CAUTION
To prevent damage to scan tool MB991502, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991502.
1. Connect special tool MB991668 to the scan tool MB991502.
2. Connect scan tool MB991502 to the data link connector.
3. Turn the ignition switch to the "ON" and select scan tool
MB991502 "Belt Tension Measurement" from the menu
screen.
4. Hold special tool MB991668 (microphone) to the middle of
the drive belt between the pulleys (at the place indicated by
the arrow), about 10
−
20 mm (0.4
−
0.8 inch) away from the
rear surface of the belt and so that it is perpendicular to the
belt (within an angle of
±
15 degree angle).
CAUTION
•
The temperature of the surface of the belt should be as
close as possible to underhood temperature.
•
Do not let any contaminants such as water or oil 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.
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 check that the vibration frequency of the
belt is within the standard value.
