Certain functions in your Subaru vehicle may experience disruptions following a battery change. Therefore, it is crucial to be prepared to perform a Subaru reset after battery replacement.

During the battery replacement process, the Subaru car’s computer loses electric current for a period of time. Consequently, the data stored in the computer’s memory is erased.

The purpose of the reset is to recover the lost information and restore the vehicle’s functionality to its previous state prior to the battery change.

Subaru Reset After Battery Change

In resetting your Subaru after a battery change, there are five important steps that you must follow diligently.

Step 1: Determining the Reset Requirements

To begin the process of resetting your Subaru after a battery change, start your car and inspect the dashboard for any erroneous warning lights. Test various features that rely on the car’s computer, such as the power window control system, to ensure proper functionality.

Step 2: Verifying Connections and Functionality

Check if the lighting system, radio presets, and air conditioning are operating correctly. If everything functions as expected, it indicates that the battery change did not affect the car’s computer. In such cases, a reset may not be necessary, as there may be a power backup mechanism or minimal power loss during the battery swap.

However, if any features are not functioning properly, take note of them and proceed with the reset.

Step 3: Allowing Automatic Resets

Certain aspects of the car’s settings can automatically reset as you continue to use the vehicle. This includes engine air/fuel mixture settings, gear shift positions, and more. Simply operate the car normally, and it will detect and adjust these settings automatically.

Step 4: Manual Input of New Settings

Some settings may require manual entry. For instance, radio frequency selections can be easily inputted. On the other hand, adjusting odometer readings may involve accessing the memory chip via a computer or manipulating the fuse box by identifying and reinserting the relevant fuses.

If you encountered inaccurate error codes, focus on clearing them by turning the vehicle on and off multiple times or utilizing an OBD scanner.

Step 5: Verifying New Settings

Turn on the car and observe the dashboard to ensure that the new settings are functioning correctly. Confirm that error codes have been cleared, test the power windows for proper operation, and check the radio pre-selections. Additionally, take the vehicle for a drive to ensure that the computer-controlled engine elements are functioning as expected.

To avoid the need for a complete reset, consider employing methods to preserve the car’s computer memory during a battery change. This can be achieved by using a power backup device or memory saver, or by utilizing another battery and jumper cables. Taking these precautions can help prevent potential issues and expensive repairs in the future.

Common Issues Arising After Subaru Car Battery Replacement

  1. Non-responsive Power Windows The functionality of power windows relies on the car’s computer system. During a Subaru battery change, if the computer loses power, it can result in power windows not functioning properly.

Fortunately, in most cases, this issue resolves itself after installing the new battery and giving it some time to stabilize.

If the problem persists, you may need to access the fuse box, locate the node responsible for the power windows, remove it, and then reinsert it to see if it resolves the issue.

  1. Blank Fuel Economy Panel After a battery change, you may encounter a blank fuel economy panel, preventing you from seeing fuel consumption or tank levels.

To address this, check the lower left side of the steering wheel for the info switch. Toggle the switch to attempt to reactivate the fuel economy panel.

  1. Loss of Radio Presets It is common for radio presets to be lost during a Subaru battery change. However, you can easily resolve this issue by performing an auto-search or manually entering and saving your preferred radio frequencies to restore your preset stations.
  2. Inoperative Wipers At times, a Subaru battery change can temporarily disable the wipers. Fortunately, this problem often resolves itself after a few minutes following the battery replacement.

If the issue persists, accessing the car’s fuse box and locating the wipers’ node may allow you to resolve the problem by removing and reinserting it.

  1. Tire Pressure Units Change Changing the Subaru battery may result in the tire pressure units switching from PSI to kPA, causing confusion.

To rectify this, navigate to the dashboard preferences and switch back to PSI or your preferred unit of measurement.

  1. Inaccurate Error Codes After a battery change, you may encounter inaccurate error codes related to ABS, brake lights, VDC, and other systems. One troubleshooting method involves turning the vehicle on and off three times to see if it resolves the issue.

Alternatively, you can connect a scanner to the vehicle’s OBD port and use it to clear the error codes individually.
