what does the C1241 code indicate for my Toyota Highlander Fourth Generation (2020-present)?

Solution

1. Preparation

• Gather necessary tools and safety equipment.
• Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Replace Brake Pressure Sensor

• Tools Required: Wrench set, socket set, multimeter, brake cleaner, safety goggles, gloves
• Locate the brake pressure sensor on the master cylinder.
• Disconnect the electrical connector from the brake pressure sensor.
• Use a wrench to unscrew the sensor from the master cylinder.
• Inspect the sensor's threads and O-ring; clean the area with brake cleaner.
• Install the new brake pressure sensor and tighten it to manufacturer specifications (check service manual for torque values).
• Reconnect the electrical connector to the new sensor.

3. Refill and Bleed Brake System

• Refill the master cylinder with the appropriate brake fluid (refer to the owner's manual for specifications).
• Bleed the brake system to remove any air trapped in the lines:
  • Start with the wheel farthest from the master cylinder and work your way closer.
  • Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve until fluid flows without bubbles.
• Ensure all wheels are bled properly.

4. Reconnect Battery and Clear Codes

• Reconnect the negative terminal of the battery.
• Use the OBD-II scanner to clear the C1241 code from the system.
• Start the vehicle and monitor for any warning lights.
