Failure may cause drivability issues, no-start conditions, or stored trouble codes.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>PCM\/ECM replacement typically requires 0.5 hours of labor for removal and reinstallation.<\/li>\n<li>A relearn procedure, also 0.5 hours, is necessary after module replacement.<\/li>\n<li>Disconnecting the battery may require waiting time per factory caution.<\/li>\n<li>P0606 is a documented internal module trouble code for this vehicle.<\/li>\n<li>Access involves removing the negative battery cable only.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>If your 2013 Lexus LS460 is experiencing intermittent stalling, rough idle, or a no-start condition, the powertrain control module (PCM) or engine control module (ECM) may be at fault. These critical components manage engine performance, fuel delivery, and emissions systems. Replacing or reprogramming the module can restore proper operation, but the process requires careful adherence to factory procedures. Understanding the steps involved\u2014from access to relearn\u2014helps you make informed decisions about repairs and avoid unnecessary delays or complications.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2013 Lexus LS460<\/h2>\n<p>In the 2013 Lexus LS460, the PCM or ECM acts as the brain of the engine, continuously adjusting fuel injection, ignition timing, and emissions controls to optimize performance and efficiency. This module processes data from sensors throughout the vehicle to ensure smooth operation under varying conditions. A malfunctioning module may disrupt these adjustments, leading to poor drivability or even a complete failure to start. When replacement becomes necessary, <a href=\"https:\/\/www.fs1inc.com\/toyota-ecm-pcm-ecu-engine-computer\/lexus-ecm-pcm-ecu-engine-computer\/ls460-engine-computers.html\">replacement engine computers for the LS460<\/a> are designed to integrate seamlessly with the vehicle\u2019s systems, provided they are programmed and installed 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\/ECM in the 2013 Lexus LS460 is accessed by first disconnecting the negative battery cable. The factory cautions that a waiting period may be required after turning the ignition off before removing the cable to avoid electrical issues. Replacement involves removing the old module and installing the new one, a process that typically takes 0.5 hours of labor. The same amount of time is allocated for the relearn procedure, which ensures the module communicates properly with the vehicle\u2019s systems after installation.<\/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\/2013-lexus-ls460-pcm-service-figure.webp\" alt=\"2013 Lexus LS460 PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">From the factory PCM removal procedure for the 2013 Lexus LS460.<\/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 2013 Lexus LS460<\/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> COWL TOP VENTILATOR LOUVER RH More Info.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> cable from negative battery terminal.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> engine room ecu cover.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the 3 bolts and engine room ECU cover.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the 4 TCM connectors.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the 2 nuts and TCM.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the 2 engine wire connectors.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the 2 claws with the connector holder.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the 6 ECM connectors.<\/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 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<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Programming Requirements After Replacement<\/h2>\n<p>After installing a new PCM or ECM in your 2013 Lexus LS460, the factory procedure requires a relearn process to synchronize the module with the vehicle\u2019s systems.
