(8) Oil or water should not be put on the front seat outer belt and the front seat outer belt should be
cleaned with the appropriate detergents.
(i) AIRBAG SENSOR ASSEMBLY (1) Never reuse the airbag sensor assembly involved in a collision where the\
SRS has deployed.
(2) The connectors to the airbag sensor assembly should be connected or disc\
onnected with thesensor mounted on the floor. If the connectors are connected or disconnected while the airbag
sensor assembly is not mounted to the floor, it could cause an undesired ignition of the supple-
mental restraint system.
(3) Work must be started after 90 seconds from the time the ignition switch is t\
urned to the ºLOCKº position and the negative (±) terminal cable is disconnected from the battery, even if only loosen-
ing the set bolts of the airbag sensor assembly.
(j) WIRE HARNESS AND CONNECTOR
(1) The SRS wire harness is integrated with the instrument panel wire harness a\
ssembly. All connec-tors in the system are a standard yellow color. If the SRS wire harness becomes disconnected
or the connector becomes broken due to an accident, etc., repair or repl\
ace it.
3. ELECTRONIC CONTROL
(a) REMOVAL AND INSTALLATION OF BATTERY TERMI-NAL
(1) Before performing electronic work, disconnect thebattery negative (±) terminal cable beforehand in
order to prevent it from shorting and burning out.
(2) When disconnecting and insta lling 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 cable is removed, the memories of the clock, radio, DTCs, etc. are erased.
So before removing it, check them and make a note
of their settings.
(4) When the battery negative (±) terminal cable is dis- connected, memories of various systems are
erased. Therefore, refer to the PRE±CHECK for
each system to make sure whether or not the sys-
tem needs to be initialized after the battery negative

(±) terminal cable is disconnected. If necessary, be
sure to initialize the system.
(b) HANDLING OF ELECTRONIC PARTS (1) Do not open the cover or case of the ECU unlessabsolutely necessary (If the IC terminals are
touched, the IC may be rendered inoperative by
static electricity).
(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.
4. 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 that could ca\
use combustionaround you such as a welder, grinder, drill, electric motor or stove.
(2) Never work in a place such as a pit or nearby a pit, as there is a possi\
bility that vaporized fuel will collect in those places.
(b) REMOVING AND INSTALLING OF FUEL SYSTEM PARTS (1) Prepare a fire extinguisher before starting operations.
(2) To prevent static electricity, install a ground on the fuel changer, vehicle and fuel tank, and donot spray much water so as to prevent slipping.
(3) Never use any electric equipment like an electric motor or a working lig\
ht, as they may create
sparks or a high temperature.
(4) Never use an iron hammer, as it may create sparks.
(5) Dispose of shop rags containing fuel deposits separately.
5. REMOVAL AND INSTALLATION OF ENGINE INTAKEPARTS
(a) If any metal tip is mixed in the inlet pass, this may give a bad effect to the engine and turbocharger.
(b) When removing and installing the inlet system parts,
close the opening of the removed inlet system parts and
the engine with a clean waste cloth or gum tape.
(c) When installing the inlet system parts, check that there is no mixing of a metal tip.

6. HANDLING OF HOSE CLAMPS
(a) Before removing the hose, check the depth of the insert-
ing portion and the clamp position to restore it surely.
(b) Change a deformed or dented clamp for a new one.
(c) In case of reusing a hose, attach the clamp on the clamp track portion of the hose.
(d) For a spring type clamp, adjust it by adding force to the
arrow mark direction after the installation.
7. FOR VEHICLES EQUIPPED WITH MOBILE COMMU- NICATION SYSTEMS
(a) Install the antenna as far away from the ECU and sensors of the vehicle electronic systems as possible.
(b) Install an antenna feeder at least 20 cm (7.87 in.) away from the ECU and sensors of the vehicle electronic sys-
tems. For details of the ECU and sensors locations, refer
to the section on applicable components.
(c) Prevent the antenna feeder from getting entangled with the other wiring, and keep the antenna feeder separate
from other wiring as much as possible.
(d) Check that the antenna and feeder are correctly adjusted.
(e) Do not install any high±powered mobile communication system.
8. FOR VEHICLES EQUIPPED WITH TRACTION CONTROL (TRC) SYSTEM
(a) NOTICES WHEN USING 2±WHEEL DRUM TESTER
(1) When using a 2±wheel drum tester such as a speedometer tester, a combination tester ofspeedometer and brake, chassis dynamometer or else, always turn the TRC system off via the
TRC OFF switch before measurement.
NOTICE:
TRC system OFF condition can be confirmed by the indication, ºTRC OFF\
º, of the warning light in
the combination meter.
9. FOR VEHICLES EQUIPPED WITH VEHICLE SKIDCONTROL (VSC) SYSTEM
(a) NOTICES WHEN USING DRUM TESTER
(1) When using a drum tester, be sure to start the en-gine with the ignition OFF, and connect SST to the
terminals TS and CG of the DLC3 before measure-
ment in order to prohibit the VSC operation.

NOTICE:

Confirm that the VSC warning light blinks.

VSC system will be reset when the engine is re-
started.

Fasten the vehicle with lock chains.
(b) NOTICES OF RELATED OPERATIONS TO VSC (1) Do not carry out unnecessary installation and re-
moval as it might disorder the adjustment of related
parts to VSC.
(2) Be sure to carry out the preparation for operation and the confirmation of operation completion in ac-
cordance with the instruction of the text and when
the related operations to VSC are performed.
10. FOR VEHICLES EQUIPPED WITH CATALYTIC CONVERTER
CAUTION:
If a large amount of unburned gasoline flows into the converter, it may cause overheating and is a
fire hazard. To prevent this, observe the following precautions.
(a) Use only unleaded gasoline.
(b) Avoid prolonged idling. Avoid idling the engine for more than 20 minutes.
(c) Avoid a spark jump test. (1) Perform a spark jump test only when absolutely necessary. Perform this test as rapidly as pos-sible.
(2) While testing, never race the engine.
(d) Avoid a prolonged engine compression measurement. Engine compression measurements must be performed as rapidly as possible\
.
(e) Do not run the engine when the fuel tank is nearly empty. This may cause the engine to misfire and create an extra load on the converter.
