When any of your tires have low tire pressure, the ECU ends up sensing an abnormal speed. It may send off inaccurate or flawed information to the ABS or Traction Control, which inadvertently activates their warning signals. 6. A Defective Steering Angle Sensor.

What is traction control?

On the other hand, Traction Control is a system that monitors your vehicle’s stability and steering performance. It keeps track of historical data on how your car grips the road and draws across its surface. If it detects anything outside of the usual patterns based on these historical data, it proactively finds the potential error and fixes it. It spurred the requirement for ABS and is an essential part of vehicle safety.

What is a limp mode?

The limp mode (or limp home mode) is a self-preservation security feature in cars that activates when it detects abnormal readings or a malfunctioning electrical component or mechanical operation.

Make sure to address immediately (if you find any) as it could be quite dangerous if left unattended.

What is the difference between ABS and brake light?

The ABS light differs from the BRAKE light as it is usually controlled by a computer module. When this light is on, there are often trouble codes stored to help the owner or a technician diagnose the source of the fault in the anti-lock braking system.

Why does my car have a brake light?

The “BRAKE” light has always meant one simple thing: There is a fault with the braking system. Most commonly, this light is triggered by low brake fluid or an engaged parking brake. However on some vehicles, it can simply indicate a problem elsewhere in the system and can be illuminated immediately if there is an ABS fault.

How do brake lights work?

The BRAKE light on most vehicles is activated by a simple circuit involving only one or two components.
