Connect the scan tool (MUT-11) to the diagnosis connector. Turn the ignition switch to “ON” and select “Belt Tension Measurement” on the menu screen. Hold the microphone to the middle of the drive belt between the pulleys (at the place indicated by an arrow) about 10 – 20 mm (0.39 – 0.79 in.) away from the rear surface of the belt and so that it is perpendicular to the belt (within an angle of k15”). Lightly tap the middle of the belt between the pulleys (the place indicated by the arrow) with your finger as shown in the illustration. Check that the vibration frequency of the belt is within the standard value. Caution 1. The temperature of the surface of the belt should be as close as possible to normal temperature. 2. Do not allow any contaminant such as water or oil to get onto the microphone. 3. If strong gusts of wind blow against the microphone or if there is any source of loud noise nearby, the values measured by the microphone may not correspond to actual values. 4. If the microphone is touching the belt during the measurement, the values measured by the microphone may not correspond to actual values. 5. Do not take the measurement while the vehicle’s engine is running. Use a belt tension gauge to check that the belt tension is within the standard value range.IGNITION TIMING CHECK 111001 701 50 Before inspection, set the vehicle in the following condition: 0 Engine coolant temperature: 80 – 95°C (1 76 – 203″ F) 0 Lights, electric cooling fan and all accessories: OFF 0 Transaxle: Neutral (P range on vehicles with A/T) Connect the scan tool to the data link connector. Set up a timing light. Start the engine and run at idle. Check that the idle speed is at approx. 700 rlmin. Select the ‘item No.17′ of the actuator test on the scan tool. Check that basic ignition timing is within the standard value. Standard value: 5″ BTDC k 3″ If the basic ignition timing is outside the standard value, check the MFI components by referring to GROUP 13A – Troubleshooting. Press the clear key of the scan tool (select force-activating cancel mode), and cancel the actuator test. NOTE If it is not cancelled, force-activation continues for 27 minutes. Do not drive the vehicle in this condition, or the engine could be damaged. 10. Check the actual ignition timing is at the standard value. Standard value: Approx. 5″ BTDC NOTE 1. Ignition timing is variable within about +7″, even under normal operating. 2. The timing is automatically further advanced by approx. 5″ from 5″BTDC at higher altitude.
