Diagnostic Information and Procedures
Oil Pressure CheckS6RW0D1504001
WARNING!
To avoid the danger of being burned, do not
touch the exhaust system when the system is
hot. Any service on the exhaust system
should be performed when the system is
cool.

NOTE
Prior to checking oil pressure, check the
following.
• Oil level in oil pan
If oil level is low, add oil up to full level
mark (hole) (1) on oil level gauge referring
to “Engine Oil and Filter Change in Section
0B”.
• Oil quality
If oil is discolored or deteriorated, change
it. For particular oil to be used, refer to
“Engine Oil and Filter Change in Section
0B”.
• Oil leaks
If leak is found, repair it.

1) Disconnect oil pressure switch coupler (1).
2) Remove oil pressure switch (2) from cylinder block.3) Install special tools (oil pressure gauge) to vacated
threaded hole of oil pressure switch.
Special tool
(A): 09915–77310
(B): 09915–78211
4) Start engine and warm engine up to normal
operating temperature.
NOTE
Be sure to shift transaxle gear shift lever in
“Neutral”, set parking brake and block drive
wheels.

5) After warming up, raise engine speed to 4,000 r/min.
and measure oil pressure.
Oil pressure specification
More than 270 kPa (2.7 kgf/cm2, 39.8 psi) at 4,000
r/min. (rpm)
6) After checking oil pressure, stop engine and remove
oil pressure gauge and attachment.
7) Before reinstalling oil pressure switch (2), be sure to
wrap its screw threads with sealing tape (1) and
tighten switch to specified torque.
NOTE
If sealing tape edge is bulged out from screw
threads of switch, cut it off.

General Description
Rear Differential DescriptionS6RW0D3201001
The differential assembly uses a hypoid bevel pinion and gear.
The differential assembly is decisive in that the drive power is concentrated there. Therefore, use of genuine parts and
specified torque is compulsory. Further, because of sliding tooth meshing with high pressure between hypoid bevel
pinion and gear, it is mandatory to lubricate them by hypoid gear oil.
Coupling DescriptionS6RW0D3201002
Coupling is installed in the forward of Rear differential. The road situation and driving are judged with 4WD control
module based on information from sensor and each control module, and the distribution of driving force of the front
and rear wheel has been changed by controlling the current to coupling. Coupling air temperature sensor is installed in
coupling case and measures the temperature in coupling.
4WD system has three driving positions (2WD, 4WD-auto, 4WD-lock). The position corresponding to the running
situation can be selected by 2WD/4WD switch.

Malfunction Indicator Lamp (MIL) CheckS6RW0D5104003
Refer to the same item in “Malfunction Indicator Lamp (MIL) Check in Section 1A” for checking procedure.
Transmission Warning Light Check (Non-Euro-OBD model)S6RW0D5104053
1) Turn ignition switch ON.
2) Check that transmission warning light lights for about 2 – 4 sec. and then goes OFF.
If anything faulty is found, advance “Transmission Warning Light Circuit Check – Light Does Not Come “ON” at
Ignition Switch ON (Non-Euro-OBD Model)” or “Transmission Warning Light Circuit Check – Light Remains “ON”
at Ignition Switch ON (Non-Euro-OBD Model)”.
DTC TableS6RW0D5104004
NOTE
• There are two types of OBD system depending on the vehicle specification.For identification, refer
to “Precaution on On-Board Diagnostic (OBD) System in Section 1A”.
• For non-Euro-OBD model, some of DTC No. with (*) mark in the following table can not be detected
by TCM depending on vehicle specification and local regulation.
• With the CAN communication OBD generic scan tool, DTC No. with delta (U) mark in the following
table can not be read.
• A: Driving cycles when MIL lighting and storing DTC in TCM memory for Euro OBD model.
• B: Driving cycles when transmission warning light lighting and storing DTC in TCM memory for non-
Euro-OBD model.
• 1 driving cycle: MIL or transmission warning light lights up when DTC is detected during 1 driving
cycle.
• 2 driving cycles: MIL or transmission warning light lights up when the same DTC is detected also in
the next driving cycle after DTC is detected and stored temporarily in the first driving cycle.
• Driving cycle with (*): MIL or transmission warning light does not light up but TCM detects and
stores DTC.

Also check the following items at engine start, if possible.
• Malfunction indicator lamp ----- Operation “Malfunction Indicator Lamp (MIL) Check”
• Transmission warning light ----- Operation “Transmission Warning Light Check (Non-Euro-
OBD model)”
• Charge warning lamp ----- Operation “Generator Symptom Diagnosis in Section 1J”
• Engine oil pressure warning lamp ----- Operation “Oil Pressure Warning Light Symptom Diagnosis in
Section 9C”
• Engine coolant temp. meter ----- Operation “Engine Coolant Temperature (ECT) Meter
