Diagnostic procedure:

  1. Using the Subaru Select Monitor, perform the clear memory of [P-HEV Hybrid Powertrain Control]. Ref. to COMMON (DIAG)>CLEAR MEMORY .
  2. Turn to IG OFF, and wait for two minutes or more.
  3. Using the Subaru Select Monitor, read the DTC of [P-HEV Hybrid Powertrain Control] to check that there is no DTC displayed. Ref. to P-HEV HYBRID POWERTRAIN CONTROL (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
    NOTE: If the DTC is displayed on the screen, the trouble is still present. Perform the diagnosis for the displayed DTCs. After solving the DTC, repeat from step  1.
  4. Set the wheel stoppers to the tires, and apply the parking brake.
  5. With the vehicle stopped, shift to P position, turn to READY ON, and wait for one minute or more.
  6. Turn the air conditioner to ON (temperature setting Lo/COOL MAX, and air flow maximum).
  7. Shift to D position while depressing the brake pedal without depressing the accelerator pedal, and wait for five minutes.
    • When DTC P0AA649 is output at this point, if step 9) is performed continuously within the same trip, identification of the insulation resistance decrease section is performed, and P1C7C49, P1C7D49, P1C7E49, P1C7F49 or P33CF49 is added and stored.
    • When DTC is not output, go to step 8.
  8. Drive the vehicle approximately five minutes while referring to [Vehicle Speed], [Shift Position], [Accel. Opening Angle], [Engine Speed], [Coolant Temp], [Master Cylinder Control Torque], [Inverter Coolant Water Temperature], [Generator Inverter Calculated Temperature] and [Motor Inverter Temperature] of the freeze frame data.

    (When the freeze frame data [Vehicle Speed] is less than 10 km/h (6.2 MPH), drive the vehicle at 10 km/h (6.2 MPH) or more.)

    • When DTC P0AA649 is output at this point, if step 9) is performed continuously within the same trip, identification of the insulation resistance decrease section is performed, and P1C7C49, P1C7D49, P1C7E49, P1C7F49 or P33CF49 is added and stored.
    • When DTC P0AA649 is output, continuously complete the step 9) immediately.
    • When DTC is not output, go to step 10.
  9. After waiting for one minute or more with READY ON, P position, the vehicle stopped, and the air conditioner ON (temperature Lo/COOL MAX, air flow maximum), turn to READY OFF and wait for two minutes or more.
  10. Turn to IG OFF, connect Electric vehicle charger cable assembly, and charge it for three minutes or more.
    • When charging cannot last for three minutes while DTC is not output, decrease SOC and perform step 10) again.
    • When DTC P0AA649 is output at this point, identification of the insulation resistance decrease section is performed, and P1C7D49, P1CF749 or P33CF49 is added and stored.
  11. Using the Subaru Select Monitor, read the DTC of [P-HEV Hybrid Powertrain Control] to check that there is no DTC displayed. Ref. to P-HEV HYBRID POWERTRAIN CONTROL (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
    NOTE: If the DTC is displayed on the screen, the trouble is still present. Perform the diagnosis for the displayed DTCs.
