| 18-092-15 | 2019-05-20. Service bulletin. Flash: Diagnostic And System Improvements This bulletin involves diagnosis and selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software or if necessary replacing the PCM based on the DIAGNOSIS. This new software once reprogrammed in the PCM will prevent the need to replace the PCM when the Diagnostic Trouble Codes (DTCs) listed below occur as a pair. A small number of customers may experience one or more of the symptoms/conditions listed below or a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the Technician may find the following Diagnostic Trouble Code (DTCs): Upon further investigation the Technician may find that any of the following Diagnostic Trouble Codes have been set. If any of the following DTC's have been set perform the Diagnosis. ? U0140 - Lost Communication With Body Control Module. Attempting to clear this DTC will be unsuccessful. ? P0032 - O2 Sensor 1/1 Heater Circuit High. ? P0038 - O2 Sensor 1/2 Heater Circuit High. ? P0052 - O2 Sensor 2/1 Heater Circuit High. ? P0058 - O2 Sensor 2/2 Heater Circuit High. ? P0031 - O2 Sensor 1/1 Heater Circuit Low. ? P0037 - O2 Sensor 1/2 Heater Circuit Low. ? P0051 - O2 Sensor 2/1 Heater Circuit Low. ? P0057 - O2 Sensor 2/2 Heater Circuit Low. ?
