Injector calibration

After replacement of injectors or engine control unit, the injectors' injection time needs to be calibrated. The engine control unit indicates that calibration is needed with a flashing engine warning light. After a successful calibration, the engine warning light stops flashing.
During the time that calibration is in progress the idle rpm may vary.
Note:
Before calibration is performed, drive and warm up the vehicle for approx. 15-20 minutes so that engine and automatic transmission (if the vehicle is equipped with one) become really warm.
If test conditions are outside the vehicle's calibration conditions when idling, the function may be difficult to run or cancel. In case of incorrect test conditions, the text "Unable to execute command" is shown. To initiate calibration again, the ignition key must be turned on/off.
Test conditions:
Procedure:
  1. Select the function 'Fuel quantity learning procedure, press "OK".
  2. Wait for correct engine temperature, 80 - 90°C, press "OK".
  3. Let the engine idle during the whole procedure, approx. 3 minutes.
  4. Check that the engine warning light has stopped flashing after finished calibration.
