OBDII scanner method
Clearing the codes with an OBDII scanner is the correct technique to reset the battery light on a Corolla. After resolving the problem, if the warning light doesn’t go off automatically, you’ll need to manually turn it off by connecting a diagnostic device and then erasing all the incorrect codes pertaining to the charging system.
Disconnect the battery
If you don’t have a diagnostic tool, you might be able to reset the Corolla’s battery light by unplugging it for a short while. Before removing the cable from the battery’s positive terminal, disconnect it from the negative terminal. To remove any remaining electricity from the system when the battery is unplugged, turn on the headlights and repeatedly push the horn button. Reconnect the batteries in reverse order, starting with the positive cable and moving to the negative cable, after around 15 minutes.
How can I repair the dashboard battery light?
Let’s now discuss the battery light on your car! It can indicate that the battery needs to be changed. However, a minor (and readily fixable) problem like rust or loosened clamps could also be the cause of the light. Put on some safety gloves, review your owner’s manual, and then cautiously carry out the battery troubleshooting methods below.
- Battery terminals should be cleaned. Your automobile battery light may come on if you have seen considerable corrosion or other dirt around your battery terminals. Fortunately, cleaning your battery connections with basic home products and a little elbow grease is simple and affordable. Just take off the terminal covers, unplug the battery cables, and thoroughly scrub the terminals.
- For rusting, look. In some vehicles, regular operation fumes can lead to rust buildup on top of the battery terminals, especially in warm climates or during the summer. Remove any covers from the terminals on top of your battery and inspect them for corrosion. Corrosion is present if you notice a white or greenish substance on the top of the battery or near the terminals. The transmission of electricity from the battery to the rest of your car can be hampered by battery corrosion, despite the fact that it is a typical occurrence. Battery corrosion should not be handled with bare hands as it may irritate the skin. Go to our next troubleshooting advice instead.
- Make the cable clamps tighter. A weak connection between your battery and the connections that connect to it can occasionally cause your car’s battery light to illuminate. Make sure the clamps are firmly attached to the battery connections when the hood is open. If you see that the clamps are not snug around the terminals, tighten them with a small wrench or a pair of pliers. For detailed instructions pertaining to your vehicle’s make and model, refer to your owner’s manual.
Why is the battery light still on after a new battery was installed?
At our store, we get this question a lot. The new battery’s improper charging is the most frequent cause of the battery light turning on after a replacement. The engine might not start if the new battery is not fully charged since it won’t be able to supply the starter with the necessary voltage. It’s also possible that the replacement battery is the wrong size for your vehicle. The replacement battery won’t be able to supply the starter with the necessary voltage if it is too tiny. And last, it’s conceivable that the fresh battery has a flaw. The engine won’t start if the new battery has a problem since it won’t be able to supply the starter with the necessary voltage.
Added to that An glowing battery indicator on a car’s dashboard is typically an indication that the charging system isn’t working properly. A loose or corroded battery cable, a fault with the alternator or voltage regulator, or damaged cells or plates inside the battery could all be to blame for the light.
Why is the Toyota Corolla’s battery light on?
Turn off your accessories when the battery warning light on your Toyota Corolla comes on to prevent further battery depletion. The warning light typically indicates a problem with the alternator, which forces you to run entirely on battery power.
Why does the battery light remain on even after the alternator and batteries have been replaced?
Hello. It’s probable that the weak battery you’ve been experiencing is a result of the issues you’ve been having with the faulty alternators. As a result, the Battery Light would turn on. It’s also conceivable that the alternator fuse or fusible link for the charging system are malfunctioning.
I would advise you to have an electrical system examination and battery test performed by a trained technician, such as one from YourMechanic, in order to identify the issue and perform the required repairs.
How can I restart my automobile once the battery has been changed?
- The check engine light will illuminate if there are any problems, and the electronic control module is probably to blame.
- To allow the engine control systems to detect any potential issues, drive the automobile for at least 10 kilometers.
- You’re good to go if the light doesn’t turn on.

What could activate a battery light?
The battery warning light should briefly illuminate each time the car starts, then switch off after a short while. This system test shows that the battery light on the dash and any other charging system components being watched are functioning as they should.
If there is a problem with the charging system, the warning light for the battery will continue to be on. When troubleshooting if this happens, there are a lot of possible causes to look into.
Check your owner’s manual for basic advice before working with electrical systems because safety is crucial. Wearing rubber gloves will protect you from shock, and wearing goggles or gloves will protect your eyes from splashes of battery acid. Before cleaning or carefully inspecting the battery, disconnect it.
Other signs that the battery is having problems charging include weak headlights, a slow-moving clock, or malfunctions with the air conditioner or radio.
#1Bad Battery
A typical 12 volt battery lasts 3 to 5 years. Although some manufacturers claim that their batteries have a longer lifespan, this is not something that should be expected.
Each of the six cells in these traditional batteries has a lead dioxide plate and a lead plate submerged in an electrolyte solution of sulfuric acid. The electrolyte solution may leak as the cells or plates deteriorate with time. The battery must be replaced if this occurs.
The battery may also be unable to accept or keep a charge due to poor wiring or poor grounding.
#2Bad Alternator
Using a multimeter, it is rather simple to examine the alternator’s performance. The ideal voltage range is 13.6 to 14.6 volts. The battery light is activated if the voltage is less than 12 volts, and the alternator probably has to be replaced.
If the voltage regulator isn’t functioning properly, which is the component that restricts the output to a safe level of 14.5 volts, that could potentially be the problem.
Driving with the battery light on is permissible.
Driving while your car’s battery light is on is dangerous. Your car may lose power if problems with the battery or alternator that trigger the battery light exist. Your car won’t work normally under certain circumstances.
You must make sure the battery is always functioning properly because it is a crucial piece of automotive equipment. Investigate the issue if you’re unsure of why your battery light is on. Additionally, if the issue continues, have your automobile checked out and fixed by a licensed mechanic.

Can the battery light turn on with a blown fuse?
It can, really. The electrical supply from the alternator to the battery and vice versa will change if the safety fuse blows. The battery light will turn on right away when the power supply between these two parts is cut off by an automatic signal.
What is the turnaround time for the battery light to reset?
After some research, I discovered that the problem can be fixed by doing a battery reset. The car must remain still for at least eight hours before the message can be reset automatically.
How can you identify if the problem is with the battery or alternator?
In its most basic form, starting and operating an engine is a 3-step procedure. The battery first jolts the starter with power. The alternator is then activated when the engine is started. The alternator then charges the battery to end this cycle.
Bypassing the battery’s function and jump-starting your vehicle, you can use the process of elimination to identify the offender. The alternator is probably not keeping your battery charged if the engine starts but soon shuts off. If your automobile can be started and maintained by a jump start, but it won’t restart on its own power, you most likely have a dead battery.
What does a light with a solid battery mean?
A charging issue with your automobile battery is indicated by the battery light on the dashboard. If the indicator comes on and stays on, your alternator could not be producing enough voltage to charge the device. A faulty alternator, damaged battery cells, or a broken alternator belt are examples of common causes.
If your battery light is on while you’re driving, you’ll have between 30 and 60 minutes before your car might start stalling.
If your car’s battery is dead, it might not start or start slowly, have dimmed or flickering lights, or have a problem with the sound system. The alternator is broken or not recharging your battery if it stalls while you’re traveling or stops abruptly.
Consider shutting off all the appliances, lights, and other devices that could deplete your battery. Stop the car and let it cool down if the issue continues. Drive right over to your technician to have them have a look if it still doesn’t function.
You must visit a professional if your battery light remains on even though your automobile appears to be operating normally. The battery’s remaining energy is being depleted by your car, which will eventually shut off.
What symptoms indicate a faulty alternator?
As was already noted, if your engine is difficult to start, your alternator may not be charging the battery. As a result, when you turn the key in the ignition, all you’ll hear is a clicking noise rather than your engine’s purring sound.
On the other hand, if your car repeatedly stalls out while you’re driving, it can mean that the alternator isn’t supplying the spark plugs with enough power to keep the engine running.
