Initialization Sequence



Initialization Sequence

The electronic brake control module performs the Initialization test once each ignition cycle, when the vehicle speed reaches 15Km/h (9 mph). The Initialization sequence cycles each valve solenoid and the pump motor (as well as the necessary relays) to check component operation. If any error is detected, the EBCM will set a DTC. The Initialization sequence may be heard and felt while it is taking place, and is considered part of normal operation.
