When the ECM fails, the vehicle may lose engine power, misfire, or refuse to start, and diagnostic trouble codes such as P0601 can appear.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>ECM relearn procedures typically require 0.5\u202fhours for a simple reset.<\/li>\n<li>Full removal and replacement generally takes about 0.6\u202fhours of labor.<\/li>\n<li>Factory service bulletins address speed control and sensor illumination issues.<\/li>\n<li>Two internal codes, P0601 and P0606, are documented for this model.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When the engine control module stops communicating correctly in a 2009 Chrysler Town &amp; Country, the vehicle can exhibit a range of drivability problems. This guide explains what the ECM does, where it lives, how technicians reset or replace it, and what you can expect after the work is completed. By the end, you will understand the key steps and why a properly programmed replacement matters for reliable operation.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2009 Chrysler Town &amp; Country<\/h2>\n<p>In the 2009 Chrysler Town &amp; Country, the Engine Control Module interprets sensor data to regulate fuel delivery, spark timing, and emissions. It also coordinates with the transmission control unit to ensure smooth shifting. A malfunction can trigger a loss of power or a check\u2011engine light, making timely service important. The module\u2019s role is central to engine performance, and a failure often requires a replacement or a relearn procedure. <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/chrysler-pcm-ecm-ecu-engine-computer\/town-country-engine-computers.html\">Town &amp; Country ECM replacement<\/a> helps restore full vehicle functionality.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The ECM is located within the engine compartment under the electronic control modules section, identified as part of the Electrical \u2022 8e category. Access typically involves disconnecting the battery, removing the module\u2019s mounting bolts, and unplugging the harnesses. The labor estimate for removal and installation is listed as 0.6\u202fhours, while a simple relearn operation is quoted at 0.5\u202fhours. Technicians should verify connector integrity and torque fasteners to factory specifications during reassembly.<\/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\/2009-chrysler-town-country-ecm-location-card-1.webp\" alt=\"2009 Chrysler Town &amp; Country PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">Typical PCM mounting area on the 2009 Chrysler Town &amp; Country (reference).<\/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 2009 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> and isolate negative battery cable.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the harness connector from the ECM.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the fastener and remove the ECM from the bracket.<\/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 installing a new ECM, the factory procedure calls for a Powertrain Control Module relearn, which takes about half an hour of labor.
