WTB-63B22018-06-11. Service bulletin. ELECTRICAL SYSTEM; PARKING BRAKE. New Service Program: WTB-63 Electronic Parking Brake (EPB). ReprogrammingThe EPB system is designed such that the parking brake will apply upon initial activation and re-apply approximately 150 seconds (2 ½ minutes) after initial activation. Due to improper software programing of the EPB system, if an affected vehicle?s ignition switch is turned to the ?ON? position at the same time the parking brake is re-applying, electric current will be provided continuously to the left rear EPB motor, eventually causing the motor to seize and prevent release of the parking brake. Should the left EPB motor seize, it will be necessary to replace the EPB Motor Gear Unit- EPB LH.
