NOTE:  Before you troubleshoot, review the general troubleshooting information .

DTC (Electric Powertrain)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   -3. Turn the vehicle to the OFF (LOCK) mode.

   -4. Turn the vehicle to the ON mode.

   -5. Check for Pending or Confirmed DTCs with the HDS.

   Is DTC P06B1 indicated?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

2. Determine possible failure area (battery current sensor, others)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Remove the service plug and the IPU cover .

   -3. Remove the IPU and the IPU case .

   -4. Disconnect the following connector.

   Battery current sensor 4P connector

   -5. Reinstall the IPU .

   -6. Do the 12 volt battery terminal reconnection procedure .

   -7. Turn the vehicle to the ON mode.

   -8. Clear the DTC with the HDS.

   -9. Check for Pending or Confirmed DTCs with the HDS.

   Is DTC P06B1 indicated?

   YES 

   Go to step 3.

   NO 

   Replace the battery current sensor .

3. Shorted wire check (VCCISOC line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Do the 12 volt battery terminal disconnection procedure .

   -3. Disconnect the following connector.

   Battery condition monitor module connector E (32P)

   -4. Measure the resistance between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Battery current sensor 4P connector: disconnected
   	Battery condition monitor module connector E (32P): disconnected
   Test point 1	Battery condition monitor module connector E (32P) No. 28
   Test point 2	Body ground

   Is there 1 MΩ or more?

   YES 

   Replace the battery condition monitor module .

   NO 

   Repair a short in the VCCISOC wire between the battery current sensor and the battery condition monitor module (E28).
