ELECTRONIC CONTROL
(a)
REMOVAL AND INSTALLATION OF BATTERY TERMI-
NAL
(1)
Before performing electrical work, disconnect the
battery negative (–) terminal cable beforehand so
as to prevent burnt–out damage by short.
(2)
When disconnecting and installing the terminal
cable, turn the ignition switch and lighting switch
OFF, and loosen the terminal nut completely. Per-
form these operations without twisting or prying the
terminal.
(3)
When the battery terminal is removed, all the me-
mories of the clock, radio, DTCs, etc. will be erased.
So before removing it, check them and note them
down.
(4)
When the battery terminal is disconnected, the slid-
ing roof position memory is erased.
Make sure to reset the sliding roof zero point See

(b)
HANDLING OF ELECTRONIC PARTS
(1)
Do not open the cover or case of the ECU unless
absolutely necessary (If the IC terminals are
touched, the IC may be destroyed by static electric-
ity).
(2)
To disconnect electronic connectors, pull the con-
nector itself, not the wires.
(3)
Be careful not to drop electronic components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced and not be reused.
(4)
When cleaning the engine with steam, protect the
electronic components, air filter and emission–re-
lated components from water.
(5)
Never use an impact wrench to remove or install
temperature switches or temperature sensors.
(6)
When checking the continuity at the wire connector,
insert the tester probe carefully to prevent terminals
from bending.

REMOVAL AND INSTALLATION OF FUEL CONTROL PARTS
(a)
PLACE FOR REMOVING AND INSTALLING OF FUEL SYSTEM PARTS
(1)
Work in a place with good air ventilation and without anything flammable such as welder, grinder,
drill, electric motor or stove in the surroundings.
(2)
Never work in a place such as a pit or nearby a pit, as there is a possibility that vaporized fuel
is filled in those places.
