But did you know that the art of coding a car can be done in the comfort of your garage?&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Car Programming?<\/h2>\n\n\n\n<p>Vehicle programming is a complex process of understanding the aspects of the <a href=\"https:\/\/www.carparts.com\/engine-control-module\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"powertrain control module\">powertrain control module<\/a> (PCM) by inserting a read-only memory (ROM) file.

It simply <strong>lets you change the preprogrammed options that already came with the PCM<\/strong>.&nbsp;<\/p>\n\n\n\n<p>Coding a car can modify several vehicle functions, from deactivating the start\/stop feature and toggling the unlock and lock sound to disengaging the mirrors&rsquo; automatic folding capabilities. These are only some of the basic coding functions you can do with the on-board (OBD) computer.&nbsp;<\/p>\n\n\n\n<p>Other popular coding functions include modifying the lighting systems (flashing brake lights, adjusting the brightness of daytime running lights, etc.), tinkering with analog dashboard functions, and altering warning signals.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Will Coding Affect A Vehicle&rsquo;s Driving Performance?&nbsp;<\/h2>\n\n\n\n<p>Configuring some aspects of the PCM <strong>will not affect the engine<\/strong> per se. You&rsquo;ll still be able to drive your vehicle the same way you did before, although you might notice a few changes.&nbsp;<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<p>For example, if you deactivated your rearview camera, you could have trouble backing up or seeing the cars behind you. These changes are coming from you as the driver and not the vehicle.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can You Code Your Car?<\/h2>\n\n\n\n<p><strong>Yes, you can modify some settings on your vehicle&rsquo;s PCM<\/strong> with the right tools and know-how. In most cases, you&rsquo;ll need an OBD-to-ethernet\/USB adaptor, a laptop or computer, and the appropriate software.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Are the Limitations and Risks of Automotive Programming?<\/h2>\n\n\n\n<p>The modifications you can perform on your vehicle are <strong>limited to its make and model<\/strong>.
