Values/Status

HAC-94

< ECU DIAGNOSIS >

[AUTOMATIC AIR CONDITIONER]

ECM

*: Throttle position sensor 2 signal is converted by ECM internally. Thus, it differs from ECM terminal voltage signal.

TERMINAL LAYOUT

PHYSICAL VALUES

NOTE:

• ECM is located in the engine room left side near inverter with converter assembly.

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

• Pulse signal is measured by CONSULT-III.

• If necessary, activate “INSPECTION MODE 1” (

HBC-104

).

CAUTION:

Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-

age to the ECMs transistor. Use a ground other than ECM terminals, such as the ground.
