Power Circuits

WARNING: This page is about a different car, the 2003 Isuzu Rodeo Sport, 2003 Isuzu Rodeo, and 2003 Isuzu Axiom. However, it is still accessible from the selected car via links, so may be relevant.

Using DVOM, backprobing measure voltage between ground and appropriate PCM harness connector terminals. See POWERTRAIN CONTROL MODULE POWER CIRCUIT TERMINALS table. If battery voltage is not present, check ignition related fuses. If fuse is okay, check for an open in wire between battery and ignition switch, and between ignition switch and PCM terminal. If circuits test okay, check for a defective ignition switch.
