GND | B+ | Clockwise

## Circuit Open/Short Inspection

1. Inspect the following wiring harnesses for an open or short circuit. (Continuity check)

### Open circuit

  • If there is no continuity, the circuit is open. Repair or replace the wiring harness.
  - VTCS shutter valve actuator terminal A and PCM terminal 2AJ
  - VTCS shutter valve actuator terminal B and PCM terminal 2AF

### Short circuit

  • If there is continuity, the circuit is shorted. Repair or replace the wiring harness.
  - VTCS shutter valve actuator terminal A and power supply
  - VTCS shutter valve actuator terminal A and body GND
  - VTCS shutter valve actuator terminal B and power supply
  - VTCS shutter valve actuator terminal B and body GND
