(4) Hold the special tool (MB991668) to the middle of
the belt between the pulleys (at the place indicated
by the arrow) about 10 - 20 mm away from the rear
surface and so that it is perpendicular to the belt
(within an angle of±15°).
(5) Gently tap the middle of the belt between the pulleys
(at the place indicated by the arrow) with your finger
as shown in the illustration, and check that the
vibration frequency of the belt is within the standard
value.
Standard value: 110 - 144 Hz
Caution
1) Check the vibration frequency of the belt when
the temperature of the surface of the belt is
as close as possible to normal temperature.
2) Do not let any contaminants such as water
or oil get onto the microphone.
3) If strong gusts of wind blow against the
microphone or if there are any loud sources
of noise nearby, the values measured by the
microphone may not correspond to actual
values.
4) If the microphone is touching the belt while
the measurement is being made, the values
measured by the microphone may not
correspond to actual values.
5) Do not take the measurement while the
vehicle’s engine is running.

Use the belt tension gauge and check that the belt tension
of the middle of the belt between pulleys
(at the place indicated by arrow) is within the standard
value.
Standard value: 245 - 412 N
2. If the value is outside the standard value, replace the
drive belt.Power steering

REMOVAL SERVICE POINTS
AA"DRIVE BELT REMOVAL
Due to the adoption of the Serpentine drive system with the
auto-tensioner, the following operation is required:
1. Insert the 12.7sq. spinner handle into the tool hole of
the auto-tensioner and rotate it counterclockwise until
the auto-tensioner reaches to the stopper.
2. Align hole A with hole B for fixing by inserting the L
shaped-hexagon wrench, then remove the drive belt.
Caution
When the drive belt is reused, use a chalk to indicate
an arrow of rotation direction on the back of the belt
so that it can be re-assembled in the same direction
as before.
AB"POWER STEERING OIL PUMP, BRACKET AND
OIL RESERVOIR ASSEMBLY / A/C COMPRESSOR
REMOVAL
Remove the power steering oil pump, bracket, oil reservoir
and A/C compressor with the hose attached from the bracket.
NOTE
Tie the removed oil pump and A/C compressor with a rope
and set aside where they cannot hinder the removal of the
engine assembly.
AC"ENGINE MOUNTING BRACKET AND STOPPER
ASSEMBLY REMOVAL
1. Support the engine with a garage jack.
2. Remove special tool (MZ203827).
(Tool used for removal of transmission assembly)
3. Hold the engine assembly with a chain block.
4. Support the engine oil pan with a garage jack via a block

NOTE
If the engine warning lamp illuminates because of a malfunction of the engine-ECU, communication between
MUT-IIand the engine-ECU is impossible. In this case, the diagnosis code cannot be read.
METHOD OF READING AND ERASING DIAGNOSIS
CODES
Refer to GROUP 00 - How to Use Troubleshooting/Inspection
Service Points.
INSPECTION USING MUT-IIDATA LIST AND ACTUATOR
TESTING
1. Carry out inspection by means of the data list and the
actuator test function. If there is an abnormality, check
and repair the chassis harnesses and components.
2. After repairing, re-check using the MUT-IIand check that
the abnormal input and output have returned to normal
as a result of the repairs.
3. Erase the diagnosis code memory.
4. Remove the MUT-II, and then start the engine again and
carry out a road test to confirm that the problem has
disappeared.
