This bulletin is being revised to include an additional condition. Please discard Corporate Bulletin Number 06-05-25-005 (Section 05 - Brakes).
Condition
Some customers may comment that the low traction indicator and/or ABS lamp may be illuminated with no wheel slip.
Cause
This condition may be caused by an insufficient air gap between the rear wheel speed sensors and the reluctor.
Correction
Check the air gap measurement between the reluctor and the speed sensors on both rear wheels. Adjust with a shim if required.
1.
Check the air gap between the reluctor and the sensor on both of the rear wheel speed sensors. The air gap must be 1.5 mm (0.059 in) to 2.0 mm
(0.079 in).
^
If the air gap is within specification and the customer concern is still present refer to the appropriate diagnostics in SI.
^
If the air gap is less than 1.5 mm (0.059 in) a shim P/N 90278359 must be used to achieve the correct air gap spacing.
1.
Remove the speed sensor. Refer to Rear Wheel Speed Sensor Replacement in SI.
2.
Install the shim.
3.
Install the speed sensor. Refer to Rear Wheel Speed Sensor Replacement in SI.
2.
Verify that the customer concern has been resolved.
