How to Reset Mercedes Computer After a Battery Change
If you have just replaced the battery in your Mercedes-Benz after a Peoria Mercedes repair, you will need to reset the computer. This is a very easy process and can be done in just a few minutes, but it can seem a daunting task if you lack experience with this sort of thing. In this article, we will walk you through the steps necessary to reset the computer on your Mercedes.
Changing Your Mercedes Battery
To start, you should make sure the car is off and that all accessories are turned off. Now open the hood of your Mercedes and locate the battery. You should see a red positive terminal and a black negative terminal. On the negative side, you will find multiple yellow tabs that are connected to the car’s computers. You should remove these as you will be disconnecting the battery entirely.
Next, use a wrench or socket to loosen the nuts and bolts on the negative terminal. You can then unplug the negative cable and remove it from the battery. Follow this with the positive side, using the same process of loosening the nuts and bolts, unplugging it from the battery, and removing it from the car.
At this point, you should double-check to make sure that the battery is completely disconnected. If all looks good, you can then start to remove the old battery by unscrewing its mounts and lifting it out of the vehicle.
Once you have a new battery, you need to begin the process of re-installing it. Start by positioning the new battery in the same place as the old one and reconnecting all of the positive and negative cables. Tighten the nuts and bolts back into place and make sure that all the connections are secure.
Resetting the Computer
With the battery re-installed, it’s time to reset the computer. Start by plugging a diagnostic scanner into the OBD II port located on the driver’s side of the vehicle; this will allow you to access the computer and reset it.
First, access the main menu and select the “Settings” option. From here, you should see several different options to choose from. Scroll down until you find the “Reset Computer” option and select it. After selecting the reset computer option, a prompt will appear asking you to confirm the action. Follow the on-screen instructions to complete the reset process.
Once you have finished resetting the computer, it’s important to do a few additional steps to ensure that the reset was successful. First, start the car and let it idle for about 10 minutes to make sure all the computer settings have been properly updated. After this time has passed, restart your car and do a quick inspection of any warning lights on your dashboard. If any of the lights are still illuminated, you may need to take your car to a certified mechanic for further diagnosis and repair.
