Replace your failed engine computer with an OEM 2011 Jeep Patriot / Compass 2.4L PCM (also called an ECM or ECU), programmed to your vehicle before it ships.

This module is a direct replacement for units carrying service number 05150542AE, generic number 05150542AE. Every unit is refurbished, bench-tested against OEM specification, and flashed with the latest manufacturer software.

Also replaces: P05150542AE

Check your transmission type before ordering

Patriot and Compass share this module, but the calibration differs between CVT and manual transmission vehicles, and between two wheel drive and four wheel drive. Read the service number from the label on your existing module, or send us your VIN and we will confirm which unit your vehicle needs.

No core charge, and no core to send back

Several suppliers of these modules only offer a repair service, where you post your own unit in and wait days for it to come back. Others require a core exchange before the warranty becomes active. We do neither. Your module ships programmed and ready, there is no core charge and nothing to return, and the lifetime warranty starts the day it ships.

Why these modules must be programmed

These vehicles use the Sentry Key anti-theft system. The engine computer, keys and immobiliser have to be registered to each other or the engine will crank without starting. We programme the module to your VIN before dispatch, so your existing keys work on installation.

What you receive

• Programmed to your VIN before dispatch, so it installs plug and play
• Bench-tested by our technicians before it leaves us
• Lifetime warranty for as long as you own the vehicle
• Free US shipping, typically delivered in 2-4 business days
• No core charge, no core return required

Common symptoms of a failed Patriot / Compass PCM

• Engine cranks but will not start
• Misfire or faulty ignition coil codes that persist after replacing coils
• Alternator not charging the battery
• Check engine light or limp mode
• No communication with a scan tool

Before you order

Enter your 17-character VIN at checkout, and read the service number from the label on your existing module if you can. If unsure, call 516-494-7838 and a technician will confirm fitment.
