4 Causes For Ford Auto Start-Stop not Working
The following are some of the most common causes of the Ford Auto Start-Stop system not working:
- Dead battery
If your battery is dead, it can cause the Ford Auto Start-Stop system to stop working. A dead battery can be caused by a variety of factors, including leaving the lights on or leaving the vehicle unused for a long period of time.
- Faulty alternator
The alternator is responsible for keeping the battery charged while the vehicle is in use. If the alternator is faulty, it can cause the battery to drain, leading to the Ford Auto Start-Stop system not working.
- Dirty battery connections
Dirt and grime can build up on the battery connections, preventing the flow of electricity. This can cause the Ford Auto Start-Stop system to stop working.
- Malfunctioning starter motor
The starter motor is responsible for starting the engine. If the starter motor is malfunctioning, it can cause the Ford Auto Start-Stop system to stop working.
How to diagnose the issue
In order to diagnose the issue with your Ford Auto Start-Stop system, you can perform the following steps:
- Checking battery voltage
Use a voltmeter to check the voltage of your battery. If the voltage is low, it could be a sign that the battery is dead or that the alternator is not charging the battery properly.
- Checking alternator output
Use a voltmeter to check the output of your alternator. If the alternator is not producing enough voltage, it could be a sign that the alternator is faulty.
- Checking battery connections
Check the battery connections for any signs of dirt and grime. If the connections are dirty, clean them with a wire brush or sandpaper.
- Scanning for error codes
If the Ford Auto Start-Stop system is not working, it could be due to a problem with the vehicle’s computer. Use an OBD-II scanner to scan for error codes and determine the root cause of the issue.
Ford Auto Start-Stop Not Working: Step-by-Step Solution
If you’re having trouble with your Ford Auto Start-Stop system, don’t worry. Here’s a step-by-step guide to help you diagnose and fix the issue.
Step 1: Check the battery voltage
The first step in diagnosing the issue is to check the battery voltage. You can do this with a voltmeter or multimeter. The voltage should be at least 12.5 volts. If the voltage is less than 12.5 volts, the battery may be dead and needs to be replaced.
Step 2: Check the alternator output
Next, check the alternator output. The alternator should be producing at least 13.5 volts. If the alternator is not producing enough voltage, it may be faulty and needs to be replaced.
Step 3: Clean battery connections
If the battery voltage and alternator output are fine, the next step is to clean the battery connections. Dirt and grime can build up on the connections over time, which can prevent electricity from flowing properly. Clean the connections with a wire brush or sandpaper to ensure that electricity is flowing properly.
Step 4: Scan for error codes
If cleaning the battery connections doesn’t resolve the issue, the next step is to scan for error codes. You can do this with a code reader or scan tool. The error codes can help you determine the root cause of the problem.
Step 5: Replace faulty components
If you’ve found the root cause of the issue, the next step is to replace any faulty components. For example, if the starter motor is malfunctioning, you’ll need to replace it with a new one. If the alternator is faulty, you’ll need to replace it with a new one.
Step 6: Regular maintenance
Finally, make sure to perform regular maintenance on your Ford Auto Start-Stop system to prevent future issues. Check the battery voltage regularly, clean the battery connections regularly, and have your alternator checked regularly to ensure that everything is working properly.
