The LSD in Auto LSD stands for “Limited-Slip Differential,” a traction control system that, when used appropriately, enhances vehicle control by reducing engine output and initiating brakes when one of the drive wheels starts to slip.

When should I use Auto LSD?
Only when wheel slip happens in extremely difficult circumstances, like off-road or in deep snow, should auto LSD be employed. The Auto LSD system should only be used under extremely difficult circumstances. When the car is moving or when the wheels are spinning, don’t turn it on. It must not be used while driving normally.
Increased steering effort may be necessary while utilizing Auto LSD. To maintain control while cornering, you might need to exercise additional caution. The Auto LSD icon will start flashing if the car starts to slip while the system is engaged, signaling that the system is attempting to control the slippage.
How do I turn on Auto LSD?
The “VSC Off switch, which has a picture of a car with two wavy lines behind the wheels and the phrase “Off beneath it, can be used to activate auto LSD. The instrument cluster’s VSC Off and Auto LSD indicators will illuminate when pressed, indicating that the system is activated. Press the “VSC Off button one more to shut down the system.
Traction Control and Auto LSD
When driving under typical circumstances, traction control helps to maximize control. When a wheel slips, it applies brakes to that wheel and limits engine power. Traction Control is disabled while Auto LSD is on. Instead of lowering engine power to propel the wheel forward, auto LSD distributes power to the wheel with the most traction.
Why does Auto LSD automatically shut off?
If the brakes become overheated during operation, the Auto LSD system will immediately cut off. However, it will be restored automatically after a short period. Additionally, the system will turn off automatically when the engine is turned off and stay off when the engine is restarted.

Toyota automatic limited-slip differential: what is it?
Our trucks and SUVs have several features that we may not fully comprehend, and some of them we may not even be aware they exist until a warning light for them shows on the dashboard. What is Auto LSD, what does it do, how does it operate, and do you actually need it? Auto LSD is one of those features about which you might not be entirely certain.
The term “Auto LSD” refers to the Toyota traction control system’s Automatic Limited-Slip Differential, which automatically reduces engine power and applies brakes when it notices that one of the vehicle’s rear wheels is slipping and beginning to spin. The technology only works when the vehicle is in two-wheel drive; four-wheel drive does not activate it.

What would cause the VSC light to come on?
There are numerous things that can go wrong because the VSC system is integrated with the engine control and the brake control systems to control your car’s traction.
A bad accelerator pedal, faulty throttle body, faulty ABS sensors, or a faulty mass airflow sensor are the most typical reasons of a VSC light.
The quickest way to determine what set off your VSC light is to use a diagnostic scanner to read the issue code memory.
C1201:
The two P0 codes point to a leak in the emissions system. Technically, it might be in the charcoal canister or filler neck, but most of the time it’s just a leaky gas cap. Either a worn-out cap or one that was put incorrectly.
The car is instructed to switch on the check engine light and turn off the traction and VSC by the C1201 code. In essence, this code is responsible for alerting you to an issue when the other two appear. Since they are the ones that created it, fixing the other codes should also repair this one.

In snow, does limited slip differential help?
In instances where the traction conditions are not the same for both driving wheels, the limited-slip differential was designed to increase the mobility of motor vehicles. To increase the vehicle’s capacity to escape mud or snow, more driving force is applied to the wheel with the best traction.
What is the lifespan of limited slip differentials?
As it refers to standard work vehicles rather than the countless articles I discovered that are written for performance-oriented dirt track racers, drag racers, drifters, and off-road aficionados, this information seems fairly useful.

How can a limited slip differential malfunction?
Your wheels’ differentials may experience apparent indicators of wear or malfunction. Tyre damage, vibrations, trouble controlling, and grinding gears are the top 5 signs of faulty front and rear differentials. As soon as you notice these symptoms, you may take action and bring your car to a differential-specialist mechanic to have the issue evaluated and fixed before further harm to your vehicle is done.
Damage to Tyres
To minimize unequal wear and tear, your car’s tyres must rotate at various speeds when rounding a corner. Your tires will wear unevenly and have worn, flat tread if your differentials aren’t working properly. Before your tyres deteriorate and you have to replace them as well, having your LSDs examined early will save you money.
Whining Sounds and Vibrations
There are several ways that poor LSDs can result in this. First, the universal joints in your diff may fail, resulting in drive shaft vibrations and a whining sound. Your diffs may also be leaking fluid and causing unpleasant vibrations; in that scenario, they will start to fail very soon.
Control
Since the purpose of LSDs is to improve vehicle control, if you feel like you’re losing some control of your car while driving, there’s a significant probability that something may be wrong with them. Time to have it looked at.
Grinding Gears
You will feel and possibly hear a perceptible grinding of the gears, especially during change, when your differentials malfunction or become faulty. You will hear a whining sound and a low humming sound that intensifies over time.
Why is my Toyota RAV4’s check engine light on?
Your Toyota RAV4 needs immediate care if the check engine light starts to illuminate, so you should bring it in right away. Usually, a serious engine misfire that causes unburned fuel to escape into the exhaust system is indicated by this blinking light.
What does a VSC light that flashes indicate?
You must stop driving the car if the check engine light is flashing. If the engine controller has identified a problem with the engine management system, the check engine light will illuminate steadily. If the defect is likely to harm the catalytic converter, it will flash. The VSC light, which is for the Vehicle Stability Control system, is likely signaling that whatever issue is present, it affects both systems. In other words, you probably only need to do one repair to fix both lights. The warning lights also let you know that the controller has failure codes that can be read by a specialist using the right scanning tools. The diagnosis will be aided by this. If you get in touch with YourMechanic, they’ll send a specialist to your house or place of business to check your car’s controllers for codes and advise you on the best course of action.
