The PCM is the central computer that controls engine timing, fuel delivery, and transmission shifting. Replacing it is a straightforward repair, but the new module must be programmed with your vehicle’s original VIN and mileage to function correctly. This guide explains what the PCM does, where it is located, the labor times involved, and what to expect during replacement. You will also learn about the factory service bulletin that applies to this model and how to avoid common pitfalls. Whether you plan to repair or replace the module, understanding the process helps you make an informed decision.
What the PCM Does in a 2001 Chrysler Concorde
The Powertrain Control Module (PCM) in your 2001 Chrysler Concorde 2.7L is the main engine and transmission computer. It receives input from sensors such as the crankshaft position sensor, throttle position sensor, and oxygen sensors, then adjusts fuel injection, ignition timing, and shift points accordingly. The PCM also monitors system health and stores diagnostic trouble codes when it detects a fault. Because the Concorde uses a drive-by-wire throttle and a four-speed automatic transmission, the PCM plays a critical role in smooth operation. When the module fails internally, it may lose communication with the scan tool, cause erratic shifting, or prevent the engine from starting. Replacing a faulty PCM restores proper control, but the new unit must be initialized with the vehicle’s identity. That is where replacement PCMs for the Chrysler Concorde come into play, as they must be programmed with the original VIN and mileage to match the vehicle’s security and emissions systems.
Where the PCM Is Located and What Replacement Involves
The PCM on the 2001 Chrysler Concorde 2.7L is typically mounted in the engine bay, often on the driver side near the strut tower or behind the battery. Access requires removing any covers or air intake ducting that may obstruct the module. According to labor guides, the removal and replacement (R&R) of the PCM is book-timed at 0.4 hours. After installation, a relearn procedure is necessary, which adds 0.5 hours of labor. The relearn process involves using a scan tool to initialize the module and may require a specific drive cycle to adapt the idle and fuel trims. Ensure the battery is fully charged before beginning, as low voltage can interrupt the programming sequence. The connector is keyed and should be inspected for corrosion or bent pins before reconnecting.
How to Reach the PCM on the 2001 Chrysler Concorde
- Remove washer bottle filler neck.
- Remove Transmission Control Module (TCM) reposition out of the way.
- Disconnect PCM 2 40-way connector.
Work with the ignition off, and treat the module as static-sensitive: avoid touching the connector pins at any point.

Programming Requirements After Replacement
After installing a new PCM in your 2001 Chrysler Concorde 2.7L, the factory procedure requires using a DRB scan tool to reprogram the module with the vehicle’s original identification number (VIN) and the original mileage. This step is critical for the immobilizer system and emissions compliance. Without this programming, the engine may not start or may run poorly. Flagship One supplies a VIN-programmed replacement PCM that arrives with the correct VIN and mileage already loaded, so the DRB scan tool step is already completed. You still need to perform the relearn procedure (0.5 hours) to allow the module to adapt to your specific engine and transmission, but the initial programming is done before shipping.
Symptoms of a Failing PCM
A failing PCM in the 2001 Chrysler Concorde 2.7L can produce a range of symptoms. The engine may crank but not start, or it may stall unexpectedly while driving. You might notice erratic transmission shifting, such as harsh engagement or failure to shift gears. The check engine light may illuminate with codes that do not clear, or the scan tool may fail to communicate with the module entirely. Misfire codes, fuel trim issues, or a no-spark condition can also point to PCM failure. One specific internal fault is internal memory checksum error P0601, which indicates the module’s internal memory has corrupted data. This code typically requires PCM replacement because the fault is inside the computer itself, not in an external sensor or wiring.
Module Trouble Codes on the 2001 Chrysler Concorde
The following trouble codes are stored internally within the PCM of your 2001 Chrysler Concorde 2.7L. These codes indicate internal module faults rather than external sensor or circuit issues.
