SUBJECT: DTC B2327 / B2328- Diagnosis and Repair 		
Procedure
REVISED: 06/22/17
INTRODUCTION:
This bulletin provides revised diagnostic and repair procedures to address DTC B2327 for the
Subaru Rear Vehicle Detection (SRVD), Blind-Spot Detection (BSD) and Rear Cross Traffic
Alert (RCTA) system on the applicable models listed above. Under very specific (rare) conditions,
the radar function of the SRVD system may experience a communication error and cause the SRVD
warning lamp to illuminate. In addition, under certain highway driving conditions, an improper
signal calculation by the system may cause a Cancel Code B2328 to set which will also cause the
SRVD warning lamp to illuminate.
NOTE: When the SRVD warning lamp is illuminated, the Rear Cross Traffic Alert (RCTA) and
Blind-Spot Detection (BSD) features are also inoperative.
PRODUCTION CHANGE INFORMATION:
New SRVD units with updated logic were incorporated into production starting with the following
VINs:
Vehicle / Model

WRX
Starting VIN

IMPORTANT NOTES:
• When performing Step 4 from the B2328 table above, the diagnosis must be performed
individually for BOTH SRVD units.
• If the diagnosis determines both SRVD units are faulty (NG), replace both with the new part
number 87611VA020.
• If only one SRVD unit is determined to be NG, replace it with the same part number of the
non-faulty (OK) SRVD unit so both units are the same part number.

IMPORTANT NOTES:
• If the bulletin diagnostic steps recommend use of the Service Manual, use the applicable Service
Manual along with applicable claim coding found in the LTG based on the findings.
• If the diagnostic steps lead you to replacement of both SRVD units, use coding below.
