Code panne Yeti

Discussion dans 'Astuces, documentations et outillages' créé par SACAM, 12 Juin 2015.

  1. Le diagnostique de mon véhicule donne les code erreurs suivants :
    001617 - P0651
    008482 - P2122
    005488 - P1570
    je voudrais savoir quel sont les pièces incriminées pour résoudre ce problème.
    NB: la voiture ne démarre pas

    Salut,

    Voici les explications de tes codes de défauts

    Elle ne démarre pas à cause d'un problème avec l'Immobilizer >> [h=2]17978/P1570/005488 - Engine Start Blocked by Immobilizer[/h]
    Le plus simple prendre la deuxième clé et faire un test

    [h=2]17036/P0652/001618 - Sensor Reference Voltage B: Too Low[/h] [h=4]Possible Causes[/h]
    • Wiring/Connectors from/to Intake Manifold Pressure Sensor (G31) faulty
    • Intake Manifold Pressure Sensor (G31) faulty
    • Engine Control Module faulty
    [h=4]Possible Solutions[/h]
    • Check Wiring/Connectors from/to Intake Manifold Pressure Sensor (G31)
    • Check/Replace Intake Manifold Pressure Sensor (G31)
    • Replace Engine Control Module
    [h=4]Special Notes[/h]
    • When found in 1.9l TDI (BEW):
      • Check Atmospheric Pressure (MVB 010.2) and Intake Manifold Pressure Sensor (MVB 010.3). Compare both Values with Engine OFF, the Tolerance should be +/- 50 mbar.
      • Check Variable Nozzle Turbocharger (VNT). Specifically, check the electronic actuator position sensor G500 , including unplugging it for testing.
    • When found in other engines:
      • Check the factory repair manual since this fault can point to problems with several different sensors.
      • Specifically in the BLB engine, faulty MAF wiring can trigger it.
    [h=2]P2122/008482 - Accelerator Position Sensor (G79): Signal too low[/h] [h=4]Possible Symptoms[/h]
    • MIL On
    [h=4]Possible Causes[/h]
    • Faulty Accelerator Pedal Assembly
    • Wiring Harness Issue for Accelerator Pedal Assembly
    [h=4]Possible Solutions[/h]
    • Inspect Throttle Pedal and Wiring Harness. See Factory Repair Manual.
    [h=4]Special Notes[/h] The signal voltage for the Accelerator Pedal could be shared with other engine components, O2 sensors for example.

    [h=2]17978/P1570/005488 - Engine Start Blocked by Immobilizer[/h] [h=4]Possible Symptoms[/h]
    • Engine starting but stalling immediately
    [h=4]Possible Causes[/h]
    • Key(s) not matched
    • Instrument Cluster not matched
    • Engine Control Unit (ECU) not matched
    • Engine Control Unit (ECU) Power Supply faulty
    [h=4]Possible Solutions[/h]
    • Check for Fault Codes in Immobilizer itself (part of Instrument Cluster in many cars, but separate Immobilizer Control Module in some)
    • Check Immobilizer Measuring Values (usually in Instrument Cluster OR Immobilizer Control Module)
    • Match Key(s)/Instrument Cluster/Engine Control Unit (ECU)
    • Check Engine Control Unit (ECU) Power Supply (Relay)
    [h=4]Special Notes[/h]
    • In case of Engine Starting Issues please make sure that you are really experience an Immobilizer related Problem! Even if the Immobilizer engages, the Engine will still start fine but cut out after 2-3 Seconds. If you are NOT experiencing this behavior (e.g. Engine doesn't start at all) your Problem is very likely NOT Immobilizer related.
    • May be stored in Combination with 01176 - Key: Signal too Low in Immobilizer Control Module.
    • If no other immobilizer related fault codes are stored and the immobilizer related meas. blocks are fine except Engine Start not allowed, on rare occasions it helps to try cold-booting the car. Remove both battery cables from the battery. Short the battery cables together (away from the battery) for about 15 seconds. Reconnect the battery. (Example)
    • Low battery voltage (including a faulty battery) may cause Immobilizer system malfunctions and testing should be done only with a known good battery installed.
