Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Initialization Sequence
The electronic brake control module (ECBM) performs the initialization test once each ignition cycle, when the vehicle speed reaches 15 km/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.
