Subaru Legacy BN/BS (2015-2019) Service Manual / Blind spot detection rear cross traffic alert (diagnostics) / List of cancel code list

Code	Item	Contents of diagnosis
B2320	REAR RADAR LOW VOLTAGE (LESS THAN 9 V)	Temporarily stops because the voltage supplied to radar drops to or below 9 V. Returns to normal when the voltage becomes normal.
B2321	REAR RADAR HIGH VOLTAGE (MORE THAN 16 V)	Temporarily stops because the voltage supplied to radar rises to or above 16 V. Returns to normal when the voltage becomes normal.
B2328	REAR RADAR INTERNAL FAILURE (RADAR MISALIGNMENT)	Deviation of the radar axis prevents normal detection. Returns to normal when the radar axis becomes normal. When B2328 is frequently detected, perform “Diagnostic Procedure with Cancel Code”. Diagnostic Procedure with Cancel Code > DTC B2328 REAR RADAR INTERNAL FAILURE (RADAR MISALIGNMENT)
B2340	RADAR ASSY B&S OUT OF OPERATION TEMPERATURE RANGE	Temporarily stops because the temperature is outside the operative range (−40°C (−40°F) — 85°C (185°F)). Returns to normal when the ambient temperature falls within the operative range.
B2341	RADAR ASSY B&S DEGRADATION OF DETECTING PERFORMANCE	Temporarily stops because some obstacles blocked radar waves of the back and side radar. Returns to normal when the transmission and reception of radar signals becomes normal.
