    Default ABS blinking codes, how do you read them (resolved)

    I found the ABS blinking codes but the instructions say you need to press brake pedal and the ASC button at the same time but what do you do if you don't have a ASC button?

    Also does any one know how to deactivate the ABS ?

    Found out it was a broken wire on the left front sensor. Ran an ohm meter on the right side and got ~900 to 1000. Then when I ran the left side got nothing. Pulled the sensor and wire, pushed a needle through each of the two wires up near the sensor and test each of the two leads. Got continuity on the black wire but the red no continuity. Feeling along the wire found an area that was more flexible. Pushed and pulled on the wire in this area and the continuity jumped around on the meter. Pulled the wire apart cleaned up the ends and soldered them back together. Used heat shrink tubing to finish it off. Silicone on any cracks. Reinstalled the sensor and ABS works fine. Cheap fix.....the alternative was to spend +$100 for a new sensor.

    that everyone understands what he is talking about, he got from me this info for the E32:

    ABS/ASC blink test code
    Only posible on newer E32
    German version:

    ABS/ASC-Blink-Code

    - Bremspedal und Schalter "ASC" gleichzeitig drücken
    - Zündung "an"
    - Bremspedal und Schalter loslassen
    - ASC-LEUCHTE fängt an zu blinken
    BC = BlinkCode

    BC 1 = kein Fehler
    BC 2 = EMS Fehler
    BC 3 = Motronic Fehler (DME/ EMU)
    BC 4 = Drehzahlgeber Fehler hinten links
    BC 5 = Drehzahlgeber Fehler hinten rechts
    BC 6 = Drehzahlgeber Fehler vorne rechts
    BC 7 = Drehzahlgeber Fehler vorne links
    BC 8 = ABS-Magnetventil hinten links
    BC 9 = ABS-Magnetventil hinten rechts
    BC10 = ABS-Magnetventil vorne rechts
    BC11 = ABS-Magnetventil vorne links
    BC12 = ASR-Plungenventil Fehler hinten links
    BC13 = ASR-Plungenventil Fehler hinten rechts
    BC14 = Ventilrelais Fehler
    BC15 = Rückförderpumpen Fehler
    BC16 = Speicherladeventil Fehler
    BC17 = Langzeitfehler Druchüberwachung
    BC18 = Leckage Fehler (Wird auch angezeigt wenn Druckspeicher(Gaspatrone) im ASC+T Hydraulikblock schadhaft ist (zB. leer))
    BC19 = Druck Fehler
    BC20 = Getriebebeinflussung Leitungsfehler
    BC21 = ABS/ASR-Regelgeräte Fehler
    BC22 = TD-Signal Fehler (dürfte Tachoimpuls sein)
    BC23 = Option pin Leitungs Fehler

    Zu BC 22:
    TD Signal Fehler
    Regelgerät Kl. 55
    Zündung aus
    Stecker vom ABS/ASR-Regelgerät und Motronic-Steuergerät Bank links abziehen
    Leitung vom ABS/ASR-Regelgerät Kl.55 zum Motronic- Steuerg. Kl.6 auf Unterbrechung/Plus-/und Masseschluß prüfen.
    wenn i.O.
    Fehlerspeicher Motronic auslesen
    wenn i.O.
    ABS/ASR-Regelgerät tauschen
    -------------------------------------------------------
    Translation, hopefully correct:

    - push brake pedal and ASC switch simultaneously
    - Zündung "an" / ignition on
    - Bremspedal und Schalter loslassen /release brake pedal + ASC switch
    - ASC-LEUCHTE fängt an zu blinken/ASC light starts to blink
    BC = BlinkCode

    BC 1 = kein Fehler / no fault
    BC 2 = EMS Fehler / EMS fault
    BC 3 = Motronic Fehler (DME/ EMU)/ DME/EMU fault
    BC 4 = Drehzahlgeber Fehler hinten links/fault speed indicator rear left
    BC 5 = Drehzahlgeber Fehler hinten rechts/fault speed indicator rear right
    BC 6 = Drehzahlgeber Fehler vorne rechts/fault speed sender front right
    BC 7 = Drehzahlgeber Fehler vorne links/fault speed sender front left
    BC 8 = ABS-Magnetventil hinten links/ABS solenoid valve rear left
    BC 9 = ABS-Magnetventil hinten rechts/ABS solenoid valve rear right
    BC10 = ABS-Magnetventil vorne rechts/ABS solenoid valve front right
    BC11 = ABS-Magnetventil vorne links/ABS solenoid valve front left
    BC12 = ASR-Plungenventil Fehler hinten links/fault ASR plunger valve rear left
    BC13 = ASR-Plungenventil Fehler hinten rechts/fault ASR plunger valve rear right
    BC14 = Ventilrelais Fehler/ fault valve relay
    BC15 = Rückförderpumpen Fehler/ fault recycling pump
    BC16 = Speicherladeventil Fehler/fault storage load valve
    BC17 = Langzeitfehler Drucküberwachung/fault long time pressure control
    BC18 = Leckage Fehler (Wird auch angezeigt wenn Druckspeicher(Gaspatrone) im ASC+T Hydraulikblock schadhaft ist (zB. leer))
    leakage fault (is also shown when pressure vessel (gas bomb) in ASC_T hydraulic block is damaged (for example empty))
    BC19 = Druck Fehler/ fault pressure
    BC20 = Getriebebeinflussung Leitungsfehler/fault pipe transmission control
    BC21 = ABS/ASR-Regelgeräte Fehler/fault ABS/ASR regulators
    BC22 = TD-Signal Fehler (dürfte Tachoimpuls sein) TD-signal fault (should be the speed impulse)
    BC23 = Option pin Leitungs Fehler/option pin line fault

    Zu/to BC 22:
    TD Signal Fehler/TD signal fault
    Regelgerät Kl. 55/ regulator terminal 55
    Zündung aus /ignition off
    Stecker vom ABS/ASR-Regelgerät und Motronic-Steuergerät Bank links abziehen/disconnect from the ABS/ASR regulator unit and MOTRONIC module bank left the connectors
    Leitung vom ABS/ASR-Regelgerät Kl.55 zum Motronic- Steuerg. Kl.6 auf Unterbrechung/Plus-/und Masseschluß prüfen.
    check the line from ABS/ASR regulating unit terminal 55 to MOTRONIC- control module terminal 6 for interruption/plus-/and ground connection
    wenn i.O./ in case that is o.k.,....
    Fehlerspeicher Motronic auslesen/read fault codes
    wenn i.O./in case that is o.k.,....
    ABS/ASR-Regelgerät tauschen/change ABS/ASR control unit

    wow thats cool! I will try it with the 850 and see what it is trying to tell me. The stomp test does not work with that car either.
