Push-button start has become popular in modern vehicles, including the Jeep Cherokee. However, like any other technology, push button start may sometimes malfunction or fail to work.
Your Jeep Cherokee push button start may not work if the car’s battery is dead or has a low charge. A quick way to resolve this issue is to Jump start the car’s battery or recharge the battery using a battery charger to get the vehicle running again.
In this article, we will explore the causes and solutions for Jeep Cherokee push button start issues and ways to prevent this issue from occurring.
What is Push Button Start in Jeep Cherokee?
Push button start is a modern technology feature in many vehicles that allows the driver to start the engine without using a traditional key. Instead of inserting a key into the ignition and turning it to start the engine, the driver pushes a button located on the dashboard or center console of the vehicle.
Push button start technology uses a key fob, which communicates with the car’s onboard computer to allow the engine to start when the button is pushed. The key fob contains a unique code recognized by the car’s computer, which verifies the code and enables the engine to start.
Push button start is often coupled with keyless entry, which allows the driver to unlock and lock the vehicle’s doors by simply approaching the car with the key fob in their pocket or purse. This technology has become increasingly popular in recent years due to its convenience and ease of use.
Causes of Jeep Cherokee Push Button Start Problems
Let’s explore some of the most common causes of this problem:
Push button start system requires sufficient battery power to start the engine. A weak or dead battery prevents the push button start system from engaging the engine. To check if the battery is causing the issue, try turning on the car’s headlights or interior lights. If the lights are dim or do not turn on, it indicates a weak or dead battery.
The key fob is a critical component of the push button start system, and if it is damaged, low on battery, or has a weak signal, it may not be able to communicate with the car’s computer system. This prevents the push button start from working properly.
Push button start system requires the brake pedal to be depressed to engage the engine. If the sensor that detects the brake pedal is not functioning correctly, it will prevent the engine from starting. To check if the brake pedal sensor is causing the issue, ensure that the brake pedal is fully depressed and that no obstructions prevent it from functioning properly.
The ignition switch provides power to the starter motor and other electrical components needed to start the engine. A malfunctioning ignition switch prevents the push button start system from engaging the engine.
This start system relies on software to communicate with the car’s computer system and start the engine. Software glitches cause the system to malfunction, preventing the engine from starting. It’s also important to note that software glitches sometimes signify a larger underlying issue, so it’s recommended to have the car thoroughly checked by a qualified mechanic to identify it.
