Furthermore, the body control module also talks with the car&rsquo;s other computers through the CAN bus system.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tips on How to Access the Body Control Module<\/h2>\n\n\n\n<p>It&rsquo;s extremely important to note that there are multiple modules and you can easily misidentify another module believing it to be the BCM. Furthermore, even if you get the right BCM for your vehicle, it will typically need to be programmed by a dealer or well-equipped shop. Most modules are that way on newer cars, so be aware of that before you attempt to replace your BCM or any other module. They aren&rsquo;t &ldquo;plug and play&rdquo; the way they used to be.<\/p>\n\n\n\n<p>You can start by consulting your owner&rsquo;s manual, but you won&rsquo;t usually find the location of the body control module there. Typically, you&rsquo;ll need to check a shop manual or an online source like a forum for the precise location of your specific vehicle&rsquo;s BCM.<\/p>\n\n\n\n<p>Always disconnect your car&rsquo;s battery before accessing the body control module. The battery supplies the BCM with a trickle of power. Disconnecting it will reduce the chance of electric shocks while you handle the part. Cutting off the power will also prevent potential electrical damage to the computer.<\/p>\n<\/body><\/html>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Reading Time: <\/span> <span class=\"rt-time\"> 2<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>In many vehicles, the body control module (BCM) is underneath the dashboard on the center console&rsquo;s driver side.
