3. Check the continuity between multi-way control valve harness connector and ECM harness connector.

4. Also check harness for short to power.
Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace error-detected parts.

3.

CHECK MULTI-WAY CONTROL VALVE POSITION SENSOR INPUT SIGNAL CIRCUIT

1. Check the continuity between multi-way control valve harness connector and ECM harness connector.

2. Also check harness for short to ground and to power.
Is the inspection result normal?

YES

>> GO TO 4.
