Important safety information - read before proceeding

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

Symptoms

•Traction control light illuminated on the dashboard
•Reduced engine power during acceleration
•Unusual wheel spin or loss of traction in slippery conditions
•Vehicle stability control system may also engage unexpectedly
•Possible accompanying check engine light or other dashboard warning lights

Diagnostic Steps

1
Scan the vehicle's onboard computer using an OBD-II scanner to retrieve error codes.
2
Inspect the wheel speed sensors for damage, dirt, or disconnection.
3
Check the ABS (Anti-lock Braking System) module for any fault codes or malfunction indications.
4
Verify the condition of the brake fluid and level in the master cylinder.
5
Test the traction control switch for proper operation.
6
Inspect the wiring harness connected to the traction control system for any signs of wear or damage.

Solution

Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel assembly.
Remove any dirt or debris from the sensors and their connectors.
Use a multimeter to check for proper sensor resistance (typically around 1,000 ohms). Replace sensors if readings are outside manufacturer specifications.

3. Check ABS Module

Reconnect the battery and scan for codes again.
If there are ABS-related codes, follow the manufacturer's service manual to access the ABS module.
Clear any fault codes and test the system to see if the light reappears.

4. Brake Fluid Check

Inspect the brake fluid reservoir for proper fluid level.
If low, top off with the recommended brake fluid type (usually DOT 4).
If the fluid is contaminated, perform a brake fluid change.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Remove the switch and test it with a multimeter for continuity.
Replace the switch if it does not function as intended.
