    Unable to delete faults

    Regarding my BMW E61 523i from 2007

    I recently got the "Restraint system" failure. Reading out the error codes I see 93FC and 93FD error codes,]Battery lead, positive/ground (monitoring of shielding), indicating a problem with the main battery cable. I have inspected the accessible parts of the battery cable, and see no problems.

    I have tried deleting the errors with INPA, I can only delete the regular error memory, INPA has the option of deleting the history memory, but that option fails. Deleting the regular memory does nothing, if I read out errors immediately after I get the same errors again, the error lights in the dashboard never disappear.

    I have also tried to delete the errors with the Android app "Deep OBD for BMW and VAG" but I get similar results as with using INPA.
    I am connecting to the car using an OBD k+DCAN cable.

    Does anyone know how I can delete the errors, or correct the problem?

    Error readout:
    SIM/SGM (Crash safety module):
    Error code: 93FC
    ACSM/MRS: Battery lead, positive (monitoring of shielding), Fault currently present, implausible measured values
    Environmental conditions:
    - Frequency: 9
    - Logistics counter: 40
    - Mileage/km reading: 194984 km

    SIM/SGM (Crash safety module):
    Error code: 93FD
    ACSM/MRS: Battery lead, ground (monitoring of shielding), Fault currently present, implausible measured values
    Environmental conditions:
    - Frequency: 2
    - Logistics counter: 40
    - Mileage/km reading: 194984 km

    SIM/SGM (Crash safety module):
    Error code: 93B2
    ACSM/MRS: Safety battery terminal, Fault currently present, implausible measured values
    Environmental conditions:
    - Frequency: 1
    - Logistics counter: 40
    - Mileage/km reading: 197376 km
    The error 93B2 is from my previous attempts at diagnosing the problem, I disconnected the battery safety terminal, and reconnected it again, but I am unable to delete this error as well.

    That essentially means the problem is still there, you may have to trace the wiring with a multimeter and find any faults before it will clear.

    That is what I thought as well, that just does not explain why the 93B2 error has not cleared as well, that error occured because I disconnected the Battery Safety Terminal, and I have since reconnected the BST, and cleared the error codes, but the error code remains.
