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.

1. Before checks set the vehicle in the following condition:
Engine coolant temperature: 80 - 95°C (176 - 203°F) Lights and all accessories: OFF Transaxle: P range
2. Connect scan tool MB991958 to the data link connec
tor.
NOTE: Vehicles for Canada, the headlight, taillight, etc. remain
lit even when the lighting switch is in "OFF" position
but this is no problem for checks.

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.

3. Check the basic ignition timing.
Standard value: 5° BTDC+/-3°
4. Start the engine.
5. Run the engine at idle for 2 minutes.
6. Check the idle speed. Select item number 22 and take a reading of the idle
speed.
Curb idle speed: 680+/-100 r/min
7. If the idle speed is outside the standard value, refer to MULTIPORT FUEL

1. Before checks set the vehicle in the following condition:
Engine coolant temperature: 80 - 95°C (176 - 203°F) Lights and all accessories: OFF Transaxle: P range
NOTE: The idle speed is controlled automaticall
y by the idle air
control system.
NOTE: Vehicles for Canada, the headlight, taillight, etc. remain
lit even when the lighting switch is in "OFF" position
but this is no problem for checks.

3. Check that the basic ignition timing is within the standard value.
Standard value: 5° BTDC+/-3°
4. Start the engine and increase the engine speed to 2,500 r/min for 2 minutes.
5. Set the CO, HC tester.
6. Check the CO contents and the HC contents at idle.
Standard value:
CO contents: 0.5% or less
HC contents: 100 ppm or less
7. If the CO and HC contents do not remain inside the standard value, check the
following items:
Diagnostic output Closed-loop control (When the closed-loop control is carried out normally, the
output signal of the heated oxygen sensor changes between 0 - 400 mV and
600 - 1,000 mV at idle.) Fuel pressures Injector Ignition coil, spark plug EGR system and EGR valve leak Evaporative emission system Compression pressure
COMPRESSION PRESSURE CHECK Re

NOTE: Replace the catalytic converter when the CO and HC
contents do not remain inside the standard value, even
though the result of the inspection is normal for all items.
