ECU
INSPECTION OF ECU

Voltage at ECU Wiring Connectors:

1. MEASURE VOLTAGE OF ECU

NOTE:
(1) The ECU itself cannot be checked directly.
(2) The EFI circuit can be checked by measuring the resistance and voltage at the wiring connectors of the ECU.
Check the voltage at the wiring connectors.
^ Remove the right kick panel.
^ Turn the ignition switch ON.
^ Measure the voltage at each terminal.

NOTE :
1. Perform all voltage measurements with the connectors connected.
2. Verify that the battery voltage is 11V or above when the ignition switch is ON.

Resistance at ECU Wiring Connectors:

2. MEASURE RESISTANCE OF ECU

CAUTION:
(1) Do not touch the ECU terminals.
(2) The tester probe should be inserted into wiring connector from the wiring side.
Check the resistance between each terminal of the wiring connector.
^ Remove the right kick panel.
^ Unplug the wiring connectors from the ECU.
^ Measure the resistance between each terminal of the wiring connectors.
