What the PCM Does in a 2019 Nissan Kicks
The powertrain control module (PCM) in the 2019 Nissan Kicks is the vehicle’s primary engine management computer. It receives data from sensors throughout the engine and drivetrain, then adjusts fuel delivery, ignition timing, variable valve timing, and transmission shift points to optimize performance, fuel economy, and emissions. The module also monitors system health and stores diagnostic trouble codes when it detects a fault. In the Kicks, the PCM is integrated with the engine control module (ECM) functions, so the terms are often used synonymously. This module is critical for the engine to run correctly; without it, the vehicle will not start or will run in a degraded limp-home mode. When the module fails internally, it can cause erratic behavior, no-start conditions, or trigger codes like P0605. If you need to replace it, you should consider replacement engine computers for the Kicks that are pre-programmed to match your vehicle’s VIN, which simplifies the installation process. The module’s location in the engine bay makes it accessible for replacement, but the factory programming steps after installation require specialized equipment or a trip to the dealer.
Where the PCM Is Located and What Replacement Involves
The PCM/ECM in the 2019 Nissan Kicks is typically mounted in the engine compartment, often near the battery or on the firewall. Access may require removing the air intake duct or other components to reach the module. The factory book time for removing and replacing the module is 1.1 hours. The procedure involves disconnecting the negative battery cable, unplugging the wiring harness connectors, and unbolting the module from its bracket. Care must be taken to avoid damaging the connectors or the module itself. After installation, the system requires a series of programming steps to synchronize the module with the vehicle’s security and engine management systems. No torque specifications are provided in the available data, but standard practice is to tighten mounting bolts securely without over-torquing.
| Operation | Configuration | Book Time |
|---|---|---|
| Powertrain Control Module R&R | All configurations | 1.1 hr |
| Powertrain Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module R&R | All configurations | 1.1 hr |
| Engine Control Module Reset | All configurations | 0.3 hr |
| Engine Control Module Relearn | All configurations | 0.5 hr |
Programming Requirements After Replacement
After replacing the PCM/ECM in the 2019 Nissan Kicks, the factory procedure requires a PCM relearn (0.5 hours), an ECM reset (0.3 hours), and an ECM relearn (0.5 hours). These steps are necessary to calibrate the module to the vehicle’s specific engine and transmission parameters, and to synchronize the immobilizer system. Without these steps, the engine may not start or may run poorly. Instead of performing these steps yourself, you can order a VIN-programmed replacement unit from Flagship One that arrives ready to install. Their units are pre-loaded with the correct software for your VIN, so the factory relearn and reset procedures are already completed. This saves you the labor time and the need for specialized diagnostic equipment. Simply install the module, reconnect the battery, and the vehicle should start and run normally.
Symptoms of a Failing PCM
When the PCM/ECM begins to fail in the 2019 Nissan Kicks, you may notice a variety of symptoms. The engine may crank but not start, or it may stall unexpectedly while driving. You might experience rough idling, misfires, or a noticeable loss of power. The check engine light will likely illuminate, and a scan tool may retrieve diagnostic trouble codes. One common trouble code is internal control module fault which indicates an internal processor error within the module itself. Other symptoms include erratic transmission shifting, poor fuel economy, or the vehicle entering a limp-home mode that limits speed and performance. In some cases, the scan tool may fail to communicate with the module entirely, suggesting a complete failure. These symptoms can also be caused by other issues like wiring problems or sensor failures, so proper diagnosis is essential before replacing the module.
