HIGH-VOLTAGE BATTERY PACK AND BATTERY MANAGEMENT SYSTEM (SC267)

This bulletin provides information regarding High-Voltage Battery Pack and Battery Management System (BMS) for the subject vehicles below. An electrical short circuit between the anode and cathode of the battery cells can occur within the high-voltage battery pack assembly (BPA) case located underneath the vehicle. If an electrical short circuit occurs, a fire may result while driving, thereby increasing the risk of injury.

 

For the affected 2015-2017 MY SOUL EV vehicles manufactured from July 15, 2014 through June 30, 2017 that had their high-voltage battery replaced under warranty with an E400 battery (P/N: 37510E4200/E4200R/E4250/E4250R), dealers are to:

  • First, replace the BMS and the Voltage & Temperature Sensor Wiring Harness (VTSWH),
  • Update the BMS with new software in ‘Manual Mode’ only, and
  • Inspect the High-Voltage Battery and, in necessary, replace it with a new one.

For all 2018-2019 MY SOUL EV vehicles manufactured from July 3, 2017 through September 28, 2018 equipped with an E400 high-voltage battery, dealers are to:

  • Update the BMS with new software, and
  • Inspect the High-Voltage Battery and, if necessary, replace it with a new one

Before conducting the procedure, verify that the vehicle is included in the list of affected VINs.

 

Operation Descriptions:

  • BMS Software (BMS S/W)
  • High Voltage Battery Pack Assembly (HV BPA)
  • Voltage & Temperature Sensor Wiring Harness (VTSWH)
  • Battery Management System (BMS)

Note: For 15-17MY only, the two (2) VTSWH previously installed on the existing HV BPA will need to be swapped if a ‘new’ HV BPA if replacement is performed.

ECU Upgrade Procedure:

To correct this condition, the ECU should be reprogrammed using the KDS  download, as described in this bulletin.

A5. For all 2018-2019 MY Soul EV vehicles: Dealers will update the vehicle’s battery management system with new software that will detect an abnormal battery cell voltage condition before an electrical short circuit occurs. Following installation of the new software, if the abnormal battery cell voltage is detected by the vehicle’s battery management system, the EV warning light will illuminate, charging capacity will be limited to 80% and the vehicle will be placed into a reduced-power “limp home” mode. If this occurs, the dealer will replace the high voltage battery with a new one. Customers may experience the following symptoms/warnings indicating this concern: Incomplete high voltage battery charging, loss/fluctuating vehicle range, and/or illumination of the EV warning light.
