Have a failed, water-damaged, corrupted, or non-communicating GM E37 Engine Control Module (ECM)?

You send us your original E37 ECM, and we provide a compatible remanufactured E37 replacement. We transfer the applicable vehicle-specific data and configuration, professionally program and bench test the replacement, and return it ready for installation where supported.

YOU SEND YOUR ORIGINAL E37 — WE PROVIDE THE REMANUFACTURED ECM

No donor or replacement ECM required.

Lacorte Automotive supplies the compatible replacement, and every remanufactured E37 provided through this service includes our 3-Year Warranty.

SUPPORTED GM APPLICATIONS

Supported applications may include select:

• Chevrolet
• GMC
• Buick
• Pontiac
• Saturn
• Other GM applications equipped with the E37 ECM

Exact compatibility depends on the original GM service number, part number, hardware/software version, engine, model year, production date, and vehicle configuration.

If you're unsure, send us a clear photo of your original E37 label and VIN before ordering.

COMMON E37 ECM FAILURE SYMPTOMS

A failing E37 may potentially cause:

• Crank but no start
• Intermittent no-start
• Engine stalling
• Rough running or misfires
• Reduced engine power
• Limp mode
• No communication with ECM
• Intermittent ECM communication
• Injector or ignition-related faults
• Sensor circuit faults
• Throttle-related faults
• Multiple unrelated DTCs
• Internal ECM faults
• Corrupted software/data

Proper diagnosis is strongly recommended. Wiring, grounds, power supplies, sensors, injectors, ignition components, throttle components, fuel-system problems, and other vehicle systems can cause similar symptoms.
