Crankshaft oil seals (front and rear)

Camshaft position sensor (PHASE)
OIL PRESSURE CHECK
WARNING:

Be careful not to get burn yourself, as engine oil may be hot.

Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove front engine undercover with power tool.
3. Disconnect harness connector at oil pressure switch, and
remove oil pressure switch using deep socket (commercial ser-
vice tool).
CAUTION:
Do not drop or shock oil pressure switch.

Remove the oil pressure switch using a 26 mm (1.02 in) box
wrench. (AWD models)
4. Install the oil pressure gauge (SST) and hose (SST).
5. Start the engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load.
NOTE:
When the engine oil temperature is low, the engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
Unit: [kPa (kg/cm2 , psi)]
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.

THE ALIGNMENT PROCESS
IMPORTANT:
Use only the alignment specifications listed in this Service Manual.

When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
–The alignment specifications programmed into your machine that operate these indicators may not be cor-
rect.
–This may result in an ERROR.

Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). DO NOT use this “Rolling Compensation”
method.
–Use the “Jacking Compensation Method”. After installing the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
–See Instructions in the alignment machine you're using for more information on this.
CAMBER INSPECTION

Measure camber of both right and left wheels with a suitable alignment gauge.

Adjust in accordance with the following procedures.

If outside the standard value, adjust with adjusting bolt in front
lower link.
NOTE:
After adjusting camber, be sure to check toe-in.
TOE-IN
If toe-in is not within the specification, adjust with adjusting bolt in
rear lower link.
CAUTION:
Be sure to adjust equally on RH and LH side with adjusting bolt.
If toe-in is not still within the specification, inspect and replace any
damaged or worn rear suspension parts.Standard value
Camber : Refer to RSU-18, "

SPECIFICATIONS (SDS)" .

ELECTRIC CONTROLLED COUPLING
Operation Principle
1. AWD control unit supplies command current to electric controlled coupling (AWD solenoid).
2. Control clutch is engaged by electromagnet and torque is detected in control clutch.
3. The cam operates in response to control clutch torque and applies pressure to main clutch.
4. Main clutch transmits torque to front wheels according to pressing power.

Transmission torque to front wheels is determined according
to command current.
AWD CONTROL UNIT

Controls distribution of drive power between rear-wheel drive
(0:100) and AWD (50:50) conditions according to signals from
sensors.

Self-diagnosis can be done with CONSULT-II.
