Blind Spot Detection/Rear Cross Traffic Alert System DTCS

BLIND SPOT DETECTION/REAR CROSS TRAFFIC ALERT SYSTEM DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION

Code Item Contents of diagnosis
B2320 Rear RADAR Low Voltage (less than 9V) Temporarily stops because the voltage supplied to radar sensor drops to or below 9 V. Returns to normal when the voltage becomes normal.
B2321 Rear RADAR High Voltage (more than 16V) Temporarily stops because the voltage supplied to radar sensor 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 sensor axis prevents normal detection. Returns to normal when the radar axis becomes normal.
When B2328 is frequently detected, perform "Diagnostic Procedure with Cancel Code". Ref. to BLIND SPOT DETECTION/REAR CROSS TRAFFIC ALERT (DIAGNOSTICS)>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 Rear RADAR degradation of detecting performance Temporarily stops because some obstacles blocked radar sensor waves. Returns to normal when the transmission and reception of radar signals becomes normal.
