2. Turn off the ignition and connect the tester to the 16-pin diagnostic connector under the instrument panel.
3. Install the stroboscope.
4. Start the engine and let it idle.
5. Check that the idle speed corresponds to the nominal value (see section "Checking the idle speed").
6. Select settings on the tester that match the base ignition timing setting.
7. Check the value of the basic ignition timing, which must be within the specified limits. Basic ignition timing:
- Engine 2.0 l - 5°± 2°to TDC
- Engine 2.4 l - 7°± 5°to TDC
- Engine 2.7 l - 12°± 5°to TDC
8. If the basic ignition timing does not match the nominal value, then perform troubleshooting and check the components of the fuel injection system.
9. Press the reset button on the tester to disable the basic lead mode (item Actuator Test).
Attention: if this is not done, then the forced control mode of the device will be saved for 27 minutes. Driving under these conditions can damage the engine.
Note:
- Even during normal engine operation, the ignition timing changes within +5°.
- As the altitude increases, the ignition timing automatically increases.
10. Disconnect the stroboscope.
11. Turn off the ignition and disconnect the tester.
