Whether you are diagnosing a no-start condition or planning a replacement, understanding these procedures helps ensure a successful repair. The information covers everything from locating the module to the critical programming steps needed after installation.
What the PCM Does in a 2013 Dodge Avenger
The Powertrain Control Module in your 2013 Dodge Avenger serves as the brain of the powertrain, managing engine combustion, transmission shift points, and emissions system operation. This computer receives input from dozens of sensors throughout the engine and transmission, then adjusts fuel delivery, ignition timing, and shift schedules in real time to maintain smooth operation and meet federal emissions standards. For the Dodge Avenger replacement engine computers specifically, the module integrates functions that older vehicles split between separate Engine Control Module and Transmission Control Unit computers. When this module experiences internal faults, it may store trouble codes that prevent normal operation or cause the vehicle to fail to start entirely.
Where the PCM Is Located and What Replacement Involves
The Powertrain Control Module in your 2013 Dodge Avenger is located at the lower most forward stud, where the ground strap (3) must be disconnected during replacement. Book time for PCM replacement on the 2.4L engine is 0.5 hours, with an additional 0.5 hour for relearn procedures after installation. The factory caution requires turning the ignition key to the OFF position and disconnecting the battery negative cable before unplugging any electrical connectors to avoid voltage spike damage to the module. When installing the new unit, ensure the ground strap is cleaned and securely attached to the specified stud. After mechanical installation, the relearn procedure must be performed to allow the new module to adapt to your vehicle’s specific engine characteristics.
How to Reach the PCM on the 2013 Dodge Avenger
- Disconnect the.
- Disconnect the Powertrain.
- Remove the three nuts.
Work with the ignition off, and treat the module as static-sensitive: avoid touching the connector pins at any point.
| Operation | Configuration | Book Time |
|---|---|---|
| Powertrain Control Module Relearn | All configurations | 0.5 hr |
| Powertrain Control Module R&R | 2.4L | 0.5 hr |
| Powertrain Control Module R&R | 3.6L | 0.3 hr |
| Engine Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module R&R | 2.4L | 0.5 hr |
| Engine Control Module R&R | 3.6L | 0.3 hr |
Programming Requirements After Replacement
After installing a new Powertrain Control Module in your 2013 Dodge Avenger, the factory procedure requires using a scan tool to reprogram the module with the original vehicle identification number (VIN) and the original mileage reading. If this step is not performed, a Diagnostic Trouble Code will set and the vehicle may not run properly. This programming step is critical because the module must be matched to your specific vehicle for proper operation. Flagship One units arrive as a VIN-programmed replacement unit, meaning the original VIN and mileage are pre-loaded at the factory, eliminating the need for this post-install programming step when using one of their units.
Symptoms of a Failing PCM
When the Powertrain Control Module fails on a 2013 Dodge Avenger, several symptoms commonly appear. The vehicle may refuse to start entirely, or it could start and then stall unexpectedly as the module loses the ability to maintain proper fuel and ignition functions. Misfire codes such as P0300 through P0304 may appear as the module fails to control combustion properly. In some cases, the scan tool cannot communicate with the module at all, indicating a dead or failed electronic control unit. Transmission shifting problems may also occur because the PCM controls shift points in addition to engine management. If your vehicle displays internal memory checksum fault along with these symptoms, the module has detected an internal fault that typically requires replacement rather than repair.
Module Trouble Codes on the 2013 Dodge Avenger
The 2013 Dodge Avenger may store module-internal trouble codes indicating specific internal failures within the Powertrain Control Module. These codes differ from regular diagnostic trouble codes in that they point directly to a failed component within the module itself rather than a fault in external sensors or wiring. Code P0601 indicates a checksum fault in the internal memory, while P0606 indicates a processor fault within the module. When these codes are present, replacement of the Powertrain Control Module is typically required.

Frequently Asked Questions
Will a used PCM from a salvage yard work in my 2013 Dodge Avenger?
A used PCM requires programming with your vehicle’s specific VIN and mileage using a dealer scan tool. Without this step, a DTC will set and the vehicle may not run. Additionally, you cannot verify the internal condition of a used module, making failure a real possibility.
Can I replace the PCM myself on a 2013 Dodge Avenger?
Technically skilled DIY mechanics can perform the replacement using the book time of 0.5 hours for R&R on the 2.4L engine. However, you will need a scan tool for the relearn procedure, and if installing a non-VIN-programmed unit, you will need dealer-level software access for VIN programming.
What happens if I don’t program the VIN into a new PCM?
The module will set a Diagnostic Trouble Code and may prevent the vehicle from starting or running properly. The factory requires VIN and mileage programming to ensure the module matches your specific vehicle’s emissions certification and odometer records.
