Li-PID tse tloaelehileng
Tafole e ka tlase e bonts'a li-PID tse tloaelehileng tsa OBD-II joalo ka ha li hlalosoa ke SAE J1979. Karabelo e lebelletsoeng bakeng sa PID ka 'ngoe e fanoe, mmoho le tlhahisoleseling ea mokhoa oa ho fetolela karabo ho data e nang le moelelo. Hape, ha se likoloi tsohle tse tla tšehetsa li-PID tsohle mme ho ka ba le li-PID tse hlalositsoeng ke moetsi tse sa hlalosoang ho latela maemo a OBD-II..
Hlokomela hore mekhoa 1 le 2 li tšoana hantle, haese Mokgwa oo 1 e fana ka lintlha tsa morao-rao, athe Mode 2 e fana ka sets'oants'o sa data e ts'oanang e nkiloeng nakong eo khoutu ea ho qetela ea bothata ba ho hlahloba e behiloe. Mekhelo ke PID 01, e fumanehang feela Moemong 1, le PID 02, e fumanehang feela Moemong 2. Haeba Mode 2 PID 02 e khutlisetsa zero, joale ha ho na snapshot le Mode tse ling kaofela 2 data ha e na moelelo.
