Is Your 2012 Dodge 1500 Running Rough? The ECM Might Be the Culprit.
If your 2012 Dodge 1500 or Jeep Liberty with the 3.7L engine is suffering from perplexing issues like stalling, poor fuel economy, a persistent check engine light, or a complete no-start condition, the root cause is often a failing Engine Control Module (ECM).

From the Diagnostic Bay
We had a 2012 Dodge 1500 come into the shop with a classic case of “parts cannon” diagnostics. The owner had replaced the throttle body, all the ignition coils, and the crankshaft position sensor, but the truck still had an erratic idle and would randomly stall at red lights. The check engine light was on with a confusing mix of codes. After confirming power and ground at the ECM connector, we suspected the main computer. We installed a pre-programmed 2012 Dodge 1500 ECM, and the truck immediately fired up and idled perfectly. It was a powerful reminder that sometimes the issue lies with the component controlling everything else.

Frequently Asked Questions
What does “Plug & Play” actually mean for this ECM?
Plug & Play means this module comes pre-programmed with your vehicle’s specific VIN and security information. You do not need to take it to a dealership or mechanic for additional programming. You can install it yourself by disconnecting the battery, swapping the old module for this new one, and reconnecting the battery.
Will this fix my transmission shifting problems?
In many cases, yes. The ECM works in conjunction with the transmission control module (TCM) to regulate shifting. If the ECM is sending faulty data, it can cause erratic shifting, delayed engagement, or other transmission issues. A new, correctly functioning ECM can resolve these communication-based problems.
How do I provide my VIN for programming?
You will be prompted to enter your vehicle’s 17-digit VIN during the checkout process. This step is critical to ensure we can program the module correctly for your specific vehicle configuration before shipping it to you.
Is this part compatible with my 2012 Jeep Liberty?
Yes, this electronic control module is compatible with the 2012 Jeep Liberty as long as it is equipped with the 3.7L engine. It serves as a direct replacement for the factory module in that application as well.
What tools are required for installation?
Installation is typically straightforward and requires basic hand tools. You will likely need a socket set (often 8mm or 10mm) to disconnect the battery terminal and unbolt the module’s mounting brackets and electrical connectors. No specialized electronic tools are needed.
