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 performs one initialization test each ignition cycle. The initialization of the electronic brake control module occurs when both the following conditions occur:
- The vehicle speed is greater than 20 km/h (12 MPH).
- The stop lamp switch is not applied.
The initialization sequence cycles each solenoid valve and the pump motor, as well as the necessary relays, for approximately 1.5 seconds to check component operation. The electronic brake control module sets a DTC if any error is detected. The initialization sequence may be heard and felt while it is taking place, and is considered part of normal system operation.
The electronic brake control module defines a drive cycle as the completion of the initialization sequence.
