Pinout Values and Diagnostic Parameters

ECM Terminals and Reference Value

PREPARATION




1. ECM is located behind the instrument lower cover. For this inspection:
- Remove instrument lower cover.




2. Remove ECM harness protector.




3. Perform all voltage measurements with the connector connected. 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 ground.

CAUTION: Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor. Use a ground other than the ECM terminals, such as the ground.
