DTC P0011, P0021 IVT CONTROL

Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULU-II.

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.

: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
