We tried disconnecting the battery, but that had no effect. Nothing seems to be working no matter how I crank the 4WD knob or press the center diff lock button. I suppose my brother will need to transport it tomorrow.
Did he hit the center diff lock before shifting into 4LO, since that occurred to me as well? If so, while in neutral, turn the knob back to 4LO, then push the center diff lock to turn it off, and finally switch back to 4Hi. The correct sequence is 4H, then 4LO when in neutral, followed by Center Diff Lock, which is turned off while switching out, before moving on to 4LO and 4H. You will have the issue it appears your brother is experiencing if this is done in any other way. If not, good luck finding a solution.

How do I deactivate Toyota 4LO?
Find the 4WD knob on a Toyota Sequoia and turn it to the 4L position to disable four-wheel drive. When you deactivate the four-wheel drive in your car, the 4LO and VSC OFF lights should illuminate. You may now reduce your gas use and drive more comfortably!
How does 4LO work in 4runner?
All generations of 4runners shared a common type of part-time 4WD. It was an antiquated kind of 4 wheel drive on the first and second generation cars, with either manual locking hubs or a technology known as Auto Differential Disconnect.
The front driveline continued to spin and wear even while the front differential is disengaged because of this mechanism, which essentially detached the axles from the front differential but enabled them to spin freely with the wheels.
When to use each 4WD setting in a 1st and 2nd gen 4runner
Except while driving in slick weather, you should always be in 2WD. Change to 4hi if you need extra traction. Due to the fact that the front and back are equally locked, 4HI should not be used on dry ground. This could damage the driveline by causing binding in the driveline.
A 4lo setting is available on all 4WD 4Runners. This modifies the gearing to allow the car to go at a sluggish rate. Only use 4lo to climb or descend steep hills, assault sizable rocks, or extricate a stalled vehicle.
How to engage 4WD in a 1st or 2nd gen 4runner
Get outside, lock your hubs, and then switch to the 4hi position. (Shift to the 4hi setting if your 4runner doesn’t have manual hubs.)
Put the transmission in neutral, then shift to the 4lo position while coming to a stop.
My 4LO is beeping; why?
You are not in four low. When traveling at less than 65 mph, shift into high, but let off on the gas to make the move simple. Stop, engage the clutch (manual), or switch to neutral (automatic), then downshift. Any beeping indicates a mistake was made.
Why is the flashing in my 4WD Low light?
Most of the time, a flashing 4WD light simply indicates that the system is functioning as intended and should not be cause for concern. When four-wheel drive is only engaged in vehicles on demandthat is, when traction conditions call for itthis light turns on to let you know that it has been engaged. It resembles the traction control or stability control lights on your dash in certain ways, which also illuminate when the corresponding systems are engaged.
It’s crucial to maintain composure when you see the 4WD icon lit up on your dash. Follow these troubleshooting methods to determine which scenario your car might encounter. It’s usually a good idea to get in touch with your mechanic for advice if you experience major issues.

On the highway, is it safe to drive in auto 4WD?
On dry pavement, using 4×4 puts a lot of stress on the driveline’s components and wears down the tires. Each wheel must turn at a slightly different speed as the truck corners or makes any turns at all. The front and rear axles are locked together whether four high or four low is chosen.
How quickly can a 4 Lo 4Runner travel?
Some people might find it strange to ask how fast you can drive in 44 low, but it’s actually a very pertinent topic because off-road environments present a variety of scenarios that call for diverse responses. This post will go over how using 44 low affects your speed by reducing gear ratios. We’ll also examine when to use 44 low and how it handles different off-road scenarios.
Since 44 low typically has little grip, rough, steep, and irregular surfaces that call for low-speed control, driving speeds should never exceed 10 mph. On challenging off-road tracks, driving in low range is only advised up to 10 mph.
Having stated that, we also need to comprehend when to drive in 44 high or 4H and when it is appropriate to engage 44 low. The following section of this post goes through when to drive in 44 hi, how quickly we should go in 44 low, and what happens to the 44’s driving characteristics when we drive in low range.
What does 4Runner’s H4 and L4 mean?
I’m pleased to assist you and congratulations on your new motorcycle! Use the shift lever to select four-wheel-drive high (H4) or four-wheel-drive low (H4) to engage four-wheel drive on a Toyota 4Runner (L4). More information is provided below.
- Additionally, you can switch your vehicle to high-performance two-wheel drive (H2).
- To switch to or from L4, your vehicle must be stopped. Put the car in neutral and apply the brakes. Next, change into L4 with the gear shift lever (or H4).
- To establish your new gear, you can either shift into drive or reverse.
- While driving, you can switch between H2 and H4 as long as your speed is under 50 mph.

Why is my Toyota Tundra’s 4Lo light blinking?
Your brake stroke sensor is malfunctioning. I’m having the same problem. I simply haven’t had the time to replace it. Usually, I have to put it in park, shift to 4 lo, then back to 2 wd.
My Toyota 4Runner is beeping; why?
The most frequent reasons a Toyota 4Runner will beep include the dash camera, anti-theft alarm, sunroof being open, malfunctioning seatbelt sensors, weak electrical connections, low keyfob battery, GPS alerts, low tire pressure, poor door latches, or 4 Low not being correctly engaged.
There are many different reasons why something can beep; we’ve listed the most frequent ones here.
Why does Tacoma’s 4lo beep?
It might not be engaging if your Toyota Tacoma 4 Low is beeping. To change to 4 Low, you must fully brake, put the truck in Neutral, and then do so. You can put it in drive and start driving because it should engage without beeping.
To provide the power required to safely descend and ascend steep gradients with loose rock-strewn surfaces or hills involving mud, sand, or snow, low range four-wheel-drive, also known as 4 Low, requires alternative gearing.
Shifting From 4H to 4L (Automatic)
With an automatic transmission, the car MUST come to a complete stop before shifting from 4H to 4L.
- Put an end to the car
- Put the brakes on.
- Put the transmission in neutral and maintain your foot on the brake pedal.
- Adjust the control to 4l.
It should be noted that leaving Neutral before the 4L light has solidified can harm the transfer scenario.
Reverse the process to change back into 4H, then watch for the indication light to disappear.
Shifting From 4H to 4L (Manual)
- If it’s not possible to stop, drop the speed to only 2 mph.
- From 4H to 4L, push and adjust the control knob.
- Hold the clutch pedal depressed.
- Release the clutch pedal only after the indicator has been on when engaging and off while disengaging.
Note: It’s best to always read your owner’s manual to make sure these instructions apply to your Toyota model.
Driven with the service 4WD light on, is it okay?
Any alarm that flashes on your car’s dashboard can be stressful, especially if you don’t know how serious it can be. When the 4WD light comes on, it is alerting you to a problem with the 4WD system that has to be fixed right away.
An incomplete gear shift is another factor that could cause this light to come on. This is perplexing, harmful to the engine, and might cause your 4WD service light to glow nonstop. Make sure to shift entirely before starting your drive to prevent this. Get to a qualified mechanic as soon as you can if you think you have put the car in gear correctly but the light is still on since it might be a transmission problem.
When the driver switches from 2WD to 4WD while the car is moving, this has an effect on the service message. This can seriously harm your 4WD system and push it into a frenzy. It’s crucial to entirely change gears while the automobile is still moving to avoid harm. This will facilitate a less abrupt shift and protect your engine from harm.
Constantly flashing the 4WD option may occasionally be a sign of a system issue. Any driver can find that obnoxious and inconvenient notification. Internal computers that are programmed into cars can read every movement you make with them. A car computer, like a traditional computer, may experience programming errors that result in an alarm. Consider the timing of your flashes to ascertain whether the issue is mechanical or computer-related. Many times, computer-related problems in cars might start other underlying problems. It is crucial to treat these problems carefully as a result.
