    Hello guys,

    I'm having a problem with TEVES system ( I have downloaded the workshop manual with all th einfo) for this euro 95-96 F355. We managed to check the GAP of the sensors in the 4 corners, they are fine. We checked the wires/signals and all are good. We tested/tried another TEVES ECU from a running trouble free F355 in this particular car and still managed to get the same 36 code (flashing the ABS light) if memory is right ( I will double check tomorrow for it) and the DTC chart said it was lag of signal/gap or controller internal problem. But before swapping the ECU test, we purchased a used TEVES ECU and got the same code.

    I'm running out of ideas what can cause this issue. There's no SD1 tool available in my country, my AUtel MaxiSystem ELite only has the FIAT 3 PIN adapter to OBD2 and the software only shows the BOSCH system to scan. There's any other way to scan or check the system?

    Thanks

    Found this searching, not sure if it helps but its something. From 348 but I imagine Teves is Teves. Sounds like a failed sensor perhaps?

    35-38: Intermittent lack of signal due to wire breakage or short circuit or internal ECU failure...or due to faulty electrical contacts...or due to irregular ring gear movement...or due to excessive bearing play...or due to Gap too large or small (35=left front, 36=right front, 37=right rear, 38=left rear)


    Code Number Diagnosis
    11 open circuit in solenoid relay circuit
    12 short circuit in solenoid relay circuit
    13 open circuit in pump motor relay circuit
    14 short circuit in pump motor relay circuit
    21 open or short circuit in 3 position solenoid of front right wheel
    22 open or short circuit in 3 position solenoid of front left wheel
    23 open or short circuit in 3 position solenoid of rear wheels
    31 front right wheel speed sensor signal malfunction
    32 front left wheel speed sensor signal malfunction
    33 rear right wheel speed sensor signal malfunction
    34 rear left wheel speed sensor signal malfunction
    35 open circuit in front left or rear right wheel speed sensor
    36 open circuit in front right or rear left wheel speed sensor
    41 abnormal battery voltage ( < 9.5 or > 17 )
    51 pump motor of actuator locked or open circuit in pump motor circuit in actuator
    ALWAYS ON computer malfunction

    Here are two documents. The first has test procedures in it starting at page 32. The second lists the DTC. The DTCs are from a Jag document. Teves is Teves?

    I would check the wiring harness for good continuity with an ohmmeter, as well as the sensors. And make sure you wiggle the harnesses around as the meter is hooked up to see if you get an intermittent open circuit. Good luck.

    A common Failure point for the system is the ribbon harness in the abs actuator unit. When mine failed, I found a lot of info on the BMW sites. Repair procedure etc.
    Good luck!

    It is not clear what parts you describe as "ribbon harness" and as "abs actuator unit". The ABS function is "actuated" (controlled) by the ABS ECU but it has no ribbon harnesses. There are no ribbon harnesses on the ABS Master Cylinder either.

    Did I miss your initial symptoms (what was/is wrong)?

    Great, thanks for the info. This is the Solenoid Block. I have not been in there yet but using ribbons does not seem to be a reliable design (the wired solution looks much better).

    A lot of good information but the original fault is code 36 which the computer indicates to be a bad signal from front right or rear left speed sensor. There are several recommended troubleshooting tips from the book and if he followed those tips, it should get him to resolve this.
