Problem Statement

Learn how to troubleshoot traction control problems in Ford Explorer (2011-2019). Step-by-step guide with diagnostic steps and repair instructions.

Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components
•Allow the vehicle to cool before inspecting brake components

Symptoms

•Traction control warning light illuminated on the dashboard
•Vehicle feels unstable during acceleration, especially on slippery surfaces
•Loss of power to the wheels when attempting to accelerate
•ABS (Anti-lock Braking System) light may also be illuminated
•Unusual noises from the wheels during TCS engagement
•System occasionally activates during normal driving conditions

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any stored diagnostic trouble codes (DTCs)
2
Inspect wheel speed sensors for damage or disconnection, as these are crucial for TCS operation
3
Check the brake fluid level and condition, as low fluid can affect ABS and TCS functionality
4
Examine the ABS control module and wiring for signs of wear or corrosion
5
Perform a visual inspection of the tires to ensure they are properly inflated and have adequate tread depth
6
Test the TCS switch to ensure it is functioning correctly and is not stuck in the off position

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•OBD-II scanner
•Socket set
•Multimeter
•Tire pressure gauge

Parts Required

•Wheel speed sensors (if faulty)
•TCS switch (if defective)
•Brake fluid (if low)

Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, tire pressure gauge.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor connector by pressing the release tab and gently pulling it apart.
Inspect the wiring harness for damage or corrosion.
Use a multimeter to measure the resistance of the sensor; it should typically be between 800-1200 ohms. Replace if out of range.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Remove the cap and check the fluid level. If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect for leaks around the brake lines and wheel cylinders.

4. Inspect ABS Control Module

Locate the ABS control module, usually found near the brake booster.
Check for loose or corroded connections and ensure all connectors are secure.
If necessary, clean the terminals with an electrical contact cleaner.

5. Verify Tire Condition

Use a tire pressure gauge to check the pressure in all tires; refer to the vehicle's owner manual for correct specifications.
Inspect the tread depth using the penny test or a tread depth gauge; replace tires if tread is below 2/32 inches.

6. Test TCS Switch

Locate the TCS switch on the dashboard.
Remove the switch from its housing and use a multimeter to test for continuity when the switch is pressed.
Replace the switch if it does not show continuity.
