Jeg skriver dette indlæg, da jeg har kæmpet en del med min Golf 2 1,8 med monopint indsprøjtning.
Udlæsning af fejlkoder var sort land for mig indtil jeg læste Mogens\' guide her på golf2.dk.
Se den her: http://www.golf2.dk/index.php?action=gu ... ide_id=210
Jeg kunne dog ikke få Mogens system med diode og modstand til at virke, så jeg forsøgte mig med at måle spændingen på det gule teststik.
Og det gik meget bedre.
Se billederne og forklaringen til det enkelte billede.
Fejlkodernes betydning finder I i Mogens' rigtig gode vejledning, eller på nettet.
Du starter her:
Billede 1:
Mine to stik. Sådan to skal du lige have lavet.
Det er blot to 2mm popnitter hvor sømmet er banket fladt. Det må godt være fladere end vist. Jeg har så klippet lidt af spidsen med en skævbider, for at spidsen nemmere gik ned i stikket. Det havde nu ikke rigtig nogen virkning.
- Billede 1
Her gemmer det gule stik sig: Under gearstangs manchetten. Popnitterne har jeg allerede sat i stikkene.
- Billede 2
Det sorte stik. Rød er +12v altid, også med slukket bil....
Brun er stel, det er den der skal bruges.
- Billede 3
Multimeterets røde plus ledning sættes på det gule stik.
Den sorte minus til stel/0 på det sorte stik.
Senest på det her tidspunkt startes motoren.

Her kortslutter jeg til stel, i 6 sekunder, for at starte fejlkode udlæsningen.

Dette billede viser måleinstrumentets opførsel.
Ved start af motor vises ca 2volt.
Ved kortslutning i 6 sekunder, vises kortvarigt 0v.
Derefter 8v kortvarigt.
Så falder visningen til 2v i små hidsige spjæt.
Tæl dem! ...
Den falder 1 til 4 gange, derefter kortvarigt 8v igen. Det var det tal.
Sekvensen gentages ialt 4 gange, så du får den 4cifrede kode.
Spændingen dropper til 0v
Så 8v, og så viser den koden igen.

Jeg kaster lige fejlkoder ind her for nu viser min motor en sær fejl der ikke er må Mogens liste.
Listen er fra et californisk dokument ....
