If none of the functions can be used, check the diagnostic trouble codes, and after
carrying out any necessary repairs, repeat the operation. If an incorrect password is
input five times in a row, the immobilizer-ECU judges that an unauthorized
operation is being attempted. Start-prevention mode will be set, and engine
operation will stop and all special functions will be disabled. If the ignition switch
is turned to "ON" position and left in that position for approximately 16 minutes,
"Unauthorized operation, start- prevention mode" will be cancelled. KEY ID REGISTRATION All ignition keys can be registered with scan tool MB991958. Additional ignition
keys can be registered with or without scan tool MB991958. REGISTRATION WITH THE SCAN TOOL 1. Connect scan tool MB991958 to the data link connec
tor.
CAUTION: To prevent damage to scan tool MB991958, always
turn the ignition switch to "LOCK" (OFF) position
before connecting or disconnecting scan tool
MB991958.
NOTE:
Before registration, check that no DTC code is set. If a
DTC code is set, resolve the problem beforehand. Using the key ID register function will cause all key IDs
that have been previously registered in the immobilizer-
ECU to be erased. All ke
ys need to be re
gistered. Those
which have been registered before should be on hand
before using this function.
If registering more than one key, do not disconnect
scan tool MB991958 halfway through the registration
process. After registering key IDs, check that the engine can be
started using all of the keys that have been registered.
If the engine will not start, refer to IMMOBILIZER SYSTEM DIAGNOSIS
.

1. With the engine running (hydraulic operation), set the front wheels
straight ahead.
2. Slightly move the steering wheel in both directions, and measure the play
on the steering wheel circumference before the wheels start to move.
Limit: 30 mm (1.2 inch)
3. If the free play exceeds the limit, set the steering wheel straight ahead with
the engine stopped. Apply approximately 5 N (1.1 pound) to the steering
circumference and check the play.
Standard value (steering wheel play with engine stopped): 10 mm (0.4
inch) or less
Q: Does the play exceed the standard value?
YES: Remove the steering gear box (Refer to POWER STEERING
GEAR BOX AND LINKAGE
) and check the total pinion torque (Refer
to STEERING GEAR TOTAL PINION TORQUE CHECK
). Then go
to Step 3.
NO
: Go to Ste
p 3.

YES: Repeat from Step 1 .
NO: The procedure is complete.
INSPECTION PROCEDURE 2: DIFFICULT STEERING WHEEL OPERATION (INSUFFICIENT POWER ASSIST) DIAGNOSIS
STEP 1. Check the drive belt for damage.
Q: Is the drive belt damaged?
YES: Replace the drive belt. Then go to Step 9 .
NO: Go to Step 2.
STEP 2. Check the power steering oil pump drive belt tension.
Refer to 7. DRIVE BELTS (FOR GENERATOR, POWER STEERING OIL PUMP AND AIR CONDITIONING) (CHECK)
.
Q: Is the power steering oil pump drive belt tension within the standard
value?
YES: Go to Step 3.
NO: Adjust the tension. (Refer to 7. DRIVE BELTS (FOR
GENERATOR, POWER STEERING OIL PUMP AND AIR CONDITIONING) (CHECK)
). Then go to Step 9 .
STEP 3. Check the fluid level.
1. Park the vehicle on a flat, level surface, and then start the engine.
2. Turn the steering wheel several times to raise the temperature of the fluid
to approximately 50 - 60°C (122 - 140°F).
3. With the engine running, turn the wheel all the way to the left and right
several times.
4. Check the fluid in the oil reservoir for foaming or milkiness. Check the
difference of the fluid level when the engine is stopped, and while it is
running.
Q: Is the check result OK?

STEP 1. Check the fluid level.
1. Park the vehicle on a flat, level surface, and then start the engine.
2. Turn the steering wheel several times to raise the temperature of the fluid
to approximately 50 - 60°C (122 - 140°F).
3. With the engine running, turn the wheel all the way to the left and right
several times.
4. Check the fluid in the oil reservoir for foaming or milkiness. Check the
difference of the fluid level when the engine is stopped, and while it is
running.
Q: Is the check result OK?
YES: Go to Step 2.
NO: Bleed the air (Refer to POWER STEERING SYSTEM AIR
BLEEDING
). Then
go to Ste

NO: The procedure is complete.
INSPECTION PROCEDURE 9: VIBRATION DIAGNOSIS
STEP 1. Check the tires for out-of-balance.
Q: Is the check result OK?
YES: Go to Step 2.
NO: Balance the tires (Refer to WHEEL BALANCE ACCURACY
).
Then go to Step 4 .
STEP 2. Check the fluid level.
1. Park the vehicle on a flat, level surface, and then start the engine.
2. Turn the steering wheel several times to raise the temperature of the fluid
to approximately 50 - 60°C (122 - 140°F).
3. With the engine running, turn the wheel all the way to the left and right
several times.
4. Check the fluid in the oil reservoir for foaming or milkiness. Check the

NOTE: A slight vibration may be felt when the stationary steering
effort is made due to the condition of the road surface. To
check whether the vibration actually exists or not, test-drive
the vehicle on a dry concrete or asphalt surface. A very
slight amount of vibration is not a malfunction.

4. Check the fluid in the oil reservoir for foaming or milkiness. Check the
difference of the fluid level when the engine is stopped, and while it is running.
If the fluid contains air or has milky appearance, or the fluid level fluctuate by
5 mm (0.2 inch) or more, power steering system air bleeding should be done.

Perform air bleeding procedure as necessary after replacing the steering gear, oil
pump or the steering fluid lines.
1. Raise and support the front wheels.
2. Disconnect the ignition coil connectors (Refer to IGNITION COIL
).
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 IGNITION COIL
).
5. Start the engine and allow to idle.
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 the high and
low dipstick marks.
8. Confirm that there is very little change in the fluid level when the steering
wheel is turned left and right.
9. Confirm that the change in the fluid level is no more than 5 mm (0.2 inch)
when the en
gine is sto
pped.
CAUTION: Perform air bleeding only while cranking the
engine. Do not perform air bleeding while the
en
gine is runnin
g. If
you do so, air in the fluid will
be increased and air bleeding will become more
difficult. During air bleeding, refill the steering
fluid so that the level never falls below the lower
mark on the dipstick.
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 reduce
the life of the power steering components.
