but can you good folks tell me what this will do for me..? Basically tell me what is wrong, or what codes it is causing, even though the shop told me it was all clear?

I change my oil, etc, but am not much of a mechanic. I'm also guessing that this will tell me what two tires have the bad TPMS monitors. I do belong to Costco, so I might have this done...but after I get all three of those other lights to go away.

At this point, I may get this item, as my only other option is to go to the dealership and pay a lot for them to fix this light issue. I also think my brakes feel a bit different than they did before this hub assembly was replaced. Thank you!

 

Thank you all....this is all good info...exactly what I was hoping for. I think I will take a look and also let my son look, (he has replaced hub assemblies before, etc ...I think I should have had him just do this). Then I will return to the shop and if needed go to the dealership before I buy the mini VCI. If I did not read of so many software installation problems I would buy it. Any other ideas are welcome....you have helped me a great deal. Thank you....

 

Thank you all for the great help. I wrote down everything you good folks said and went back to the shop. They took care of it free of charge, and told me that it was the speed sensor. Specifically, they said it was part of the speed sensor that was "inside the spindle", indicating it was not really their fault, but they gladly took care of it. The three lights are now off which is great. I also had two new front tires put on the day before the hub.....since then I have noticed a drop in MPG. I made sure I had 42/40 PSI.....I just refilled, we will see. Hopefully the MPG returns to previous levels. Thank you all again! Frank

 

No..they used good parts, just had the speed sensor a bit misaligned I believe. Thanks!
