Does it Require Subaru Reset After Battery Change?

Car battery replacement involves many considerations, such as whether you have the right tools, if you need to disconnect the negative terminal, or if you should reset the car’s computer. This article discusses if a Subaru battery reset is required after replacing the old battery.

The Subaru reset is a procedure that resets your car to factory settings. It’s similar to doing a factory reset on your computer, clearing all the data and then reloading it with new settings. It can change the battery or fix an error code in the vehicle’s system.

Do you have to reset anything after changing the battery?

Yes, you need to reset your settings after changing the battery. Resetting Subaru after changing the car‘s battery clears any error codes stored in the old battery, preventing future issues with your car and keeping your driving experience smooth. However, note that doing a reset clears all your personal preferences within the car’s settings, such as the radio station presets or seat positions. So, if you’ve been driving around for months or years, be prepared to adjust it again after the reset is complete.

How do you reset the ECU on a Subaru?

The process of resetting the Electronic Control Unit (ECU) varies depending on the age and model of your Subaru. However, most Subaru models utilize a ‘Clear Memory’ process to reset the ECU. To clear memory on your Subaru, you will need to locate the ECU reset button, typically found near the dashboard. Once you have located the reset button, press and hold it for a few seconds until the indicator light turns on or off, then release the button to complete the process.

Another way to reset it is by using a diagnostic tool or scanner. It is typically done by plugging the scanner into your car’s diagnostics port and following the on-screen instructions.

Once you have completed the Subaru Reset, driving your car around is crucial to ensure that all systems function well.

If you still have trouble locating your Subaru computer reset button, consult your Subaru’s manual for more information. If you are still experiencing issues after resetting your ECU, please don’t hesitate to get in touch with a certified Subaru mechanic for assistance.

How do you reset the battery on a 2017 Subaru Outback?

The most popular method for resetting the system on a Subaru Outback is disconnecting the cable that connects the battery to the vehicle. Please follow the procedure below:

  1. First, access the battery on the right side of the vehicle’s engine compartment, which is close to the firewall.
  2. Take off a cover made of black plastic material.
  3. Remove the negative cable and wait a few minutes before removing the positive line. It will allow any built-up energy to dissipate. Be careful not to touch the battery terminals with any metal objects, as this could create a spark and cause an injury.
  4. After 15mins, reattach the cables back to the terminals. Make sure that the clamps are tight.

You could also use a scanner to reset the battery on a Subaru. This device is plugged into the OBDII port and will reset the system for you. If unsure, it is always best to ask a certified technician to help reset the battery on your Subaru Outback. This will ensure that it is done safely and correctly.

Will touching battery cables together reset the car’s computer?

Programming or settings may be lost if the battery is disconnected for a long time. Touching the battery cables together may erase any programming set or saved.

However, this is not advisable to reset the system by yourself since there are possible dangers when touching battery terminals together, causing a spark that starts a fire. If you’re brave enough to try it, make sure you have a fire extinguisher close by in an emergency. Be very careful when doing this, and always use caution. Nonetheless, taking your car to a certified technician is highly recommended.

What are the symptoms of a bad ECU?

There are a few symptoms of a bad Electronic Control Unit (ECU). One is that the car will not start, or it will start but then die soon afterward. Another one is that the engine will misfire or run rough. If the ECU is bad, you could notice your fuel economy has decreased, or the check engine light is on. If you are experiencing any of these symptoms, you need an ECU or Subaru battery replacement. Ensure that the ECU you’d replace is not counterfeit. So, buy from a trusted and reputable dealer.


While there is no one-size-fits-all procedure for resetting the car’s computer, it is advisable to take your Subaru in for maintenance after the battery change. It will ensure that all vehicle systems are properly calibrated and functioning. In addition, if you are suffering any symptoms of a bad ECU, don’t wait to replace it. The longer you delay, the more damage you could do to your car. Get it fixed as soon as possible so you can enjoy a smooth-running engine once again.
