ECM Harness Connector Terminal Layout
EBS00N43
ECM Terminals and Reference ValueEBS00N44
PREPARATION
1. ECM is located behind the glove box. For this inspection,
remove glove box.
2. Remove ECM harness protector.
3. Perform all voltage measurements with the connector con-
nected. Extend tester probe as shown to perform tests easily.
●Open harness securing clip to make testing easier.
●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 body ground.
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.
