ON-VEHICLE SERVICE

DRIVE BELT TENSION CHECK

M1111003100548

CAUTION

Check the drive belt tension after turning the 
crankshaft clockwise one turn or more.

1. Make sure that the indicator mark is within the 

area marked with A in the illustration.

2. If the mark is out of the area, replace the drive 

belt. (Refer to 

P.11C-17

).

NOTE: The drive belt tension check is not 
necessary as auto-tensioner is adopted.

AUTO-TENSIONER CHECK

M1111003000251

OPERATION CHECK

1. Turn OFF the engine from the idle state then 

check to see that the drive belt is not protruding 
from the pulley width of the auto-tensioner.

2. Remove the drive belt.(Refer to 

P.11C-17

).

3. Securely insert the spindle handle or ratchet 

handle with a 12.7 mm insertion angle into the jig 
hole of the auto tensioner. Turn the auto-tensioner 
to the left and right to check and see that there is 
no threading.

4. If there are any problems in the procedure 1 or 3, 

replace the auto-tensioner.(Refer to 

P.11C-36

).

5. Install the drive belt.(Refer to 

P.11C-17

).

FUNCTION CHECK

You can verify if the auto-tensioner is defective or not 
by checking the drive belt tension.
When using MUT-II
1. Check the drive belt tension. (Refer to 

P.11C-8

).

2. Measure the drive belt tension vibration frequency 

by the following procedures:

CAUTION

To prevent damage to MUT-II, always turn the 
ignition switch to the "LOCK" (OFF) position 
before connecting or disconnecting MUT-II.

(1) Connect special tool belt tension meter set 

(MB991668) to the MUT-II.

(2) Connect the MUT-II to the diagnosis 

connector.

(3) Turn the ignition switch to "ON" position, and 

select "BELT TENSION" on the menu screen.

CAUTION

•

The temperature of the surface of the belt 
should be as close to normal temperature as 
possible.

•

Do not allow any contaminants such as water 
or oil to get onto the microphone.

•

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.

•

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.

•

Do not take the measurement while the 
vehicle's engine is running.

(4) Hold special tool belt tension meter set 

(MB991668) to the middle of the drive belt 
between the pulleys (at the place indicated by 
arrow), approximately 10 

−

 20 mm away from 

the rear surface of the belt so that it is 
perpendicular to the belt (within an angle of 

±

 

15 degree).

(5) Gently tap the middle of the belt between the 

pulleys (the place indicated by the arrow) with 
your finger as shown in the illustration, and 
measure that the vibration frequency of the 
belt is within the standard value.

Standard value:

<A/C compressor type: MSC90CA> 113 

−

 145 

Hz

<A/C compressor type: MSC105CA> 120 

−

 154 

Hz

3. If not within the standard value, replace the 

auto-tensioner. (Refer to 

P.11C-36

).

When using V.C.I.
1. Check the drive belt tension. (Refer to 

P.11C-8

).

2. Measure the drive belt tension vibration frequency 

by the following procedures:

CAUTION

To prevent damage to special tool V.C.I. 
(MB991824), always turn the ignition switch to 
the "LOCK" (OFF) position before connecting or 
disconnecting special tool V.C.I. (MB991824).

(1) Connect special tool belt tension meter set 

(MB991668) to special tool V.C.I. (MB991824).

(2) Connect special tool MUT-III main harness B 

(MB991911) to special tool V.C.I. (MB991824).

(3) Connect special tool MUT-III main harness B 

(MB991911) to the diagnosis connector.

(4) Turn the ignition switch to "ON" position, and 

select "Belt Tension" on the menu screen.
