  4. Kuwunika kwadongosolo la EVAP: Pamene payipi yabwezeretsedwa ndikuyika moyenera, ndi bwino kuti dongosolo lonse la EVAP lidziwike pogwiritsa ntchito zipangizo zowunikira kuti muwone mavuto ena.
  5. Kuchotsa zolakwika: Pambuyo pokonza vutolo, muyenera kuchotsa nambala yolakwika ya P1478 kuchokera pagawo loyang'anira galimoto pogwiritsa ntchito scanner kapena zida zina zowunikira.
  6. Kuyesa ndi kuwongolera: Pambuyo pokonza, muyenera kuyesa dongosolo la EVAP kuti muwonetsetse kuti vutoli lathetsedwa ndipo palibe mavuto atsopano omwe abuka.

Ngati simungathe kukwaniritsa izi nokha, tikulimbikitsidwa kuti mulumikizane ndi makanika oyenerera kapena malo ochitira chithandizo kuti muzindikire ndi kukonza.
