This is one of the most critical repairs you can make for your van’s long-term health.
Frequently Asked Questions
Is this module truly Plug & Play?
Yes, absolutely. We program the unit using the VIN you provide during checkout. This ensures it is fully compatible with your vehicle’s specific configuration. Once you receive it, you can install it directly without any need for a dealer or specialized tools for programming.
How do I provide my VIN and mileage?
After you place your order, we will contact you for your vehicle’s VIN and current mileage. This information is crucial for us to program the module correctly before shipping it to you.
Will this fix my check engine light?
This module is designed to correct issues that trigger fault codes related to the ECM itself, such as internal processor errors (e.g., P0601). If the check engine light is caused by a failing ECM, this part will resolve it. However, if the light is on due to another faulty sensor or component, that issue will still need to be addressed separately.
Where is the ECM located on my 2003 Voyager?
On the 2003 Chrysler Voyager, the Engine Control Module is typically located in the engine bay, mounted to the driver’s side (LH) inner fender well. It’s a silver metal box with three large electrical connectors.
What if my original part number isn’t an exact match?
This module is a direct replacement for a range of part numbers, including 04748312AD, 04748312AE, 04748312AF, and others listed in the description. As long as your vehicle is a 2003 Caravan or Voyager with the 2.4L engine, this programmed 2003 Chrysler Voyager ECM will be the correct fit.
