When the brake warning light illuminates on your 2022 Toyota Camry XV70, it is essential to address the issue promptly to ensure your safety and the reliability of your vehicle. Below are the symptoms, diagnostic steps, tools required, and repair instructions.

Repair Instructions

Topping Off Brake Fluid
- If the fluid was low, top it off using the correct type of brake fluid. Ensure the cap is securely tightened after filling.
Repairing Any Leaks
- If leaks were found, replace any faulty components (master cylinder, brake lines, calipers) as needed. Ensure all connections are secure and leak-free.
Replacing Brake Pads or Rotors
- If brake pads are worn:
  - Remove the caliper bolts and remove the caliper.
  - Replace the old brake pads with new ones.
  - If the rotors are damaged, replace them as well.
  - Reassemble the caliper and ensure all bolts are torqued to specification.
Repairing or Replacing Brake Sensors
- If the wear sensor is damaged, disconnect it from the wiring harness and replace it with a new one.
Resetting the Brake Warning Light
- After repairs, the brake warning light may need to be reset. This can be done via the OBD-II scanner by clearing the codes or by disconnecting the battery for a few minutes.
Test Drive
- Conduct a test drive to ensure that the brake system functions properly and that the warning light does not reappear.

Final Check

After completing the repair, ensure all tools are removed from the vehicle, and the brake system is functioning correctly before driving normally.

If the brake warning light remains on after these steps or if you are unsure about any repairs, it is advisable to consult a professional technician or visit a Toyota dealership for further diagnosis and service.
