OBD II Fault Code


    OBD-II Code Diagonostic Trouble Code is defined as a Hybrid Battery Pack Voltage Sense "A" Circuit Intermittent/Erratic

    The high voltage battery is composed of many individual battery cells (sometimes over 300 cells). Those cells are then grouped together. each group has a voltage monitor attached to it that tells the battery control module (or hybrid powertrain control module) the available voltage for each cell group. If a cell group's voltage is less than what it should be, code P0ABE is set.

    Common Problems That Trigger the P0ABE Code

    • Battery contactor assembly failure
    • Battery Energy Control Module (BECM) failure
