why is my Ram 1500 DT (2019-Present) traction control light on

Solution

1. Preparation

• Gather necessary tools and materials.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

• Locate the wheel speed sensors on each wheel hub.
• Clean any dirt or debris around the sensors using a soft cloth.
• Disconnect the electrical connector from each sensor and inspect for corrosion or damage.
• Reconnect the sensors and ensure they are securely fastened.

3. Check ABS Module

• Locate the ABS module typically found near the brake master cylinder.
• Inspect the wiring harness for any signs of damage or loose connections.
• If an error code indicates a fault, replace the ABS module as per manufacturer specifications.

4. Brake Fluid Inspection

• Check the brake fluid reservoir for proper fluid level.
• If low, top off with the manufacturer-recommended brake fluid type (usually DOT 3 or DOT 4).
• If the fluid is contaminated, perform a brake fluid flush and replace with fresh fluid.

5. Traction Control Switch Check

• Locate the traction control switch on the dashboard.
• Test the switch for functionality; it should toggle the traction control system on and off.
• If the switch is faulty, replace it with a new one.

6. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the vehicle and monitor the dashboard for the traction control light.
• Test drive the vehicle to ensure the system operates correctly.
