Failures may cause erratic engine behavior, poor performance, or complete stalls, often triggered by voltage spikes or corrosion.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>The PCM controls engine and transmission functions in the 1996 Concorde.<\/li>\n<li>Replacement typically requires 0.5 hours for removal and reinstallation.<\/li>\n<li>A relearn procedure (0.5 hours) is needed after installation unless using a VIN-programmed unit.<\/li>\n<li>Common symptoms include no-start conditions, stalling, or false check-engine lights.<\/li>\n<li>Factory recalls and bulletins address reprogramming and false fault codes.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>If your 1996 Chrysler Concorde hesitates at idle, refuses to start, or suddenly triggers the check-engine light, the Powertrain Control Module (PCM) may be the culprit. This small but critical computer oversees everything from fuel injection to transmission shifting, acting as the brain of your vehicle\u2019s drivetrain. When it fails, symptoms can range from subtle performance glitches to complete immobilization. Replacing the PCM isn\u2019t just about swapping hardware\u2014it involves precise programming to match your Concorde\u2019s specific configuration. Understanding the process, from locating the module to ensuring proper calibration, can save you time and frustration. Whether you\u2019re diagnosing a persistent issue or preparing for a replacement, knowing what to expect helps you make informed decisions about repairs or upgrades.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 1996 Chrysler Concorde<\/h2>\n<p>The Powertrain Control Module in the 1996 Chrysler Concorde serves as the central command for engine and transmission operations. It continuously monitors sensors for air intake, throttle position, and exhaust composition, adjusting fuel delivery and ignition timing in real time. This ensures optimal performance while meeting emissions standards. The module also manages transmission shift points, adapting to driving conditions for smooth acceleration. When the PCM malfunctions, your Concorde may experience rough idling, misfires, or even fail to start, as the engine loses its ability to regulate critical functions. Because the system relies on precise data, even minor voltage irregularities or corrosion in connectors can disrupt its operation. For owners facing persistent drivability issues, replacing the module with <a href=\"https:\/\/www.fs1inc.com\/chrysler-dodge-plymouth\/chrysler-pcm-ecm-ecu-engine-computer\/concorde-engine-computers.html\">replacement engine computers for the Concorde<\/a> may restore lost functionality, but proper programming is essential to avoid further complications.<\/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 the 1996 Chrysler Concorde is positioned next to the air cleaner assembly, making it relatively accessible compared to modules tucked behind dash panels or under seats. To replace it, you\u2019ll need to disconnect the battery, remove the air cleaner housing, and unplug the wiring harness from the module. The factory procedure specifies no additional disassembly, though you may need to maneuver around nearby components. Labor time for removal and reinstallation is typically 0.5 hours, assuming no complications like seized connectors or damaged mounting points. Once the new unit is installed, securing it properly ensures a stable connection, as vibrations or loose fittings can lead to intermittent faults. Always verify that the harness is fully seated and free of debris before reassembling the air cleaner.<\/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\/1996-chrysler-concorde-ecm-location-card-1.webp\" alt=\"1996 Chrysler Concorde PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">Typical PCM mounting area on the 1996 Chrysler Concorde (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 1996 Chrysler Concorde<\/h3>\n<ol style=\"margin:14px 0 6px 0;padding-left:26px\">\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> air cleaner.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> PCM 2 40-way connector ivattachingbolts.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> 2 bolts from PCM bracket.<\/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\">0.5 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\">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\">0.5 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 PCM in your 1996 Chrysler Concorde, the factory procedure requires a relearn process to synchronize the module with the vehicle\u2019s sensors and transmission. This step, which typically takes 0.5 hours, ensures the engine and drivetrain operate smoothly without hesitation or error codes. However, if you opt for <a href=\"https:\/\/www.fs1inc.com\/1996-chrysler-concorde-3-5l-engine-computer-pcm-ecm-ecu-programmed-plug-play.html\">a VIN-programmed replacement unit<\/a>, these calibration steps are already completed, eliminating the need for additional shop time. The module arrives ready to communicate with your Concorde\u2019s systems, reducing the risk of post-installation glitches. Without pre-programming, you may need specialized tools like the DRBIII scan tool to perform the relearn, adding complexity to the repair. For owners seeking a straightforward solution, a pre-configured unit simplifies the process while maintaining factory-level performance.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Symptoms of a Failing PCM<\/h2>\n<p>A failing PCM in the 1996 Chrysler Concorde often announces itself through a range of frustrating symptoms. One of the most common is a no-start condition, where the engine cranks but refuses to fire, as the module fails to deliver spark or fuel. Stalling at idle or during acceleration may also occur, particularly if the PCM loses its ability to adjust air-fuel ratios in real time. Some owners report erratic shifting, with the transmission hesitating or jerking between gears, as the module struggles to manage hydraulic pressures. Check-engine lights are another frequent sign, sometimes triggered by false codes like an internal control module memory error, even when no mechanical issue exists. In severe cases, the vehicle may enter a \u201climp mode,\u201d severely limiting power to prevent further damage.
