A failure typically results in loss of communication, stalling, or diagnostic codes such as P0606, indicating internal module malfunction.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>Module failure often triggers P0606 and loss of engine control.<\/li>\n<li>Factory removal requires disconnecting the negative battery cable and removing the air\u2011cleaner assembly.<\/li>\n<li>Flagship One supplies VIN\u2011programmed units, eliminating post\u2011install relearn steps.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When a 2013 Scion tC exhibits symptoms like stalling or a P0606 code, the powertrain or engine control module may need replacement. This guide walks you through locating the module, the labor involved, and what programming is required after installation. By the end, you will understand the steps to restore proper engine management and avoid common pitfalls during the repair.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2013 Scion tC<\/h2>\n<p>The powertrain control module in a 2013 Scion tC oversees both engine and transmission functions, translating sensor data into precise actuator commands. It works closely with the engine control module, which fine\u2011tunes fuel injection and ignition timing. Together they ensure smooth acceleration and fuel efficiency. Understanding their role helps you appreciate why a malfunction can cause no\u2011start conditions or erratic shifting. <a href=\"https:\/\/www.fs1inc.com\/toyota-ecm-pcm-ecu-engine-computer\/scion-ecm-pcm-ecu-engine-computer\/tc-engine-computers.html\">replacement engine control modules for 2013 Scion tC<\/a> are designed to meet the same performance standards as the original units.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The control module sits beside the air cleaner assembly, accessed by removing the cable from the negative battery terminal, the air cleaner cap sub\u2011assembly, the air cleaner case, and the air cleaner inlet. The factory removal procedure reaches the module after these components are taken off. Labor times are listed as 0.7 hours for removal and replacement of the powertrain control module and 0.7 hours for the engine control module, with an additional 0.5 hour relearn for each module 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-scion-tc-ecm-location-card.webp\" alt=\"2013 Scion tC PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">Typical PCM mounting area on the 2013 Scion tC (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 2013 Scion tC<\/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.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> air cleaner cap sub-assembly.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the mass air flow meter connector.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the purge VSV connector.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Detach<\/b> the 2 wire harness clamps.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the 2 purge line hoses.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the No.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the purge line hose from the clamp.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Detach<\/b> the 2 hook clamps, and then remove the air cleaner cap.<\/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\">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 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\">0.7 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 module in a 2013 Scion tC, the factory procedure calls for a powertrain control module relearn of 0.5 hours and an engine control module relearn of 0.5 hours.
