Failure of either can trigger loss of power, erratic shifting, or diagnostic trouble codes such as P0601 and P0606.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>Relearn procedures typically require between 0.3 and 0.6 labor hours.<\/li>\n<li>A new PCM must be programmed with the original VIN and mileage.<\/li>\n<li>Factory cautions advise confirming VIN and software level before diagnosing PCM issues.<\/li>\n<li>Service bulletins U60 address required PCM reprogramming for safety recalls.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When a 2018 Dodge Challenger experiences powertrain glitches, the underlying cause often relates to the PCM or ECM. Understanding how these modules function and what steps are needed after replacement can help you avoid prolonged downtime. This guide explains the relearn processes, programming requirements, and practical tips so you can make an informed decision about repair or replacement.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2018 Dodge Challenger<\/h2>\n<p>The PCM in the 2018 Dodge Challenger controls fuel injection, ignition timing, and transmission shift strategy, while the ECM focuses on engine\u2011specific parameters. Together they ensure smooth acceleration and emissions compliance. Proper operation is essential for performance and fuel efficiency, and any disruption may lead to drivability problems. The vehicle may require a <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/dodge-pcm-ecm-ecu-engine-computer\/challenger-engine-computers.html\">replacement PCM for 2018 Challenger<\/a> during major service events.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The PCM and ECM are mounted within the engine compartment, accessible after removing the intake duct and battery connector. Replacing the unit typically involves about 0.6 labor hours for removal and reinstall, plus an additional 0.5 hours for a PCM relearn or ECM reset, depending on the specific task. No torque specifications are provided in the source material, so standard fastener tightening practices apply.<\/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\/2018-dodge-challenger-pcm-service-figure.webp\" alt=\"2018 Dodge Challenger PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">From the factory PCM removal procedure for the 2018 Dodge Challenger.<\/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 2018 Dodge Challenger<\/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 the negative battery cable.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the hood ajar switch.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the Powertrain Control Module (PCM) retaining bolt.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the PCM electrical connectors.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the PCM from the vehicle.<\/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 Reset<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">All configurations<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.3 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 module, the factory procedure calls for programming the unit with the original VIN and mileage, as noted in the installation guidelines.
