TERMINAL LAYOUT

PHYSICAL VALUES

NOTE:

• The hybrid vehicle control ECU is located behind the passenger side instrument lower panel. For this inspec-

tion, remove passenger side instrument lower panel.

• Specification data are reference values and are measured between each terminal and ground.

• Pulse signal is measured by CONSULT-III.

CAUTION:

Do not use the hybrid vehicle control ECU ground terminals when measuring input/output voltage.

Doing so may result in damage to the hybrid vehicle control ECUs transistor. Use a ground other than

the hybrid vehicle control ECU terminals, such as the ground.
