Self-Diagnostic System: Notes

NOTE: If PCM requires replacement, it must be reprogrammed using 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 articles for PCM harness connector, wire terminal and wire color identification.

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