My 2014 jk abs / traction control lights came on .. few days later check engine light came on . Took it to mechanic , replaced right rear sensor and did some other maintenance . Took it home and was all good .. next day drove to work check engine light comes on .. while sitting in parking lot I did the key 3x trick to see code .. runs test and says done then check engine light blinks 10x and goes off ? So now I’m thinking I fixed it .. after work I bring it back to mechanic and he checks for codes ... nothing .. next day check engine light comes back on and I do same 3x key trick and again blinks 10x and shuts off .. what could this be ? Anyone every hear of this ?,I checked every forum before I bothered everyone with a stupid question and couldn’t find anything ..
