# Glow Plug Control Modules (GPCM)

Need a glow plug control module? Match the GPCM to the engine and preheat system instead of relying on a fault-code description.

Provide clear photos of the module case, label and connectors. Share engine and vehicle details, known trouble codes and whether power supply and harness faults have been checked.

## Replacement and programming questions

Confirm controller variants and electrical configuration before purchasing a substitute.

Compare the original hardware number, programming requirements and engine application with the product details. If you're unsure, send DCT the module label and we'll help you review available options.
