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 2AO
-
- Variable intake-air shutter valve actuator terminal B and PCM terminal 2AS
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 GND
-
- Variable intake-air shutter valve actuator terminal B and power supply
-
- Variable intake-air shutter valve actuator terminal B and body GND
