## NHTSA's summary

N63 Misfire Faults Stored in DME Fault Memory \- Diagnostic Hints. Please follow the procedures below when diagnosing a Service Engine Soon lamp, illuminated with misfire faults, stored in the DME fault memory. Always diagnose the vehicle using the misfire test plan \(AT1214\_DI8MISFIRE \- Misfiring detection\) first. After completion of this test plan, repair the vehicle as directed before performing any other suggested engine or fuel system\-related test plans, e.g., AT1214\_DI8KHDR \- High\-pressure fuel system, AT1214\_DI\_GEM \- Mixture adaptation, etc. Failure to diagnose the engine or fuel system issue in this order could cause incorrect diagnosis and repeat repair attempts.
