Troubleshooting Steps for Non-Responsive Push Button Start in Subaru Forester

Experiencing a non-responsive push button start in a Subaru Forester can be frustrating, especially when you rely on this feature for convenience and ease of use. Fortunately, there are several troubleshooting steps you can take to identify and potentially resolve the issue. First and foremost, it is essential to ensure that the vehicle is in the correct mode for starting. The Subaru Forester requires the gear shift to be in the “Park” position for the push button start to function. If the vehicle is in “Neutral” or “Drive,” the system will not engage. Therefore, double-checking the gear position is a crucial first step.

If the gear shift is indeed in the “Park” position, the next step involves examining the key fob. The push button start system relies on a properly functioning key fob to communicate with the vehicle. Begin by checking the battery in the key fob, as a weak or dead battery can prevent the system from recognizing the fob. Replacing the battery is a simple process that can often resolve the issue. After replacing the battery, try pressing the push button start again to see if the vehicle responds.

In addition to the key fob battery, it is also important to ensure that the key fob itself is functioning correctly. If the fob has been damaged or exposed to water, it may not work properly. In such cases, testing the fob with a spare, if available, can help determine whether the original fob is the source of the problem. If the spare fob works, it may be time to replace the damaged one.

If the key fob appears to be in good condition and the battery is fresh, the next area to investigate is the vehicle’s electrical system. A blown fuse can disrupt the push button start functionality. Consulting the owner’s manual will provide information on the location of the fuse box and which fuse corresponds to the push button start system. Inspecting and replacing any blown fuses can often restore functionality.

Moreover, it is advisable to check the vehicle’s battery itself. A weak or failing battery can lead to insufficient power for the push button start system to operate. If the battery is more than a few years old or has shown signs of weakness, such as dimming lights or slow cranking, it may be time for a replacement. Testing the battery with a multimeter can provide insight into its health; a reading below 12.4 volts indicates that the battery may need charging or replacement.

If all these steps have been taken and the push button start still does not work, it may be necessary to consider more complex issues, such as problems with the ignition system or the push button start module itself. In such cases, consulting a professional mechanic or visiting a Subaru dealership may be the best course of action. They can perform a thorough diagnostic to identify any underlying issues that may not be immediately apparent.

In conclusion, while a non-responsive push button start in a Subaru Forester can be a source of inconvenience, following these troubleshooting steps can help pinpoint the problem. By checking the gear position, inspecting the key fob and its battery, examining the vehicle’s fuses and battery, and seeking professional assistance if necessary, you can work towards restoring the functionality of this essential feature.
