Electronic Control System

SFI SYSTEM

1. Before working on the fuel system, disconnect the negative (-) terminal cable from the battery.

HINT: Any diagnostic trouble coda retained by the computer will be erased when the negative (-) terminal cable is disconnected. Therefore, if necessary. read the diagnosis before disconnecting the negative (-) terminal cable from the battery.

2. Do not smoke or work near an open flame when working on the fuel system.
3. Keep gasoline away from rubber or leather parts.

ELECTRONIC CONTROL SYSTEM

1. Before removing SFI wiring connectors, terminals, etc., first disconnect the power by either turning the ignition switch to LOCK or disconnecting the negative (-) terminal cable from the battery.
2. When installing the battery. be especially careful not to incorrectly connect the positive (+) and negative (-) cables.
3. Do not permit parts to receive a severe impact during removal or installation. Handle all SFI parts carefully. especially the ECM.
4. Do not be careless during troubleshooting as there are numerous transistor circuits and contact with terminals can cause further trouble.
5. Do not open the ECM cover.
6. When inspecting during rainy weather, take care to prevent the entry of water. Also. when washing the engine compartment. prevent water from getting on the SFI parts and wiring connectors.
7. Parts should be replaced as an assembly.
8. Care is required when pulling out and inserting wiring connectors.
(a) Release the lock and pull out the connector, pulling the connectors.
(b) Fully insert the connector and check that it is locked.
9. When inspecting a connector with a volt/ohmmeter.
(a) Carefully take off the water-proofing rubber if it is a water-proof type connector.
(b) Insert the tester probe into the connector from the wiring side when checking the continuity. amperage or voltage.
(c) Do not apply unnecessary force to the terminal.
(d) After checking, install the water-proofing rubber securely on the connector.





10. Use SST for inspecting or testing the injector or its wiring connector. SST 09842-30070
