The following article discusses full details about various culprits that may be making your Ford Ranger ABS light come on and how you can reset the light.

Ford Ranger ABS Light Coming On: Common Causes

Ford Ranger ABS Light Coming On

Below are the common causes for your Ford Ranger ABS (Anti-lock Braking System) light to come on:

Damaged ABS Pump or control module

The task of the ABS pump in your Ford Ranger is to control the brake fluid pressure according to the various driving conditions.

This control module collects information from the wheel sensors, adjusting the operations of the Ranger’s ABS to pump accordingly.

A damaged ABS pump cripples the whole operation of the antilock brake system. The light illuminates the dashboard, alerting the drivers that there is a defect existing.

The same applies to a faulty control module, which will be unable to control the pump operations. This triggers the light to come on as well.

Low pressure on the tire

A Ford Ranger having low pressure in one or more of its tires can also cause the ABS warning light to come on.

When the wheel is not inflated, the diameter of the wheel decreases, thus causing the tire to rotate more quickly than the other tires.

Bad wheel speed sensor

Your Ford Ranger ABS has a sensor at each wheel that monitors the actual speed of the wheel and gives the information back to the ABS control unit.

A damaged wheel speed sensor is a major cause of ABS light coming on in a Ford Ranger as it’s at high risk of damage due to its closeness to the wheels.

If the sensor gives inconsistent data about speed, an ABS light turns on in the cluster instrument. It is impossible to know exactly the damaged ABS sensor in a Ford Ranger by just inspecting it physically.

Low brake fluid level

A very low amount of brake fluid can cause your Ranger ABS light to illuminate.

The main causes of low brake fluid include system leakages, damaged brake lines, worn rotors, and brake pads.

A blown fuse or faulty relay

A blown fuse causes the braking system to stop operating, and after they have stopped, the light illuminates.

Check the ABS pump/control module.

It is good to connect a diagnostic tool and read the codes (the ABS pump code is C1095, and the control module is U0121). You will be able to know where the exact damage is and replace it with a new and clean one that looks similar to the previous one. 

Check the amount of pressure on the tire.

For you to have good operations of braking systems, it’s good to keep checking the amount of pressure present on tires. Maintain the correct pressure (between 30 and 38 psi) by regularly keeping your tires inflated.

Inspect the speed wheel sensor.

The best way to examine this sensor is by connecting an OBDII scanner to your Ford Ranger and then scanning the error code (code P0500). This error code enables you to know exactly which sensor is damaged.

It is important to look at the level of brake fluid to ensure it sits close to the high mark of the reservoir. You should inspect rotors and brake pad conditions.

Also, inspect if there could be any sign of fluid leakage on the wheels and beneath your Ranger and have it fixed before topping up more brake fluid.

Inspect the fuses

You should also check the condition of the fuse for the ABS system. This is usually a 10A fuse located in the passenger compartment box.

If you discover it has blown (i.e., it appears burnt or broken) or if it fails the continuity test, you can replace it with another one according to its rating amp.
