System Check Procedure

EFI SYSTEM CHECK PROCEDURE

1. Remove the ECU cover under the center console.
2. Remove the ECU with the harness.
3. Perform all voltage measurements with the connectors connected.
4. Verify that the battery voltage is 11 V or above when the ignition switch is ON.

Voltage Measurement




The EFI circuit can be checked by measuring the voltage at the wiring connectors of the ECU.

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

Standard Values

NOTE: If there is any problem, refer to the test number on the left hand side of the standard values chart.

Resistance Measurement

Check the resistance between each terminal of the wiring connectors.




- Disconnect the connectors from the ECU.




- Measure the resistance at each terminal.

CAUTION:
- Do not touch the ECU terminals.
- The tester probe should be inserted into the wiring connector from the wiring side.
