PREPARATION E
1. ECM is located behind the glove box. For this inspection,
remove glove box.
2. Remove ECM harness protector.

H
MBIB0155E

3. When disconnecting ECM harness connector, loosen it with

levers as far as they will go as shown at right. I
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.
J
● 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.
CAUTION: M
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.
