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.
- Variable intake air shutter valve actuator terminal A and PCM terminal 2AJ
- Variable intake air shutter valve actuator terminal B and PCM terminal 2AI

Short circuit

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