RAM 2500 ABS Light Is On? Causes & How to Turn It Off

RAM prioritizes safety and uses features like anti-lock braking systems (ABS) to keep 2500 drivers and passengers safe during an emergency or hard braking. It prevents the vehicle from skidding and helps drivers to maintain control.

Why does the ABS light on RAM 2500 come on? And how does it impact driving safety? Here are the causes and ways to resolve the ABS light on RAM 2500.

Faulty Wheel Speed Sensor

Every wheel has a sensor to monitor its speed and relay the information to the ABS control module. The control unit uses the sensor data to identify wheels prone to locking up when braking.

A faulty sensor cannot detect wheel lock-up when braking. The defective sensor prompts the RAM 2500 ABS control module to turn on the warning light to inform the driver of the underlying issue.

How To Inspect ABS Sensor on RAM 2500

2500 owners can identify ABS sensor defects using an OBD2 scanner. You can also visually inspect the sensor, although it only enables it to check physical damages and debris that could impede sensor performance. The OBD2 scanner accurately identifies and specifies RAM 2500 ABS sensor defects.

Check the Speed Sensor Wire, Or Connector

The speed sensor could be working perfectly. However, damage to the communication wire or loose connections may interrupt signal transmission between the RAM 2500 wheel and the ABS module. Speed sensor wire damages are visible and could occur due to corrosion or wear due to impact with hard materials.

Low Level of Brake Fluid

RAM 2500 braking system relies on hydraulic fluid. The hydraulic fluid reservoir has a sensor to monitor brake fluid levels. A low brake fluid level causes the ABS light to come on. Topping up the brake fluid to appropriate levels turns off the ABS light.

Reasons For Brake Fluid Running Low

RAM 2500 brake fluid levels drop when:

  • Brake pads or rotors wear.
  • Leakage exists along the brake system.

You should identify the cause of the low brake fluid before topping it up for maximum driving safety.

Flawed ABS Pump Or Control Module

RAM 2500 ABS pumps modulate brake fluid pressure in response to different driving conditions. The ABS control module processes the information from the wheel sensors and adjusts the ABS pump operations accordingly.

A faulty ABS pump cripples the operations of the entire anti-lock brake system. A warning light will appear on the RAM 2500’s dashboard to alert drivers of an existing defect. Similarly, a defective ABS control module cannot effectively manage sensor data and control the operations of the pump, causing the ABS light to come on.

Low Tire Pressure

Low tire pressure is one of the indirect causes of the ABS warning lights. Underinflated tires spin faster than other wheels, causing the speed sensor to send wrong information to the RAM 2500 ABS control module. The control module generates an error code that illuminates the warning light on the dash.

Check tire pressure regularly and maintain the correct tire pressure for proper operation of the braking systems.

TPMS Warning Light

Moder RAM 2500 models have Tire Pressure Monitoring Systems (TPMS) to alert drivers when tire pressure drops below recommended levels. ABS problems due to low tire pressure are accompanied by TPMS warning light

Blown Fuse Or Bad Relay

Fuses and relays are vital for protecting RAM 2500 ABS systems from excess electrical current. The braking system may stop working if these components are faulty. Once the ABS stops working, an error code prompts the control unit to display the warning light.

Confirm the RAM 2500 fuse or relay rating before replacement. Check the electrical system if the relay or fuse blows up again.

What Are ABS And Traction Control In A RAM 2500?

ABS and Traction Control are critical safety features in most RAM 2500 vehicles. These systems work together to maximize driving comfort and safety. The anti-lock braking system prevents wheel lock-up when a driver brakes quickly. ABS helps prevent skidding and maintains steering control. You can enjoy predictable braking responsiveness on dry and wet roads.

RAM 2500 Traction Control helps reduce engine power supplied to wheels whenever the system detects traction losses. It lowers engine power or applies braking forces to individual wheels based on the traction levels. Traction Control is beneficial when driving on slippery roads and reduces the probability of skidding.

ABS and Traction Control systems enhance the stability and safety of most RAM 2500 models. You can activate or deactivate them depending on the driving conditions.

What Happens to RAM 2500 When The ABS Light Is On?

RAM 2500 owners should pay attention to the ABS warning lights coming on. They indicate an existing issue with the braking system or low tire pressure. The RAM 2500 does not lose its regular brakes when the ABS lights come on. However, you should not disregard the warning alert. The appearance of ABS warning lights on the dashboard means the safety levels of the RAM 2500 are lowered, with an increased possibility of skidding when hard-braking.

Your RAM 2500 ABS lights may come on if:

  • Brake fluid is low
  • The speed sensor is damaged
  • ABS pumps or Control Module are faulty
  • The ABS relay or fuse is blown
  • Tires have low pressure

How To Turn Off ABS Light On RAM 2500

The ABS warning light disappears once the underlying issue is fixed. Sometimes the warning light remains on after solving the root cause.

However, it disappears after driving for a few miles. Some ways to solve RAM 2500 ABS warning light issues include:

  • Topping up brake fluid
  • Maintaining correct tire pressure
  • Replacing damaged wheel sensors and connections
  • Repairing or replacing the ABS pump and control module
  • Replacing blown fuses and relays

Using an OBD II scanner to identify and clear error codes, you can turn off warning lights.

Is It Safe To Drive RAM 2500 With ABS Light On?

The ABS warning light does not affect regular brakes. Braking remains predictable in dry conditions. However, RAM 2500 drivers may face difficulty braking and steering in wet conditions. One is more likely to lose steering control. Check the braking system when the ABS and Brake warning lights come on.

How To Reset The RAM 2500 ABS Light

Fix The Issue

Identify the cause of the warning light and find a way to resolve all underlying issues. If the error code is due to faulty speed sensors, find the correct replacement and fix it. The RAM 2500 ABS light goes off after resolving underlying problems.

OBDII Scanner Method

The OBDII scanner is the most accurate way to clear ABS-related error codes. The scanner resets RAM 2500 warning lights if they do not go off after fixing the root causes of the alert.

Disconnect The RAM 2500 Battery

Disconnect the battery and drain the electricity from the system. Start with the negative terminal when disconnecting the battery. After a few minutes (10-15 minutes), reconnect the battery. Connect the positive cable first. This should clear the warning light.

How Much Does It Cost To Fix ABS On RAM 2500?

The cost of fixing ABS on the RAM 2500 depends on the faulty component triggering the alert. The price ranges from $100 for speed sensor replacement to over $1200 to replace defective ABS pumps.

Final Remarks

ABS warning lights on RAM 2500 indicate an underlying issue with the braking system. It is a safety concern requiring the driver’s attention. Ensure you resolve all issues triggering the ABS warning light alerts to enjoy safe driving in all conditions.
