INTRODUCTION: REPAIR INSTRUCTION: PRECAUTION

PRECAUTION (Continued)

3. ELECTRONIC CONTROL





(a) REMOVAL AND INSTALLATION OF BATTERY TERMINAL
(1) Before performing electrical work, disconnect the cable from the negative (-) battery terminal to prevent component and wire damage caused by accidental short circuits.
(2) When disconnecting the cable, turn the engine switch and headlight switch off and loosen the cable nut completely. Perform these operations without twisting or prying the cable. Then disconnect the cable.
(3) Clock settings, radio settings, audio system memory, DTCs and other data are cleared when the cable is disconnected from the negative (-) battery terminal. Write down any necessary data before disconnecting the cable.





(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 rendered inoperative by static electricity.
(2) Do not pull the wires when disconnecting electronic connectors. Pull the connector itself.
(3) Do not drop electronic components, such as sensors or relays. If they are dropped on a hard surface, they should be replaced.
(4) When cleaning the engine with steam, protect the electronic components, air filter and emission-related components from water.
(5) Never use an impact wrench to remove or install temperature switches or temperature sensors.
(6) When measuring the resistance between terminals of a 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 FUEL SYSTEM PARTS
(1) Work in a location with good air ventilation that does not have welders, grinders, drills, electric motors, stoves, or any other ignition sources.
(2) Never work in a pit or near a pit as vaporized fuel will collect in those places.
(b) REMOVING AND INSTALLING FUEL SYSTEM PARTS
(1) Prepare a fire extinguisher before starting the operation.
(2) To prevent static electricity, install a ground wire to the fuel changer, vehicle and fuel tank, and do not spray the surrounding area with water. Be careful when performing work in this area, as the work surface will become slippery. Do not clean up gasoline spills with water, as this may cause the gasoline to spread, and possibly create a fire hazard.
(3) Avoid using electric motors, work lights and other electric equipments that can cause sparks or high temperatures.
(4) Avoid using iron hammers as they may create sparks.
(5) Dispose of fuel-contaminated cloth separately using a fire resistant container.
5. REMOVAL AND INSTALLATION OF ENGINE INTAKE PARTS





(a) If any metal particles enter intake system parts, this may damage the engine.

(b) When removing and installing intake system parts, cover the openings of the removed parts and engine openings. Use adhesive tape or other suitable materials.
(c) When installing intake system parts, check that no metal particles have entered the engine or installed parts.





6. HANDLING OF HOSE CLAMPS
(a) Before removing a hose, check the clamp position so that it can be reinstalled in the same position.
(b) Replace any deformed or dented clamps with new ones.
(c) When reusing a hose, attach the clamp on the clamp track portion of the hose.
(d) For a spring type clamp, it may be necessary to spread the tabs slightly after installation by pushing in the direction of the arrows as shown in the illustration.





7. FOR VEHICLES EQUIPPED WITH MOBILE COMMUNICATION 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 systems. For details about the ECU and sensor locations, refer to the section on the applicable components.
(c) Keep the antenna and feeder separate from other wirings as much as possible. This will prevent signals sent from the communication equipment from affecting vehicle equipment and vice-versa.
(d) Check that the antenna and feeder are correctly adjusted.
(e) Do not install high-powered mobile communication system.

8. HEADLIGHT INSPECTION OR MAINTENANCE
(a) When the headlight dimmer switch assembly is set to HEAD, do not touch the discharge headlight's high-voltage socket area.
NOTE:
When performing inspection or maintenance, the discharge headlight precautions must be followed.





(b) When the headlights are illuminated, do not cover the headlights for 3 minutes or more.
NOTE:
As the headlight's outer lens is made of resin, the resulting heat created when covering the headlight for an extended period of time may deform the headlight.

9. FOR VEHICLES EQUIPPED WITH TRACTION CONTROL (TRAC) AND VEHICLE STABILITY CONTROL (VSC) SYSTEMS
(a) NOTICES FOR WHEN TESTING WITH 2-WHEEL DRUM TESTER




(1) When testing with a 2-wheel drum tester such as a speedometer tester, a combination speedometer and brake tester, or a chassis dynamometer, enter inspection mode, or switch to VSC OFF mode to turn TRAC and VSC operation off.
- If the vehicle is tested in normal mode on the drum tester, TRAC and VSC operation may cause the vehicle to jump out from the drum tester.
- When switching to VSC OFF mode, the VSC OFF switch must be held for 3 seconds or more with the vehicle stopped. TRAC and VSC operation must both be turned off before beginning testing.
- During VSC OFF mode, the combination meter's SLIP indicator light and VSC OFF indicator light illuminate.
- Secure the vehicle in place with chains for safety.

(b) Activating inspection mode (Not using the Techstream)
HINT:
- Perform steps "C" to "H" within 30 seconds.
- Perform steps "F" and "G" within 15 seconds each.
(1) Ensure that the engine switch is off and the engine is stopped (Step "A").
(2) Make sure that the shift lever is in P (Step "B").
(3) Start the engine (Step "C").
(4) Apply the parking brake by pressing the parking brake pedal (Step "D").
(5) Depress and release the brake pedal twice (Step "E").
(6) While holding the brake pedal down, release and apply the parking brake twice (Step "F").
(7) With the parking brake applied, depress and release the brake pedal twice (Step "G").




(8) Check if the SLIP indicator light comes on (Step "H").
- If the SLIP indicator light does not come on in step "H", repeat the steps from "A" to "H".
- Turning the engine switch off ends inspection mode.

(c) Activating inspection mode (Using the Techstream)
(1) Ensure that the engine switch is off and the engine is stopped (Step "A").
(2) Make sure that the shift lever is in P (Step "B").
(3) Connect the Techstream to the DLC3 (Step "C").
(4) Start the engine (Step "D").
(5) Turn the Techstream switch on (Step "E").
(6) Enter the following menus: Chassis / ABS/VSC/TRAC / Utility / Inspection Mode (Step "F").




(7) Check if the SLIP indicator light comes on (Step "G").
- If the SLIP indicator light does not come on in step "G", repeat the steps from "A" to "G".
- Turning the engine switch off ends inspection mode.

(d) NOTICES FOR VSC RELATED PROCEDURES
(1) For VSC related parts, adjustments are required after removal and installation. Therefore, perform removal and installation only when necessary.
(2) When performing VSC related procedures, be sure to strictly follow the preparation and completion procedures.
(3) When performing removal and installation or replacement of VSC related parts, first disconnect the cable from the negative (-) battery terminal.
10. FOR VEHICLES EQUIPPED WITH CATALYTIC CONVERTER
CAUTION:
If a large amount of unburned gasoline or gasoline vapors flow into the converter, it may cause converter overheating and create a fire hazard. To prevent this, observe the following precautions:

(a) Use only unleaded gasoline.
(b) Avoid idling the engine for more than 20 minutes.
(c) Avoid performing unnecessary spark tests.
(1) Perform a spark test only when absolutely necessary. Perform this test as rapidly as possible.
(2) While testing, never race the engine unless instructed.
(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.
11. INSPECTION AND ADJUSTMENT OF JOINT ANGLE DURING REMOVAL AND INSTALLATION OF PROPELLER SHAFT
(a) When performing operations which involve the removal and installation of the propeller shaft, always check the joint angle. Make adjustments if necessary Installation.
