Frequently asked questions
One parking sensor is not working in Hyderabad — how to identify which one?
Parking sensor ECUs typically beep a specific number of times on startup to identify faulty sensors. Check your owner's manual for the fault code pattern. If the sensor is silent when the system should beep, it's either dirty, cracked, or has failed. Clean all 4 rear sensors with a damp cloth first — mud accumulation from Hyderabad's monsoon roads is a very common cause of single sensor failure.
