Together they maintain smooth operation and comply with emission standards.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The PCM sits under the driver\u2019s seat, accessed by removing the lower dash panels. Replacing it requires the 0.5\u2011hour relearn procedure or a 0.6\u2011hour reset. The ECM is located in the engine bay, accessible after removing the air intake and battery covers. The 0.5\u2011hour relearn or 0.6\u2011hour reset applies there as well.<\/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\/1998-chrysler-town-country-pcm-location-diagram.webp\" alt=\"1998 Chrysler Town &amp; Country PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">PCM mounting location on the 1998 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 1998 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>After installing a new PCM, the factory procedure requires reprogramming with the vehicle\u2019s VIN and mileage.
