⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems to prevent short circuits.

Symptoms

•Parking sensor warning light illuminated on the dashboard
•No audible alerts when approaching obstacles
•Inconsistent sensor activation or deactivation
•Reduced detection range or missed obstacles
•Error codes related to parking sensors may be present

Diagnostic Steps

1
Inspect the parking sensor area for physical damage or obstructions (dirt, ice, or debris).
2
Scan the vehicle's OBD-II system for any error codes related to parking sensors.
3
Check the wiring and connectors leading to each parking sensor for corrosion or loose connections.
4
Verify the functionality of the parking sensor module by testing power and ground with a multimeter.
5
Clean the sensor lenses with a soft cloth to ensure no dirt or grime is affecting performance.
6
Ensure that the vehicle's battery is in good condition, as low voltage can affect sensor operation.
