Nissan malfunction indicator Nissan malfunction indicator light
Check your car’s dashboard Nissan malfunction indicator lighting as it is essential to identify your car’s potential problem, safety issues, or immediate failure points.
The following guide will help you understand which car warning Nissan malfunction indicator light symbols and indicators can be found on your dashboard for most makes and models of cars, trucks, buses, and motorbikes.
You’ll learn whether it is a critical warning that requires immediate attention, or whether you have time to visit a local mechanic.
1. Brake Warning indicator light
Indicator Nissan malfunction indicator light turns on when the handbrake is on. If it lit continuously, it means that hydraulic pressure has been lost in one side of the brake system or that the fluid level in the master cylinder is dangerously low (due to a leak somewhere in the brake system)
What the brake pad wear indicator warning Nissan malfunction indicator light means
Quite simply, when this Nissan malfunction indicator light is on, the sensor in the brakes has determined that the brake pads are too thin. There are 2 main ways that auto manufacturers achieve this diagnosis.
The first is by using a small sensor embedded into the brake pad material itself. As the pad wears out, the sensor will eventually come into contact with the rotor which completes a circuit and turns this indicator Nissan malfunction indicator light on.
The second method is a position sensor that measures how much the pads have to move before the brakes are applied.
This brake system warning Nissan malfunction indicator light also requires urgent attention.
It may be that you’ve left the handbrake engaged Nissan malfunction indicator lightly while pulling away, so ensure it’s fully released.
If this doesn’t solve the problem, or the warning Nissan malfunction indicator light appears as you’re driving along, pull over safely and call for roadside assistance or arrange for the car to be taken to a garage. It may be that the brake fluid level is too low and simply needs topping up, or that a brake pad wear sensor is faulty.
However, it could also be a more serious issue with the braking system. While you can’t take the risk either way, if the pedal feels spongy when you press it or sinks all the way to the floor, then it’s easy to tell a significant issue has occurred and the car should definitely not be driven any further.
What it means: It’s likely that you left your handbrake on. But if the Nissan malfunction indicator light is still lit when you are driving, it could mean your car is low on brake fluid or something more severe.
What to do: If the red brake Nissan malfunction indicator light blinks or comes on and off intermittently, and there is no change in the feel of the brake pedal, then have the vehicle properly diagnosed by a qualified repair shop as soon as possible.
But if the Nissan malfunction indicator light is permanently lit, the vehicle should be pulled to the side of the road and towed to a qualified repair shop.
What the brake warning Nissan malfunction indicator light means
As mentioned before, the brake Nissan malfunction indicator light may be on because the parking brake is engaged. If disengaging the parking brake does turn off the Nissan malfunction indicator light, then the computer has detected an issue with the braking system. Most commonly, this may be due to an issue with the brake fluid.
The brake fluid reservoir has a fluid level sensor built in to make sure there is sufficient fluid in the system at all times. As your brake pads wear out, more fluid is pushed into the lines which lower the overall level in the system. If the pads get too thin, the fluid level will go down too much and trip the sensor. A leak in the system will also cause the sensor to trip and the Nissan malfunction indicator light will illuminate to warn you of the low levels.
What to do when the brake warning Nissan malfunction indicator light is on
If the Nissan malfunction indicator light is on, first check to make sure that the parking brake is fully disengaged and then check the fluid level inside the reservoir. If neither of these seems to have any issue, then you should have your parking brake cable inspected and adjusted, if necessary. A cable that is out of adjustment may not completely disengage the parking brakes even if the handle is released. If the vehicle is low on fluid, have the pads and brake lines inspected for leaks or worn out parts.
Is it safe to drive with the brake warning Nissan malfunction indicator light on?
Depending on how severe the issue is, the car may or may not be safe to drive. If the Nissan malfunction indicator light comes on, you should pull over safely out of traffic to check the parking brake and fluid level. With a severe fluid leak, you will not be able to use the brake pedal to stop the car quickly, and you will have to use the parking brake to slow the vehicle down. This is risky as the parking brake is not nearly as effective at stopping the vehicle as to the brake pedal.
