GM Diagnose

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.

Der 3.8L Pontiac Transsport enthält bis inkl. Baujahr 1993 das ECM 16141470, das mit einer ALDL 8192 Baud Hardware ausgelesen werden kann vgl. http://pweb.de.uu.net/pr-meyer.h/aldl.htm

Herr Stuhlfelder hat sich inzwischen weiter mit dem Pontiac Transsport 3.8L 1993 beschäftigt und Informationen, Downloads auf www.pontiac-transsport.de bereitgestellt. Auf Anfrage sind bei ihm auch weitere, von ihm geschriebene Programme dazu (ABS, Lüfter, Klima usw.) erhältlich. (Stand 09.12.2003)
