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.

Pulse signal is measured by CONSULT-II.

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