The PCM is the central computer that coordinates engine and transmission operation. This article explains what the PCM does, where it is located, common failure symptoms, and what to expect during replacement. You will also learn about a factory service bulletin that addresses a specific trouble code, and how choosing a pre-programmed module can simplify the repair. The goal is to give you the knowledge to diagnose and address PCM issues confidently.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2012 Dodge Charger<\/h2>\n<p>The Powertrain Control Module (PCM) in the 2012 Dodge Charger 3.6L is a single unit that combines the functions of an Engine Control Module (ECM) and a Transmission Control Module (TCM). It receives data from sensors such as the manifold absolute pressure (MAP) sensor, crankshaft position sensor, and oxygen sensors, then adjusts fuel delivery, ignition timing, and transmission shift points accordingly. The PCM also communicates with other modules on the vehicle&#8217;s CAN bus network. When you need a replacement, you are looking for <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/dodge-pcm-ecm-ecu-engine-computer\/charger-engine-computers.html\">replacement PCMs for the 2012 Charger<\/a> that are pre-programmed with your VIN and mileage to avoid additional steps. A failing PCM can cause a range of drivability problems, from rough running to a complete no-start.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The PCM on the 2012 Dodge Charger is located in the engine compartment, typically mounted near the air filter housing or on the driver-side strut tower. According to factory labor times, removing and replacing the PCM (R&amp;R) is a 0.6-hour job. After installation, a PCM relearn procedure is required, which adds 0.5 hours of labor. The relearn process involves using a scan tool to reset adaptive values and confirm communication with all sensors. Access is straightforward, but care must be taken to disconnect the battery and avoid damaging the connector pins. No special tools are needed beyond basic hand tools and a scan tool for the relearn.<\/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\/2012-dodge-charger-pcm-location-card-1.webp\" alt=\"2012 Dodge Charger PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">Typical PCM mounting area on the 2012 Dodge Charger (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 2012 Dodge Charger<\/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 two push pins that secure the front cowl top panel to the right rear corner o.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the front cowl top panel.<\/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>When a new PCM is installed in the 2012 Dodge Charger, the factory procedure requires programming it with the original Vehicle Identification Number (VIN) and mileage. This step is essential for the module to communicate with the vehicle&#8217;s security system and other modules. A dealer or qualified shop uses a scan tool to perform this programming, which is included in the 0.5-hour relearn labor time. However, if you purchase <a href=\"https:\/\/www.fs1inc.com\/2012-dodge-charger-3-6l-engine-computer-pcm-ecm-ecu-programmed-plug-play.html\">a VIN-programmed replacement unit<\/a> from Flagship One, that programming is already completed before shipping. The module arrives ready to install, and the only remaining step is the relearn procedure to synchronize adaptive values. This saves you the time and cost of the initial VIN programming step.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Symptoms of a Failing PCM<\/h2>\n<p>A failing PCM in the 2012 Dodge Charger 3.6L can produce several noticeable symptoms. The engine may crank but not start, or it may start and stall shortly after. You might experience erratic shifting, hesitation during acceleration, or a sudden loss of power. The check engine light often illuminates, and the vehicle may enter a limp-home mode with reduced performance. Scan tool communication can be lost entirely, or the tool may report a <a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0601-internal-control-module-memory-checksum-error\/\">internal PCM fault P0601<\/a> that indicates a memory or processor issue. Other common codes include misfire or sensor circuit faults. If multiple unrelated codes appear simultaneously, the PCM is a likely suspect.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Module Trouble Codes on the 2012 Dodge Charger<\/h2>\n<p>The PCM in the 2012 Dodge Charger can store internal trouble codes that point to module failure.
