This computer manages engine timing, fuel injection, and transmission control. When it fails, internal diagnostic trouble codes such as P0601 or P1696 often appear. This guide explains what the PCM does, where it is located, common failure symptoms, and the replacement process. You will also learn about factory service bulletin #18-037-05 and how a VIN-programmed replacement can simplify the repair.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 1997 Chrysler Town &amp; Country<\/h2>\n<p>The Powertrain Control Module (PCM) in your 1997 Chrysler Town &amp; Country (3.3L) is the main computer that manages engine timing, fuel delivery, transmission shift points, and emissions controls. When this module fails, it can cause a range of drivability problems. If you need a <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/chrysler-pcm-ecm-ecu-engine-computer\/town-country-engine-computers.html\">replacement PCM for the 1997 Chrysler Town &amp; Country<\/a>, it must be properly programmed to match your vehicle&#8217;s VIN and options.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>Replacing the PCM on this vehicle involves a book time of 0.6 hours for removal and installation, plus an additional 0.5 hours for the factory relearn procedure. The PCM is typically mounted in the engine compartment, often near the battery or on the driver-side fender well. Access may require removing the air intake duct or other components. After installation, the vehicle must undergo a relearn process to adapt the idle and shift strategies.<\/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\/1997-chrysler-town-country-pcm-location-diagram.webp\" alt=\"1997 Chrysler Town &amp; Country PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">PCM mounting location on the 1997 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 1997 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> both cables from battery, negative cable first.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> 2 screws holding Power Distribution Center (PDC) to bracket distributioncenter.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> heat shield from battery heatshieldbattery.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> nut and clamp holding battery to battery tray clampnut.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> battery from vehicle.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Rotate<\/b> PDC toward center of vehicle to remove from rear bracket.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Pull<\/b> PDC rearward to remove from front bracket.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> both way connectors.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> 3 screws holding PCM to fender.<\/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>Factory service bulletin #18-037-05 outlines flash programming failure recovery using the DRBIII\u00ae scan tool.

Even then, it will need to be flashed with your vehicle&#8217;s VIN and software, which requires a DRBIII\u00ae scan tool. A VIN-programmed replacement from Flagship One avoids these compatibility issues.<\/p>\n<h3>What does the 0.5-hour relearn procedure involve after replacing the PCM?<\/h3>\n<p>The factory relearn procedure allows the PCM to adapt to the engine&#8217;s idle air control and transmission shift adapts. It typically involves driving the vehicle through a specific cycle of idle, part-throttle, and wide-open-throttle conditions. The 0.5-hour book time covers this process.<\/p>\n<h3>My 1997 Town &amp; Country has code P1696. Does that mean the PCM is bad?<\/h3>\n<p>Code P1696 indicates a PCM failure (EEPROM write error). This is an internal module fault, not a sensor or wiring issue. The PCM must be replaced and properly programmed. A VIN-programmed unit from Flagship One will eliminate the need for dealer programming.<\/p>\n<\/div>\n<div class=\"info-section\">\n<p>If your 1997 Chrysler Town &amp; Country (3.3L) is showing internal PCM codes or drivability issues, you have two options: repair the original module or replace it with a refurbished unit. Given the complexity of flash programming and the availability of VIN-programmed replacements, many owners choose a direct swap to get back on the road quickly without dealer visits.<\/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\/chryslertcblack\/chryslertc-pcm-blackplug-1.jpg\" alt=\"Refurbished VIN-programmed PCM for the 1997 Chrysler Town &amp; Country\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">A refurbished, VIN-programmed replacement PCM for the 1997 Chrysler Town &amp; Country from Flagship One.<\/figcaption><\/figure>\n<p>Flagship One stocks a <a href=\"https:\/\/www.fs1inc.com\/1997-chrysler-town-country-3-3l-engine-computer-pcm-ecm-ecu-programmed.html\"><b>refurbished, VIN-programmed PCM for the 1997 Chrysler Town &amp; Country<\/b><\/a> with a lifetime warranty, free shipping and no core charge.
