POWER STEERING37-14
CAUTION
Perform air bleeding only while cranking the
engine. If air bleeding is performed while the
engine is running, air could enter the fluid.
During air bleeding, refill the steering fluid
supply so that the level never falls below the
"MIN" mark on the oil reservoir.
3. Turn the steering wheel all the way to the left and
right five or six times while using the starter motor
to crank the engine intermittently several times
(for 15 to 20 seconds).
4. Connect the ignition coil connectors (Refer to
GROUP 16, Ignition Coil P.16-38 or P.16-39).
5. Start the engine (idling).
6. Turn the steering wheel to the left and right until
there are no air bubbles in the oil reservoir.
7. Confirm that the fluid is not milky, and that the
level is between "MAX" and "MIN" marks.
8. Confirm that there is very little change in the fluid
level when the steering wheel is turned left and
right.
CAUTION
If the fluid level rises suddenly after the engine is
stopped, the air has not been completely bled. If
air bleeding is not complete, there will be
abnormal noises from the pump and the
flow-control valve, and this condition could
cause reduce the life of the power steering
components.
9. Confirm that the change in the fluid level is no
more than 5 mm when the engine is stopped and
when it is running.
10.If the change of the fluid level is 5 mm or more,
the air has not been completely bled from the
system. The air bleeding procedure must be
repeated.
OIL PUMP PRESSURE TESTM1372002300315
1. Disconnect the pressure hose from the oil pump,
and then connect the following special tools.
•MB990662: Power Steering Oil Pressure Gauge
•MB991548: Power Steering Oil Pressure Gauge
Adapter (pump side)
•MB991549: Power Steering Oil Pressure Gauge
Adapter (hose side)
2. Bleed air, then turn the steering wheel several
times while the vehicle is not moving so that the
temperature of the fluid rises to approximately 50
− 60°C.
3. Start the engine and idle it at 1000 ± 100 r/min.
CAUTION
The pressure gauge shut-off valve must not
remain closed for more than 10 seconds.
4. Fully close the shut-off valve of the pressure
gauge and measure the oil pump relief pressure
to confirm that it is within the standard value
range. Open it again immediately after checking
the pressure.
Standard value: 8.8 − 9.5 MPa
5. If it is not within the standard value, replace the oil
pump.
6. Check whether or not the hydraulic pressure is
the standard value when no-load conditions are
created by fully opening the shut-off valve of the
pressure gauge.
Standard value: 0.2 − 0.7 MPa

7. If it is not within the standard value, the probable
cause is a malfunction of the oil line or steering
gear, so check these parts and repair as
necessary.
8. Turn the steering wheel all the way to the left or
right; then check whether or not the retention
hydraulic pressure is the standard value.
Standard value: 8.8 − 9.5 MPa
9. If not the standard value, overhaul the steering
gear. Remeasure fluid pressure.
10. Remove the special tools, and then tighten the
pressure hose to the specified torque.
Tightening torque: 57 ± 7 N⋅m
11. Bleed the system (Refer to P.37-13).

times while the vehicle is not moving so that the
temperature of the fluid rises to approximately 50

3. The engine should be idling.
4. Disconnect the connector for the oil pressure
switch, and place an ohmmeter at the switch.
5. Gradually close the shut-off valve of the pressure
gauge and increase the hydraulic pressure, then
check whether or not the hydraulic pressure that
activates the switch is the standard value.
Standard value: 1.5 − 2.0 MPa
6. Gradually open the shut-off valve and reduce the
hydraulic pressure; then check whether or not the
hydraulic pressure that deactivates the switch is
the standard value.
Standard value: 0.7 − 2.0 MPa
7. Remove the special tools, and then tighten the
pressure hose to the specified torque.
Tightening torque: 57 ± 7 N⋅m
8. Bleed the system (Refer to P.37-13).
TIE ROD END BALL JOINT DUST COVER
CHECK
M1372008600262
1. Press the dust cover with your finger to check
whether the dust cover is cracked or damaged.
2. If the dust cover is cracked or damaged, replace
the tie rod end.
NOTE: If the dust cover is cracked or damaged,
the ball joint could be damaged.
STEERING COLUMN SHAFT ASSEMBLY
SHOCK ABSORBING MECHANISM
CHECK
M1372013500090
If a collision accident occurs or severe impact is
applied on the steering wheel, the collision energy
absorbing mechanism may have operated. Once the
mechanism has operated, it will be inoperative even
it has suffered no apparent damage. Determine if the
steering column shaft can be reused by the following
procedure. If the collision energy absorbing
mechanism has already operated, replace the
steering column shaft assembly.
If any excessive radial free play on the steering
wheel is found with the tilt lever in the lock position,
always check the steering shaft assembly.

DIAGNOSIS PROCEDURE
STEP 1. Check for presence of other key near the
key in the ignition.
Q: Is there any other key near the key in the ignition?
YES :
Move the other key well away from key
being used. Retest the system.
NO : Go to Step 2.
STEP 2. Check that the engine start using the
spare ignition key which encrypted code has
been registered.
Q: Does the engine start using the spare ignition key
for which the encrypted code has been registered?
YES :
Replace the ignition key that does not work.
Then register the password (secret code)
and encrypted code P.54A-20. Retest the
system.
NO : Go to Step 3.
STEP 3. Check whether the diagnosis code is
reset.
Q: Which diagnosis code is set, code No.11 or 12 the
encrypted code has been registered?
Code No.12 is set :
Refer toP.54A-11.
Code No.11 is set : Go to Step 4.
STEP 4. Connector check: Immobilizer-ECU
connector C-202-1.
Q: Are immobilizer-ECU connector C-202-1 in good
condition?
YES :
Replace immobilizer-ECU and Then
register the password (secret cod) and
encrypted code P.54A-20. Retest the
system.
NO : Repair or replace the damage
component(s).
Code No.12: Encrypted Codes are Not identical or not Registered
DIAGNOSIS CODE SET CONDITION
The encrypted code sent by the transponder is not
the same encrypted code which is registered in the
immobilizer-ECU.
NOTE: Diagnosis code No.12 is always set together
with MPI system diagnosis code No.P0513.
TROUBLESHOOTING HINTS
•The encrypted code in the ignition key has not
been properly registered.•Malfunction of immobilizer-ECU.
DIAGNOSIS PROCEDURE
Was the encrypted code registered?
YES :
Replace the immobilizer-ECU and then
re-register the encrypted code (Refer to
P.54A-20).
NO : Register the encrypted code (Refer to
P.54A-20).

TROUBLESHOOTING HINTS
•Malfunction of the immobilizer-ECU.
•Malfunction of the engine-ECU or
engine-A/T-ECU .
•The wiring harness or connectors may have
loose, corroded, or damaged terminals, or
terminals pushed back in the connector.
DIAGNOSIS PROCEDURE
STEP 1. Check if MUT-II/III can communicate with
the MPI system and if an MPI system diagnosis
code other than P0513 is set.
Q: Can MUT-II/III communicate with the MPI system?
Is an MPI system diagnosis code other than P0513
set?
YES :
Go to Step 2.
NO : Refer to GROUP 13A, MPI Diagnosis
P.13A-15, GROUP 13B, MPI Diagnosis
P.13B-15.
STEP 2. Voltage measurement at
immobilizer-ECU connector C-202-1.
(1) Disconnect immobilizer-ECU connector C-202-1.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 1 and
earth.
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 5.
NO : Go to Step 3.
STEP 3. Connector check: Immobilizer-ECU
connector C-202-1 and engine control relay
connector B-16X
Q: Are immobilizer-ECU connector C-202-1 and
engine control relay connector B-16X in good
condition?
YES :
