When its software or circuitry fails, the vehicle may lose power, misfire, or stall, impacting drivability and safety.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>PCM located underhood on driver side inner fender panel.<\/li>\n<li>Replacement labor: 0.5 hours for relearn, 0.6 hours for R&amp;R.<\/li>\n<li>Engine module relearn: 0.5 hours.<\/li>\n<li>Engine module R&amp;R: 0.5 hours.<\/li>\n<li>Flagship One units are VIN\u2011programmed, eliminating post\u2011install programming.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>You might notice your 1993 Chrysler Town &amp; Country hesitating, stalling, or refusing to start. These symptoms can stem from a malfunctioning PCM, the brain that coordinates engine and transmission behavior. By understanding how the PCM works, where it sits, and what a replacement entails, you can assess whether a quick repair or a refurbished unit is right for your vehicle.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 1993 Chrysler Town &amp; Country<\/h2>\n<p>In the 1993 Chrysler Town &amp; Country, the PCM manages fuel injection timing, ignition events, and shift logic. Its failure can disrupt engine performance or prevent the vehicle from starting. <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/chrysler-pcm-ecm-ecu-engine-computer\/town-country-engine-computers.html\">replacement engine computers for the 1993 Chrysler Town &amp; Country<\/a> ensure that the new module can replicate the original settings and operate within the vehicle\u2019s control architecture.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The PCM is positioned under the hood on the driver side inner fender panel. To replace it, remove the panel cover, disconnect the harness, and slide the unit out. Reinstalling requires 0.5 hours for relearn and 0.6 hours for a full R&amp;R. After the unit is seated, reapply the harness and secure the cover.<\/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\/1993-chrysler-town-country-pcm-location-card-1.webp\" alt=\"1993 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 1993 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 1993 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>Remove<\/b> air cleaner.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Depress<\/b> tab on top of solenoid and slide the so- lenoid downward out of mounting bracket.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> idle air control motor 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\">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\">0.5 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 Flagship One PCM, no additional factory programming is needed because the unit arrives VIN\u2011programmed.
