DTC Descriptors
DTC C0298 00
- Park Brake Unlatch Switch Circuit Malfunction
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
The parking brake control module detects the apply or release button was activated for more than 90 seconds.
Action Taken When the DTC Sets
A message and/or a warning indicator may be displayed.
Conditions for Clearing the DTC
* The parking brake control module clears the history DTC when a current DTC is not detected in 40 ignition cycles.
* The condition for the DTC is no longer present.
* The park brake control switch button is released using the scan tool.
Diagnostic Aids
Check if the park brake control switch is stuck in the apply or release position which may cause the DTC to set.
