With Automatic Transaxle

ELECTRONIC FUEL INJECTION (EFI) SYSTEM CHECK PROCEDURE

Preparation
(a) Disconnect the connectors from the engine and ECT ECU.





(b) Remove the locks as shown in the illustration so that the tester probe(s) can easily come in.

NOTICE: Pay attention to sections "A" and "B" in the illustration which can be easily broken.

(c) Reconnect the connectors to the engine and ECT ECU.





HINT:
- 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.
