DTC P0A7D: Hybrid Battery Pack State Of Charge Low: Trouble Symptom

WARNING: This page is about a different car, the 2015 Subaru XV Crosstrek. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Before performing diagnosis, refer to "CAUTION" in "General Description". < Ref. to CAUTION , General Description.>
DTC PROCEDURE

Step Check Yes No
1 CHECK FREEZE FRAME DATA. 
Using the Subaru Select Monitor, confirm the value of «High Voltage Battery Amperage» in the freeze frame data of battery energy control system. < Ref. to BATTERY ENERGY CONTROL SYSTEM , OPERATION, Freeze Frame Data Display.>
Is the value 1A (discharge) or more? Go to step 2  . Replace the high voltage battery. < Ref. to HIGH VOLTAGE BATTERY .>
2 CHECK DTC. 
Using the Subaru Select Monitor, read DTCs of the following system.
  • Hybrid powertrain control system < Ref. to HYBRID POWERTRAIN CONTROL SYSTEM , OPERATION, Read Diagnostic Trouble Code (DTC).>
  • Drive motor control system < Ref. to DRIVE MOTOR CONTROL SYSTEM , OPERATION, Read Diagnostic Trouble Code (DTC).>
  • CVT System < Ref. to appropriate OPERATION, Read Diagnostic Trouble Code (DTC) in CVT Diagnostics (TR58A) article.>
Are any other DTCs detected? (current malfunction) Perform the diagnosis according to DTC. < Ref. to LIST , List of Diagnostic Trouble Code (DTC).> < Ref. to appropriate LIST, List of Diagnostic Trouble Code (DTC) in CVT Diagnostics (TR58A) article.> Go to step 3  .
3 CHECK CURRENT DATA. 
  1. Turn the ignition to OFF.
  2. Start the engine.
  3. Check illumination of "Hybrid READY indicator light" in the meter.
Is the indicator illuminating? Go to step 4  . Replace the HPCM. < Ref. to HYBRID POWERTRAIN CONTROL MODULE .>
4 CHECK CURRENT DATA. 
  1. Drive approximately 2 km (1.2 miles) at a speed of 30 km/h (18.6 MPH) or more.
  2. Using the Subaru Select Monitor, confirm the current data of battery energy control system, the value of «High Voltage Battery SOC». < Ref. to BATTERY ENERGY CONTROL SYSTEM , OPERATION, Read Current Data.>
Is the value 6% or more? Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.
NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.
Replace the high voltage battery. < Ref. to HIGH VOLTAGE BATTERY .>
