7. ELECTRONIC CONTROL SYSTEM
(a) 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.
(b) When installing the battery, be especially careful not to in-
correctly connect the positive (+) and negative (±) cable
terminals.
(c) Do not permit parts to receive a severe impact during re-
moval or installation. Handle all SFI parts carefully, espe-
cially the ECM.
(d) Do not be careless during troubleshooting as there are
numerous transistor circuits and even slight terminal con-
tact can further troubles.
(e) Do not open the ECM cover.
(f) When inspecting during rainy weather, take care to pre-
vent entry of water. Also, when washing the engine
compartment, prevent water from getting on the SFI parts
and wiring connectors.
(g) Parts should be replaced as an assembly.
(h) Care is required when pulling out and inserting wiring con-
nectors.
(1) Release the lock and pull out the connector, pulling
on the connectors.
(2) Fully insert the connector and check that it is locked.
(i) When inspecting a connector with a volt/ohmmeter.
(1) Carefully take out the water±proofing rubber if it is
a water±proof type connector.
(2) Insert the test probe into the connector from wiring
side when checking the continuity, amperage or
voltage.
(3) Do not apply unnecessary force to the terminal.
(4) After checking, install the water±proofing rubber on
the connector securely.
(5) Use SST for inspection or test of the injector or its
wiring connector.
