| I have a 2018 All American no power and warning lights.I get a 1347 , 157 , 272 , 553 and a 3748. The first two are active and the last two are in active except the 553 has set things off a 11 times. I am hopping a nox sensor can cause all these codes |

| Before you do ANYTHING, verify all the batteries pass a load test, and all connections, grounds, etc are clean and tight. Been burned by this before on these AA crapboxes, one weak battery causing one code after another after another. |

QSOL fault analyzer states go after code 272 first ( this will cause 553 code)
then go after your nox code 3748 only three step code check for power and ground and 60 ohms on data link
other two codes states 157 and 1347 not applicable to esn I tried a 2015,2019 and 2021 ESN's all state not applicable |
