IGNITION CONTROL MODULE, IGNITER. The ignition control module, also known as an igniter, is an electronic component of the gasoline engine ignition system responsible for controlling high-voltage spark generation through ignition coils. It processes signals from crankshaft and camshaft position sensors and switches the primary circuit of the ignition coil to produce a secondary high-voltage spark required for combustion. The unit may be integrated into the ignition coil assembly or installed as a separate module with heat-dissipating housing and power transistors. Failure symptoms include engine misfires, hard starting, reduced power, increased fuel consumption and ignition-related fault codes. Causes may involve overheating, transistor failure or connector corrosion. Our catalog includes genuine OEM ignition modules, quality aftermarket replacements and inspected used units tested for signal output and circuit integrity. Selection is based on VIN number, engine configuration and part number. Diagnostic reset may be required after installation. Timely replacement ensures reliable spark generation and stable engine performance.
