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.

Auto limited-slip differential: what is it?
A limited-slip differential, sometimes known as an LSD, distributes torque among the driven wheels to enable quicker cornering. Through the prevention of wheelspin and the enhancement of traction, this enables the car to utilize the output of its engine as effectively as possible.
Toyota slip indication light: what is it?
The slip indicator flashes to show that Vehicle Stability Control (VSC) and/or Traction Control (TRAC) are active in order to restore traction if the system detects that your tires may be slipping. If the light continues to illuminate, there may be a problem with the TRAC/VSC system as a whole.
Is there a limited slip in tundra?
Automatic Limited-Slip Differential (Auto LSD) is a limited-slip differential that comes standard on all Tundra models. Auto LSD provides brakes to individual unresponsive wheels individually rather than physically managing slip.
What does the Toyota Tundra’s VSC off mean?
The VSC Off system is an electronic technology created to assist you in keeping control of your Toyota car in challenging circumstances. In the event that this feature is disabled, you will be able to drive your car as you normally would.
Why is my Tundra’s traction control light on?
ABS isn’t working: ABS (anti-lock braking system) and traction control frequently share a control module and an internal self-diagnostics system. As a result, the traction control light may occasionally come on if there is a problem with the ABS. Both the Traction Control and ABS lights will be on if this is the situation.
Broken wheel speed sensors: Wheel speed sensors measure how fast each wheel is moving and are often found in the wheel bearing assembly. The traction control module decides whether or not to shift power based on the information the sensors pass along. Wheel speed sensors may get clogged or damaged and cease to function, making it impossible for the traction control module to determine when to turn on the system.
Faulty traction control module: The traction control module, which is once again frequently shared with the ABS, may malfunction or completely fail, rendering the system inoperable.
How does a Toyota Tundra’s VSC light get reset?
Vehicle Stability Control, or VSC as it is commonly known, is the stability control system used in Toyota automobiles. By lowering or eliminating the power provided to your wheels, stability control aids in the maintenance of traction and control in your vehicle. By automatically providing brake pressure to up to three wheels, it achieves this. The system’s main objective is to keep your car traveling in the direction of its wheels. Since 2012, at least in the USA, it has become a necessary safety requirement. Naturally, VSC OFF denotes that your Toyota’s stability control is turned off.
VSC Light Easy Fix
Depending on the model year of the Toyota, a button with the same icon as the light in your gauges will be located either next to your shifter or next to your steering wheel. When you’ve found it:
- Ensure that you have come to a complete stop. If you can, put the car in park.
- For a few seconds, hold down the VSC button.
- The indicator lights for TRAC OFF and VSC OFF will turn on. Now both systems are off.
- Once more, press the VSC button. As soon as both lights go out, the systems are back in operation.
If the VSC OFF light is still on, there can be a glitch in your car’s computer or a problem with the VSC system. Bring your car to a Toyota service location near you so a qualified technician can check the codes and identify the problem. Although it is safe to drive your Toyota even with the VSC OFF light on, we advise caution, especially in bad weather.

Is there a locking differential on the Tundra TRD?
A locking differential and Crawl Control are now official additions to Tundra’s off-road toolkit. The all-new 2022 Toyota Tundra features the TRD Off-Road package in addition to the extreme TRD Pro variant.
Open vs Limited-Slip Differentials
Differentials vary from one another. Differentials come in at least four different varieties, each of which is appropriate for a variety of driving circumstances. The open differential found in most cars allows a wheel to keep spinning even after it slips. In essence, the inner wheel revolves more slowly than the outer wheel. If there is no rain, gravel, ice, or snow and the road conditions are normal, this is acceptable. The biggest winners from open differentials will be those who reside in tropical areas.
For open roads, the limited-slip differential is also appropriate. It is like an open differential since engine torque gets delivered to each individual wheel. However, the slipping tire is where there is a significant difference. If you were using an open differential, the tire would typically slip as you made sharp turns and accelerated quickly. However, a limited-slip differential lowers the amount of torque sent to the sliding tire. Once this has occurred, it is simpler to make quick, hard turns. In this case, an open differential would struggle.
Due to their frequent use in races, high-performance vehicles like race cars frequently use limited-slip differentials. On regular roads, a police car may feature a limited-slip differential to make it easier to chase suspects around turns. However, a limited-slip differential won’t be any better than an open differential on roads with snow and ice.
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. Second, you may experience severe vibrations due to a fluid leak in your differentials. They will start to malfunction very soon if that is the case.
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.
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.
Does anyone know what model, OEM brand, or component package the 2017 Transit Wagon axle belongs to? Any specifics on the LSD components, please? I suppose I should at the very least make an effort to learn more about the systems that our Transit is powered by so that we can take good care of it.
Driving while wearing a slip light is it safe?
Is it safe to drive if the slip light is on? The presence of the light denotes active traction control. Driving without traction control puts your car at risk of slipping or spinning out on the road.
What is the cost of repairing a slip indicator light?
You must locate the problem in order to turn off the slide light. If the indicator flashes on and then disappears, you’re probably just on a slick road and the system is functioning normally. When you regain traction, if it still doesn’t switch off, there might be a problem that needs to be fixed.
A defective wheel sensor will need to be changed if the slip light is illuminated as a result of it. The cost to replace a wheel sensor ranges from $200 to $250 on average. In some circumstances, you could repair the sensor and reinstall it to save some money.
If the sensor isn’t the problem, you might give the wiring a second inspection to make sure the connections and integrity are OK. It is preferable to replace the wiring if it appears to be worn.
You will have to pay a bit extra money if the ABS control unit needs to be replaced. Costs for replacing an ABS control module range from $320 to $1,000 on average. The price increase isn’t due to labor costs, though. The component itself may even be pricey.
Checking the trouble codes with a compatible OBD2 scanner is the quickest approach to find traction control problems.
