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.
Power Circuits
Turn ignition off. Disconnect ECU connector. Using a voltmeter, check terminals No. 12, 14, 19 and 34 for battery voltage. If battery voltage is not present. Check fuses No. 15, 18 and 24. If fuses are okay, check for open in wiring between ECU and fuse box. See WIRING DIAGRAMS for terminal identification and wire colors.
