Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Replace Brake Pressure Sensor

Tools Required: Multimeter, socket set, torque wrench, brake cleaner.
Remove the sensor connector by pressing the locking tab and pulling it away.
Using a socket, remove the brake pressure sensor from the brake line.
Inspect the old sensor for any wear or damage.
Clean the mounting area on the brake line with brake cleaner.
Install the new brake pressure sensor by threading it into the brake line and tightening to the manufacturer's specified torque (typically around 15 Nm, but verify with service manual).
Reconnect the sensor connector ensuring it clicks into place.

3. Reconnect Battery and Test

Reconnect the battery terminal securely.
Start the vehicle and check for any warning lights on the dashboard.
Conduct a test drive to ensure proper braking functionality and monitor for the C1411 code reappearing.
