Service Engine Soon
Fall bei Ihrem Fahrzeug die SERVICE ENGINE SOON oder CHECK ENGINE Kontolle leuchtet, bedeutet das nicht, daß ein Ölwechsel fällig ist. Vielmehr ist dies ein Warnhinweis, dass mit Ihrem Motormanagement (Elektronik) etwas nicht in Ordnung ist. Was tun? Im Normalfall deutet dieses auf die Fahrt in die nächste Werkstatt hin.

Da aber oft auch kleine technische Fehler angezeigt werden und vor allem nicht immer eine kompetente Werkstatt in der Nähe ist haben

Sie folgende Möglichkeit. (Leider nur wenn Ihr Fahrzeug vor 1996 hergestellt wurde). Sie können den vorhanden Fehlercode selber auslesen und das ohne teures Werkzeug. Gehen Sie wie folgt vor. (bitte mit Sorgfallt) Legen Sie sich ein Stück Draht oder eine Büroklammer bereit.

So wird's gemacht:

1.) Suchen Sie an Ihrem Fahrzeug den vorhanden Diagnosestecker (ALD Conector). Bei GM Fahrzeugen meist unter der Lenksäule.

2.) Bereiten Sie die Büroklammer (aufbiegen) vor, oder isolieren Sie ein ca. 5 cm langes Kabel an beiden Enden ab.

3.) Suchen Sie in dem Diagnosestecker nach den Buchstaben A und B.

4.) Jetzt stecken Sie das eine Ende des Kabel in Kontakt A und das andere in Kontakt B. (sie bauen eine Kabelbrücke)

5.) Schalten Sie die Zündung eine.( nicht den Motor starten)

6.) Beobachten Sie nun die Service Engine Soon Lampe bzw.Check Engine.

7.) Nun wird der vorhanden Fehlercode 3 mal angezeigt. Sollten Sie mehrere Fehlercodes haben so werden dieses jeweils 3 mal angezeigt.

ACHTUNG: der erste dreimalige Blinkcode ist nur zur Kontrolle des Systhems, dass heißt, die ersten drei wiederkehrenden Blinksignale sind für Sie nicht relevant.
Das ganze könnte dann so aussehen.

Blink- Pause- Blink-Blink- lange Pause (Code 12 Diagnose)
Blink- Pause- Blink-Blink- lange Pause (Code 12 Diagnose)
Blink- Pause- Blink-Blink- lange Pause (Code 12 Diagnose)

danach wirds wichtig ( folgender Fehlercode könnte kommen)

Blink-Pause-Blink-Blink-Blink-lange Pause (Code 13 =O2 Sensor)
Blink-Pause-Blink-Blink-Blink-lange Pause (Code 13 =O2 Sensor)
Blink-Pause-Blink-Blink-Blink-lange Pause (Code 13=O2 Sensor)

weitere Fehlercodes könnten nun noch folgen.

8.) Nach dieser Aktion den Draht entnehmen. Zum löschen der Fehlercodes die Batterie ca. 10 Sekunden abklemmen. Allerdings sollte dies nur bei kleinen Fehler gemacht werden. Dieses Systhem dient natürlich nur zur Erkennung von Fehlern, ein Austausch des defekten Teils ist natürlich nötig. Anhand der aufgeführten Fehlercodes könne Sie in den meisten Fällen den Fehler ermitteln. Unsere Kunden aus der näheren Umgebung haben natürlich die Möglichkeit diesen Fehler mittels unserem Diagnosegerät ermitteln zu lassen. Einfach kurz anrufen und vorbeikommen.
