DTC P2715 (Pressure Control Solenoid “D” Stuck On) Diagnosis
INTRODUCTION:
This Service Information Bulletin announces the diagnostic procedures to be followed when DTC
P2715 (Pressure Control Solenoid “D” Stuck On) is detected by the Transmission Control Module
(TCM). In some rare cases DTC P2715 may be inaccurately detected when the Vehicle Dynamics
Control (VDC) has detected faults during fail-safe mode. When self-diagnosis is conducted while
the lock-up control is restricted during a VDC triggered fail safe mode, the DTC can be inaccurately
detected by the TCM. If DTC P2715 is found to be stored in the TCM, follow the diagnostic
procedures outlined below.
SERVICE PROCEDURE:
REMINDER: ALWAYS check other control modules for related DTCs.
STEP 1: Using Subaru Select Monitor, perform an all-system DTC check. Confirm DTC P2715 is
stored in the TCM.
STEP 2: Read the freeze frame data of DTC P2715. Is the “Lock Up Duty Ratio” less than 95.2%?
NO – The CVT Pressure Control Solenoid is likely to be the fault source. Confirm the CVT
Pressure Control Solenoid status by performing the diagnostic procedures outlined in the
applicable Service Manual. Clear the fault memory when repairs are completed.
YES – P2715 has been inaccurately detected. Perform the diagnosis and repair for chassis
fault codes (C-Type) stored in the VDC control module by performing the diagnostic
procedures outlined in the applicable Service Manual. Clear the fault memory when repairs
are completed.
NOTE: Avoid following the trouble tree diagnosis for code C1431 when diagnosing P2715
misdetection.
CAUTION: VEHICLE SERVICING PERFORMED BY UNTRAINED PERSONS COULD
RESULT IN SERIOUS INJURY TO THOSE PERSONS OR TO OTHERS.
Subaru Service Bulletins are intended for use by professional technicians ONLY. They
are written to inform those technicians of conditions that may occur in some vehicles,
or to provide information that could assist in the proper servicing of the vehicle. Properly
trained technicians have the equipment, tools, safety instructions, and know-how to
do the job correctly and safely. If a condition is described, DO NOT assume that this
Service Bulletin applies to your vehicle, or that your vehicle will have that condition.
