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.
Circuit/System Testing
Disconnect the EBCM harness connector. Connect a test lamp to ground, at the EBCM harness connector touch the test lamp probe to each of the 3 battery positive voltage circuits. The test lamp should illuminate on all 3 circuits.
- If the test lamp does not illuminate on one of the battery positive voltage circuits, repair open or short to ground on the suspected circuit.
