System Check Procedure

PREPARATION
1. Remove the glove box door and glove box.
2. Remove the Electronic Control Unit (ECU) with wire harness.

ELECTRONIC FUEL INJECTION (EFI) SYSTEM CHECK PROCEDURE






NOTE:
1. The EFI circuit can be checked by measuring 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".

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