All,

Newbie to posting on the board, but long-time Aztek owner and shade tree mechanic and board lurker. Wanted to provide feedback on this problem and how I resolved it.

Problem started with the Service Traction System light and disabling of ABS system after turning extreme left. Restarts of car cleared, rare, so I poked around for info without any urgency.

Rate of incidence started increasing, and it began to occur on mild left turns, sometimes while sitting in the parking lot w/o moving forward or reverse (but turning left). Began to think it was driver side front ABS harness/connector or speed sensor. Quickly after that it started turning on when I thought about turning left. OK, not really that bad, but any left motion would trigger it.  This played out over 6 months.

Looked around for ABS code reader app, but wasn't willing to spend $25+ to see if it would work on Azteks. Finally gave in and took it to a trusted shop.  They gave me this nugget, which is the whole point of the post:

          "Azteks and Rendezvous ABS problems are usually harness-related
          due to not being quite long enough to handle steering
          turns. Left turn causing the issue usually is the right-wheel harness connector
          pulling loose.  He said it would be easy to diagnose in a couple of minutes.
          If the ABS error says right wheel sensor, it's the harness. If it says
          left wheel, it's like the left wheel sensor."

It was the harness on the right side just as he said.  Unfortunately for me, I told him to make it go away without asking price... his price for the harness was $125 with $75 diagnosis and labor. I'd priced the kit online for the harness and sensor at $25 plus shipping.  Total bill was shop's $225, problem solved, no add'l time required so... good enough.

So there you are... hope this info is helpful to somebody.
