It will be necessary to do a few things after changing the battery in your Ford Focus in order to allow the ECU to recognize the new battery.
Additionally, you may be able to prolong the life of your battery since your alternator isn’t overcharging it, which can cause a new battery to wear down faster.
How To Reset The Battery Light On Ford Focus?
It is necessary to put the car in the on position without the engine running to reset the car. First, make sure the dipped beam is on. Then, press the hazard button three times, followed by the rear fog light button five times.
There should be three flashes of the battery icon on the dashboard after that. As long as the light flashes, you can begin driving your car with a new battery registered.
Fix The Light Issue
When the system detects the fault again, the battery light will turn back on, so resetting it without resolving the underlying issue is unlikely to be helpful.
After the issue is fixed, the light should automatically disappear. You might be able to get it to go away if you drive your car for a few miles if it doesn’t start right away.
OBDII Scanner Method
In Focus, clearing the codes with an OBDII scanner is the proper way to reset the battery light.
By connecting a diagnostic device and deleting all the error codes related to the charging system, you can manually turn off the warning light if it doesn’t turn off automatically.
Make Sure The Battery Is Disconnected
The battery light in Focus may be reset by disconnecting the battery for a few minutes if you don’t have a diagnostic device. Start by removing the cable from the battery’s negative terminal, then remove it from the positive terminal.
To drain all residual electricity from the system, press the horn button a few times and turn on the headlights without the battery connected. The positive cable should be connected first, then the negative cable after about 15 minutes.
What Is The Time It Takes For A Battery Light To Reset?
In some cases, it can take a while for the light to reset after replacing the battery. The light may remain on for several hours or even days, depending on the car.
As long as the battery is not damaged, the light should not come back unless another malfunction triggers it.
Ford Check Charge System: What Does It Mean?
In every car, there is a check charge system. This ensures that the battery in your car is charged properly. However, it is possible for the battery to become overcharged or undercharged if this system does not work properly.
Keeping your battery charged can also extend its lifespan. Of course, the most important part of every car is the engine, but many people are unaware of how important it is, so their cars aren’t running as efficiently as they could be.
There are several problems that can be detected by the check charge system, including shortened battery life, decreased performance, and even complete engine failure. Therefore, your car’s check charge system should be checked regularly in order to prevent these problems.
Where Is This System Located?
A typical location for this system is under the hood, where it is easy to reach. To ensure your car’s system is functioning properly, however, you may want to take it to a professional mechanic if you are uncomfortable working with electrical components.
Your vehicle’s instrument panel may display a Ford check charge system message. Having a qualified technician check the charging system is the best way to determine if it is working properly.
This message may also be accompanied by a warning light on the dashboard. A dead battery can leave you stranded if you don’t take action as soon as possible if you see this message.
Tips For A Functional Battery Light
- Pay attention to your car’s battery light if it comes on! Make sure you take action immediately if you don’t want to be stranded with a dead battery.
- Nevertheless, here are some tips for maintaining the battery light on your car and avoiding such a situation:
- Maintain your car’s battery with a battery maintainer. You will be able to extend the battery’s life this way.
- Ensure that the electrical system of your car is working properly. Ensure that all connections are tight and clean.
- Make sure your car’s battery is regularly checked. Checking the voltage with a voltmeter is an excellent way to do this.
- What is the reason for my battery light still being on after replacing the battery?
- The battery light on your car still illuminates even after you replaced the battery; here are a few possible reasons:
- It will stay on if the charging system isn’t functioning properly, and the battery can’t be charged.
- It’s also possible that the charging system is malfunctioning. For example, a bad alternator, a loose connection, or a blown fuse could cause this problem.
- There may be a problem with the new battery not being seated properly. Maintain a clean and tight battery terminal.
The Bottom Line
Battery lights are important warning systems on cars. However, to find out what is wrong with the vehicle, the driver should take it to a mechanic when it comes on.
The driver can try reconnecting and disconnecting the battery to reset the light. Unfortunately, sometimes the problem is worse than this, so this isn’t always successful.
