Battery voltage is supplied at all times to the ignition key warning beeper circuit in the integrated control unit. When the ignition key switch is closed, the integrated control unit senses ground at G401. When the driver's door is opened, the left door switch closes and the GRN/BLU wire is grounded. The beeper will sound until the door is closed and the left door switch opens.
