A failure typically results in engine warning lights, poor performance, or loss of driveability, and may trigger the internal P0605 fault code.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>Factory removal accesses the ECM beside the air cleaner assembly.<\/li>\n<li>Labor time for removal and relearn is roughly 0.6 and 0.5 hours each.<\/li>\n<li>Installation bolts require torque between 7.8 and 11.8 N\u00b7m.<\/li>\n<li>VIN must be programmed into the new ECM after install.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When the engine warning lamp illuminates on your 2010 Hyundai Santa Fe, the ECM may be at fault. This guide explains what the module does, where it lives, how long a shop typically spends on removal and relearn, and what programming steps are needed. By the end you will understand the key steps to get your vehicle back to normal operation with confidence.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2010 Hyundai Santa Fe<\/h2>\n<p>The Engine Control Module in a 2010 Hyundai Santa Fe receives data from dozens of sensors and directs fuel injection, spark timing and emission controls. It also stores diagnostic trouble codes and communicates with the Powertrain Control Module. Proper operation is essential for smooth acceleration, fuel efficiency and emissions compliance. <a href=\"https:\/\/www.fs1inc.com\/hyundai-ecm-pcm-ecu-engine-computer\/santa-fe-engine-computers.html\">replacement engine computers for the 2010 Hyundai Santa Fe<\/a> ensure that the vehicle runs as designed and that fault codes are logged correctly.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The ECM is located next to the air cleaner assembly, allowing access without removing major drivetrain components. The factory removal procedure reaches the control module in that position. Labor guidelines list 0.6 hours for removal and another 0.6 hours for reinstallation. After the unit is secured, the bolts should be tightened to a range of 7.8 to 11.8 N\u00b7m. The relearn process adds an additional 0.5 hours each for the ECM and PCM.<\/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\/2010-hyundai-santa-fe-ecm-location-card-1.webp\" alt=\"2010 Hyundai Santa Fe PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">Typical PCM mounting area on the 2010 Hyundai Santa Fe (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 2010 Hyundai Santa Fe<\/h3>\n<ol style=\"margin:14px 0 6px 0;padding-left:26px\">\n<li style=\"margin:10px 0;line-height:1.65\"><b>Turn<\/b> ignition switch OFF and disconnect the negative (-) battery cable.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the ECM connector.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the air cleaner assembly.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>After<\/b> removing the installation bolts, remove the ECM from the 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 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\">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\">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<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<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Programming Requirements After Replacement<\/h2>\n<p>After the ECM is installed, the factory service requires the vehicle identification number to be programmed into the module.
