FUNCTION CHECK

You can verify if the auto-tensioner is defective or not
by checking the drive belt tension.

When using the M.U.T.-II

1. Check the drive belt tension. (Refer to

P.11A-7

2. Measure the drive belt tension vibration frequency

by the following procedures:

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 corre-
spond to actual values.

• Do not take the measurement while the vehi-

cle's engine is running.
