Is Your 2002 Jeep Liberty Running Rough?
If you’re dealing with frustrating issues like stalling, poor acceleration, a persistent check engine light, or erratic engine behavior, a failing Engine Control Module (ECM) is often the culprit.

Expert Insight: The Intermittent Stall Mystery
We once worked with a customer whose 2002 Liberty had an infuriating intermittent stalling problem. It would die at stoplights without warning, but then start right back up. Multiple shops had replaced sensors and fuel system components to no avail. The issue was heat-related; as the original ECM warmed up, an internal solder joint would fail, cutting power. A visual inspection revealed nothing. By replacing the module with a quality-tested and properly programmed unit like this 2002 Jeep Liberty ECM 56041606AB, the problem was solved permanently. Sometimes, the most complex-seeming issues have a straightforward electronic solution.
Frequently Asked Questions
Is this engine computer really ‘Plug and Play’?
Yes. We use the Vehicle Identification Number (VIN) you provide during checkout to program the module specifically for your Jeep. This ensures that it communicates correctly with your vehicle’s security system and other modules right out of the box. No further programming or flashing is needed.
What information do you need from me?
To ensure perfect programming, we require your vehicle’s 17-digit VIN and the current mileage. You can typically find the VIN on your driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
Will this fix my Check Engine Light?
If the check engine light is caused by an internal failure of the ECM (such as a P0601 code), this replacement will resolve the issue. After installation, it’s always a good practice to clear any stored codes with a standard OBD2 scanner. If other vehicle faults exist, the light may remain on for those separate issues.
How can I be sure this is the right part for my Jeep?
This module is specifically for the 2002 Jeep Liberty equipped with the 3.7L engine and an automatic transmission. The surest way to confirm is to match the part number on your existing ECM to one of the compatible numbers listed: 56041606AB, 56041606AD, 56041606AG, or 56041606AH.
Do I need to send my old computer (core) back?
This purchase does not require you to return your original module. There is no core charge or need to send your old part back to us, simplifying the repair process for you.
