A couple of weeks ago, I had a front end alignment performed on my car at Bobby Garrett's ? here in Dallas. He did a fantastic job.

When finished, he told me "hey, you know your car's throwing codes, right? They were there before I started, right"? I told him that they definitely were not. I had no codes before he performed the work. So we put the car back on the lift again and walked around under there, ensuring that all the tubes carrying the abs/dsc wiring was unbroken and untwisted.

I theorized this out loud with him: "Maybe you got my car all excited by tickling all those wires as you made adjustments to toe and camber. I'll bet you driving will clear the codes."

I stopped to fill the car up around 2 miles away from the shop, and when I started it then, the codes were still present. But I knew I'd have to drive it longer if driving was going to clear them.

Well, I was right. I drove the car the approx. 20 miles home and when I started the car to leave the house, the codes were gone.

Here's the interesting thing: since then, the DSC and ABS codes have thrown a couple of times, separately, since then. I have shut the car off and started it back up each of these times, and the codes have cleared thataway.

So, does anyone care to weigh in on this? Do you believe I should take it in to have all the existing history in the onboard diagnostics read and cleared manually? Or should I just ride on down the road?

 

It is normal when the rear wheels has been spinning for extended time separate from the fronts that the car sets a code for ABS etc - this could have happen during alignment -though it should clear after some miles - I cannot explain that it continues

 

Today it happened that both codes threw at once, for the first time since the alignment. Again, the codes went away when I shut the car off and restarted.

I'm starting to wonder if Bobby might have loosened or displaced something after all.

 

Sounds like a bad connection

 

Orig. battery?

 

yes. original battree.

 

ABS wheel sensor on the way out?

 

I recently had the exact same problem as yourself.
It turned out to be a faulty front wheel sensor.
A 15 minute job by my Indy dealer fixed it.

 

Thanks Les, for your info. How much was the sensor?
