NHTSA Complaint #10723238 — 2002 TOYOTA SEQUOIA

NOW, BEFORE WE CHANGED THE AXLE A NEW ISSUE POPPED UP AS THE ABS MODULE CAUSED THE VSC SYSTEM TO ENGAGE AT LOW SPEED BELOW 10 MPH. AFTER 10 MPH THE SYSTEM WORKED FINE. DURING THAT ENGAGEMENT OF THE SYSTEM I COULD HAVE BEEN KILLED BY ONCOMING TRAFFIC OR INJURED VERY BADLY. SO, THE MECHANIC WENT BACK TO CHANGE OUT THE LEFT AXLE AND DID A DIAGNOSTIC TEST ON THE SENSORS, WHICH THE LEFT FRONT WAS NOT READING AND THE RIGHT WAS INTERMITTENT. THAT WAS BAFFLING TO THE MECHANIC, SO WE TALKED AND CHANGED BOTH SENSORS AND THE LEFT AXLE. HE CHECKED THE VEHICLE AND THE VSC SYSTEM STILL ENGAGED AT THE LOW SPEED BELOW 10 MPH, MOST OF THE VIBRATION WAS GONE BUT SOME WAS STILL THERE AT 70 MPH, WHICH HE AGREED WITH ME THAT IT COULD BE POSSIBLY THE DRIVE SHAFT THAT TIES INTO THE 4 WHEEL DRIVE SYSTEM. SO HE DECIDES TO DO THE DIAGNOSTIC TEST IN THE 4X2 MODE AND 4X4 MODE ON ALL THE SENSORS ON EACH WHEEL. IN THE 4X4 MODE ALL THE SENSORS CHECKED AND READ FINE. THE 4X2 MODE CHECK OF THE SYSTEM REVEALED A PROBLEM WITH IN THE SYSTEM THAT TIED TO THE ABS CONTROL MODULE. SO, AS OF NOW HE HAS WORKED WITH ME TO REALLY UNDERSTAND THE PROBLEM WITH THIS VEHICLE TYPE TO TRY TO GET TO THE ROOT CAUSE. HE HAS SINCE NOT CHARGED ME FOR THE SENSORS, UNTIL HE CAN GET THE ABS MODULE CHECKED OUT THROUGH A CERTIFIED REPAIR MANUFACTURER WHO WORKS ON THESE PARTS ON A REGULAR BASIS.
