ALDL OBD1 Kommunikationsprobleme

[thefbi]

Hallo Marco,

soooooo, vorab, es geht!!!

Ich habe zuerst einmal die Batterie für einige Minuten abgeklemmt, um das PCM mal stromtot zu machen. Nach dem Wiederanklemmen habe ich das EFILive gestartet und dein Makro gestartet. Dabei ergab sich folgendes Log:

DataMaster spuckte noch immer die selbe Fehlermeldung vom unbekannten PCM aus.
Ich bin dann im EFILive mal auf "Automatically Detect Chatter" gegangen, und schwub, hat er was gemacht (1.Bild). Danach konnte ich dein Makro laufen lassen, und er hat mir zum Beispiel den TPS Wert angezeigt. Ich habe dann das Auto gestartet, EFILive zeigte dann auch deutlich mehr an. Bei laufenden Motor das EFILive beendet, DataMaster gestartet, Com-Test, und es lief auf einmal auch (2. und 3. Bild). Ich hoffe meine Werte sind ok und das ganze läuft beim nächsten mal dann auch wieder.

Besten Dank auf jeden Fall nochmal für deine Hilfe,

Gruß, Frank
