2019 Dodge Charger PCM: Replacement, Programming & Fault Codes
The Powertrain Control Module (PCM) in your 2019 Dodge Charger 3.6L is the central computer managing engine operation, transmission shifting, and fuel delivery. When internal memory corruption occurs (P0601), the module can lose calibration data, causing drivability problems or no-start conditions.
Quick Summary
- P0601 indicates internal memory checksum failure within the PCM itself
- PCM replacement requires VIN programming with the original vehicle mileage
- Book time for PCM R&R on this vehicle is 0.6 hours
- A new PCM must be programmed at the dealer or by a qualified tuning shop
- Flagship One units ship pre-programmed with your VIN, eliminating dealer programming delays
If your 2019 Dodge Charger has stored trouble code P0601, you are likely facing a failing Powertrain Control Module. This internal fault means the PCM’s memory has corrupted and can no longer reliably control engine and transmission functions. This guide explains what the PCM does in your Charger, common failure symptoms, replacement procedures, and programming requirements so you can make informed repair decisions.
What the PCM Does in a 2019 Dodge Charger
The Powertrain Control Module serves as the brain of your 2019 Dodge Charger’s powertrain. It processes inputs from dozens of sensors throughout the engine and transmission, then controls fuel injection, ignition timing, variable valve timing, and automatic transmission shift points. In the 3.6L Pentastar V6, the PCM also manages the MDS (Multi-Displacement System) that deactivates four cylinders for improved fuel economy during light-load driving. When this module fails internally, it loses the ability to execute these critical functions reliably, potentially leaving you stranded or causing drivability issues that affect safe operation of your vehicle.
Flagship One keeps Dodge Charger replacement engine computers in stock for exactly this failure pattern.
Where the PCM Is Located and What Replacement Involves
The PCM on a 2019 Dodge Charger 3.6L is located in the engine compartment, typically mounted on the left front fender well area. Access requires removing the air intake assembly and fender trim panel. The replacement procedure (R&R) books at 0.6 hours according to standard labor guides. After physically installing the new module, the technician must connect a scan tool to perform a PCM relearn procedure, which books an additional 0.5 hours. All electrical connectors must be properly seated and torqued to specification to prevent future moisture intrusion or loose-connection faults.
How to Reach the PCM on the 2019 Dodge Charger
- Disconnect and isolate the negative battery cable.
- Remove the hood ajar switch.
- Remove the Powertrain Control Module (PCM) fastener.
- Disconnect the PCM wire harness 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 |
Symptoms of a Failing PCM
When the PCM on your 2019 Dodge Charger develops an internal fault like P0601, you may experience no-start conditions where the engine cranks but fails to fire. Stalling after startup is common, particularly when the PCM loses its calibration memory while driving. Misfire codes (P0300-P0305) often accompany PCM failure as the module cannot properly control fuel delivery or ignition timing. In some cases, the scan tool may not communicate with the PCM at all, or gear-shifting becomes erratic as the transmission control portion of the module degrades. If your Charger displays any of these symptoms alongside a internal memory checksum fault, the PCM is the likely culprit.
Module Trouble Codes on the 2019 Dodge Charger
The following table documents the module-internal trouble code specifically flagged for this 2019 Dodge Charger 3.6L vehicle. This code indicates a factory-level fault within the PCM itself rather than a sensor or wiring issue.

Protecting the PCM in Your 2019 Dodge Charger
- Maintain your vehicle’s charging system—weak or fluctuating voltage can stress the PCM over time
- Keep all PCM connectors and ground points clean and corrosion-free
- Avoid jump-starting from another vehicle when possible, as voltage spikes can damage sensitive electronics
- Address any stored trouble codes promptly rather than clearing them and ignoring recurring issues
- Inspect and replace worn engine harness components that could introduce voltage anomalies
Frequently Asked Questions
Can I replace the PCM on my 2019 Dodge Charger with a used unit from a junkyard?
A used PCM will require dealer-level VIN programming to work in your vehicle, and you have no way to verify its internal health. A junkyard unit may have the same P0601 failure waiting to happen.
Will my 2019 Dodge Charger run after PCM replacement without programming?
No. The new PCM must be programmed with your VIN and mileage before the engine will start. Without this step, the module will not allow fuel injection or ignition to engage.
What does code P0601 mean for my Charger’s long-term outlook?
P0601 indicates the PCM has detected internal memory corruption. This is a hardware-level failure—the module cannot be repaired by clearing codes or updating software and must be replaced.
When your 2019 Dodge Charger needs a PCM, you have two primary paths: repair the existing module if a qualified electronics repair shop can address the internal failure, or install a replacement unit. A quality replacement PCM from Flagship One arrives VIN-programmed to your vehicle, saving you the dealer programming wait and expense. Either option restores proper engine management, but the pre-programmed replacement eliminates a critical post-install step.
Flagship One stocks a refurbished, VIN-programmed PCM for the 2019 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 P0601 code in your 2019 Dodge Charger signals a failed Powertrain Control Module that requires replacement. Whether you choose repair or replacement, ensure the new module is properly programmed with your VIN and mileage. A functioning PCM restores the complete management of your 3.6L engine and transmission, returning your Charger to reliable operation.
