class=\"kt-inside-inner-col\">\n<div class=\"protip-desc\">\n\t<div class=\"help-tip\">\n\t\t<p><strong>Pro Tips<\/strong> are nuggets of information direct from ASE-certified automobile technicians working with CarParts.com, which may include unique, personal insights based on their years of experience working in the automotive industry. These can help you make more informed decisions about your car.<\/p>\n\t<\/div>\n    <div class=\"help-caption\">\n        <p>\n            <strong>Pro Tip:<\/strong>\n            Late 80s Eagle Premiers had a lighting control module that controlled every external light. The oddity of this French-designed system was that the lights were hard-wired to power and the LCM provided ground signals to the lights.\n        <\/p>\n    <\/div>\n<\/div>\n<\/div><\/div>\n\n<\/div><\/div><\/div><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Improved Energy Efficiency<\/h3>\n\n\n\n<p>In the same vein as automatic adjustments, the LCM can dim or turn off the lights if necessary to reduce unnecessary energy consumption.<\/p>\n\n\n\n<p>You might also see a decrease in fuel consumption because turning on the lights results in more load on the dynamo, the component that converts energy from engine fuel into electrical energy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Fault Detection<\/h3>\n\n\n\n<p>LCMs on modern cars can also detect faults in the lighting system. For example, the LCM could alert you if a bulb is burnt out by showing &ldquo;left\/right side light out&rdquo; bulb lights on your dashboard.<\/p>\n\n\n\n<p>Knowing whether your car bulbs are working properly is crucial, especially on difficult terrains and low-visibility scenarios. If the LCM detects that one is faulty, you can change it before going on a trip, ensuring you get optimal visibility when you drive after dark.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Signs of a Failing Light Control Module<\/h2>\n\n\n\n<p>Some signs of a failing LCM include the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The headlight, taillights, and brake lights aren&rsquo;t working.<\/li>\n\n\n\n<li>The turn signals and emergency hazard lights don&rsquo;t blink or are blinking too quickly.<\/li>\n\n\n\n<li>The dashboard is not illuminating.<\/li>\n<\/ul>\n\n\n\n<p>These are all light-related issues. As such, they don&rsquo;t always correlate to a malfunctioning light control module. For one, the bulbs of the listed lights might have simply gone out or the dashboard itself is damaged.<\/p>\n\n\n\n<p>However, it&rsquo;s still worth listing the LCM as the potential cause of problems. In some cases, resetting or replacing the LCM can resolve.<\/p>\n\n\n\n\n\n\n<h2 class=\"wp-block-heading\">How to Reset the Light Control Module<\/h2>\n\n\n\n<p>There are two ways you can reset the LCM: by manually resetting it or using an <a href=\"https:\/\/www.carparts.com\/scan-tool\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"OBD scanner\">OBD scanner<\/a>. Before doing so, check your owner&rsquo;s manual for specific instructions, as resetting the LCM may vary depending on the car model.<\/p>\n\n\n\n<p>You must also ensure the battery is fully charged for a smoother reset process. Lastly, disconnect any aftermarket lighting accessories to avoid interference during the process.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Manually Resetting the Light Control Module<\/h3>\n\n\n\n<p>To manually reset the LCM, follow the steps below:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Step 1: <\/strong>Open the hood of your car and disconnect the negative battery cable to cut off the LCM&rsquo;s power supply. Use a wench\/plier to loosen the nut\/bolt that secures the negative cable (black cable). Remove the cable and set it aside.<\/li>\n\n\n\n<li><strong>Step 2: <\/strong>Wait at least 15 minutes for the LCM to reset and clear temporary settings or fault codes.<\/li>\n\n\n\n<li><strong>Step 3:<\/strong> Afterward, reconnect the negative battery cable by placing it back in the terminal. Use the wrench\/pliers to secure the cable by tightening the nut\/bolt.<\/li>\n\n\n\n<li><strong>Step 4: <\/strong>Test all the lights, especially the malfunctioning ones.<\/li>\n<\/ul>\n\n\n\n<p>If the lights are still not working, consult a professional, as they&rsquo;ll have more knowledge and experience dealing with LCM issues.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Using an OBD Scanner to Reset the Light Control Module<\/h3>\n\n\n\n<p>If you have an OBD scanner on hand, you can use it to reset different modules, including the LCM. To do so, follow the steps below:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Step 1:<\/strong> Plug the scanner into the port, usually located under the dashboard on the driver&rsquo;s side. Turn on the ignition, but don&rsquo;t start the engine. Wait for the scanner to establish communication with the vehicle&rsquo;s systems.<\/li>\n\n\n\n<li><strong>Step 2:<\/strong> Navigate the scanner&rsquo;s menu and select the one related to the LCM. This differs depending on the scanner, but it should indicate &ldquo;lighting.&rdquo;<\/li>\n\n\n\n<li><strong>Step 3: <\/strong>Press the reset or initialize option on your scanner and follow the instructions on the screen. The resetting process could take a few minutes.<\/li>\n\n\n\n<li><strong>Step 4: <\/strong>After the process, look at the screen for any fault codes. If there are none, it means the reset was complete. However, if a code is present, it may be best to take your vehicle to an auto shop for professional assistance.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How to Replace the Light Control Module<\/h2>\n\n\n\n<p>If resetting the LCM doesn&rsquo;t solve the issues, it might be better to replace the old module. To do so, follow the steps below:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Step 1:<\/strong> Turn off the car and remove the keys from the ignition before disconnecting the negative terminal of the car battery.<\/li>\n\n\n\n<li><strong>Step 2:<\/strong> Locate the LCM, which is usually underneath the steering wheel. If not, you can always check your owner&rsquo;s manual for its location.<\/li>\n\n\n\n<li><strong>Step 3: <\/strong>Remove the old module by removing panels or covers, disconnecting the wiring harness connected to the module, and unbolting it by removing screws.<\/li>\n\n\n\n<li><strong>Step 4: <\/strong>Place the new module in the same position as the old one and reconnect the wires you removed. Afterward, bolt or screw it into place.<\/li>\n\n\n\n<li><strong>Step 5:<\/strong> Reconnect the battery and turn the car on to see if the lights function.<\/li>\n\n\n\n<li><strong>Step 6: <\/strong>If everything works fine, reassemble the panels or covers you removed.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Where to Get a Replacement Light Control Module<\/h2>\n\n\n\n<p>As mentioned, replacing the LCM is a viable option if resetting it doesn&rsquo;t fix the issue.
