Failure typically disables sensor communication, triggers multiple diagnostic codes, and can prevent the vehicle from starting or shifting properly.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>PCM removal and installation generally require less than one hour of labor.<\/li>\n<li>Access involves removing several interior components to reach the module.<\/li>\n<li>Factory relearn procedures are needed after any PCM swap.<\/li>\n<li>Flagship One units arrive pre\u2011programmed to match the vehicle VIN.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When a 2016 Scion FR\u2011S exhibits intermittent powertrain faults, the PCM often becomes the focus of diagnosis. This guide explains what the module does, how to reach it, the steps required after replacement, and what you can expect from a properly programmed replacement. By the end, you\u2019ll understand the labor involved, the necessary post\u2011install procedures, and how to keep the new unit reliable.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2016 Scion FR-S<\/h2>\n<p>The Powertrain Control Module in a 2016 Scion FR\u2011S serves as the central computer that interprets sensor data and commands the engine and transmission. It ensures smooth acceleration, proper gear changes, and emission compliance. Because the PCM controls critical functions, any malfunction can lead to loss of power or drivability issues. Understanding its role helps you see why a proper replacement and calibration are essential. <a href=\"https:\/\/www.fs1inc.com\/toyota-ecm-pcm-ecu-engine-computer\/scion-ecm-pcm-ecu-engine-computer\/fr-s-engine-computers.html\">replacement powertrain control modules for the 2016 Scion FR\u2011S<\/a> keep the vehicle operating within design parameters.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The PCM resides behind the instrument panel on the right side, accessed by first disconnecting the negative battery lead, then removing the right\u2011hand instrument side panel, followed by the glove compartment door assembly and the control unit relay assembly. Labor times list 0.7 hours for removal and reinstall, plus an additional 0.5 hours for the relearn steps. The process typically involves careful handling of the connector harnesses and re\u2011torquing any mounting bolts to factory specifications if noted.<\/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\/2016-scion-fr-s-pcm-service-figure.webp\" alt=\"2016 Scion FR-S PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">From the factory PCM removal procedure for the 2016 Scion FR-S.<\/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 2016 Scion FR-S<\/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> instrument side panel rh.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> glove compartment door assembly.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> control unit relay assembly.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the 4 connectors from the ECM.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the 2 nuts and ECM.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> ECM 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\">0.7 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 the PCM is swapped, the factory requires a Powertrain Control Module relearn of 0.5 hours and an Engine Control Module relearn of 0.5 hours to synchronize sensor baselines.
