Powertrain Control Module Connector Terminal Identification: Notes

NOTE: Three types of engine control modules are available and are used according to engine configuration. All 2.2L (VIN 4), 3.4L, 4.8L, 5.3L, 6.0L and 6.5L vehicles are equipped with a Powertrain Control Module (PCM). All 4.3L, 5.0L, 5.7L (gasoline) and 7.4L vehicles are equipped with a Vehicle Control Module (VCM). Vehicles equipped with 5.7L flex-fuel (gasoline and CNG) engines use both PCM and an Alternative Fuel Engine Control Unit (AF ECU). The AF ECU controls CNG operation, PCM controls gasoline operation.
