When internal diagnostics detect memory faults, the PCM may trigger P0601 or P0606, leading to drivability complaints or failure to communicate with a scan tool.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>P0601 typically indicates an internal checksum error within the PCM&#8217;s memory, suggesting electronic degradation inside the module itself.<\/li>\n<li>P0606 commonly reports that the PCM processor has failed its internal self-test, which can cause a no-start or limp-home condition.<\/li>\n<li>Factory labor to remove and reinstall the module on this vehicle is listed at 0.5 hours, with an additional 0.5 hours for the relearn procedure.<\/li>\n<li>The module sits adjacent to the air cleaner assembly, which the factory service procedure identifies as the access point for removal.<\/li>\n<li>After replacement, the new module must be reprogrammed with the vehicle&#8217;s original identification number and recorded mileage.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When a 2013 Jeep Compass sets trouble codes P0601 or P0606, the vehicle&#8217;s owner faces a decision about the powertrain control module. These codes indicate that the module has detected an internal fault rather than a problem with external sensors. This article explains how the module functions, where it is located on this specific vehicle, what the replacement procedure entails according to factory information, and what steps must be taken after installation to restore proper operation. Understanding these details helps you evaluate repair options and communicate effectively with a service provider.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2013 Jeep Compass<\/h2>\n<p>The powertrain control module on the 2013 Jeep Compass serves as the primary computer responsible for regulating engine operation. It processes input from numerous sensors to control fuel injection, ignition timing, variable valve timing, and the automatic transmission&#8217;s shift schedule on equipped models. The module also manages emissions-related functions, including the Evaporative system and upstream oxygen sensor feedback loops. Because this computer interfaces with virtually every major system under the hood, a failure can produce wide-ranging symptoms from poor idle quality to a complete no-start condition. <a href=\"https:\/\/www.fs1inc.com\/jeep-ecu-ecm-pcm\/compass-engine-computers-ecm-pcm-ecu.html\">replacement engine computers for the Jeep Compass<\/a> often become necessary when the internal processor or memory sectors develop faults that resist software-level repair.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>According to the factory removal procedure, the control module on the 2013 Jeep Compass is positioned next to the air cleaner assembly. This placement determines the access path for replacement. The book time for removing and reinstalling the module on this vehicle is 0.5 hours. After the hardware is installed, an additional 0.5 hours is allocated for the relearn procedure to allow the new module to calibrate to the specific vehicle. The actual shop time may vary depending on connector condition and whether any mounting hardware has seized. Technicians typically disconnect the battery before beginning work to eliminate the risk of short circuits at the module harness.<\/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\/2013-jeep-compass-pcm-location-diagram.webp\" alt=\"2013 Jeep Compass PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">PCM mounting location on the 2013 Jeep Compass.<\/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 2013 Jeep Compass<\/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> negative battery cable.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the Powertrain Control Module (PCM) harness connectors.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> bolts and the PCM from the air cleaner housing.<\/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 R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Compass<\/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\">Patriot<\/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 Relearn<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Compass<\/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 Relearn<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Patriot<\/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\">Compass<\/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\">Patriot<\/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>The factory installation procedure for the 2013 Jeep Compass requires using a scan tool to reprogram the replacement module with the vehicle&#8217;s original identification number and the original recorded mileage.
