Auto start services are a crucial part of your vehicle’s operation, but they can sometimes malfunction and stop working. This can lead to a variety of issues, including difficulty starting your car, reduced fuel economy, and even damage to your engine. In this article, we’ll explore the common reasons why auto start services stop and provide a step-by-step guide on how to troubleshoot and fix them.
Understanding Auto Start Services
Auto start services, also known as auto start-stop systems, are designed to improve fuel efficiency by automatically turning off the engine when the vehicle is at a standstill, such as at traffic lights or in heavy congestion. When the brake pedal is released, the engine restarts automatically.
Why do auto start services stop working?
There are several reasons why auto start services might stop working, including:
- Battery Problems: Auto start-stop systems rely on a healthy battery to power the engine restart. A weak battery can cause the system to shut down.
- Starter Issues: The starter motor is responsible for cranking the engine. If the starter is faulty, the auto start-stop system won’t be able to restart the engine.
- Sensor Malfunctions: Various sensors monitor the vehicle’s status, including the brake pedal position, engine temperature, and battery voltage. A malfunctioning sensor can trigger the auto start-stop system to disable.
- Software Glitches: The auto start-stop system is controlled by the car’s computer. Software glitches or updates can sometimes cause the system to malfunction.
- Environmental Conditions: Extreme temperatures, particularly hot weather, can sometimes affect the performance of the auto start-stop system.
- Vehicle Load: Heavy loads, such as a full passenger load or a trailer, can put extra strain on the battery and engine, leading to the auto start-stop system disabling.
How to Troubleshoot and Fix Auto Start Services
1. Check the Battery
- Battery Voltage: Use a voltmeter to measure the battery voltage. A fully charged battery should read around 12.6 volts. If the voltage is low, it may be time to replace the battery.
- Battery Terminal Connections: Ensure the battery terminals are clean and tightly secured. Corrosion can prevent proper electrical flow.
2. Inspect the Starter
- Starter Motor: Listen for any unusual noises coming from the starter motor when you attempt to start the engine. A clicking noise could indicate a faulty starter.
- Starter Relay: The starter relay is an electrical switch that activates the starter motor. If the relay is faulty, the starter won’t engage.
3. Examine Sensors
- Brake Pedal Position Sensor: This sensor determines when the brake pedal is depressed. A faulty sensor may prevent the auto start-stop system from working.
- Engine Temperature Sensor: The auto start-stop system may disable if the engine is too hot or too cold. Inspect the engine temperature sensor for any damage or signs of malfunction.
4. Check Software Updates
- Computer System: Take your vehicle to a qualified mechanic to check for any available software updates for the car’s computer system. Updates can fix bugs or improve performance.
5. Address Environmental Factors
- Temperature: Avoid using the auto start-stop system in extreme temperatures if it seems to be malfunctioning in those conditions.
6. Reduce Vehicle Load
- Heavy Loads: If the auto start-stop system is disabled when you’re carrying a heavy load, consider reducing the load to see if it resolves the issue.
