An indicator light that turns on is not necessarily an excellent sign. We can think that it is just a concern from sensors . However, it is crucial to pay attention to it. What is the role of ABS? Why does the indicator light go off? What to do? We will answer all these questions, so you can get behind the wheel of your Toyota Hi Ace with confidence.warning-abs-Toyota-Hi-Ace

What is ABS on a Toyota Hi Ace

ABS stands for Anti Blocking System . It is a mechanism that improves braking, among other things for sustained braking. Before the invention of ABS, the brake pedal was simply linked to the pads. As soon as you pressed, the pads stick to the discs. The downside with this mechanism is that there may be a risk of slippage. Using sensors, ABS assesses braking. Instead of maintaining the discs, the pressure will decrease and then increase several times in a very short time, which will prevent a blocking complete wheels of the Toyota Hi Ace. No skating, and braking is much more efficient.

Toyota Hi Ace: why the ABS warning light is on

If the ABS warning light remains on, there is no doubt that your Toyota Hi Ace has a problem. As with all other LEDs, it is quite common for it to be just a concern for contact. Having said that, it's better to be assured.

False contact

Reassemble the ABS sonar cables of your Toyota Hi Ace and take the electric voltage using a multimeter . In the event that one of them does not hold the same value as the other three, it means that there is an electrical fault. Follow the line, if you discover a bad connection you will have to troubleshoot it. When a cable is damaged, it will have to be changed.

A sensor problem

This is of course a rather common concern on a Toyota Hi Ace. The sensor may be sending the wrong message. In this specific case, it will be enough to change the problematic sensor. You can control the sensors using a oscilloscope .

A problem with the hydraulic block

The ABS of your Toyota Hi Ace works using a system hydraulic , which will manage the intensity of the brake pads. In the event that this system fails, changing the ABS unit is generally necessary. If this remains a concern of the block, it is generally felt by braking.

Conclusion

An ABS warning light that stays on can come from a variety of causes. Either a sensor problem, a false contact. If the ABS unit is damaged, it will probably have to be replaced. And this intervention is relatively expensive, on a Toyota Hi Ace or on each vehicle model. It is essential not to abandon an ABS warning light, for understandable safety reasons.
