#PIT3707: Information on the Upcoming Safety Recall 05068 Front Wheel Speed Sensor Corrosion - keywords ABS activation brake campaign sensor speed unwanted - (Sep 1, 2005)
1999-2002 Chevrolet Avalanche, Silverado, Suburban and Tahoe
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
These vehicles may experience unwanted antilock brake system (ABS) activation and increased stopping distances during low-speed brake applications (greater than 3.7 mph but less than 10 mph). This condition does not set any ABS codes nor does it illuminate the ABS warning lamp. This condition is more likely to occur in environmentally corrosive areas, based on field report data from the U. S. and Canada.
To correct this condition, dealers are to remove the wheel speed sensor and thoroughly clean the wheel speed sensor mounting surface on the bearing, apply Zinc-X (rust inhibitor) to the cleaned surface, grease the mounting surface, reinstall the wheel speed sensor, and check the peak-to-peak output voltage to ensure the wheel speed signal is within specifications. These repairs will be made at no charge to the customer.
Approximately 804,000 vehicles are involved. GM is working with its suppliers to obtain the required parts as quickly as possible. Based on the anticipated schedule, we plan to begin notifying customers about this recall in November 2005.
GMVIS information for this recall will not be available until the recall bulletin is released to dealers in November 2005.
