When it fails, the engine may not start, run poorly, or trigger warning lights. Replacement requires proper programming.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>The PCM is located in the engine compartment of the 1995 Dodge Ram Van.<\/li>\n<li>Factory book time for ECM removal and replacement on the Van is 0.4 hours.<\/li>\n<li>After replacing the PCM, a relearn procedure is required, taking 0.5 hours per the factory manual.<\/li>\n<li>Flagship One provides VIN-programmed units that eliminate the need for a dealer relearn.<\/li>\n<li>A factory service bulletin (18-037-05) covers flash programming failure recovery using the DRBIII scan tool.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>If your 1995 Dodge Ram Van 3.9L is experiencing no-start conditions, stalling, or erratic transmission behavior, the powertrain control module (PCM) may be at fault. This computer controls critical engine and transmission functions, and when it fails, the vehicle often becomes undrivable. This guide explains what the PCM does in your Ram Van, where it is located, how replacement is performed, and what programming steps are needed afterward. You will also learn about common failure symptoms and a relevant factory service bulletin. Understanding these details helps you make an informed decision about repairing or replacing the module.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 1995 Dodge Ram Van<\/h2>\n<p>The powertrain control module (PCM) in your 1995 Dodge Ram Van 3.9L is the central computer that manages engine operation, including fuel injection, ignition timing, and idle speed, as well as transmission shift scheduling. It receives input from sensors such as the crankshaft position sensor, throttle position sensor, and oxygen sensor, then adjusts outputs to maintain performance and emissions compliance. Because this vehicle is pre-OBD-II, the PCM does not use generic P-codes but stores its own diagnostic trouble codes that can be retrieved with a scan tool or by observing the check engine light flash pattern. When the PCM fails, the engine may not start, may stall unpredictably, or may run in a reduced-power limp mode. Replacing a faulty PCM with a quality unit like <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/dodge-pcm-ecm-ecu-engine-computer\/ram-van-engine-computers.html\">replacement ECMs for the Ram Van<\/a> restores proper operation, but the new module must be programmed with the vehicle&#8217;s VIN and calibration data to function correctly.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The PCM in your 1995 Dodge Ram Van 3.9L is located in the engine compartment, typically mounted on the driver-side inner fender or near the firewall. Access requires removing any covers or air intake ducts that may obstruct the module. According to factory labor guides, removing and replacing the engine control module (ECM) on the Van takes 0.4 hours. The module is secured by bolts or screws, and the 60-way connector must be carefully unlatched. After installation, a relearn procedure is necessary to synchronize the PCM with the vehicle&#8217;s systems. The factory book time for the PCM relearn on the Van is 0.5 hours. Ensure the battery is fully charged and all connections are clean before beginning the replacement.<\/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\/1995-dodge-ram-van-pcm-location-card-1.webp\" alt=\"1995 Dodge Ram Van PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">Typical PCM mounting area on the 1995 Dodge Ram Van (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 1995 Dodge Ram Van<\/h3>\n<ol style=\"margin:14px 0 6px 0;padding-left:26px\">\n<li style=\"margin:10px 0;line-height:1.65\"><b>Connect<\/b> vacuum harness and wiring connector.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> wiring connector at solenoid.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> solenoid and its support bracket from intake manifold.<\/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\">Van<\/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\">Truck<\/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\">Van<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.4 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\">Truck<\/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\">GAS<\/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\">DIESEL<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.7 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\">GAS<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.4 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\">Van<\/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 new or replacement PCM in your 1995 Dodge Ram Van 3.9L, the factory procedure requires a relearn process that takes 0.5 hours. This involves using a scan tool to program the module with the vehicle&#8217;s VIN and calibration data, then performing a drive cycle to adapt the idle and transmission shift points. Flagship One eliminates this step by providing <a href=\"https:\/\/www.fs1inc.com\/1995-dodge-ram-van-1500-2500-3500-3-9l-pcm-engine-computer-ecm-ecu-programmed-plug-play.html\">a VIN-programmed replacement unit<\/a> that arrives ready to install.
