From the Technician’s Bench: We once had a customer with a 2006 Grand Cherokee that would stall randomly at traffic lights. They had replaced sensors and checked fuel pressure with no luck. The issue was an intermittent failure within the original ECM, causing it to lose communication. Installing a properly programmed 2005-2006 Jeep Grand Cherokee 3.7L ECM like this one solved the problem instantly. A pro-tip: Always clean your battery terminals and check the main engine ground strap during installation. A solid connection is critical for the health of your new computer.
Frequently Asked Questions
Is this ECM really plug and play?
Yes, absolutely. We program the unit with the specific VIN and mileage you provide during checkout. This ensures it communicates perfectly with your Jeep’s existing modules and keys, requiring no additional programming on your end.
Where is the ECM located on my 2005-2006 Grand Cherokee?
You can find the Electronic Control Module (ECM) in the engine compartment, located on the right-hand (passenger) side, towards the rear near the firewall.
Do I need to send my old computer back?
No, there is no core charge or requirement to return your old module. You can keep it or dispose of it as you see fit.
How do I know for sure that my ECM is the problem?
While a professional diagnosis is always best, the symptoms listed aboveโespecially intermittent stalling, no-start conditions, and internal module fault codes like P0601โare strong indicators of a failing ECM. If other components like sensors and fuel delivery have been ruled out, the ECM is the next logical step.
Will this fix my immobilizer or security key issues?
Yes. Because we program the module to your vehicle’s VIN, it will correctly recognize your existing keys and security system, allowing the vehicle to start and run properly.
What if my original part number isn’t an exact match to 05094898AB?
No problem. This module is a compatible replacement for a full range of part numbers. As long as your vehicle is a 2005-2006 Grand Cherokee with the 3.7L engine and 4×4, and your original part number is on our compatibility list, this unit will work perfectly.
