ENGINE -On-vehicle ServiceENGINE -On-vehicle Service11A-9
IGNITION TIMING CHECK
1. Before inspection, set the vehicle to the pre-inspection
condition.
2. Turn the ignition switch to “LOCK” (OFF) position and
then connect the MUT-IIto the diagnosis connector.
3. Set up a timing light.
4. Start the engine and run at idle.
5. Check that engine idle speed is within the standard value.
Standard value: 850±100 r/min
6. Select No.17 of the MUT-IIActuator test.
7. Check that basic ignition timing is within the standard
value.
Standard value: 5_BTDC±3_
8. If the basic ignition timing is outside the standard value,
inspect the MPI system while referring to GROUP 13A
- Troubleshooting.
9. Press the MUT-IIclear key (Select a forced driving cancel
mode) to release the Actuator test.
Caution
If the test is not cancelled, a forced driving will
continue for 27 minutes. Driving under this condition
may damage the engine.
10. Check that ignition timing is at the standard value.
Standard value: approximately 5_BTDC
NOTE
(1) Ignition timing is variable within about±7, even under
normal operating.
(2) And it is automatically further advanced by
approximately 5_from standard value at higher
altitudes.
11. Remove the timing light.
12. Turn the ignition switch to “LOCK” (OFF) position and
then remove the MUT-II.
IDLE SPEED CHECK
1. Before inspection, set the vehicle to the pre-inspection
condition.
2. Turn the ignition switch to “LOCK” (OFF) position, and
then connect the MUT-IIto the diagnosis connector.
3. Set the timing light.
4. Check that the basic ignition timing is within the standard
value.

ENGINE -On-vehicle ServiceENGINE -On-vehicle Service11A-10
Standard value: 5_BTDC±3_
5. Run the engine at idle for 2 minutes.
6. Check the idle speed. Select item No. 22 and take a
reading of the idle speed.
Curb idle speed: 850±100 r/min
NOTE
The idle speed is controlled automatically by the idle speed
control (ISC) system.
7. If the idle speed is outside the standard value, check
the MPI components by referring to GROUP 13A -
Troubleshooting.
8. Remove the timing light.
9. Turn the ignition switch to the “LOCK” (OFF) position
and then remove the MUT-II.
IDLE MIXTURE CHECK
1. Before inspection, set the vehicle to the pre-inspection
condition.
2. Turn the ignition switch to the “LOCK” (OFF) position,
and then connect the MUT-IIto the diagnosis connector.
3. Set the timing light.
4. Check that the basic ignition timing is within the standard
value.
Standard value: 5_BTDC±3_
5. Run the engine at 2,500 r/min for 2 minutes.
6. Set the CO, HC tester.
7. Check the CO contents and the HC contents at idle.
Standard value
CO contents: 0.1% or less
HC contents: 100 ppm or less
8. If there is a deviation from the standard value, check the
following items:
DDiagnosis output
DClosed-loop control (When the closed-loop control
is normal, the output signal of the oxygen sensor
changes between 0 - 400 mV and 600 - 1,000 mV
at idle.)
DFuel pressure
DInjector
DIgnition coil, spark plug cable, spark plug
DEvaporative emission control system
DCompression pressure
NOTE
Replace the three way catalyst when the CO and HC
contents are not within the standard value, even though
the result of the inspection is normal on all items.
9. Remove the timing light.

REMOVAL AND INSTALLATION
Caution
1. If the vehicle is equipped with the Brembo disc brake, during maintenance, take care not to
contact the parts or tools to the caliper because the paint of caliper will be scratched.
2. Tightening sections indicated in the mark (*) should be finally tightened with engine weight
applied on the body after lightly tightening.

3. Confirm that the tensioner B centre and bolt centre are
positioned as shown in the illustration.
4. Apply tension on the timing belt by lifting tensioner B
in the direction of the arrow with a finger, and tension
the tension side until it is “tight”. Fix tensioner B in this
state by tightening the bolt.
NOTE
Make sure that the tensioner B shaft does not rotate
when tightening the bolt. If the shaft rotates, the timing
belt becomes too tense.
5. Connect the special tool (MB991704) to MUT-IIand the
battery.
6. Connect the special tool (MB991668) to MUT-II.
7. Rotate the crankshaft clockwise two turns, and align each
timing mark.
8. Select “Belt Tension Measurement” from the MUT-IImenu
screen.
9. Separate the special tool (MB991668) 10 to 20 mm from
the centre back between the sprockets (shown with an
arrow), and hold so that it is vertical (inclination within
±15_) in respect to the belt.
10. Lightly tap the section shown with an arrow with fingers,
and measure the belt vibration frequency. If the results
are deviated from the standard value, loosen the bolt,
tension the belt again, and then measure the vibration
frequency again. Repeat this step until the standard value
is attained. Tighten the bolt when the standard value
is attained.

14. Using the special tool, rotate the tensioner pulley in the
counterclockwise direction to tense the timing belt, and
then fix by temporarily tightening the tensioner fixing bolt.
NOTE
Remove the deflection of the timing belt between the
intake side and exhaust side camshafts.
15. Rotate the crankshaft in the clockwise direction, and set
the timing mark at the No. 1 cylinder compression top
dead centre.
16. Set the special tool, and screw it in until the wire inserted
when the auto tensioner was installed slightly moves.
17. Loosen the tensioner pulley fixing bolt.
Caution
The timing belt will loosen at this time due to the
rotation of the intake and exhaust camshafts, so make
sure that the timing belt does not deviate.
18. Rotate the special tool and torque wrench in the
counterclockwise direction to remove the timing belt
deflection.
19. From that state, return to the position where the torque
wrench scale reads 3.5 N•m, and then tighten the fixing
bolt.
20. Remove the special tool installed in step 16.
21. Rotate the crankshaft two rotations in the clockwise
direction, and let stand for approx. 15 minutes.
22. Confirm whether the wire inserted when the auto tensioner
was installed can be pulled out easily. If it can be removed
easily, the belt tension is appropriate, so remove the wire.
If the auto tensioner rod’s protrusion amount is at the
standard value, the tension is appropriate.
Standard value: 3.8 - 4.5 mm
23. If the wire cannot be pulled out easily, repeat steps 16
to 21, and tense the belt to the appropriate tension.
Caution
When the crankshaft bolt has been rotated in the
counterclockwise direction, always check the crank-
shaft bolt’s tightening torque. If loosen, re-tighten.
