Vehicle Damage Warnings

MAINTENANCE PRECAUTIONS
1. IN EVENT OF ENGINE MISFIRE, FOLLOWING PRECAUTIONS SHOULD BE TAKEN
- Check proper connection of battery terminals, etc.
- Handle high-tension cords carefully.
- After repair work, check that the ignition coil terminals and all other ignition system lines are reconnected securely.
- When cleaning the engine compartment, be especially careful to protect the electrical system from water.
2. PRECAUTIONS WHEN HANDLING OXYGEN SENSOR
- Do not allow oxygen sensor to drop or hit against an object.
- Do not allow the sensor to come into contact with water.

IF VEHICLE IS EQUIPPED WITH MOBILE RADIO SYSTEM
(HAM, CB, ETC.)
If the vehicle is equipped with a mobile communication system, refer to the applicable service precautions.

AIR INDUCTION SYSTEM
1. Separation of the engine oil dipstick, oil filler cap. PCV hose, etc. may cause the engine to run out of tune.
2. Disconnection, looseness or cracks in the parts of the air induction system between the throttle body and cylinder head will allow air suction and cause the engine to run out of tune.


ELECTRONIC CONTROL SYSTEM
1. Before removing SFI wiring connectors, terminals, etc., first disconnect the power by either turning the ignition switch OFF or disconnecting the negative (-) terminal cable from the battery.

HINT: Always check the diagnostic trouble code before 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 even slight terminal contact can further troubles.
5. Do not open the ECM cover.





6. When inspecting during rainy weather, take care to prevent 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.
- Release the lock and pull out the connector, pulling on the connectors.
- Fully insert the connector and check that it is locked.





9. When inspecting a connector with a volt/ohmmeter
- Carefully take out the water-proofing rubber if it is a water-proof type connector.
- Insert the test probe into the connector from the wiring side when checking the continuity, amperage or voltage.
- Do not apply unnecessary force to the terminal.
- After checking, install the water-proofing rubber on the connector securely.





10. Use SST for inspection or test of the injector or its wiring connector. SST 09842-30070
