TROUBLESHOOTING WITH VOLT/OHMMETER PREPARATION FOR TROUBLESHOOTING 1. Remove the glove box door and glove box. 2. Remove the ECU with wire harness. EFI SYSTEM CHECK PROCEDURE NOTE: 1. The EFI circuit can be checked by measuring the resistance and voltage at the wiring connectors of the ECU. 2. Perform all voltage measurement with the connectors connected. 3. Verify that the battery voltage is 11V or above when the ignition switch is ON. Using a voltmeter, measure the voltage at each terminal of the wiring connector. NOTE: If there is any problem, see TROUBLESHOOTING FOR EFI ELECTRONIC CIRCUIT WITH VOLT/ OHMMETER.
