Failure of either unit can trigger diagnostic codes, cause loss of power, and prevent the vehicle from starting or running smoothly.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>Replacement labor is typically 0.7\u202fhours for each module.<\/li>\n<li>Access requires removing the negative battery cable.<\/li>\n<li>After engine shutdown, wait at least 60\u202fseconds before battery disconnection.<\/li>\n<li>P0606 indicates internal PCM\/ECM communication trouble.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When a 2013 Lexus IS350C exhibits powertrain control errors, the repair path often starts with the PCM or ECM. Understanding how these computers function, the steps to reach them, and the post\u2011install requirements helps you avoid unnecessary downtime. This guide explains the module\u2019s role, the removal process, and what to expect after a replacement, so you can make an informed decision for your vehicle.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2013 Lexus IS350C<\/h2>\n<p>The Powertrain Control Module in a 2013 Lexus IS350C acts as the central brain for engine and transmission functions, interpreting sensor data to adjust fuel, spark, and shift timing. It works together with the Engine Control Module, which fine\u2011tunes combustion and emissions. A fault in either unit can lead to loss of driveability, and the vehicle may store the diagnostic code P0606. Proper operation is essential for performance and emissions compliance. <a href=\"https:\/\/www.fs1inc.com\/toyota-ecm-pcm-ecu-engine-computer\/lexus-ecm-pcm-ecu-engine-computer\/is350c-engine-computers.html\">2013 Lexus IS350C replacement<\/a> ensures the vehicle runs as engineered.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The PCM and ECM are located behind the engine compartment and are accessed by first disconnecting the cable from the negative battery terminal. The factory caution advises a 60\u2011second pause after the engine switch is turned off before this cable is removed. Once the cable is free, the modules can be removed and replaced, each task taking about 0.7\u202fhours of labor according to the service book.<\/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-is350c-pcm-service-figure.webp\" alt=\"2013 Lexus IS350C 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 IS350C.<\/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 IS350C<\/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 BATTERY TERMINAL REMOVE COOL AIR INTAKE DUCT SEAL More Info.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>REMOVE<\/b> ENGINE ROOM SIDE COVER LH More Info.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> ECM cover.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the 3 bolts and ECM cover.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> all water on and around the ECM cover.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the ECM connectors.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the 6 ECM connectors.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the 2 nuts and ECM.<\/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\">0.7 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\">All configurations<\/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 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 unit, the factory procedure includes an Engine Control Module relearn that typically requires 0.5\u202fhours.
