Tip aus dem Forum: Informationen und Interface für ALDL, dem GM-Bussystem
Pontiac Transsport 3.8 Liter bis 1994
- Es sind nur 3 Pins der Diagnosebuchse belegt: rechts oben außen Masse, 2. von rechts oben Diagnose und rechts unten außen Serial Data.
- Diagnose- und Masse-Pin mit Jumper-Kabel überbrücken.
- Zündschalter in Stellung EIN drehen.
- MIL (Service Engine Soon) blinkt danach einen zweistelligen Fehlercode je 3 mal beginnend mit 12 (alles Normal).
- Blinkcode aufschreiben und mit Tabelle unten vergleichen.
- Fehlercodes löschen durch kurzzeitiges Abklemmen der Fahrzeug-Batterie.
- Zündung AUS und Jumper wieder entfernen.
