DTC P0D27: BATT. Charger Input Low Voltage
DTC P0D28: BATT. Charger Input High Voltage
 
 
 
 
TROUBLE JUDGMENT
Check Condition
  • While the on board charger is allowed to charge from PHEV-ECU.
Judgment Criterion
  • <DTC P0D27>
    • The AC input voltage is low.
  • <DTC P0D28>
    • The AC input voltage is high.
 
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • The charge is stopped.
 
 
PROBABLE CAUSES
  • The AC power supply (at the supply side) is abnormal.
  • The charging cable is failed.
  • Open circuit or harness damage in normal charging high voltage system circuit or loose connector contact.
  • The on board charger/DC-DC converter is failed.
 
 
 
 
DIAGNOSIS
Required Special Tools
  • MB991223: Wiring harness set
  • MB992006: Extra fine probe
dangerWhen high voltage system components are served, be sure to pull service plugs to shut down high voltage (Refer to ).
dangerWhen pulling service plugs, wear the specified protective equipment (Refer to ).
STEP 1. After charging with the normal power supply facility, using scan tool (M.U.T.-IIISE), check whether the DTC is set.
Is the DTC set?
Go to Step 2.
Check the AC power supply usage conditions used by the users.
 
STEP 2. Check charging cable itself
  • Check charging cable (Refer to ).
Is the check result normal?
Go to Step 3.
Replace the charging cable.
 
STEP 3. Check of open circuit and damage in COLD line and HOT line between on board charger/DC-DC converter connector and normal charging connector.
dangerWhen high voltage system components are served, be sure to pull service plugs to shut down high voltage before serving (Refer to ).
dangerWhen pulling service plugs, wear the specified protective equipment (Refer to ).
Is the check result normal?
Go to Step 4.
Repair the connector(s) or wiring harness.
 
STEP 4. Using scan tool (M.U.T.-IIISE), check on board charger/DC-DC converter data list.
  • Data List Reference Table (Refer to ).
    • Item No.29: Input voltage
Is the check result normal?
Go to Step 5.
Replace the on board charger/DC-DC converter (Refer to ).
 
STEP 5. Using scan tool (M.U.T.-IIISE), check whether the DTC is set again.
Is the DTC set?
Replace the on board charger/DC-DC converter (Refer to ).
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
