The Toyota Highlander is a high-end SUV that is well-known for its off-roading capabilities. This vehicle has the best off-road performance because it has an AWD system, which improves tire grip.
The AWD technology delivers superior traction on slick and icy conditions by supplying power to all four wheels at once.
What Does the Toyota Highlander’s Check AWD System Mean? Due to a problem with this system, the Toyota Highlander’s dashboard displays the Check AWD system light. The transmission system issue, issues with the wheel’s speed sensors, and the ignition being left on are what cause the warning light to show up on the screen. Attach the OBD-II scanner when the warning light comes on to read the fault codes, which can help you identify the real problem and resolve it.
For the safety of your car, it is essential to fix the AWD system issue. Driving with a check light on raises the possibility of harming other parts.

What does Toyota Highlander’s AWD system check entail?
AWDs aren’t just odd for SUVs. The AWD system is presently being placed on many cars, including sports cars and conventional sedans. In this sort of wheel drive, all four wheels of the car receive power from the engine to enhance grip and allow the vehicle to go along even the slickest of surfaces.
Through what is commonly referred to as a differentialof which there are three: the central, the front, and the rearengine power is divided between both wheel axles. The system that transmits power from the engine to the right axle is the differential. AWD systems increase your car’s safety for a number of reasons, including:
- Your AWD significantly increases your car’s sportiness in a number of ways.
- Your general handling has really improved. Your car’s handling essentially refers to how easily it can be steadied when it is moving down the road.
- Your AWD system is an automatic device that is constantly in operation.
- Driving is possible even when the roads are covered in mud or ice.
Can I drive with AWD light on?
When All-Wheel Drive is deactivated and the drivetrain is switched to Front Wheel Drive for maintenance or if there is a fault with the system, these indicators will be illuminated. Front-wheel drive is a secure mode of operation for the vehicle. With the exception of the red sign below, all these symbols display as yellow/amber.
What does “check AWD system” mean?
If your Fusion has all-wheel drive, you might see a message on the message center in the car that reads Check AWD or AWD Off. If the alert suggests that the system needs to be checked, there may be an issue and you should have the car checked out. If it indicates that the all-wheel drive system is off, it has automatically shut down to prevent possibly damaging itself. Before you may re-engage all-wheel drive, you must have it examined and maintained.
When you utilize the spare tire, the AWD Off warning also appears. The system shuts down on its own because it can’t function with the spare on the vehicle. When you mount the regular tire and wheel once more, it will restart and the message will become clear.
Why is the caution light on for my AWD system?
All-Wheel Drive: In cars with AWD, a blinking indicator light indicates that the system has overheated or broken down and needs repair right away.
What does the Toyota Highlander’s TRAC OFF signify?
“TRAC OFF” Indicator If the vehicle is stuck in fresh snow or mud, the TRAC/VSC systems may decrease power from the engine to the wheels. You may need to turn the system off to enable you to rock the vehicle in order to free it. Press and release the button fast to turn off the TRAC system.
How can I verify AWD?
Checking the engine location is another way to learn what kind of drivetrain your car has. For instance, an AWD or FWD is present if the engine is positioned laterally.
You need to search for the drive lines after determining whether your engine is pointing sideways. Either the front wheels or the back wheels will be the destination. You don’t have an AWD if it solely drives the front wheels. You have an AWD vehicle if it extends all the way to the back.
In RWD, the transmission is located behind the engine, which is facing front. The back wheels receive power from the driveline, which extends from the engine to the back wheels.
Awd will appear to be a front-wheel drive because the engine will be positioned sideways, but there will also be a driveline that connects to the vehicle’s rear wheels. This is so that the engine can power all four wheels while using AWD.
Why does all-wheel drive stop working?
The driver information center may display the All-Wheel Drive Off message (DIC). The all-wheel drive (AWD) system has been turned off and the rear drive system is overheating when the DIC displays this alarm.
If the AWD lamp flashes quickly, what does that mean?
The design specification doesn’t cover more challenging driving conditions like deep mud, rock crawling, or deep snow on SUVs and crossovers with a light-duty four-wheel-drive system that doesn’t have low-range gearing. Continued hard acceleration can cause your vehicle’s transfer case to become extremely hot if you find yourself spinning your wheels without moving ahead or stuck to the point where you are unable to move.
Power is divided between the front and rear axles by the transfer case. If it overheats, it might no longer be able to function as intended, which would make the 4WD light flash. The system itself may have deactivated occasionally so that it can cool down, as shown by the flashing light. It’s a good idea to consult your owner’s manual to determine the precise meaning of the flashing light in this circumstance.
What does the Toyota TRAC off light mean?
The TRAC system turns the traction control on and off to prevent wheelspin and additional downshifting. To turn the TRAC system off, swiftly press and release the switch; the TRAC OFF signal should turn on. Press the switch again to put the system back on.
What does a car’s lock mode do?
Many AWD vehicles include a unique AWD Lock mode that is normally activated by the driver at low speeds for use in extremely slick and difficult situations. When the Lock mode is activated, the ideal torque distribution between the front and rear axles is fixed, rapidly boosting traction. Using the Lock mode informs the AWD system that maximum grip is required, right immediately, rather than waiting for wheelspin or any other trigger to engage it. Use it for navigating treacherous terrain, like deep snow, slick mud, or slippery hills. Your owner’s manual includes all the details, but normally this technology is designed for low-speed use.
What raises the temperature of an AWD?
The High Temp AWD. The electric-controlled coupling in the transfer case was subjected to a severe load, and the multiple disc clutch temperature is now high, according to the Stop Vehicle warning light. The transmission switches to RWD, and the AWD system enters protection mode. It doesn’t act improperly. Automatically restoring AWD and disabling the protective feature, stopping the car and allowing the transmission transfer case fluid to cool.
This can happen if the automobile is brake launched, especially if the car’s HP/torque output has been increased. Your tires must have the same diameter, right?
When your car has power but won’t start, what does it mean?
When a new engine won’t start, the battery is typically at blame. However, a dead battery and an alternator are mostly out of the question if the car is still getting electricity. Some batteries could ship from the factory with a lesser charge retention capacity. This is a manufacturing flaw, and the warranty allows for a replacement.
However, it is simple to believe that the battery is in perfect condition if a car won’t start but still has power. It can be very deceiving, especially if the lights, horn, and other electrical components work well. This is because not all peripherals use the same amount of energy.
But the starter motor needs a lot of energy to crank the engine. It’s possible that a battery nearing the end of its useful life won’t be able to power the starter motor sufficiently. Additionally, some electronic ignition systems start out by using a lot of energy. But since they draw less power from the battery, accessories like lights, horns, and radio systems might function.
Everyone may become confused at this point. So, get your multimeter and examine the battery terminals if your car won’t start but has electricity. It should ideally read 12 volts with the engine off, if not extremely near to it. The battery is on the verge of dying if not.
Start the car, switch on most of the accessories, and read it once more. There should not be a reduction in voltage, and it should increase to 13.5 to 14 volts as you step on the accelerator. If this doesn’t happen, there might be a problem with the alternator. When a car won’t start yet has power, this is the most typical problem.
What may prevent a Toyota from starting?
If the starting is spinning and you are getting power, the fuel system may be the source of the issue.
Electrical Connections The electrical connections in your fuel injection system are many. They are joined at the top, on the cylinder heads, and on the intake airside. Check it whether there is a connection.
Your gasoline system needs to be pressure tested, so test it if you have the tools. Fuel Pump and Relay Check all the electrical connections to the fuel pump with a circuit tester. Turn the key to ON. If there is a current, the pump is not the problem. Verify the fuse if there is no current. Replace the gasoline pump relay if the fuse is functioning properly. (This article has further information about replacing the fuel pump.)
Fuel FilterThe fuel filter could be blocked even if your fuel pump is functioning. Replacing it if it’s clogged should be a part of your maintenance schedule. (More about gasoline filters in this article).
You can carry out each of these recommendations in your driveway at home. With the right tools, you can conduct more thorough tests.
- Poor injectors can prevent the engine from starting.
- ECU or MAFThe computer in your automobile can be broken. You must contact your dealership for help if that is the situation.
- Cold Start ValveA damaged cold start valve may prevent your automobile from starting while the engine is cold.
- Starting Verify that your starter is securely fastened because it can be loose.
- Your car may not start if the flywheel or ring gear has worn teeth. When they are involved, they will shriek.
While any one of these elements is typically the cause of a car not starting, you can encounter a circumstance where it is outside the purview of these problems. If you have performed all the necessary checks and the vehicle still won’t start, you might need to speak with your nearby Toyota dealership.
