DIAGNOSIS PROCEDURE

STEP 1. Quick charger check
danger When servicing the high voltage system parts, always shut off the high voltage by removing the service plug (refer to ).
danger Be sure to wear the specified protective equipment when removing the service plug.
Check if the quick charger can be removed from the quick charging connection.

Q. Is the check result normal?
Go to Step 2.
Check the quick charger. Then go to Step 3.

STEP 2. Measure the high voltage at G-10 quick charging connection.
danger When servicing the high voltage system parts, always wear the protective equipment or armour to measure the high voltage (refer to ).
danger Be sure to wear the specified protective equipment when removing the service plug.
(1)Before removing the quick charger, install the service plug.
(2)Set the electric motor switch from the "LOCK" (OFF) position to the "ON" position.
(3)Using a high voltage multimeter, measure the high voltage between the G-10 quick charging connection terminal No. 1 and No. 2.
OK: 0 V

Q. Is the check result normal?
Go to Step 3.
Replace the main battery assembly. (Refer to .) Then go to Step 3.

STEP 3. Diagnosis code recheck
Check again if the diagnosis code is set to the EV-ECU.
(1)Erase the stored diagnosis code.
(2)Set the electric motor switch from the "LOCK" (OFF) position to the "ON" position.
(3)Check if the diagnosis code is set.
