Condition:
ABS light comes on with Code # 25 (left front wheel speed sensor fault) and Code # 35 (rear axle speed sensor fault).
Cause:
A voltage may be induced in the right front wheel sensor wire if it is too close to the spark plug wires.
Correction:
To improve this clearance, the speed sensor wire bracket was moved on the frame to allow more clearance from the plug wires. This is
on all vehicles built after VIN # MW187731.
