A light that is on is not a great sign. It is easy to believe that this is simply a problem related to sensors . However, it is important to pay attention to it. How does ABS work? Why is the indicator light on? How to do? We will answer these questions, so you can get behind the wheel of this Renault Grand Scenic 3 with confidence.
What is ABS on a Renault Grand Scenic 3
ABS stands for Anti Blocking System . It is a device which offers the possibility of improving the braking system, in particular for intensive braking. Before the invention of ABS, the brake pedal was simply connected to the pads. As soon as you step on the pedal, the pads stick to the discs. The disadvantage with this system is that there may be a risk of slippage. Thanks to sensors, ABS calculated the braking system. Instead of staying pressed on the discs, the pressure will decrease and then increase various times per second, thus preventing a blocking complete wheels of your Renault Grand Scenic 3. No skidding, and braking becomes more efficient.
Renault Grand Scenic 3: why the ABS warning light is on
If the ABS warning light is on, your Renault Grand Scenic 3 is sure to have a problem. As with all the other witnesses, it is relatively common for this to relate simply to an electrical connection problem. That said, it's better to be sure.
False contact
Go up the ABS sensor lines of your Renault Grand Scenic 3 and take the electrical intensity with a multimeter . Supposing that one of them does not have the same value as the others, it means that there is an electrical fault. Follow the line, if you find a connection fault it is necessary to resolve it. If ever a cable is in bad condition, it is necessary to replace it.
A sensor problem
This naturally remains a relatively frequent problem on a Renault Grand Scenic 3. The detector may be sending the wrong message. In this situation, simply replace the problematic sonar. You can control the sensors using a oscilloscope .
A problem with the hydraulic block
The ABS of your Renault Grand Scenic 3 operates using a device hydraulic , which will manage the force of the brake pads. When this device is deficient, replacement of the ABS unit is generally necessary. In the event that this remains a block problem, you can often feel it while braking.
Conclusion
An ABS warning light that remains on may be due to very different reasons. Either a sonar problem, a false contact. If the ABS unit is defective, it is probably necessary to replace it. And this intervention happens to be relatively expensive, on a Renault Grand Scenic 3 or on any car model. It is important not to neglect an ABS warning light, for understandable safety reasons. Do not hesitate to leave a comment if this specific ABS indicator light file has helped you. Good walk!
