THIS IS AN UPDATE TO A PREVIOUSLY SUBMITTED REPORT FOR ABS FAILURE ON THIS VEHICLE. THE INCIDENT DATE ON THIS REPORT IS APPROXIMATE. THE TWO WIRES TO THE RIGHT FRONT ABS SENSOR WERE SEVERED BY INTERFERENCE WITH THE UPPER CONTROL ARM AND THE DISK BRAKE BACK PLATE/SPLASH SHIELD, TO WHICH THE WIRING IS ATTACHED WITH RIVETED METAL CLIPS. IT APPEARS THAT THE WIRES BECAME TRAPPED BETWEEN THE UPPER CONTROL ARM STAMPING AND THE HUB AND/OR DISK BRAKE BACK PLATE/SPLASH SHIELD, POSSIBLY DURING TURNS THAT CYCLED THE FRONT SUSPENSION. THE WIRING INSULATION IS WORN IN SEVERAL LOCATIONS OTHER THAN THE BREAK POINT, AND THE FIRST METAL CLIP HAS BEEN TORN OFF THE POP RIVET THAT HOLDS IT TO THE BACKPLATE/SPLASH SHIELD. THIS IS THE SECOND TIME THIS WIRING HAS FAILED DUE TO THIS DESIGN OR INSTALLATION DEFECT. THE FIRST FAILURE WAS REPAIRED UNDER WARRANTY. NO REPAIRS HAVE BEEN PERFORMED AT THIS TIME AS WE HAVE BEEN WAITING FOR RECALL INFORMATION FROM GM, WHICH ARRIVED RECENTLY, BUT IT ADDRESSED AN ABS PROGRAMMING PROBLEM THAT AFFECTED BRAKING ON SURFACES THAT TRANSITIONED FROM WET TO DRY AND BACK. *AK
