Pinpoint Tests
Refer to Wiring Diagrams Cell 42 for schematic and connector information. Normal Operation and Fault Conditions The ABS module measures the current draw of both actuator motors during each parking brake apply request. Current draw measurement for these 2 Diagnostic Trouble Codes (DTCs) starts when the caliper piston and brake pad start moving and stops when the brake pad contacts the brake disc, this is known as free run. If the free run current draw exceeds the programmed limit, the ABS module sets a DTC. This is most likely caused by high mechanical resistance in the actuator or motor, a shorted motor, a blocked motor or a seized motor.

Refer to Wiring Diagrams Cell 42 for schematic and connector information. Normal Operation and Fault Conditions The parking brake switch has 3 positions; APPLY (pulled up), RELEASE (pushed down) and NEUTRAL. The ABS module sends voltage to the parking brake switch and this voltage returns along 1 of 3 circuits. An open, excessive resistance or a short in the parking brake switch circuits or the parking brake switch causes the ABS module to set a DTC.

Refer to Wiring Diagrams Cell 42 for schematic and connector information. Normal Operation and Fault Conditions When the ABS module receives a parking brake apply or release request, the ABS module sends voltage to the parking brake actuator motors. The ABS module also monitors the current draw of the actuator motors to determine when the brake pads contact the brake disc, to determine when the appropriate amount of clamping force is being applied to the brake disc and to determine when the brake pads are retracted to their start position. The actuator motors have a serviceable jumper harness connecting the actuator motor to the body harness at C334 for the LH actuator motor and C316 for the RH actuator motor.

Refer to Wiring Diagrams Cell 42 for schematic and connector information. Normal Operation and Fault Conditions When the ABS module receives a parking brake apply or release request, the ABS module sends voltage to the parking brake actuator motors. The ABS module also monitors the current draw of the actuator motors to determine when the brake pads contact the brake disc, to determine when the appropriate amount of clamping force is being applied to the brake disc and to determine when the brake pads are retracted to their start position. A HS-CAN issue or concern results in a failure to release the parking brake. The ABS module runs self-tests before, during and after an apply or release request. These self-tests are done to determine parking brake system functionality. High actuator motor circuit resistance, a short to ground, a short to voltage, an open circuit, a mechanical or electrical failure of the actuator motor or an internal failure of the ABS module may cause one or more of these self-tests to fail resulting in the ABS module setting one or more Diagnostic Trouble Codes (DTCs). The actuator motors have a serviceable jumper harness connecting the actuator motor to the body harness at C334 for the LH actuator motor and C316 for the RH actuator motor.
