why does my Toyota Highlander XU70 (2020-Present) feel like it's losing traction

Solution

1. Tire Inspection

• Sub-steps:
  • Check tire pressure with a tire pressure gauge; adjust to manufacturer's specifications if necessary.
  • Inspect tire tread depth using a tread depth gauge; replace tires if tread is below 2/32 inches.
  • Look for visible damage, such as cuts, bulges, or uneven wear patterns.

2. Traction Control System Assessment

• Sub-steps:
  • Connect an OBD-II scanner to the vehicle's diagnostic port and scan for any active error codes.
  • Address any codes related to the traction control system by following the manufacturer's troubleshooting guidelines.
  • Clear the error codes and conduct a test drive to see if the warning light reappears.

3. Sensor and System Check

• Sub-steps:
  • Locate the wheel speed sensors on each wheel; inspect wiring and connectors for damage or corrosion.
  • Clean the sensor surfaces with a soft cloth to remove any debris or dirt.
  • If necessary, replace any faulty sensors based on diagnostic findings.

4. Alignment and Suspension Check

• Sub-steps:
  • Use a wheel alignment tool to check the alignment settings; adjust as needed to match specifications.
  • Inspect suspension components, including bushings and shocks, for signs of wear; replace any damaged parts.
  • Test drive the vehicle to verify stability and traction improvement.
