Pinpoint Test D : C2005:77, C2006:77: Notes
Refer to Vehicle Dynamic System 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 C3050 for the LH actuator motor and C3134 for the RH actuator motor.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C2005:77 | Right Actuator: Commanded Position Not Reachable | This DTC sets in continuous memory and on-demand if during an apply or release command, the ABS module detects an irregular current draw. |
| C2006:77 | Left Actuator: Commanded Position Not Reachable | This DTC sets in continuous memory and on-demand if during an apply or release command, the ABS module detects an irregular current draw. |
