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.
System Self Test
The ABS performs a series of tests to the ABS components for proper operation and readiness. The initialization starts when the ignition switch is turned from the LOCK to the ON position. The EBCM turns ON the ABS indicator for 3 seconds. When the ABS indicator turns OFF a slight mechanical noise can be heard. This condition is normal. This noise comes from the BPMV assembly as the EBCM tests solenoid valves and the pump motor.
A slight pulsation may be felt when stepping on the brake pedal while the EBCM is testing the solenoid valves and the pump motor. This condition is considered normal brake pedal feedback.
