we checked the vehicle we found the fault code 2771 count was more than 2000 times and due to 2771 3583 code was also active and inactive so the vehicle pickup was dropped then we checked the nox sensor coupler current then we found 24v and can high and can low 2.9v but here need can high 3v and can low 2v so this problem was coming again and again. then we checked the current near ecm we found correct voltage. then we opened the ecm J1 coupler and cleaned and checked the current the got there can high 3v and can low 2v the the problem got solved
