The electronic controlled engine mount control solenoid valve controls the intake manifold vacuum signal for electronic controlled engine mount. The electronic controlled engine mount control solenoid valve is moved by
ON/OFF signal from the ECM. When the solenoid is OFF, the vacuum signal from the intake manifold is cut.
When the solenoid is ON, the intake manifold vacuum signal is sent to the electronic controlled engine mount.
Check vacuum hoses and vacuum gallery for clogging, cracks or improper connection. Refer to See: System Description. Is the Inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace vacuum hoses and vacuum gallery. 3.CHECK ELECTRONIC CONTROLLED ENGINE MOUNT CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT
Disconnect electronic controlled engine mount control solenoid valve harness connector.
Check the voltage between front electronic controlled engine mount harness connector and ground.
Is the Inspection result normal?
YES >> GO TO 5.
NO >> GO TO 4. 4.DETECT MALFUNCTIONING PART
Check the following.
10 A fuse (No. 3)
Fuse block (J/B) connector E6
Harness connectors E3, F1
Harness for open or short between electronic controlled engine mount control solenoid valve and fuse >> Repair open circuit, short to ground or short to power in harness or connectors.
5.CHECK ELECTRONIC CONTROLLED ENGINE MOUNT CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
Disconnect ECM harness connector.
Check the continuity between ECM harness connector and electronic controlled engine mount control solenoid valve harness connector.
Also check harness for short to ground and short to power. Is the Inspection result normal?
YES >> GO TO 6.
NO >> Repair open circuit, short to ground or short to power in harness connectors. 6.CHECK ELECTRONIC CONTROLLED ENGINE MOUNT CONTROL SOLENOID VALVE
Refer to See: Component Inspection.
Is the Inspection result normal?
YES >> GO TO 7.
NO >> Replace electronic controlled engine mount control solenoid valve. 7.CHECK ELECTRONIC CONTROLLED ENGINE MOUNT
