    • Diagnostic Procedure Instructions provide an overview of each diagnostic category.

DTC Descriptors

DTC C0558 55: Calibration Data Too Few Transitions

DTC C0558 5A: Calibration Data Not Plausible

Circuit/System Description

The hand brake control module has an internal motor, apply actuator, release actuator, and temperature sensor. The hand brake control module also contains the logic for applying and releasing the hand brake when commanded by the hand brake control switch. When the hand 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

C0558 55

The hand brake control module detects a calibration malfunction.

C0558 5A

The hand brake control module detects mechanical problems with the hand brake system.

    • The electric hand brake is disabled, switch command will not be accepted.
    • A message and/or a warning indicator may be displayed.

C0558 5A

    • The electric hand brake is disabled, one release allowed.
    • A message and/or a warning indicator may be displayed.

Circuit/System Verification

  1. Ignition ON, command the Hand brake Cable Service Apply ON with a scan tool. Verify the Hand brake Cable Position parameter is below 1250 counts.
  2. If greater than the specified value, make sure the hand brake cable is connected properly and check hand brake linings for excessive wear, and ensure proper clearance to drum.
  3. Verify DTC C0558 is not set.
  4. If DTC is set, perform the Hand brake Calibration procedure in Configuration/Reset Functions.
