What is ABS on a Toyota Land Cruiser Serie 70
ABS means Anti Blocking System . It is a system which will make it possible to improve the braking system, in particular for intensive braking. Before the development of ABS, the brake pedal was simply tied to the pads. When you depressed the pedal, the pads stuck to the discs. The disadvantage with this system is that there is a chance of slippage. Thanks to sensors, the ABS assesses braking. Instead of staying pressed on the discs, the pressure will vary a number of times in a very short time, thus preventing a blocking total wheels of your Toyota Land Cruiser Serie 70. No skidding, and braking is much more efficient.
Toyota Land Cruiser Serie 70: why the ABS warning light is on

False contact
Reassemble the lines of the ABS sensors of the Toyota Land Cruiser Serie 70 and read the electrical voltage with the help of a multimeter . If one of them does not have the same value as the other three, there is an electrical problem. Reassemble the cables, if you discover a connection fault you will have to fix it. When a wire is in bad condition, you will need to replace it.
A sensor problem
This is obviously a rather recurring problem on a Toyota Land Cruiser Serie 70. It happens that the sensor sends an incorrect message. Then, it will suffice to replace the sensor concerned. You can check the sensors using a oscilloscope .
A problem with the hydraulic block
The ABS of the Toyota Land Cruiser Serie 70 works using a device hydraulic , which will make it possible to manage the force of the brake pads. When this device fails, replacement of the ABS unit is usually mandatory. If this remains a problem with the block, you can often feel it when braking.
Conclusion
An ABS warning light that comes on can be caused by quite different causes. Either a sensor problem, a false contact. If ever the ABS unit is faulty, you will probably have to replace it. And this intervention is rather expensive, on a Toyota Land Cruiser Serie 70 or on any other type of car. It is essential not to neglect an ABS indicator, for understandable safety reasons.
