System Check Procedure

EFI SYSTEM CHECK PROCEDURE

PREPARATION
Remove the ECU with wire harness.

NOTE:
- The EFI circuit can be checked by measuring the voltage at the wiring connectors of the ECU.
- Perform all voltage measurements with the connectors connected.




- Verify that the battery voltage is 12V or above when the ignition switch is ON.

Using a voltmeter with high-impedance (10 k/V minimum), measure the voltage at each terminal of the wiring connector.
