This guide walks you through the steps to reset, relearn, or replace the PCM, and explains why each step matters. You\u2019ll learn the exact location of the module, the labor times involved, and how to avoid common mistakes that could leave your vehicle inoperable. By following these instructions, you\u2019ll gain confidence that the PCM is functioning correctly and that your Lexus will return to its smooth, reliable driving experience.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2020 Lexus UX250h<\/h2>\n<p>The PCM in the 2020 Lexus UX250h is the central brain that coordinates engine timing, fuel injection, and transmission shift points. It receives inputs from sensors such as the crankshaft position sensor, throttle position sensor, and camshaft position sensor, then outputs commands to the engine control unit and transmission control module. <a href=\"https:\/\/www.fs1inc.com\/lexus-ecm-pcm-ecu-engine-computer.html\">Powertrain Control Module for 2020 Lexus UX250h<\/a> This module ensures that the vehicle runs efficiently and that safety systems like traction control remain responsive. A malfunctioning PCM can trigger fault codes, reduce engine performance, or even prevent the vehicle from starting. Understanding its role helps technicians isolate issues and decide whether a reset, relearn, or replacement is necessary.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The PCM sits directly beside the air cleaner assembly in the engine bay. To access it, the technician must first remove the cable from the negative auxiliary battery terminal, then work through a series of components: the No. 1 Engine Cover Sub\u2011Assembly, the Radiator Support Opening Cover, the No. 1 Air Cleaner Inlet, the Air Cleaner Cap with Air Cleaner Hose, and the Air Cleaner Filter Element Sub\u2011Assembly. The factory removal procedure typically takes about 0.8 hours for a complete removal or 0.5 hours for a relearn. During the process, the technician should follow the book times and carefully route the negative battery cable to avoid damage to the harness.<\/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\/2020-lexus-ux250h-ecm-location-card.webp\" alt=\"2020 Lexus UX250h PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">Typical PCM mounting area on the 2020 Lexus UX250h (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 2020 Lexus UX250h<\/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> cable from negative auxiliary battery terminal.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>REMOVE<\/b> RADIATOR SUPPORT OPENING COVER Click here More Info.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>REMOVE<\/b> AIR CLEANER CAP WITH AIR CLEANER HOSE Click here More Info.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>REMOVE<\/b> AIR CLEANER FILTER ELEMENT SUB-ASSEMBLY Click here More Info.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> air cleaner case sub-assembly.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the 2 bolts.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the 3 connectors from the engine room relay block.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Raise<\/b> the 2 lock levers while pushing the locks on the levers, and disconnect the 2 ECM connect.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the bolt to separate the engine wire.<\/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\">0.8 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\">0.8 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 installing a new PCM, the factory requires a series of calibration and initialization steps to ensure proper communication with the vehicle\u2019s systems.
