DTC C0558 55
- Calibration Data Too Few Transitions

DTC C0558 5A
- Calibration Data Not Plausible

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

Ignition OFF, ACCESSORY, or RUN mode.

Conditions for Setting the DTC

Circuit/System Verification

1. Ignition ON.

2. Verify that DTC C0558 55 is not set.

• If DTC C0558 55 is set

1. Program the K83 parking brake control module. Refer to Electronic Parking Brake Control Module Programming and Setup Testing and Inspection.

2. Ignition ON. Apply and release the park brake.

3. Verify the DTC is not set.

• If the DTC is set,
replace the K83 parking brake control module.

• If the DTC is not set

4. All OK.

• If DTC C0558 55 is not set

3. Verify the scan tool Park Brake Cable Position parameter is less than 1251 counts.

• If 1251 counts or greater

1. Verify the park brake cable is connected properly. Refer to Park Brake System Diagnosis Component Tests and General Diagnostics

2. Check park brake pads for excessive wear. Refer to Disc Brake System Diagnosis Disc Brake System Diagnosis

• If less than 1251 counts

4. All OK.
