4WD Automatic Transmission Only

INSPECTION OF ENGINE (ENGINE AND ECT) ECU

HINT:
* The ECU itself cannot be checked directly.
* The EFI circuit can be checked by measuring the resistance and voltage at the wiring connectors of the ECU.






1. MEASURE VOLTAGE OF ECU

Voltage At ECU Wiring Connectors (4WD & Automatic Trans.):

Check the voltage between each terminal of the wiring connectors.
* Remove the right kick panel.
* Turn the ignition switch to ON.
* Measure the voltage at each terminal.

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






2. MEASURE RESISTANCE OF ECU

NOTICE:
* Do not touch the ECU terminals.
* The tester probe should be inserted into the wiring connector from the wiring side.

Resistance At Engine (and ECT) ECU Wiring Connectors:

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.
