When this module fails, multiple drivability issues typically emerge.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>The PCM is the central computer for the 3.6L engine and transmission<\/li>\n<li>Module failure may cause no-start conditions, stalling, or rough running<\/li>\n<li>Internal trouble codes P0601 and P0606 indicate memory problems<\/li>\n<li>Replacement requires VIN and mileage programming after installation<\/li>\n<li>Factory bulletin M38 addresses PCM reprogramming for this vehicle<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>If your 2012 Chrysler Town &amp; Country is experiencing starting problems, stalling, or unexpected transmission behavior, the Powertrain Control Module may be the culprit. This guide explains what the PCM does, common failure symptoms, and your replacement options. Whether you are diagnosing a check engine light or planning a repair, understanding the module&#8217;s role helps you make informed decisions about service. The information below covers factory procedures, programming requirements, and what to expect from a replacement unit.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2012 Chrysler Town &amp; Country<\/h2>\n<p>The Powertrain Control Module in your 2012 Chrysler Town &amp; Country functions as the primary computer for the 3.6L Pentastar V6 engine and automatic transmission. This unit integrates the engine control and transmission control functions into a single module, managing fuel delivery, idle speed, ignition timing, torque converter clutch operation, and emissions feedback systems. When the PCM encounters internal faults, it may store trouble codes and enter limp-home mode to prevent potential drivability damage. Replacement engine computers for the Town &amp; Country must be programmed with the original vehicle identification number and current odometer reading before they will allow the engine to start and operate normally.<\/p>\n<p>Flagship One keeps <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/chrysler-pcm-ecm-ecu-engine-computer\/town-country-engine-computers.html\">Chrysler Town &amp; Country replacement engine computers<\/a> in stock for exactly this failure pattern.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The Powertrain Control Module on the 2012 Chrysler Town &amp; Country is located in the electrical system category of factory service information. The removal and replacement procedure is categorized under electronic control modules. Book time for powertrain control module replacement is 0.6 hours, while the subsequent relearn procedure adds 0.5 additional hours. Access typically requires removing surrounding components to reach the module mounting location. After installation, the new module must be torqued to specification and connected securely before programming can begin.<\/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\/2012-chrysler-town-country-pcm-location-diagram.webp\" alt=\"2012 Chrysler Town &amp; Country PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">PCM mounting location on the 2012 Chrysler Town &amp; Country.<\/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 2012 Chrysler Town &amp; Country<\/h3>\n<ol style=\"margin:14px 0 6px 0;padding-left:26px\">\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the negative battery cable.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the PCM wire harness connector.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the fasteners and the PCM.<\/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\">All configurations<\/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\">All configurations<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.6 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\">All configurations<\/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\">All configurations<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.6 hr<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Programming Requirements After Replacement<\/h2>\n<p>After replacing the PCM on your 2012 Chrysler Town &amp; Country, the factory procedure requires programming with the original Vehicle Identification Number and the current vehicle mileage. This step is mandatory\u2014the engine will not start without this programming. If you obtain a VIN-programmed replacement unit from Flagship One, the module arrives pre-programmed with your vehicle&#8217;s specific information, eliminating this step at installation. The relearn procedure then synchronizes the new module with the engine and transmission sensors.<\/p>\n<p>Every <a href=\"https:\/\/www.fs1inc.com\/2012-chrysler-town-country-3-6l-ecm-engine-computer-pcm-ecu-programmed-plug-play.html\">VIN-programmed replacement unit<\/a> from Flagship One arrives with these steps already completed.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Symptoms of a Failing PCM<\/h2>\n<p>Common symptoms of PCM failure in this vehicle include a no-start condition where the engine cranks but will not run, intermittent stalling during acceleration or idle, and multiple misfire diagnostic trouble codes appearing without obvious mechanical cause. The scan tool may fail to communicate with the module entirely, or transmission gear shifting may become erratic or harsh. In some cases, the vehicle runs but exhibits poor fuel economy and elevated emissions. Internal module faults like <a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0601-internal-control-module-memory-checksum-error\/\">P0601<\/a> (internal memory check sum error) and <a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0606-control-module-processor\/\">P0606<\/a> (processor performance fault) often indicate the unit has experienced an electrical failure and requires replacement.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Module Trouble Codes on the 2012 Chrysler Town &amp; Country<\/h2>\n<p>The 2012 Chrysler Town &amp; Country may store internal PCM trouble codes that indicate module-level failures. These codes differ from typical sensor or circuit codes in that they point directly to the control module itself rather than an external component. Code P0601 represents an internal memory checksum failure, while P0606 indicates a processor performance problem. Both codes suggest the PCM has experienced an internal electrical fault and may require replacement.<\/p>\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\">Code<\/th>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Meaning<\/th>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Full Guide<\/th>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0601-internal-control-module-memory-checksum-error\/\" style=\"color:#0563C1;text-decoration:none;display:block;cursor:pointer\"><b>P0601<\/b><\/a><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0601-internal-control-module-memory-checksum-error\/\" style=\"color:#1a2b49;text-decoration:none;display:block;cursor:pointer\">Internal memory checksum error<\/a><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0601-internal-control-module-memory-checksum-error\/\" style=\"color:#0563C1\"><b><u>Full P0601 guide &rarr;<\/u><\/b><\/a><\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0606-control-module-processor\/\" style=\"color:#0563C1;text-decoration:none;display:block;cursor:pointer\"><b>P0606<\/b><\/a><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0606-control-module-processor\/\" style=\"color:#1a2b49;text-decoration:none;display:block;cursor:pointer\">Module processor failure<\/a><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0606-control-module-processor\/\" style=\"color:#0563C1\"><b><u>Full P0606 guide &rarr;<\/u><\/b><\/a><\/td>\n<\/tr>\n<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Factory Service Bulletins Worth Knowing<\/h2>\n<p>Factory service bulletin Rc-Im38-13, designated as Customer Satisfaction Notification M38, addresses reprogramming the Powertrain Control Module on certain vehicles.
