PRECAUTION (Continued)

3. ELECTRONIC CONTROL





(a) REMOVAL AND INSTALLATION OF BATTERY TERMINAL

NOTE: Certain systems need to be initialized after reconnecting the cable to the negative (-) battery terminal.

(1) Before performing electronic 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 dimmer 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 erased 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 engine 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, 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, working 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 inlet system parts, this may damage the engine.
(b) When removing and installing inlet system parts, cover the openings of the removed parts and engine openings. Use gummed tape or other suitable materials.
(c) When installing inlet system parts, check that no metal particles have entered the engine or the installed parts.





6. HANDLING OF HOSE CLAMPS
(a) Before removing the 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, you may want 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 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 ECU and sensors 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 any high-powered mobile communication system.

8. FOR VEHICLES EQUIPPED WITH TRACTION CONTROL (TRAC) AND VEHICLE STABILITY CONTROL (VSC) SYSTEMS
When testing with a 2-wheel drum tester such as a speedometer tester, a combination tester for the speedometer and brake, a chassis dynamometer, or when jacking up the front wheels and turning the wheels, perform the following procedure to enter the inspection mode and stop the TRAC and VSC systems.
(a) Activating inspection mode (Not using Techstream)
HINT:
- Perform procedures "D" to "H" within 30 seconds.
- Perform procedures "F" and "G" within 15 seconds each.
(1) Ensure that the engine switch is off and the engine is stopped (Procedure "A").
(2) Make sure that the shift lever is in the P position (Procedure "B").
(3) Start the engine (Procedure "C").
(4) Apply the parking brake by depressing the parking brake pedal (Procedure "D").
(5) Depress and release the brake pedal twice (Procedure "E").
(6) While holding the brake pedal down, release and apply the parking brake twice (Procedure "F").
(7) With the parking brake applied, depress and release the brake pedal twice (Procedure "G").




(8) Check that the "VSC TEST MODE" message appears on the multi-information display and SLIP indicator light come on (Procedure "H").
- If the "VSC TEST MODE" message appears on the multi-information display and SLIP indicator light do not come on in procedure "H", repeat the procedures from "A" to "H".
- Turning the engine switch off ends inspection mode.

(b) Activating inspection mode (Using Techstream)
(1) Ensure that the engine switch is off and the engine is stopped (Procedure "A").
(2) Make sure that the shift lever is in the P position (Procedure "B").
(3) Connect Techstream to the DLC3 (Procedure "C").
(4) Start the engine (Procedure "D").
(5) Turn the Techstream main switch on (Procedure "E").
(6) On the tester display, select the inspection mode (Procedure "F").




(7) Check that the "VSC TEST MODE" message appears on the multi-information display and SLIP indicator light come on (Procedure "G").
- If the "VSC TEST MODE" message appears on the multi-information display and SLIP indicator light do not come on in procedure "G", repeat the procedures from "A" to "G".
- Turning the engine switch off ends inspection mode.

9. FOR VEHICLES EQUIPPED WITH CATALYTIC CONVERTER
CAUTION:
If a large amount of unburned gasoline or gasoline vapors flow into the converter, it may cause 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 jump tests.
(1) Perform a spark jump test only when absolutely necessary. Perform this test as rapidly as possible.
(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.
