Computerized Engine Controls: Notes

NOTE: All vehicles are equipped with either a Powertrain Control Module (PCM) or Vehicle Control Module (VCM) for engine control. Unless specifically stated, references to PCM also apply to VCM equipped vehicles. Bi-fuel vehicles are also equipped with an Fuel Injection Control Module (FICM). For FICM procedures, see FUEL INJECTION CONTROL MODULE under COMPUTERIZED ENGINE CONTROLS in CHEVY EXPRESS & SAVANA - BI-FUEL article.

NOTE: Some vehicles equipped with an electronically-controlled transmission also use a Transmission Control Module (TCM) for transmission control.
