2. Turn off the ignition and connect the tester to the 16-pin diagnostic connector under the instrument panel.
3. Install the strobe light.
4. Start the engine and let it idle.
5. Check that the idle speed is within the specified value (see section "Checking the idle speed").
6. Select the settings on the tester that correspond to the basic ignition timing setting.
7. Check the value of the basic ignition advance angle, which should be within the specified limits. Basic ignition advance angle:
- 2.0L engine - 5°±2° before TDC
- 2.4L engine - 7°±5° before TDC
- 2.7L engine - 12°±5° before TDC
8. If the basic ignition timing is not within the specified value, troubleshoot and check the fuel injection system components.
9. Press the reset button on the tester to disable the basic advance angle mode (Actuator Test item).
Warning: If you do not do this, the forced control mode of the device will remain for 27 minutes. Driving the car under these conditions may cause engine damage.
Note:
- Even under normal engine operation, the ignition timing angle changes within +5°.
- As the altitude increases, the ignition timing angle is automatically increased.
10. Disconnect the strobe light.
11. Turn off the ignition and disconnect the tester.
