The parking brake control module has an internal motor, apply actuator, release actuator, and temperature sensor. The handbrake control module also contains the logic for applying and releasing the handbrake when commanded by the handbrake 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.
Ignition OFF, ACCESSORY, or RUN mode.
The handbrake control module detects a short-circuit to battery or a short-circuit to ground.
The handbrake control module has detected an internal temperature that is above the allowed value.
• | A message and/or a warning indicator may be displayed. |
• | The electric handbrake is disabled, one release allowed. |
• | The handbrake control module clears the history DTC when a current DTC is not detected in 40 ignition cycles. |
• | The handbrake control module is replaced or the internal temperature drops below the allowed temperature. |
Check for debris on the handbrake control module which may cause the module to overheat.
