Troubleshooting Steps for Subaru Ascent Push Button Start Failure
Experiencing a push button start failure in your Subaru Ascent can be frustrating, especially when you rely on this feature for convenience and ease of use. However, before seeking professional assistance, there are several troubleshooting steps you can take to identify and potentially resolve the issue. Understanding the underlying causes of a malfunctioning push button start system is essential, as it can save you time and money.
To begin with, it is crucial to ensure that the vehicle is in the correct mode for starting. The Subaru Ascent requires the transmission to be in the “Park” or “Neutral” position for the push button start to function properly. If the vehicle is inadvertently in “Drive” or “Reverse,” the system will not engage. Therefore, double-checking the gear position is a simple yet effective first step. If the gear is correctly positioned and the push button still does not respond, the next step involves examining the key fob.
The key fob plays a vital role in the push button start system, as it communicates with the vehicle’s electronic systems. If the key fob battery is low or dead, it may not send the necessary signal to start the engine. To troubleshoot this, try using a spare key fob if available. If the spare fob works, it is advisable to replace the battery in the original fob. Conversely, if the spare fob also fails to start the vehicle, the issue may lie elsewhere.
In addition to checking the key fob, it is important to inspect the vehicle’s battery. A weak or dead battery can prevent the push button start from functioning. To assess the battery’s condition, look for signs of corrosion on the terminals or a dimming dashboard display. If the battery appears to be the culprit, jump-starting the vehicle or replacing the battery may resolve the issue. However, if the battery is in good condition, further investigation is warranted.
Another potential cause of push button start failure could be a malfunctioning brake pedal switch. The push button start system requires the brake pedal to be depressed for the engine to start. If the brake pedal switch is faulty or misaligned, it may not register that the pedal is being pressed. To test this, ensure that the brake lights illuminate when the pedal is pressed. If the lights do not activate, the brake pedal switch may need adjustment or replacement.
Furthermore, it is essential to consider the possibility of a blown fuse. The push button start system relies on various electrical components, and a blown fuse can disrupt the entire operation. Consulting the vehicle’s owner manual will provide information on the location of the relevant fuses. If a fuse is found to be blown, replacing it may restore functionality to the push button start system.
If all these troubleshooting steps fail to resolve the issue, it may be time to consult a professional mechanic or visit a Subaru dealership. They possess the specialized tools and knowledge to diagnose more complex problems, such as issues with the vehicle’s ignition system or electronic control unit. In conclusion, while a push button start failure in your Subaru Ascent can be inconvenient, following these troubleshooting steps can help identify the problem and potentially lead to a solution. By systematically checking the gear position, key fob, battery, brake pedal switch, and fuses, you can narrow down the cause of the malfunction and take appropriate action.
