Ensure the vehicle is parked on a level surface and the engine is off for safety.

2. Inspect and Clean Sensors

Locate the parking sensors on the front and rear bumpers.
Use a soft cloth dampened with cleaning solution to gently clean each sensor.
Ensure no dirt, ice, or debris obstructs the sensors.

3. Check for Fault Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn on the ignition without starting the engine.
Scan for any fault codes specifically related to parking sensors or the parking assist system.
Note any codes found for further inspection or repair.
