SUPPORTED GM APPLICATIONS

Supported applications may include select:

• Chevrolet
• GMC
• Buick
• Cadillac
• Other GM applications equipped with the E39 ECM

Compatibility is determined by your original GM service number, part number, hardware/software, engine, vehicle configuration, and production information.

If you're unsure, send us a clear photo of your original E39 label and VIN before ordering.

COMMON E39 ECM FAILURE SYMPTOMS

A failing E39 ECM may potentially cause:

• Crank but no start
• Intermittent no-start
• Engine stalling
