PREPARATION
1.
ECM is located behind the glove box. For this inspection,
remove glove box.
2.
Remove ECM harness connector.
3.
When disconnecting ECM harness connector, loosen it with
levers as far as they will go as shown at right.
4.
Connect a break-out box (SST) and Y-cable adapter (SST)
between the ECM and ECM harness connector.
●
Use extreme care not to touch 2 pins at one time.
●
Data is for comparison and may not be exact.
ECM INSPECTION TABLE
Specification data are reference values 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 result in dam-
age to the ECMs transistor. Use a ground other than ECM terminals, such as the ground.

INSPECTION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1.
Turn ignition switch OFF.
2.
Connect “CONSULT-II” and “CONSULT-II CONVERTER” to
data link connector, which is located under LH dash panel near
the hood opener handle.
3.
Turn ignition switch ON.
