INTRODUCTION: REPAIR INSTRUCTION: PRECAUTION - Continued
3. ELECTRONIC CONTROL
(a) REMOVAL AND INSTALLATION OF BATTERY TERMINAL
NOTICE:
After disconnecting the negative (-) terminal, it is necessary to perform the initialization of certain systems.
(b) REMOVAL AND INSTALLATION OF BATTERY CABLE
(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 ignition 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.
(c) 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, 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 VEHICLE STABILITY CONTROL (VSC) SYSTEM
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 Inspection Mode and stop the TRAC and VSC systems.
Enter Inspection Mode to disable TRAC and VSC control when using a chassis dynamometer.
HINT
* The vehicle may move unexpectedly out of the dynamometer because of TRAC and VSC operations.
* Pressing the VSC OFF switch does not disable TRAC and VSC operations completely.
NOTICE:
* Secure the vehicle with a lock chain for safety.
* When performing procedures related to VSC OFF switch operation, make sure that the mode is VSC OFF mode.
(a) Activating Inspection Mode (When Using the Techstream)
(1) Ensure that the ignition switch is off and the engine is stopped.
(2) Make sure that the shift lever is in P.
(3) Connect the Techstream to the DLC3.
(4) Start the engine.
(5) Turn the Techstream on.
(6) Enter the following menus: Chassis / ABS/VSC/TRAC / Utility / Inspection Mode.
(7) Check that the SLIP indicator, TRAC OFF indicator and VSC OFF indicator lights will come on.
HINT
If the SLIP indicator, TRAC OFF indicator or VSC OFF indicator light does not come on, repeat the steps.
(8) Turn the ignition switch off.
HINT
Turning the ignition switch off ends Inspection Mode.
(b) Activating Inspection Mode (When not Using the Techstream)
HINT
Perform steps from "D" to "H" within 30 seconds.
(1) Ensure that the ignition 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 parking brake by depressing the parking brake pedal (Step "D").
(5) Depress and release the brake pedal twice (Step "E").
(6) Depress and hold the brake pedal down, then release and apply parking brake twice (Step "F").
(7) With parking brake applied, depress and release the brake pedal twice (Step "G").
(8) Check if the SLIP indicator, TRAC OFF indicator and VSC OFF indicator lights will come on (Step "H").
HINT
If the SLIP indicator, TRAC OFF indicator or VSC OFF indicator light does not come on in step "H", repeat the steps from "A" to "H".
(9) Turn the ignition switch off.
HINT
Turning the ignition 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 over heating and create 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 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.
