EPB Module Screech / Noise from Parking Brake / Parking Brake Shoe Drag Diagnostic Procedures
AFFECTED VEHICLE RANGE
CONDITION SUMMARY:
Situation:
Vehicles may exhibit one or more of the following issues:
^ A rubbing / squeak noise from the rear / parking brake when the vehicle is moving.
^ Evidence of parking brake shoe-drag (heat build-up / excessive parking brake shoe lining wear).
^ A screech noise when applying or releasing the Electric Parking Brake (EPB) while the vehicle is stationary. The EPB warning lamp may be
illuminated and DTC C1A43-00, C1A53-68 and / or C1A46-62 may be stored.
The parking brake shoes may be corroded, worn, or incorrectly adjusted, causing excessive lining wear and / or noise and heat. If the condition has been
present for a while, the internal components of the EPB Module may have over-traveled and may be jammed.
NOTE:
If the root cause of the parking brake issue is incorrect adjustment related to a previous repair, a Warranty claim may not be made for the repair.
Action:
In the event of a customer concern of any of the above, refer to the appropriate Diagnostic Procedures outlined below.
