How to Tell if a Relay is Bad in a Car, Truck, or SUV

What Does a Relay Do?

Before we discuss how to tell if a relay is bad in a car, let’s cover the purpose of a relay. Relay switches are used to reduce the amount of electric current that’s flowing through a particular circuit inside your car. It takes a huge amount of amperage to operate some of the vehicle’s functions. As such, allowing all of it to go through a switch without a relay could cause the switch to burn a lot faster. 

Relays are used with headlights, the car’s horn, automatic windows, air conditioning, and other functions that require a circuit. They are designed to take on the excessive amperage but can also burn out after some time.

Learn to Diagnose and Fix Low-Speed ABS Activation in Your Chevy Truck

One of the most common Chevy truck ABS brake problems is low-speed ABS activation. To find out why your Chevy truck has low-speed ABS activation, it’s best to first understand how the system works. The anti-lock braking system (ABS) is a safety feature that prevents your vehicle’s wheels from locking up when you suddenly press hard on the brake pedal. Locking up refers to when the wheels stop rotating, leaving the vehicle to slide forward due to the momentum. 

In such a situation, the driver would not be able to effectively steer the car away from any objects that may be in front of him. The ABS system uses sensors to monitor the wheel’s rotational speed and a hydraulic unit to “pump the brakes”. This helps it know when to apply the brakes. 

It repeatedly applies and releases the brake to prevent the wheel from locking up. Depending on the car you own, it could be connected to all four wheels or just the front wheel.
