Circuit/System Description
The parking brake control module has an internal motor, apply
actuator, release actuator, and temperature sensor. The parking
brake control module also contains the logic for applying and
releasing the parking brake when commanded by the park brake
control switch. When the parking brake control module receives a
signal from the switch the internal circuit board temperature is
checked to verify it is within operating range before the control
module performs the requested operation.
Conditions for Running the DTC

Circuit/System Verification
| 1. |
Ignition ON, command the Park
Brake Cable Service Apply ON with a scan tool. Verify the Park
Brake Cable Position parameter is below 1250 counts. |
| ⇒ |
If greater than the specified value, make sure the
park brake cable is connected properly and check park brake linings
for excessive wear, and ensure proper clearance to drum. |
| 2. |
Verify DTC C0558 is not
set. |
| ⇒ |
If DTC is set, perform the Park Brake Calibration
procedure in Configuration/Reset Functions. |
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic
procedure.
