98062002 Used GM 6.6L Duramax Glow Plug Control Module (GPCM)

This used GM 98062002 Glow Plug Control Module (GPCM) is designed for compatible Chevrolet and GMC vehicles equipped with the 6.6L Duramax turbocharged diesel engine.

The glow plug control module manages the operation of the engine’s glow plug system, helping provide the heat necessary for reliable diesel engine starting, particularly during cold-weather operation.

Unlike the main engine control module (ECM), the GPCM is dedicated to controlling and monitoring glow plug operation. It communicates with the vehicle’s electronic engine management system to coordinate glow plug activation based on engine operating conditions.

A malfunctioning glow plug control module can contribute to extended cranking, difficult cold starts, glow plug-related diagnostic trouble codes, and reduced starting performance in colder temperatures.

For commercial fleet operators and diesel repair facilities maintaining Chevrolet and GMC diesel vehicles, replacing a faulty GPCM can help restore proper cold-start operation without replacing the entire engine control system.

This tested used GM 98062002 glow plug controller provides a cost-effective alternative to purchasing a new replacement module.

Important Compatibility Note: GM used different glow plug control modules across Duramax engine generations. Verify the original part number, vehicle VIN, engine RPO code, and electrical connector configuration before purchasing.
