Tools Required

Multimeter
Basic hand tools (screwdrivers, socket set)

Vehicle repair manual (for reference)

Repair Instructions

Based on the diagnostics, here are the repair steps you may need to take:

If Traction Control is Off
- If the traction control was turned off manually, simply toggle the switch to re-enable the system. This should turn off the warning light.
If Diagnostic Trouble Codes are Present
- Identify and Address Codes:
  - For wheel speed sensor codes (e.g., C0035), inspect the sensor and wiring; clean or replace as necessary.
  - If the ABS module codes are present, inspect the ABS control module and wiring for faults.
- Clear the codes using the OBD-II scanner and check if the warning light reappears during a test drive.
Inspect Wheel Speed Sensors
- Remove the wheel and tire to access the wheel speed sensors.
- Use a multimeter to test the sensor's resistance. Compare with specifications in the vehicle manual.
- Clean the sensor and its mount if dirt or debris is present. Replace if faulty.
Check Brake Fluid Level
- If the brake fluid is low, fill it to the recommended level. This can sometimes resolve traction control issues.
- If fluid is low, check for leaks in the brake system.
Test Drive
- After repairs, take the vehicle for a test drive. Monitor the warning light and verify that the traction control system functions correctly.
Final Scan
- After the test drive, scan the vehicle again to ensure no new codes have appeared and that the traction control warning light remains off.
