Summary

Certain GV60 (JW1 EV) vehicles may exhibit a condition where DTC P1AA900 becomes active after charging. The Battery Management System (BMS) software logic could cause an HV battery cell voltage to be misread under specific conditions resulting in a false-positive DTC P1AA900, MIL on, and 80% maximum HV battery charge limit. There is no other effect on the vehicle and all systems remain operational. Regardless of whether the vehicle has an active DTC P1AA900 or not, follow the procedure in this TSB to update the software for the Battery Management System (BMS).

Owners of these vehicles have filed 7 complaints in the fuel system category.
