Power Circuits

WARNING: This page is about a different car, the 1996 Isuzu Rodeo. However, it is still accessible from the selected car via links, so may be relevant.

Turn ignition on. Using a voltmeter, backprobe PCM harness connectors. Check for battery voltage between PCM ignition power terminals and ground. See PCM BATTERY CIRCUIT TERMINALS table. If battery voltage is not present, check IGN fuse and fusible links. If fuse is okay, check for an open in wire between battery and ignition switch, and between ignition switch and PCM terminal. If okay, check for a defective ignition switch.
