The slip indicator is a symbol that signals your vehicle’s traction control system is actively working to prevent wheel slip and help you regain control. It is one of the many warning lights that pop up on your dashboard to communicate with you as the driver regarding the status of your car. It is a great example of how modern technology can create a more real-time communication channel between you and your car’s complex algorithms.
Your Nissan is equipped with a set of sensors that are located on each of your wheels. These are responsible for relaying data to the Powertrain Control Module (PCM), which can then look at if the wheel is losing traction. Once it determines this is occurring, it will decrease the amount of power sent to that particular wheel to ensure you do not lose control.
When the slip light stays on, however, there may be a problem with the sensors or their connectivity with the PCM. They can get dirty or clogged with debris, which could result in the failure of the system to function properly. This is why it is important to find an ASE Certified mechanic to help you troubleshoot the issue and figure out what is causing your Nissan’s slip light to remain on.
The best thing you can do if your slip indicator light is on is to check your tire pressure. Low pressure in one or more tires will cause this to occur and should be corrected as soon as possible. You should also check your brake fluid level and make sure it is at a safe level.
