Code C151D Description

When the localization sequence is not completed successfully. Must fail multiple vehicle Tire Pressure Monitor (TPM) Sensor locate processes if localization fails due to a TPM sensor, or if the Radio Frequency Hub (RF-Hub) Module is new and has never attempted localization. If missing TPM Sensors are present on first drive, this Diagnostic Trouble Code (DTC) will set to show that the TPM Sensor location cannot be determined/guaranteed (cannot revert to last known good locations).
