5) Start the engine.
NOTE:
Make sure the select lever is placed in “P” position
before starting.
6) Using the select lever, turn the “P” position
switch and the “N” position switch to ON.
7) Depress the brake pedal to turn brake switch
ON.
8) Keep the engine speed in 2,500 — 3,000 rpm
range for 40 seconds.
9) Shift the select lever in the “D” range and drive
the vehicle at 5 to 10 km/h (3 to 6 MPH).
NOTE:
•For AWD model, release the parking brake.
•The speed difference between front and rear
wheels may light the ABS warning light, but this in-
dicates no malfunctions. When engine control diag-
nosis is finished, perform the ABS memory
clearance procedure of self-diagnosis system.
10) Using the general scan tool, check DTC and
record the result(s).
NOTE:
•For detailed operation procedure, refer to the
general scan tool operation manual.
•For details concerning DTC, refer to “List of Diag-
nostic Trouble Code (DTC)”.

6. Engine Oil Pressure
A: INSPECTION
1) Remove the oil pressure switch from cylinder
block. Pressure Switch.>
2) Connect the oil pressure gauge hose to cylinder
block.
3) Connect the ground cable to the battery.
4) Start the engine, and measure the oil pressure.
OIL PRESSURE (at oil temperature of 80°C
(176°F)):
Standard:
135 kPa (1.4 kgf/cm2, 20 psi) or more (at
600 rpm)
500 kPa (5.1 kgf/cm2, 73 psi) or more (at
5,000 rpm)
CAUTION:
•If the oil pressure is out of specification,
check oil pump, oil filter and lubrication line.
Diagnostics Table.>
•If the oil pressure warning light is turned ON
and oil pressure is in specification, replace the
oil pressure switch. SPECTION, General Diagnostics Table.>
5) After measuring the oil pressure, install the oil
pressure switch. LATION, Oil Pressure Switch.>

Brake Line
PERIODIC MAINTENANCE SERVICES
13.Brake Line
A: INSPECTION
1. BRAKE LINE
1) Check for scratches, swelling, corrosion, traces
of fluid leakage on the brake hoses or pipe joints.
2) Check the possibility of adjacent parts interfering
with brake pipes/hoses during driving, and loose
connections/clamps.
3) Check any trace of fluid leakage, scratches, etc.
on master cylinder, wheel cylinder and pressure
control valve.
NOTE:
•When the brake fluid level in the reservoir tank is
lower than specified limit, the brake warning light
on the combination meter will come on.
•Visually check the brake hose for damage. (Use
a mirror where it is difficult to see)
2. SERVICE BRAKE
1) Check the free play of brake pedal with pulling
up the force of less than 10 N (1 kgf, 2 lb).
Brake pedal free play (Pulling up direction of
pedal)
0.5 — 2.0 mm (0.02 — 0.08 in)
2) If the free play is out of specifications above, ad-
just the brake pedal as follows.
(1) Make sure the engine is off. (No vacuum is
applied to brake booster.)
(2) There should be play between brake boost-
er clevis and pin at brake pedal installing por-
tion. [Pulling up the brake pedal pad with a force
of less than 10 N (1 kgf, 2 lb) to a stroke of 0.5
to 2.0 mm (0.02 to 0.08 in).]
(3) If there is no free play between clevis pin
and clevis, turn brake switch adjusting nut until
the clearance between stopper and screw of
brake switch becomes 0.8 mm (0.031 in).
(1) Front brake hose
(2) Front brake pipe
(1) Rear brake pipe
(2) Rear brake hose

Check the airbag system in accordance with the result of the self-diagnosis. agnostic Procedure.>
1) Make sure that airbag connectors are connected. If not, properly connect. When the ignition switch is
turned ON with the connector(s) disconnected, the airbag warning light blinks to identify the fault.
2) Connect the Subaru Select Monitor to data link connector. Turn the ignition switch to ON, and Subaru Se-
lect Monitor switch to ON.
3) Read the Diagnostic Trouble Code (DTC) using Subaru Select Monitor. AGNOSTIC TROUBLE CODE (DTC), OPERATION, Subaru Select Monitor.>
