Self-Diagnostic System: Notes

WARNING: This page is about a different car, the 2000 Isuzu Hombre. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If PCM requires replacement, PCM must be reprogrammed using a Tech II or other OBD-II compatible scan tool. Some models may require additional equipment to program EEPROM.

NOTE: See PIN VOLTAGE CHARTS and SYSTEM WIRING DIAGRAMS appropriate system wiring diagrams articles for PCM harness connector, terminal and wire color identification.

NOTE: Vehicle Control Module (VCM) may also be referred to as Powertrain Control Module (PCM).

NOTE: Perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm impedance unless stated otherwise in test procedure.
