Issue: Stability Control System Malfunction in Toyota Camry XV70

When experiencing issues with the stability control system (Vehicle Stability Control - VSC) in your 2018-2024 Toyota Camry XV70, you may notice the following symptoms:

Repair Instructions

Step 1: Clear DTCs

After diagnosing, clear the DTCs using the OBD-II scanner and take the vehicle for a test drive to see if the warning lights reappear.

Step 2: Replace Faulty Wheel Speed Sensors

If DTC indicates a specific wheel speed sensor issue:
1. Jack up the vehicle and secure it with jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Disconnect the sensor connector.
4. Remove the mounting bolts and take out the faulty wheel speed sensor.
5. Install the new sensor in reverse order.
6. Reconnect the sensor connector and reinstall the wheel.
7. Repeat steps for other wheels if necessary.

Step 3: Address ABS Module Issues

If ABS module malfunction is indicated:
1. Disconnect the battery by removing the negative terminal.
2. Remove the ABS control module from its mounting bracket (usually located near the brake master cylinder).
3. Disconnect the wiring harness and replace the module with a new one.
4. Reconnect the battery, and using the OBD-II scanner, perform a system initialization if required.

Step 4: Brake Fluid Level and Condition

If the brake fluid was low or contaminated:
1. Remove the brake fluid reservoir cap.
2. Fill with the appropriate brake fluid (check specifications in the owner’s manual).
3. Bleed the brake system if necessary to remove air bubbles.

Step 5: Final Testing

After repairs, clear any DTCs again and conduct a test drive. Monitor the dashboard for any warning lights and assess vehicle handling to ensure stability control is functioning correctly.

Conclusion

If, after performing these steps, the stability control system continues to malfunction, it may require advanced diagnostics or professional service. This can include checking the vehicle’s CAN bus communication or inspecting for other underlying issues not related directly to the VSC system. Always refer to the specific service manual for your model year for detailed specifications and procedures.
