Pinout Values and Diagnostic Parameters

PREPARATION OF TROUBLESHOOTING

1. Remove the glove box door and glove box.

2. Remove the ECU with the wire harness.

EFI SYSTEM CHECK PROCEDURE

1. The Electronic Fuel Injection (EFI) circuit can be checked by measuring the resistance and the voltage at the wiring connectors of the ECU.

2. Perform all voltage measurements with the connectors connected.

3. Verify that the battery voltage is 11 V or above when the ignition switch is "ON".





4. Using a voltmeter, measure the voltage at each terminal of the wiring connector.

Component Tests and General Diagnostics

INSPECTION OF WIRING CONNECTOR LINE

CAUTION:

- Do not touch the Electronic Controlled Unit (ECU) terminals.

- The tester probe should be inserted into the wiring connector from the wiring side.

MEASURE RESISTANCE OF ECU WIRING CONNECTORS

1. Remove the glove box.

2. Disconnect the wiring connectors from the ECU.





3. Using an ohmmeter, measure the resistance between each terminal of the wiring connector.
