From the Diagnostic Bay: The Intermittent Stall Case
I remember a 2004 Dakota 3.7L that came into my shop a few years back. The owner was at his wit’s end. The truck would run fine for days, then suddenly stall at a stoplight and refuse to restart for 10 minutes. Other shops had replaced sensors and checked wiring, but the problem always returned. After connecting my scanner, I saw a stored history code: P0601 – Internal Control Module Memory Check Sum Error. This code is a dead giveaway. The ECM’s internal processor was failing intermittently. We installed a pre-programmed ECM just like this one, and the truck never had the issue again. It’s a classic failure mode for these vehicles, and a correctly configured module is the only reliable fix.
Is Your Dakota Showing These Signs of a Bad ECM?
- ✔ Persistent Check Engine Light (CEL) that won’t clear.
- ✔ Common diagnostic trouble codes (DTCs) such as P0601, P0606, or other internal processor faults.
- ✔ Unexplained stalling or engine cutting out while driving.
- ✔ A no-start or hard-starting condition, even with a good battery and starter.
- ✔ Poor or erratic automatic transmission shifting.
- ✔ Noticeable decrease in fuel economy.
- ✔ Communication errors with diagnostic scan tools.
DIY Installation: A Straightforward Guide
You don’t need to be a master mechanic to install this part. With basic hand tools, you can have your truck running right in under an hour. Our pre-programming makes this a simple component swap.

- Disconnect and Remove: Carefully unplug the main wiring harness connectors. They have locking tabs that need to be released. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed ECM into place. Securely plug in the wiring harness connectors, ensuring they click and lock.
