Is Your 2006 Chrysler, Dodge, or Magnum Running Rough?
A failing Engine Control Module (ECM) can be the source of countless frustrating and difficult-to-diagnose issues. If your 2006 Chrysler 300, Dodge Charger, or Dodge Magnum with the 3.5L engine is experiencing erratic behavior, poor performance, or won’t start at all, the ECM is a primary suspect. This critical component is the brain of your vehicle, controlling everything from fuel injection and ignition timing to transmission shifting and emissions. When it fails, the symptoms can be widespread and confusing, often leading to incorrect diagnoses and costly, unnecessary repairs.
From the Diagnostic Bay
We had a 2006 Dodge Magnum 3.5L towed in that was a real head-scratcher. The owner had replaced the battery, alternator, and even the fuel pump, but it still had an intermittent no-start condition and would occasionally stall while driving. Diagnostic codes were all over the place, pointing to communication errors between modules. After hours of chasing wires, we finally hooked up a scope to the CAN bus network at the ECM connector. We found the signal would drop out completely when the module got warm. A replacement, pre-programmed ECM solved all the issues instantly. It’s a classic case of how a faulty computer can mimic a dozen other problems.

Frequently Asked Questions
Is this ECM really plug and play?
Yes. We flash the module with the latest software from the manufacturer and program it using the VIN you provide during checkout. This ensures it communicates perfectly with your vehicle’s other modules, including the ignition and anti-theft system, right out of the box. All you need to do is install it.
Where is the ECM located on my 2006 Chrysler 300?
On the 2006 Chrysler 300, the Engine Control Module is typically located in the engine compartment on the right-hand (passenger) side, near the firewall. For the 2006 Dodge Charger and Magnum, it’s usually found on the left-hand (driver) side front of the engine compartment. Always disconnect the battery before attempting to remove or install the module.
What happens if I install an ECM that isn’t programmed to my VIN?
An unprogrammed ECM will not work correctly. The vehicle’s security system (immobilizer) will prevent the engine from starting because the VIN in the ECM will not match the VIN stored in the ignition key and other modules. This is why our pre-programming service is essential for a successful repair.
How can I be sure my ECM is the problem?
While the symptoms listed above are strong indicators of a failing 2006 Chrysler 300 ECM, it’s always best to have a professional diagnosis performed. A qualified technician can rule out other potential causes like wiring issues, sensor failures, or power supply problems to confirm the ECM is at fault before you order a replacement.
Do I need to send my old ECM back?
No core charge or return is required for this part. You can keep your old module or dispose of it responsibly.
