Cruise control not working after battery change<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Possible cause \u2014 <\/strong>This differs from vehicle to vehicle and among brands. Some drivers\u2019 cruise control malfunctions after jump-starting their battery, and this is because the battery is still discharged. Newer cars have many electronic systems, and most are powered by the battery. So, if the battery is discharged or low-powered, the electrical cruise control system can be affected.<\/li><li><strong>Solution \u2014 <\/strong>Putting your battery on a trickle charger (2-5 amp) for 12 hours or driving on cruise for a couple of hours may resolve this issue.<\/li><\/ul>\n\n\n\n<p><strong>2. Cruise control turns off while driving<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Possible cause \u2014 <\/strong>Damaged speed sensor or actuator, these two could be internally malfunctioning and causing the cruise control to disengage without input from you.<\/li><li><strong>Solution \u2014 <\/strong>Have a technician or mechanic run a diagnostic with the speed sensor and check the actuator hoses and cables.<\/li><\/ul>\n\n\n\n<p><strong>3. Cruise control works intermittently<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Possible cause<\/strong> \u2014 this may relate to the brake pedal switch. If cruise control is intermittently disengaging, it could be a wiring issue with the switch.<\/li><li><strong>Solution<\/strong> \u2014 Have the brake pedal to cruise control switch investigated by a mechanic or technician and determine if there is a faulty wire to blame. You may need to have the switch or some of its parts replaced.<\/li><\/ul>\n\n\n\n<p><strong>4. Cruise control turns on but will not set<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Possible cause \u2014 <\/strong>The brake pedal switch may be the issue. The brake pedal deactivates cruise control and if it is stuck in the open position, it may cause the cruise control to not engage or set properly.<\/li><li><strong>Solution \u2014 <\/strong>Ask your mechanic or technician to check for this issue specifically in their diagnostic and service.<\/li><\/ul>\n\n\n\n<p><strong>5. Cruise control turns on by itself<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Possible cause \u2014 <\/strong>There may be a failure with the Electronic Control Module (ECM) which manages the actuators or Electronic Control Unit (ECU) which controls the speed in your cruise control<\/li><li><strong>Solution \u2014 <\/strong>You could attempt to reprogram the ECU and ECM if you have the computer tools, otherwise take it into a trusted mechanic or technician.<\/li><\/ul>\n\n\n\n<p><strong>There are many helpful forums run by mechanics and amateurs:&nbsp; <\/strong>These are always great for solving those <em>specific<\/em> problems you might experience. <strong><\/strong><\/p>\n\n\n\n<p>When CC does not set: <a href=\"https:\/\/mechanics.stackexchange.com\/questions\/34795\/cruise-control-will-not-turn-on-cannot-be-enabled-nor-set\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/mechanics.stackexchange.com\/questions\/34795\/cruise-control-will-not-turn-on-cannot-be-enabled-nor-set<\/a><\/p>\n\n\n\n<p>When CC is faulty after battery change: <a href=\"https:\/\/www.vwvortex.com\/threads\/help-cruise-control-not-working-after-dead-battery.4464553\/\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/www.vwvortex.com\/threads\/help-cruise-control-not-working-after-dead-battery.4464553\/<\/a><\/p>\n\n\n\n<p>For cruise control and other general repairs, watch this channel: <a href=\"https:\/\/www.youtube.com\/channel\/UCf2f4MeZzSksVMe1z3Lp3hw\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/www.youtube.com\/channel\/UCf2f4MeZzSksVMe1z3Lp3hw<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"FAQ\"><\/span><strong>FAQ<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Can cruise control cause check engine light?<\/strong><\/h3>\n\n\n\n<p>When the check engine light or MIL (Malfunction Indicator Light) is on, the cruise control light may blink to signal that cruise control has been disabled. This is a safety control as the vehicle is programmed to not go on \u2018autopilot\u2019 should the engine or mechanical issue relate to the cruise control systems. If the error or fault is with the cruise control systems, then the MIL may be lit for that as well.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How much does it cost to fix cruise control malfunctions?<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>For switch repair (parts and labour) it\u2019s estimated at $125- $350<\/li><li>For fuse repairs, it could be up to $10 to buy the fuse and replace it yourself in a few minutes \u2014 there are many helpful YouTube tutorials on simple car repairs like this one.<\/li><li>For actuator repairs, some cost more than $700<\/li><li>Therefore, it\u2019s important to know WHAT the issue is to get an idea of HOW MUCH it will cost you.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Does cruise control malfunction trigger the check engine light?<\/strong><\/h3>\n\n\n\n<p>The function of a check engine light or MIL (Malfunction Indicator Light) is to communicate engine or mechanical failures in your vehicle to prevent an accident on the road. The MIL can be lit for simple reasons like the gas cap is loose. Should your CC system fail or run incorrectly, the MIL could light up. Often when there are other failures or engine faults, the MIL will light and the cruise control with a flicker to signal it has been disabled for safety reasons. Once the cruise control or other issues are fixed, all the lights should go back to being turned off.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What makes cruise control not work?
