Description
EBS0156I
The load from the turbocharger boost control solenoid valve controls
the actuator. By changing the variable nozzle vane opening through
the rods, the intake air volume is adjusted.
The turbocharger boost control solenoid valve is moved by ON/OFF
pulse from the ECM. The longer the ON pulse, the charge air pres-
sure rises.
ECM Terminals and Reference Value
EBS0156J
Specification data are reference valves, and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may damage the
ECM's transistor. Use a ground other than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
