Inspection of ECM and Its CircuitsS7RS0B1104079
ECM and its circuits can be checked by measuring voltage, pulse signal and resistance with special tool connected.
CAUTION!
ECM cannot be checked by itself. It is strictly prohibited to connect voltmeter or ohmmeter to ECM
with ECM connectors disconnected from it.

Voltage Check
1) Remove ECM (1) from its bracke t referring to “ECM Removal and Installation in Section 1C”.
2) Connect special tool between EC M and ECM connectors securely.
Special tool
(A): 09933–06320
3) Check voltage and/or pulse signal us ing voltmeter (2) and oscilloscope (3).
NOTE
• As each terminal voltage is affected by battery voltag e, confirm that it is 11 V or more when ignition
switch is turned ON.
• Voltage with asterisk (*) cannot be measured with voltmeter because it is pulse signal. Use oscilloscope for its check if necessary.
• Before this inspection, be sure to read the “Precautions of ECM Circuit Inspection”.
