Repair Instructions

Step 1: Resolve Any Identified DTCs

Clear Codes:
- If you’ve retrieved codes, clear them using the OBD-II scanner and take the vehicle for a test drive to see if the light comes back on.
Address Specific Codes:
- If the light returns, address the specific issues indicated by the DTCs:
  - Wheel Speed Sensor Issues: Replace faulty wheel speed sensors.
  - Yaw Rate Sensor Issues: Inspect and replace if necessary.
  - Brake System Issues: Check for ABS module faults or brake fluid leaks.

Step 2: Check and Top Off Brake Fluid

Inspect Brake Fluid:
- If low, fill the brake fluid reservoir with the recommended DOT brake fluid type (check owner’s manual).

Step 3: Inspect and Clean Wheel Speed Sensors

Remove Wheel:
- Jack up the vehicle and remove the wheel to access the wheel speed sensors.
Clean Sensors:
- Using electrical contact cleaner, clean the wheel speed sensor and the mounting area to ensure no debris is causing interference.
Reconnect and Secure:
- Reconnect any loose harnesses ensuring they are secured and not corroded.

Step 4: Inspect Tire Pressure

Check All Tires:
- Ensure all tires are at the manufacturer-recommended pressure.
- Inflate to the correct pressure if necessary.

Step 5: Check Battery Condition

Measure Voltage:
- If the battery voltage is below 12.4 volts, recharge or replace the battery.
Clean Battery Terminals:
- Clean any corrosion from battery terminals and ensure a tight connection.

Final Steps

Test Drive: After performing the above checks and repairs, take the vehicle for a test drive to ensure the stability control light does not return.
Re-scan if Necessary: If the light remains on, re-scan the vehicle for codes and address any new issues that may arise.

Conclusion

If the stability control light persists after following these steps, it is recommended to consult with a qualified technician or take the vehicle to a Toyota dealership for further diagnosis. The issue could be related to more complex systems within the vehicle's stability control module.
