A failure typically triggers the P0606 code and can cause loss of power, stalling or no\u2011start conditions.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>PCM and ECM removal each require about 0.7\u202fhours of labor.<\/li>\n<li>Relearn procedures add roughly 0.5\u202fhours for each module.<\/li>\n<li>The control modules sit beside the air\u2011cleaner assembly and need several components removed to access.<\/li>\n<li>After replacement, a VIN\u2011programmed unit eliminates the need for additional programming steps.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When a 2012 Scion tC begins to exhibit intermittent power loss, rough idle or a persistent P0606 code, the powertrain and engine control modules are likely suspects. This guide explains where the modules reside, what labor is involved in taking them out and installing new units, and which post\u2011install procedures are required. By following the outlined steps you can understand the scope of the job and what to expect from a professional repair or a quality refurbished replacement.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2012 Scion tC<\/h2>\n<p>The Powertrain Control Module (PCM) and Engine Control Module (ECM) in the 2012 Scion tC act as the vehicle\u2019s brain, continuously monitoring sensor data to regulate fuel injection, ignition timing and transmission shift points.
