Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.

Information necessary to service the system safely is included in SUPPLEMENTAL RESTRAINT SYSTEM and SEAT BELTS .

When replacing transfer assembly or transfer control unit, check the 4WD shift indicator lamp as follows.

1. Turn ignition switch "ON".
2. Check 4WD shift indicator lamp is turned ON for approx. 1 second.

1. If OK, the position between transfer assembly and transfer control unit is correct.
2. If NG, the position is different between transfer assembly and transfer control unit. Adjust the position between transfer assembly and transfer control unit. Refer to «METHOD FOR POSITION ADJUSTMENT»(ref-233277-S18829732382006052500000) .

Service Notice

1. After overhaul refill the transfer with new transfer fluid.
2. Check the fluid level or replace the fluid only with the vehicle parked on level ground.
3. During removal or installation, keep inside of transfer clear of dust or dirt.
4. Disassembly should be done in a clean work area.
5. Before proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the internal parts from becoming contaminated by dirt or other foreign matter.
6. Check for the correct installation status prior to removal or disassembly. If matchmarks are required, be certain they do not interfere with the function of the parts when applied.
7. All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or reassembly.
8. Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them with new ones if necessary.
9. Gaskets, seals and O-rings should replaced any time the transfer is disassembled.
10. In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tightening sequence is specified, use it.
11. Observe the specified torque when assembling.
12. Clean and flush the parts sufficiently and blow-dry them.
13. Be careful not to damage sliding surfaces and mating surfaces.
14. Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere with the operation of the transfer.

FILLING

Refer to CHANGING TRANSFER FLUID .

WAIT DETECTION SWITCH

1. The wait detection switch operates when there is "circulating" torque produced in the propeller shaft (L --> H) or when there is a phase difference between 2-4 sleeve and clutch drum (H --> L). After the release of the "circulating" torque, the wait detection switch helps provide the 4WD lock gear (clutch drum) shifts. A difference may occur between the operation of the 4WD shift switch and actual drive mode. At this point, the wait detection switch senses an actual drive mode.
2. The wait detection switch operates as follows.

1. 4WD lock gear (clutch drum) locked: ON
2. 4WD lock gear (clutch drum) released: OFF

1. The wait detection switch senses an actual drive mode and the 4WD shift indicator lamp indicates the vehicle drive mode.

NEUTRAL-4LO SWITCH

The neutral-4LO switch detects that transfer gear is in neutral or 4LO (or shifting from neutral to 4LO) condition by L-H shift fork position.

ATP SWITCH

It detects that transfer gear is under neutral condition by L-H shift fork position.

Note. Transfer gear may be under neutral condition in 4H-4LO.

2-4 WD SHIFT SOLENOID VALVE

The 2-4 WD shift solenoid valve operates to apply oil pressure to the wet-multiplate clutch, depending on the drive mode. The driving force is transmitted to the front wheels through the clutch so the vehicle is set in the 4WD mode. Setting the vehicle in the 2WD mode requires no pressure buildup. In other words, pressure force applied to the wet-multiplate clutch becomes zero.

CLUTCH PRESSURE SOLENOID VALVE

The clutch pressure solenoid valve distributes each of torque (front and rear) with AUTO mode.

LINE PRESSURE SWITCH

1. With the transfer system design, control of the oil pressure provides the transmission of drive torque to the front wheels. The main pressure to control the oil pressure is referred to as the line pressure.
2. The line pressure switch determines whether or not adequate line pressure has built up under different operating conditions.
3. The line pressure switch turns ON when line pressure is produced.
4. The line pressure switch senses line pressure abnormalities and turns the 4WD warning lamp ON.

CLUTCH PRESSURE SWITCH

1. The clutch pressure switch determines whether or not adequate clutch pressure has built up under different operating conditions.
2. The clutch pressure switch turns ON when clutch pressure is produced.
3. The clutch pressure switch senses clutch pressure abnormalities and turns the 4WD warning lamp ON.

The transfer temperature sensor detects the transfer fluid temperature and sends a signal to the transfer control unit.

1. Transfer control unit controls transfer control device by input signals of each sensor and each switch.
2. Self-diagnosis can be done.

The transfer control device changes the state of transfer assembly between 2WD, AUTO, 4H --> 4LO with the 2WD, AUTO, 4H and 4LO signals of 4WD shift switch.

Note. To shift between 4H <==> 4LO, stop the vehicle, depress the brake pedal and shift the transmission selector to the "N" position. Depress and turn the 4WD shift switch. The shift switch will not shift to the desired mode if the transmission is not in "N" or the vehicle is moving. The 4LO indicator lamp will be lit when the 4LO is engaged. Actuator motor and actuator position switch are integrated.

4WD Shift Switch

Able to select from 2WD, AUTO, 4H or 4LO.

4WD Shift Indicator Lamp

1. Displays driving conditions selected by 4WD shift switch with 2WD, AUTO and 4H indicators while engine is running. (When 4WD warning lamp is turned on, all 4WD shift indicator lamps are turned off.)
2. Turns ON for approximately 1 second when ignition switch is turned ON, for purpose of lamp check.

4LO Indicator Lamp

1. Displays 4LO condition while engine is running. 4LO indicator lamp flashes if transfer gear does not shift completely under 2WD, AUTO, 4H <==> 4LO. (When 4WD warning lamp is turned on, 4LO indicator lamp is turned off.)
2. Turns ON for approximately 1 second when ignition switch is turned ON, for purpose of lamp check.

4WD WARNING LAMP

Turns ON or FLASH when there is a malfunction in 4WD system.

Also turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF for approximately 1 second after the engine starts if system is normal.

4WD Warning Lamp Indication

4WD WARNING LAMP INDICATION CONDITION

ATP WARNING LAMP

Even if A/T selector lever is in "P" position, vehicle may move because A/T parking mechanism does not operate when transfer is under neutral condition. ATP warning lamp is turned on so as to indicate this condition to the driver.
