C0293 GMC Description
The electric handbrake control module has an internal motor, apply actuator, release actuator, and temperature sensor. The electric handbrake control module also contains the logic for applying and releasing the handbrake when commanded by the electric handbrake 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 handbrake 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.
