This bulletin applies to 2017-2018 Kia Niro DE P/HEV vehicles. The MIL may be on, with a stored DTC P060500 (internal control module read only memory/ROM error). This condition may be difficult to duplicate. There may be insufficient contact between the GC101 ground and the vehicle body. Improve the ground connection by cleaning the area of contact of the GC101 bolt to bare metal and by adding an external tooth lock washer between the ground wire and body. Use wire harness repair kit II (TKL04-A0000) and star washer TKL04-A5001 or equivalent.
