DTC Descriptors
DTC C0293 01
- Park Brake Switch Control Short to Battery
DTC C0293 06
- Park Brake Switch Control Low Voltage/Open
DTC C0293 08
- Park Brake Switch Control Performance-Signal Invalid
Circuit/System Description
The electric parking brake control module has an internal motor, apply actuator, release actuator, and temperature sensor. The electric parking brake
control module also contains the logic for applying and releasing the parking brake when commanded by the electric parking brake switch. The
electric parking brake module will perform diagnostics on the electric parking brake switch and its wiring harness to verify it is functioning
properly. When the electric 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.
The electric park brake switch control diagnostic checks for failure conditions in the electric park brake switch and associated wiring into the
electric park brake module.
Conditions for Running the DTC
Ignition OFF, ACCESSORY, or RUN mode.
Conditions for Setting the DTC
The electric parking brake module detects a short to battery, short to ground, open circuit, or an internal parking brake switch control malfunction.
