Engine-Check, wer kann mir mit den Fehlercodes weiterhelfen

[ICE-T]

Hallo,

ich habe ein kleines Problem

Nachem ich gestern einen neune MAF-Sensor und einen anderes Filtersystem eingebaut habe und dabei scheinbar die Batterie völlig entladen wurde (mußte die Pufferstange abbauen und dabei leuchtete die Standbeleuchtung).

Dann Kurz mit Ladegerät angeladen und dann auf Startstrom gestellt, falls das so heißt ist das gute Stück aber trotzdem nicht angesprungen. Weiter aufgeladen und dann ist es problemlos gegangen.

Vette nach Hause in die Gerage gestellt und Ladegerät über Nacht rangehängt.

Heute morgen wollte ich zum Amitreffen nach Hannover fahren und habe bei der Fahrt gesehen, das die "Engine-Check-Lampe" leuchtete. Bis Braunschweig (ca. 35 km) ist sie beharlich angeblieben, dann nach H und zurück und sie ist immer noch an.

Fehlercodes ausgelesen, aber technisch nicht so versiert, kann ich mit den Meldungen nicht so viel anfangen.

Vielleicht kann mir da ja jemand weiterhelfen.

Folgende Fehlercodes habe ich gerade ausgelesen:

-10PCM 2Codes (P0171 H & P0174 H) Lt. Kaufberatung: Fuel Trim System Lean Bank 1B6 2B)
-A0 LDCM 1Code (U1064 H)
-A1 RDCM 1Code (U0164 H) Lt. Kaufberatung: Loose of Communication with DOB
-A6 SCM 1 Code (U1064 H)
-B0 RFA 3Codes (U1096 H, U1064 H, C2121 C) Lt. Kaufberatung: Loose of Communication with IPD, ? , TPM System Programming malfunktion (No Sensor Programmed) TPM

Ich hoffe das ich mich Verständlich ausgedrückt habe.

Meine irgendwo auch mal gelesen zu haben, das das System nach einen kompletten Trennen von der Stomzufuhr (Batterie total leer ?) erst wieder eine weile Laufen muß um neu zu Lernen.

Ich würde sehr gerne wieder etwas ruhiger hinter dem Steuer sitzen und hoffe das Ihr mir weiterhelfen könnt.


Vielen, vielen Dank

Gruß

Hi Thorsten,

bist Du doch schon wieder zurück aus der Landeshauptstadt?

Bis auf einen sind alle Codes mindestens 5 Startzyklen alt (H = History). Der erste von Dir genannte Code hat irgendetwas mit Treibstoff zu tun. Unter Umständen hängt das mit Deiner Reparatur des Tank-Entlüftungssystems zu tun?

[Petra]

Da kann ich dir helfen. Ich war auf die suche wie ich meinen radio unlochen konnte.
In meinen suche fand ich die fehler meldung:

Turn the key to the ON position, but don't start the engine. Clear any present messages by pressing the RESET button. Hold the OPTIONS button down, and press the FUEL button 4 times. This will get you into the CODES section of the DIC. The computer will automatically display all the codes your car has created. It will cycle through each code every 3 seconds. Any code that ends in H is a history code (something that has occured in the past) but is fine now. Once the computer has finished going through all of it's codes, press RESET to enter Manual Configuration mode. It should start with a module and show "NO CODES" or "# CODES".

To optionally reset the codes once in manual mode, press and hold RESET until it displays "NO CODES". Press OPTIONS to go to the next module. Repeat the steps in this paragraph until you have reset the codes in all the computer modules. NOTE !! Only reset the codes IF you want to - it is NOT necessary to do this.

Hallo Thorsten

... und habe bei der Fahrt gesehen, das die "Engine-Check-Lampe" leuchtete.

Genau das gleiche ist mir, und einer Bekannten auch, nach einer Batterieentladung passiert. Bin aber damals nur ca 20 km gefahren. Am nächsten Tag war dann die "Engine-Check-Lampe" wieder aus. Auch bei meiner Bekannten war die Lampe nach etwa 24h wieder aus.

Die Fehlercodetabelle aus Mannis Checkliste hat damals auch irgendwas mit Battery fault und loss communication ausgespuckt.

Das mit der "Engine-Check-Lampe" ist scheinbar normal, als Reaktion auf auf eine entladene Batterie.

Vollgeladene Grüsse, Harald

[ICE-T]

@Petra

danke für Deine Aufstellung, allerdings ist das die gleiche wie in der Kaufberatung,

trotzdem DANKE für Deine Hilfe

@TeraVolt

Hallo Harald,

das ulkige ist halt gewesen, das sie nach der kompletten Entladung nix angezeigt hat und nachdem ich sie aufgeladen hatte am nächsten Morgen diesen Mist angezeigt hat.

Diese "Loose of Communication"-Fehler könnte ich mit der fehlenden Batteriespannung in Verbindung bringen. Aber die "Fuel Trim System Lean Bank"-Fehler haben nach meinem Verständnis was mit dem Kraftstoff zu tun (zu wenig in 1B&2B vorhanden????)

Was dieser "TPM System Programming malfunktion (No Sensor Programmed) zu sagen hat, weiß ich leide noch nicht.

@Manni

Ja bin bzw. hoffentlich sind wir wieder zurück. Denny mußte ja noch tanken und ich bin schon mal vorgeschlichen. Auf der Bahn bin auch nur 120 gefahren, aber kein Denny in Sicht bis BS. Hoffe er ist heile angkommen

War nicht mehr lustig dort, habe den mega Sonnenbrand, war ja wieder viel zu warm und im Dinners haben wir bestimmt 20 min. gewartet bis uns endlich jemand bedienen wollte.
An Fzg. hat sich auch nicht mehr viel getan und dann sind wir nachdem Dakota und Porta die Biege gemacht hatten auch verschwunden.

So die ersten Fehler sehe ich genauso. Könnte davon kommen, obwohl ich denke das sie nach der Arbeit die Fehler gelöscht haben.
Ich habe mal versucht nachzuvollziehen wie oft ich das Auto angemacht habe und bin auf genau 5 mal gekommen bis er gestern in der Garage stand.

Dieser "C-Fehler" ist aber leider noch da.

Wie kann ich denn die Fehler löschen ??

Dank & Gruß

Thorsten

Hi Thorsten!

Wie kann ich denn die Fehler löschen ??

Steht oben über Petras Auflistung.

Hallo Thorsten.
Der einzige "Current" Code (C2121) hat nix mit dem aufleuchten der MIL zu tun.
Dein Wagen lief laut den Codes P0171 und P0174 auf beiden Zylinderbänken zu mager. Dies ist wohl der Grund für das aufleuchten der MIL. Normalerweise erlischt die MIL dann aber irgendwann wieder. Habe mal meine SI2000 Software befragt (das "interaktive" GM Service Manual). Hier ist was ich bekommen habe (interessant ist auch der letzte Satz, wo auf eine undichte Vacuumleitung hingewiesen wird - wie Du weißt verändert sich das Vacuum im Ansaugtrakt bei verbau eines offenen Luftfiltersystems . . .):

DTC P0174 Fuel Trim System Lean Bank 2
Circuit Description
The powertrain control module (PCM) controls a Closed Loop air/fuel metering system in order to provide the best possible combination of driveability, fuel economy, and emission control. The PCM monitors the heated oxygen sensor (HO2S) signal voltage and adjusts the fuel delivery based on the signal voltage while in Closed Loop. A change made to the fuel delivery changes the long and short term fuel trim values. The short term fuel trim values change rapidly in response to the HO2S signal voltages. These changes fine tune the engine fueling. The long term fuel trim values change in response to trends in the short term fuel trim. The long term fuel trim makes coarse adjustments to fueling in order to re-center and restore control to short term fuel trim. You can use a scan tool in order to monitor the short and long term fuel trim. The ideal fuel trim values are around 0 percent. A positive fuel trim value indicates that the PCM is adding fuel in order to compensate for a lean condition. A negative fuel trim value indicates that the PCM is reducing the amount of fuel in order to compensate for a rich condition. If the PCM detects an excessively Rich or Lean condition, the PCM sets a diagnostic trouble code (DTC). The long term fuel trim diagnostic parameter is an average of several of the long term speed load learn cells which the PCM selects based on the engine speed and the engine load.
Conditions for Setting the DTC
DTCs P0101, P0102, P0103, P0107, P0108, P0112, P0113, P0117, P0118, P0120, P0121, P0125, P0220, P0221, P0225, P0226, P0300, P0335, P0336, P0351, P0352, P0353, P0354, P0355, P0356, P0357, P0358, P0410, P0412, P0418, P0430, P0500, P0502, P0503, P1111, P1112, P1120, P1121 P1125, P1220, P1221, P1258, P1415, P1416, P1441, P1514, P1515, P1516, P1517 not set
The engine coolant temperature is between 60°C (120°F) and 115°C (239°F).
The fuel trim learn is enabled.
The barometric pressure is greater than 72.5 kPa
The mass air flow is between 4 g/s and 150 g/s.
The manifold absolute pressure is between 20 kPa and 90 kPa.
The intake air temperature is between -25°C (-13°F) and 115°C (239°F).
The EVAP canister purge is not enabled or the EVAP canister purge duty cycle greater than 75%.
The engine speed is between 500 RPM and 4500 RPM.
The TP sensor angle is less than 80%.
The vehicle speed is less than 137 km/h (85 mph).
The PCM detects the average Long Term Fuel Trim cell values are above a predetermined threshold.
All the above conditions met for 12 seconds.
Action Taken When the DTC Sets
The PCM illuminate the Malfunction Indicator Lamp (MIL) on the second consecutive drive trip that the diagnostic runs and fails, if the diagnostic fails under the same conditions (load, RPM, temperature, etc.) as the previous ignition cycle that the test ran and failed.
The first time the diagnostic fails, the PCM records the operating conditions in Failure Records.
The second consecutive drive trip that this diagnostic fails [under the same conditions (load, RPM, temperature, etc.) as the previous ignition cycle that the test ran and failed], the PCM stores this information in Freeze Frame. The PCM copies any data previously stored in Freeze Frame and copies the data into the Failure Records. The PCM then overwrites the Freeze Frame. The only exception to this is if a Misfire DTC was already recorded in Freeze Frame. In this case, the Misfire data stays in Freeze Frame and the PCM updates the Fuel Trim data in the Failure Records.
Conditions for Clearing the MIL/DTC
The PCM turns the MIL OFF after three consecutive drive trips that the diagnostic runs and does not fail within the same conditions that the DTC last failed.
Important
If the last failure was during a non-typical driving condition, the MIL may remain ON longer than the three drive trips. Review the Freeze Frame/Failure Records for the last failure conditions.
A History DTC clears after forty consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures.
A last test failed (Current DTC) clears when the diagnostic runs and does not fail.
PCM battery voltage is interrupted.
Use a scan tool in order to clear the MIL/DTC.
Diagnostic Aids
This DTC sets if the engine runs out of fuel.
A fuel delivery malfunction causes this DTC to set. Thoroughly inspect all items that cause a lean condition.
For an intermittent condition, refer to Symptoms .
Test Description
The numbers below refer to the step numbers on the diagnostic table.

This test determines whether the fault is present. For any test that requires probing the PCM or a component harness connector, use the Connector Test Adapter Kit J 35616-A . Using this kit prevents damage to the harness connector terminals.

Using the Freeze Frame and/or Failure Records data may aid in locating an intermittent condition. If you cannot duplicate the DTC, the information included in the Freeze Frame and/or Failure Records data can help determine how many miles since the DTC set. The Fail Counter and Pass Counter can also help determine how many ignition cycles the diagnostic reported a pass and/or a fail. Operate the vehicle within the same freeze frame conditions (RPM, load, vehicle speed, temperature etc.) that you observed. This will isolate when the DTC failed. For an intermittent condition, refer to Symptoms .

If DTC 171 is also set indicates both banks of the engine are operating lean. Inspect items that would cause both banks to operate lean.

A vacuum leak will cause DTCs P0171 and P0174 to set at the same time. Inspect all areas of the engine for a vacuum leak. Also inspect PCV valve for being the correct one for this application. Make sure the engine oil fill cap is in place and that it is tight. Check that the engine oil dip stick is fully seated.

Leider ist mein Englisch ganz schön eingerostet und nicht so auf Techn. Sachen ausgelegt.

Was könnte denn das als Kurzform bedeuten

Ist es denn so, das der Motor erst eine "Eingewöhnungsphase" zum Lernen braucht oder muß ich mir jetzt ernsthafte Gedanken machen.

Ich weiß Fragen über Fragen, wäre aber nett, wenn Du einem kl. Dummerchen weiterhelfen könntest.

Danke & Gruß

Hi,

den C2121C habe ich auch. Gibt es dafür eine bessere Erklärung als "TPM System Programming Malfunction (No Sensors Programmed)"? Kann ich leider nicht viel mit anfangen ...

Danke
Gruss
