Service Mode
Service mode is also known as maintenance mode. The parking brake system must be placed in service mode to service the rear brake pads or when removing rear brake components to service other components. The system can be placed in service mode by using the diagnostic scan tool or by following the steps in the EPB Service Mode Activation and Deactivation procedure. Refer to: Electronic Parking Brake (EPB) Service Mode Activation and Deactivation .
Once the system is placed in service mode, the message center will display MAINTENANCE MODE, the yellow parking brake indicator illuminates and the parking brake system is deactivated. The only way to reactivate the parking brake system is by correctly exiting service mode. Disconnecting the vehicle battery will not reset the system or exit service mode. If the vehicle is driven greater than 8 km/h (5 mph) while in service mode, the yellow parking brake warning indicator is illuminated, the red BRAKE warning indicator flashes and a warning chime sounds.
