2. Connect scan tool MB991958 to the data link connector.
3. Turn the ignition switch to the "ON" position and select "Belt Tension
Measurement" from the special tool MB991824 screen menu.
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).
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 stan
dard value.
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.

2. Adjust the belt tension to the standard value by turning the adjusting bolt. The
tension will increase when turning the adjusting bolt clockwise, and decrease
when turning counterclockwise.
3. Tighten the lock nut to the specified torque.
Tightening torque: 49+/-9 N.m (36+/-7 ft-lb)
4. Tighten the adjusting bolt.
Tightening torque: 5.0+/-1.0 N.m (44+/-9 in-lb)
5. Check the belt deflection amount and tension, and readjust if necessary.
IGNITION TIMING CHECK
CAUTION: Check after turning the crankshaft one or more
rotations clockwise.

3. Set up a timing light.
4. Start the engine and run it at idle.
5. Check that the idle speed is approximately 680 r/min.
6. Select scan tool MB991958 actuator test "item number 17".
7. Check that basic ignition timing is within the standard value.
Standard value: 5° BTDC +/-3°
8. If the basic ignition timing is not within the standard value, check the
following items:
Diagnostic output Timing belt cover and crankshaft position sensor installation conditions Crankshaft sensing blade condition
9. Press the clear key on scan tool MB991958 (select forced drive stop mode),
and cancel the actuator test.
10. Check that the actual ignition timing is at the standard value.
Standard value: Approximately 10° BTDC
CURB IDLE SPEED CHECK Required Special Tool:
CAUTION: If the actuator test is not canceled, the forced
drive will continue for 27 minutes. Driving in this
state could lead to engine failure.
NOTE: Ignition timing fluctuates about+/-7° Before T op Dead
Center, even under normal operating condition.
NOTE: It is automatically further advanced by about 5° to 10°
Before Top Dead Center at higher altitudes.
