6. 

CHECK VIAS CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect VIAS control solenoid valve harness connector.

3.

Turn ignition switch ON.

4.

Check voltage between terminal 1 and ground with CONSULT-II
or tester.

OK or NG

OK

>> GO TO 8.

NG

>> GO TO 7.

7. 

DETECT MALFUNCTIONING PART

Check the following.

●

Harness connectors E2, F32

●

Harness for open or short between VIAS control solenoid valve and IPDM E/R

●

Harness for open or short between VIAS control solenoid valve and ECM

>> Repair harness or connectors.

8. 

CHECK VIAS CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Check harness continuity between ECM terminal 29 and VIAS control solenoid valve terminal 2.
Refer to Wiring Diagram.

4.

Also check harness for short to ground and short to power.

OK or NG

OK

>> GO TO 9.

NG

>> Repair open circuit or short to ground or short to power in harness or connectors.

VIAS CONTROL SOLENOID VALVE

 With CONSULT-II

1.

Reconnect harness connectors disconnected.

2.

Turn ignition switch ON.

3.

Perform “VIAS SOL VALVE” in “ACTIVE TEST” mode.

4.

Check air passage continuity and operation delay time under the
following conditions.

Operation takes less than 1 second.

 Without CONSULT-II

Check air passage continuity and operation delay time under the fol-
lowing conditions.

Operation takes less than 1 second.

VACUUM TANK

1.

Disconnect vacuum hose connected to vacuum tank.

2.

Connect a vacuum pump to the port (A) of vacuum tank.

3.

Apply vacuum and make sure that vacuum exists at the port (B).
