VARIABLE INDUCTION AIR CONTROL SYSTEM (VIAS)
Revision: 2006 December 2006 FX35/FX45
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

Diagnostic ProcedureNBS004GQ
1. CHECK OVERALL FUNCTION
With CONSULT-II
1. Start engine and warm it up to normal operating temperature.
2. Perform “VIAS SOL VALVE” in “ACTIVE TEST” mode with CON- SULT-II.
3. Turn VIAS control solenoid valve ON and OFF, and make sure that power valve actuator (1) rod moves.
Without CONSULT-II
1. Lift up the vehicle.
2. Start engine and warm it up to normal operating temperature.
3. Make sure that power valve actuator (1) rod moves when chang- ing the gear position to N and D alternately.
OK or NG
OK >> INSPECTION END
NG (With CONSULT-II)>>GO TO 2.
NG (Without CONSULT-II)>>GO TO 3.
