Failure typically results in loss of engine control, communication errors, and may trigger diagnostic codes such as P0606 or P0607.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>PCM sits on the passenger\u2011side dash panel inside the engine bay.<\/li>\n<li>Replacement labor ranges from 0.3 to 0.8 hours depending on the unit.<\/li>\n<li>ABS controller should be disconnected temporarily to avoid VIN\u2011broadcast DTCs.<\/li>\n<li>Flagship One units arrive pre\u2011programmed with the correct VIN and mileage.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When a 2009 Dodge Ram experiences powertrain control problems, the PCM often becomes the focus of diagnosis. This guide explains where the module lives, what the factory recommends during removal and installation, and how Flagship One\u2019s pre\u2011programmed replacements simplify the post\u2011install steps. You will gain a clear picture of the work involved and the precautions needed to keep the ABS network and VIN broadcast functioning correctly.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2009 Dodge Ram Truck (Cummins)<\/h2>\n<p>In the 2009 Dodge Ram, the Powertrain Control Module governs fuel delivery, ignition timing, and transmission shift logic while also broadcasting the vehicle identification number over the communication bus. Its role is essential for engine performance and for systems that depend on VIN data, such as certain ABS controllers. Understanding this function helps you see why a proper replacement and programming are critical. <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/dodge-pcm-ecm-ecu-engine-computer\/ram-truck-cummins-engine-computers.html\">2009 Dodge Ram replacement PCM<\/a> ensures the vehicle runs as designed.<\/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 mounted in the engine compartment, attached to the passenger\u2011side dash panel. Access typically involves removing the dash cover and disconnecting the wiring harness. Labor times listed for removal and reinstall range from 0.3 hours for a simple reset to 0.8 hours for a full remove\u2011and\u2011replace on the diesel version. No additional torque specifications are provided, so follow standard connector seating practices.<\/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\/2009-dodge-ram-truck-cummins-pcm-location-card-1.webp\" alt=\"2009 Dodge Ram Truck (Cummins) PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">Typical PCM mounting area on the 2009 Dodge Ram Truck (Cummins) (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 2009 Dodge Ram Truck (Cummins)<\/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 isolator the negative battery cable.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Unplug<\/b> the four 38\u2013way connectors from the PCM.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the four PCM mounting bolts and remove the PCM from 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\">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\">5.7L<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.8 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\">DIESEL<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.8 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\">6.7L<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">1.8 hr<\/td>\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\">5.7L<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.8 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\">5.9L<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.8 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 using a scan tool to write the original VIN and mileage into the module, preventing DTCs related to VIN broadcast.
