| Diagnostic Aids: | The presence of this DTC may indicate that the vehicle is operating in derate mode and may experience a loss of power. After repair, the vehicle may still display a system warning message. Drive the vehicle, while carrying out the appropriate drive cycle procedure, until the system warning message has cleared from the instrument cluster message center. Refer to DRIVE CYCLES
for additional information. The reductant level sensor and reductant temperature sensor share a common ground. An open or short to voltage in this ground sets DTCs for both sensors. |
