2018 Dodge Charger PCM/ECM: Symptoms, Programming, Replacement
The Powertrain Control Module (PCM) in a 2018 Dodge Charger 5.7L manages engine and transmission operations, including fuel injection, ignition timing, and shift points. Failure of this module can cause no-start conditions, misfires, erratic shifting, and trigger diagnostic trouble code P0601.
Quick Summary
- PCM replacement book time is 0.6 hours, with an additional 0.5 hours for a relearn procedure.
- A new PCM must be programmed with the original VIN and mileage per factory procedure.
- Safety Recall U60 involves reprogramming the PCM on certain 2018 Charger models.
- Diagnostic trouble code P0601 indicates an internal PCM fault.
- Flagship One offers pre-programmed PCMs that eliminate the need for VIN/mileage programming.
If you own a 2018 Dodge Charger with the 5.7L engine and are experiencing drivability issues, the Powertrain Control Module (PCM) may be at fault. This module is the central computer that controls engine and transmission functions. This guide covers common symptoms of PCM failure, the replacement procedure with factory book times, and the critical programming step required after installing a new unit. You will also learn about a relevant safety recall and how pre-programmed replacement modules can simplify the repair.
What the PCM Does in a 2018 Dodge Charger
The PCM in your 2018 Dodge Charger 5.7L is the primary electronic controller for the powertrain. It processes sensor inputs to adjust fuel delivery, ignition timing, and transmission shift patterns. When the PCM fails, the vehicle may not start, run poorly, or set diagnostic trouble codes. For a reliable fix, you can choose from replacement PCMs for the Charger that are pre-programmed to match your vehicle’s VIN and mileage, saving you the factory-required programming step. Understanding the PCM’s role helps you diagnose issues accurately and avoid unnecessary part replacements.
Where the PCM Is Located and What Replacement Involves
The replacement procedure for the PCM on the 2018 Dodge Charger 5.7L is listed at 0.6 hours of book time for removal and installation. An additional 0.5 hours is required for a Powertrain Control Module Relearn after installation. If you are replacing the Engine Control Module (ECM), the book time is also 0.6 hours, with a 0.5-hour relearn or a 0.3-hour reset option. Factory notes specify that a new PCM must be programmed with the original Vehicle Identification Number (VIN) and mileage. Refer to the service manual section 08 – Electrical/8E – Electronic Control Modules for detailed programming instructions.
How to Reach the PCM on the 2018 Dodge Charger
- Disconnect and isolate the negative battery cable.
- Remove the cowl plenum cover/grille panel from over the wiper module.
- Remove the Powertrain Control Module (PCM) retaining bolt.
- Disconnect the PCM electrical connectors.
- Remove the PCM from the vehicle.
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 | All configurations | 0.6 hr |
| Engine Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module Reset | All configurations | 0.3 hr |
| Engine Control Module R&R | All configurations | 0.6 hr |
Programming Requirements After Replacement
Factory procedure for the 2018 Dodge Charger 5.7L requires that any new PCM be programmed with the original VIN and mileage before the vehicle can operate correctly. This step is critical for proper immobilizer function and emissions compliance. Flagship One provides a VIN-programmed replacement unit that arrives ready to install, so the dealer-level programming step is already completed. This eliminates the need for a separate programming session and gets your Charger back on the road faster.
Symptoms of a Failing PCM
A failing PCM in the 2018 Dodge Charger 5.7L often produces symptoms such as a no-start condition, intermittent stalling, rough idle, or misfire codes. You may also notice erratic transmission shifting, reduced fuel economy, or a check engine light that stays on. A common diagnostic code associated with internal PCM failure is internal control module fault P0601, which indicates a problem within the module itself. If the scan tool cannot communicate with the PCM, the module may have suffered a complete failure.
Module Trouble Codes on the 2018 Dodge Charger
The following module-internal trouble code is documented for the 2018 Dodge Charger 5.7L PCM. This code points to a fault within the control module itself rather than an external sensor or circuit.

Protecting the PCM in Your 2018 Dodge Charger
- Maintain a healthy charging system; voltage spikes from a failing alternator can damage the PCM.
- Keep battery and chassis grounds clean and tight to ensure stable module operation.
- Avoid jump-starting with incorrect polarity or using high-voltage boosters that can send surges.
- Address diagnostic trouble codes promptly before they lead to module damage.
- Inspect PCM connector seals for cracks or moisture intrusion, especially after engine bay cleaning.
Frequently Asked Questions
Can I replace the PCM in my 2018 Dodge Charger 5.7L myself?
Yes, if you have basic mechanical skills. The book time for removal and installation is 0.6 hours. However, a new PCM must be programmed with the VIN and mileage, which typically requires a dealer or specialized tool. A pre-programmed unit from Flagship One avoids that step.
What does the P0601 code mean on a 2018 Dodge Charger?
P0601 is an internal control module fault code. It indicates a problem within the PCM itself, such as a memory or processor error. This often requires module replacement rather than a simple repair.
Is Safety Recall U60 still active for my 2018 Charger?
Safety Recall U60 applies to Canadian vehicles and involves reprogramming the PCM. Check with a Dodge dealer using your VIN to see if the recall is still open and if your vehicle is included.
When your 2018 Dodge Charger 5.7L needs a PCM, you have two main options: have a dealer install a new module and perform the required VIN/mileage programming, or choose a refurbished replacement that is pre-programmed. The latter can save time and labor costs. Flagship One offers model-specific units that are ready to install, reducing downtime.
Flagship One stocks a refurbished, VIN-programmed PCM for the 2018 Dodge Charger with a lifetime warranty, free shipping and no core charge. The full Dodge Charger module lineup covers other engine configurations as well.
Final Thoughts
The PCM in your 2018 Dodge Charger 5.7L is a critical component that controls engine and transmission performance. Recognizing symptoms like no-start or code P0601 can lead to a timely repair. Whether you choose a dealer-installed new module or a pre-programmed replacement, ensure the VIN and mileage programming is handled correctly. Flagship One provides a convenient solution for a direct swap.
