Inspection of ECM and Its Circuits

Precautions: General safety (00)

NOTE:
•As each terminal voltage is affected by battery voltage, check that battery voltage is 11 V or more when ignition is “ON”.
•Voltage with asterisk (*) cannot be measured with voltmeter because it is pulse signal.
Use oscilloscope for its check.
•Before performing this inspection, read “Precautions of ECM Circuit Inspection” under Precautions for Engine (D16AA).
