If the circuit condition is not as specified, then the parking brake switch is faulty.
Checking the brake light switch
1. Check continuity between terminals "1" And "2" brake light switch connector. When the pedal is pressed, the conductivity should be, when the pedal is released, there should not be any conductivity. Otherwise, replace the brake light switch.
