What the PCM Does in a 2016 Dodge Durango
The powertrain control module on your 2016 Dodge Durango acts as the central nervous system for the engine and automatic transmission. It processes input from the mass airflow sensor, crankshaft position sensor, throttle position sensor, and dozens of other signals to calculate fuel delivery, spark advance, and transmission shift schedules in real time. The 3.6L Pentastar V6 in the Durango relies heavily on this module to meet emissions standards and maintain driveability across varying loads and speeds. Because the module also participates in the vehicle bus network, it shares critical data with the ABS controller and other systems. When internal circuitry within the PCM fails, the module can no longer reliably execute these calculations, leading to drivability complaints or a no-start condition. Accessing the replacement engine computers for the Dodge Durango requires removing the unit from its bracket at the power distribution center.
Where the PCM Is Located and What Replacement Involves
The powertrain control module on the 2016 Dodge Durango with the 3.6L engine is secured to a mounting bracket that is co-located with the power distribution center. Removing the old unit involves disconnecting the electrical connectors, then lifting the module free from bracket position two. Installing the new module reverses this process: the replacement is positioned onto the bracket in the same location and reconnected. The book time for R&R alone is 0.6 hours, while positioning the new unit adds another 0.6 hours. After mechanical installation, a relearn procedure of 0.5 hours is typically needed, and if the ECM requires a separate reset, that is an additional 0.3 hours on top of that. Use care when disconnecting battery power before beginning the swap to avoid voltage spikes that could damage sensitive circuitry.
How to Reach the PCM on the 2016 Dodge Durango
- Disconnect the ABS CAB (controller) temporarily when replacing the PCM.
- Disconnect and isolate the negative battery cable.
- Remove the pressurized coolant bottle.
- Unplug the connectors from the PCM.
- Remove the PCM retaining screws.
- Position the ground strap aside.
- Remove the PCM from the mounting bracket located on the PDC.
Work with the ignition off, and treat the module as static-sensitive: avoid touching the connector pins at any point.

| 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
The factory procedure requires that after the powertrain control module is installed on the 2016 Dodge Durango, a diagnostic scan tool must be used to write the original vehicle identification number and recorded mileage into the replacement unit. This step is not optional; omitting it may cause a diagnostic trouble code to set and could disrupt communication with other modules on the bus network. Chrysler also recommends temporarily disconnecting the ABS controller during the replacement to prevent VIN broadcast conflicts. When you choose a VIN-programmed replacement unit from Flagship One, the module arrives already loaded with your VIN and mileage data, eliminating the post-installation reprogramming step that the factory specifies for new units.
Symptoms of a Failing PCM
On a 2016 Dodge Durango equipped with the 3.6L engine, a failing powertrain control module commonly produces a no-start condition or intermittent stalling that leaves the engine running rough at idle. Drivers often report that the engine stalls at low speeds or when coming to a stop, and the check engine light may illuminate with codes that seem to point everywhere. Scan tools may show no communication with the module, or multiple misfire and transmission shift quality complaints can appear simultaneously. The P0601 code, which indicates internal memory checksum failure within the module, is a documented fault for this vehicle and points directly to PCM internal circuitry rather than an external sensor problem. Other symptoms may include poor fuel economy, unresponsiveness from the throttle, and transmission engagement delays that feel unrelated to the transmission itself.
Module Trouble Codes on the 2016 Dodge Durango
The 2016 Dodge Durango covered here has documented module-internal diagnostic trouble codes recorded. These codes originate within the powertrain control module itself and indicate internal electronic faults rather than wiring or sensor failures elsewhere in the engine management system.

Common symptoms include a no-start condition, intermittent stalling, rough idle, unresponsiveness from the throttle, check engine light illumination, and in some cases complete loss of communication with a scan tool. Diagnostic codes such as P0601 or P0606 may appear, indicating internal module faults.
Do I need to reprogram the PCM after replacing it on my 2016 Dodge Durango?
Yes. The factory requires that the new PCM be programmed with the original VIN and the vehicle’s current mileage using a diagnostic scan tool. Units from Flagship One arrive pre-programmed with the correct VIN, which satisfies this requirement and reduces post-installation labor.
Why did my 2016 Dodge Durango set code P0601 after PCM replacement?
Code P0601 indicates an internal memory checksum error within the control module. If the replacement unit was not properly programmed with the correct VIN and mileage, or if the module itself has an undetected internal fault, the code may persist. Reprogramming the unit and verifying communication on the bus network should resolve it.
Deciding between repair and replacement for your 2016 Dodge Durango powertrain control module depends on the specific fault, the module’s physical condition, and your repair timeline.
