Is Your 2009 Chrysler, Dodge, or Jeep Running Poorly?
Dealing with a vehicle that stalls, misfires, or refuses to start can be incredibly frustrating. If your 2009 Chrysler Aspen, Dodge Durango, Dodge Ram 1500, Jeep Commander, or Grand Cherokee with the 5.7L Hemi engine is throwing confusing check engine light codes, experiencing erratic behavior, or suffering from a sudden drop in performance, the root cause is often a failing Engine Control Module (ECM). The ECM is the brain of your vehicle’s engine, and when it malfunctions, it can create a cascade of problems that are difficult to diagnose. Don’t let a faulty computer keep you off the road. This is your direct, reliable solution.
The Perfect Solution: A Plug-and-Play 2009 Aspen Engine Computer
Forget about expensive dealership visits, towing fees, and the hassle of programming a new module. This replacement engine computer, part number 68059431AA, arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN) and mileage. This means the critical immobilizer (anti-theft) data and other vehicle-specific parameters are already loaded. The installation process is straightforward: simply disconnect the battery, swap the old module with this new one, reconnect the battery, and start your engine. It’s a true plug-and-play fix designed to get you back on the road with confidence and minimal downtime.
From the Diagnostic Bay
We had a 2009 Grand Cherokee 5.7L in the shop that was a real head-scratcher. The customer complained of an intermittent no-start condition with no check engine light. We’d check for fuel, spark, and compression, and everything would test fine. The vehicle would then start and run perfectly for days. After checking every wire and sensor we could think of, we finally hooked up a scope to the main data bus lines going to the ECM. We discovered that during the no-start events, the ECM was simply not communicating—it was completely dead. A quick swap with a pre-programmed module like this one solved the problem instantly. The internal circuitry of the original ECM was failing intermittently, a common issue as these units age.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) that won’t clear.
- ✔ Engine stalling, stuttering, or running rough for no apparent reason.
- ✔ Complete no-start or intermittent starting problems.
- ✔ Noticeable decrease in fuel efficiency and engine power.
- ✔ Inconsistent or harsh automatic transmission shifting.
- ✔ Communication error codes (U-codes) stored in the system.
- ✔ Cooling fans running constantly or not at all.

Frequently Asked Questions
Is this engine computer really “plug and play”?
Yes. We program the module with the VIN you provide during checkout. This process loads all the necessary software and security information, allowing the module to work with your vehicle’s existing keys and systems without any additional programming required.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
What is the difference between an ECM, ECU, and PCM?
ECM (Engine Control Module) and ECU (Engine Control Unit) are often used interchangeably to describe the computer that controls the engine. PCM (Powertrain Control Module) is a term for a more integrated unit that controls both the engine and the transmission. For this specific vehicle application, the terms are generally synonymous.
Do I need to perform a “relearn” procedure after installation?
In most cases, no special relearn procedure is required. After installing the new ECM and reconnecting the battery, the vehicle may idle slightly differently for the first few minutes as it adjusts. Simply driving the vehicle normally for 15-20 minutes will allow it to complete any internal adjustments.
How can I be sure my original ECM is the problem?
While the symptoms listed are strong indicators of ECM failure, it’s always best to have a qualified mechanic perform a full diagnostic. This includes checking for proper power and ground at the ECM connector and verifying the integrity of the vehicle’s wiring harness to rule out other potential causes.
