    The document describes a diagnostic trouble code (DTC) P0B3B for a battery voltage sensor internal circuit error. The electric power plant-controller area network (EPP-CAN) transmits pulsing signals to and from the battery voltage sensor using two signal lines. If abnormal internal failure information or data order is received from the sensor for over 200 times in 2 seconds, the motor control module will detect a malfunction and store the DTC. The malfunction indicator light will illuminate and data will be stored until the issue does not return over 3 trips with diagnostic running.

    VOLTAGE MODULE
    EPP-CAN SENSOR

    02_P0B3BG_TX8D00
    The electric power plant-controller area network (EPP-CAN) transmits/receives pulsing signals to/from the battery voltage
    sensor simultaneously by using two signal lines (EPP-CAN_H and EPP-CAN_L). If the internal failure information from the
    battery voltage sensor via the EPP-CAN lines are received for a specified time within a set duration, or if the order of the data
    from the battery voltage sensor via the EPP-CAN lines are abnormal for a specified time within a set duration, the motor
    control module (MCM) detects a malfunction and stores a DTC.
    Monitor Execution, Sequence, Duration, DTC Type, OBD Status
    Execution Continuous
    Sequence None
    Duration 2 seconds or more
    DTC Type One drive cycle, MIL on, IMA system indicator on
    OBD Status PASSED/FAILED/NOT COMPLETED (STILL TESTING)

    Enable Conditions
    Condition Minimum Maximum
    Elapsed time since the battery
    voltage reaches to a specified
    value after the ignition switch is
    3 seconds –
    turned to ON (II), or the engine
    start/stop button is pressed to
    select the ON mode
    Battery voltage 10.2 V –
    No active DTCs set (prevents
    U029A
    monitor from running)

    Malfunction Threshold
    One of these conditions is met:
    • The internal failure information from the battery voltage sensor via the EPP-CAN lines are received for at least 200 times
    within 2 seconds.
    • The order of the data from the battery voltage sensor via the EPP-CAN lines are abnormal for at least 200 times within 2
    seconds.

    Diagnosis Details
    Conditions for setting the DTC
    When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in
    the MCM memory.
    Conditions for clearing the DTC
    The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the
    Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by
    disconnecting the battery.
