Fault analysis:
When picking up the car, the computer reads the fault code: the front door handle smart sensor is short-circuited or open-circuited!
The actual test shows that the main driver’s door handle has no response to smart entry, and the other doors can be locked and unlocked normally!
Since the smart sensor is integrated on the door handle, the main driver’s door handle was disassembled and short-circuited and burned marks were found!
The main driver’s door wiring harness was also short-circuited and burned!

Solution:
Replace the main driver’s door wiring harness and replace the main driver’s door handle!
