LEC515
Component Description
NGEC0929
When the air conditioner is on, the IACV-FICD solenoid valve sup-
plies additional air to adjust to the increased load.
ECM Terminals and Reference Value
NGEC0930
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 the ECM terminals, such as the ground.
