  1. CHECK DATA MONITOR (Charging Current Duty from Charger/Time Cycle of Charging Current Duty from Charger)  .
    1. Using the Subaru Select Monitor, display the following items in the [Data Monitor] of [Plug-in Battery Charger]. Ref. to PLUG-IN BATTERY CHARGER (DIAGNOSTICS)>DATA MONITOR .
      • Charging Current Duty from Charger
      • Time Cycle of Charging Current Duty from Charger
      Item name Item explanation Display range Standard
      Charging Current Duty from Charger Indicates the charging current command value. 0.00 - 100.00% 5 - 39%: Charging connector connected 0%: EVSE (charging equipment) system not connected, or power not available
      Time Cycle of Charging Current Duty from Charger Indicates the time for 1 CPLT cycle. 0 - 65535 μs 951 - 1049 μs: CPLT oscillating
