Power Circuits

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.
