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&#8217;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.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2001 Chrysler Concorde<\/h2>\n<p>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&#8217;s identity. That is where <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/chrysler-pcm-ecm-ecu-engine-computer\/concorde-engine-computers.html\">replacement PCMs for the Chrysler Concorde<\/a> come into play, as they must be programmed with the original VIN and mileage to match the vehicle&#8217;s security and emissions systems.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>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&amp;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.<\/p>\n<figure style=\"margin:22px auto;text-align:center;max-width:720px\"><img decoding=\"async\" style=\"max-width:100%;height:auto;border:1px solid #e2e6ec;border-radius:8px\" src=\"https:\/\/www.fs1inc.com\/blog\/wp-content\/uploads\/2026\/07\/2001-chrysler-concorde-pcm-location-diagram.webp\" alt=\"2001 Chrysler Concorde PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">PCM mounting location on the 2001 Chrysler Concorde.<\/figcaption><\/figure>\n<div style=\"background:#f7f9fc;border:1px solid #e2e8f2;border-radius:10px;padding:18px 24px;margin:18px 0\">\n<h3 style='margin-top:0'>How to Reach the PCM on the 2001 Chrysler Concorde<\/h3>\n<ol style=\"margin:14px 0 6px 0;padding-left:26px\">\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> washer bottle filler neck.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> Transmission Control Module (TCM) reposition out of the way.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> PCM 2 40-way connector.<\/li>\n<\/ol>\n<p style='margin:10px 0 0 0'><em>Work with the ignition off, and treat the module as static-sensitive: avoid touching the connector pins at any point.<\/em><\/p>\n<\/div>\n<table style=\"width:100%;border-collapse:collapse;margin:18px 0;font-size:15px\">\n<tr>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Operation<\/th>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Configuration<\/th>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Book Time<\/th>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Powertrain Control Module Relearn<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">300M<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.5 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Powertrain Control Module Relearn<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Concorde<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.5 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Powertrain Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">300M<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.4 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Powertrain Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Concorde<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.4 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Engine Control Module Relearn<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">300M<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.5 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Engine Control Module Relearn<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Concorde<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.5 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Engine Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">300M<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.4 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Engine Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Concorde<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.4 hr<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Programming Requirements After Replacement<\/h2>\n<p>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&#8217;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 href=\"https:\/\/www.fs1inc.com\/2001-chrysler-concorde-2-7l-engine-computer-pcm-ecm-ecu-programmed.html\">a VIN-programmed replacement PCM<\/a> 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.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Symptoms of a Failing PCM<\/h2>\n<p>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 <a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0601-internal-control-module-memory-checksum-error\/\">internal memory checksum error P0601<\/a>, which indicates the module&#8217;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.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Module Trouble Codes on the 2001 Chrysler Concorde<\/h2>\n<p>The following trouble codes are stored internally within the PCM of your 2001 Chrysler Concorde 2.7L.

However, you will need a DRB scan tool or equivalent to program the new module with the VIN and mileage unless you purchase a pre-programmed unit. The relearn procedure adds 0.5 hours and may require a specific drive cycle.<\/p>\n<h3>What does trouble code P0601 mean on a 2001 Chrysler Concorde?<\/h3>\n<p>P0601 is an internal control module memory checksum error. It indicates that the PCM&#8217;s internal memory has corrupted data. This is a hardware fault inside the module itself, not a wiring or sensor issue. Replacement of the PCM is typically required to resolve this code.<\/p>\n<h3>Is the PCM the same as the ECM on this vehicle?<\/h3>\n<p>On the 2001 Chrysler Concorde 2.7L, the Powertrain Control Module (PCM) combines the functions of an engine control module (ECM) and transmission control module (TCM) into one unit. The terms are often used interchangeably in service literature, but the official name is PCM.<\/p>\n<\/div>\n<div class=\"info-section\">\n<p>When your 2001 Chrysler Concorde 2.7L needs a new PCM, you have two main options: have a dealer or shop install a blank module and program it using the DRB scan tool, or choose a pre-programmed replacement that arrives ready to install. The pre-programmed route saves the programming labor and the need for specialized equipment. For this model, the R&amp;R takes 0.4 hours and the relearn adds 0.5 hours, so a pre-programmed unit can reduce total downtime.<\/p>\n<figure style=\"margin:22px auto;text-align:center;max-width:720px\"><img decoding=\"async\" style=\"max-width:100%;height:auto;border:1px solid #e2e6ec;border-radius:8px\" src=\"https:\/\/www.fs1inc.com\/media\/wysiwyg\/googleshop\/chryslertcgray\/chryslertc-pcm-grayplug-1.jpg\" alt=\"Refurbished VIN-programmed PCM for the 2001 Chrysler Concorde\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">A refurbished, VIN-programmed replacement PCM for the 2001 Chrysler Concorde from Flagship One.<\/figcaption><\/figure>\n<p>Flagship One stocks a <a href=\"https:\/\/www.fs1inc.com\/2001-chrysler-concorde-2-7l-engine-computer-pcm-ecm-ecu-programmed.html\"><b>refurbished, VIN-programmed PCM for the 2001 Chrysler Concorde<\/b><\/a> with a lifetime warranty, free shipping and no core charge.
