Ignition Timing: Testing and Inspection

IGNITION TIMING CHECK
1. Before inspection, set the vehicle in the following condition:
- Engine coolant temperature: 80 - 95°C (176 - 203°F)
- Lights, electric cooling fan and all accessories: OFF
- Transaxle: Neutral (P range on vehicles with A/T)
2. Connect the scan tool to the data link connector.
3. Set up a timing light.
4. Start the engine and run at idle.
5. Check that the idle speed is at approximately 700 r/min.
6. Select the "item No.17" of the actuator test on the scan tool.
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, check the MFI components by referring to Powertrain Management; Testing and Inspection.
9. Press the clear key of the scan tool (select force-activating cancel mode), and cancel the actuator test.

NOTE: If it is not canceled, 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: Approximately 5° BTDC

NOTE:
1. Ignition timing is variable within about ± 7°, even under normal operating.
2. The timing is automatically further advanced by approximately 5° from 5° BTDC at higher altitude.
