Power Circuits

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2003 Hyundai XG350, 2003 Hyundai Tiburon, 2003 Hyundai Sonata, 2003 Hyundai Santa Fe, and 2003 Hyundai Elantra. However, it is still accessible from the selected car via links, so may be relevant.

Turn ignition on. Check for battery voltage at PCM/ECM power terminals. See PCM/ECM POWER TERMINAL IDENTIFICATION table. If battery voltage is not present, check operation of engine control relay. See appropriate ECM CONTROL RELAY under RELAYS .
