System Check Procedure

ELECTRONIC FUEL INJECTION (EFI) SYSTEM CHECK PROCEDURE

Preparation
a. Disconnect the connectors from the ECU.






b. Remove the locks as shown so that the tester probe(s) can easily come in.

CAUTION: Pay attention to sections "A" and "B" in the illustration which can be easily broken.

c. Reconnect the connectors to the ECU.





NOTE: Perform all voltage measurements with the connectors connected. Verify that the battery voltage is 11 V or more when the ignition switch is in "ON" position.








Terminal Identification








Standard Voltage at ECU Wiring Connectors
Using a voltmeter with high impedance (10 k-ohms/V minimum), measure the voltage at each terminal of the wiring connectors.

NOTE: If there are any problems, proceed with test indicated in left column.
