Certain 19-23MY Kona Electric (OS EV) vehicles may experience a condition of EV warning light ON with DTC P1AA6 to P1AAF found stored. The Battery Management System (BMS) software update will be performed to enhance battery diagnostics logic. Flowchart summary of the service procedure is provided on page 2 summarized as follows: • Vehicles that do not have EV Warning Light On will only need the BMS software update. • Certain vehicles incurring EV Warning Light On and DTC P1AA6 found stored with Freeze Frame Data Information Code 1=128 will only require the BMS Update. • Certain other DTC P1AA6 Information Code 1-2 values or DTC P1AA7 to P1AAF will require the Battery System Assembly (BSA) to be replaced and then the BMS Update to be performed.

Flash: Battery Pack Control Module (BPCM) Diagnostic and System Improvements This bulletin involves reprogramming the BPCM with the latest available software. Customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation, a technician may find one or more of the following Diagnostic Trouble Codes (DTCs) have been set:P0AA1-00 - Hybrid Battery Positive Contactor Circuit Stuck Closed (After the vehicle is turned off, it may fail to restart). P0AA6-00 - Hybrid Battery Voltage System Isolation Fault. P1E1B-00 - Hybrid-Ev Battery Side Voltage System Isolation.Under a vehicle side isolation failure which generates P0AA6, the BPCM may falsely set P1E1B (HV battery isolation failure) on key off which results in a no start condition.
