− SFI SYSTEM
When installing the battery, be especially careful to cor-
rectly connect the positive (+) and negative (−) cables.
Do not give a severe impact to the SFI parts during remov-
al or installation. Handle all SFI parts carefully, especially
the ECM.
Be careful during troubleshooting. Numerous transistor
circuits are used and even slight terminal contact can
cause further trouble.
Do not open the ECM cover.
When inspecting during rainy weather, take care to pre-
vent entry of water. Also, when washing the engine
compartment, prevent water from getting into the SFI
parts and wiring connectors.
Parts should be replaced as an assembly.
Care should be taken when pulling out and inserting wir-
ing connectors.
(1) Release the lock and pull out the connector, pulling
on the connectors.
(2) Fully insert the connector and check that it is locked.
Use SST for inspection or test of the injector or its wiring
connector.

(5) Disconnect the high fuel pressure line.
(6) Reconnect the fuel pump connector.
When connecting the union bolt (fuel pressure pulsation
damper) on the high pressure pipe union, observe the fol-
lowing procedures:
(1) Always use 2 new gaskets.
(2) Tighten the union bolt by hand.
