Ignition System: Description

All vehicles are equipped with a high energy ignition system capable of producing in excess of 40,000 volts. Systems include the C³ I system, DIS system and IDI system. Catera uses a simple DIS system which contains a coil pack which is directly controlled by the ECM. Camaro, Firebird and Corvette use a multiple-coil ignition system which utilizes 8 separate ignition coil/module assemblies mounted on the rocker covers. This system is also known as Coil-Near-Plug (CNP).
