ELECTRONIC FUEL INJECTION (EFI) SYSTEM CHECK PROCEDURE

NOTE:
- Perform all voltage measurements with the connectors connected.
- Verity that the battery voltage is 11 V or more when the ignition switch is at "ON".

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