Should the car’s computer be reset following a battery change?
Great inquiry. You can use an OBD-II scanner or unplug and replug the positive battery terminal to reset the ECU.
The bolt on the battery terminal needs to be loosened using a tiny wrench for the first technique. Just unplug the wire and allow the vehicle to sit for at least five minutes. After that, secure the cable again and tighten the clamp. Check to verify if the dashboard lights are still present after starting your car.
An OBD-II scanner is required for the second technique. It should be connected to the OBD-II port under the steering wheel of your car. Error messages will be presented. The option to remove the errors from the system will then be presented to you. Start your automobile after that to see if the error lights are still on.
Remember that if you continue to have error symptoms after changing your battery, it may indicate that your ECU is having trouble or that there is another problem entirely. Because the majority of ECUs are self-learning, they should reset once they recognize that a fresh battery has been placed.
If you’re stuck, ask a mechanic for help with the diagnosis. You should expect to pay $50 to $150.

Before you take this approach, keep in mind that there are certain drawbacks to this way of turning off your check engine light. If your car was made after 1996 and you have access to one of these tools, such as this one available on Amazon, you can also use it to reset the fault codes if you’d prefer not to deal with those.

The battery management system of the automobile won’t function properly without battery coding, and several vehicle operations may stop. The worst-case situation is that it might even be impossible to start the car.
Before beginning any work, a battery support unit should be installed. This keeps the electronic memory of the car. The system of the car could reset to the factory default if there isn’t a support unit.
Since the coding portion of this process cannot be skipped, it is crucial to follow the installation process from beginning to end.
To keep codes and information about the instrument display, connect a battery support unit, such as the BAT490. Throughout the process of installing the battery, this should be connected.
