DTC P0A9D (49), P0AC7 (51), P0ACC (53), P0AEA (121), P0BC4 (162)

NOTE:  Before you troubleshoot, review the How to Troubleshoot the Electric Powertrain and Electric Powertrain Service Precaution .

DTC (Electric Powertrain)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   -3. Check the parameter (s) of the corresponding DTC below with the HDS.

   Signal	Threshold		Current conditions
   	Values	Unit	Values	Unit
   HV Battery Module Temperature Sensor1 Voltage	Less than 0.08	V
   HV Battery Module Temperature Sensor2 Voltage	Less than 0.08	V
   HV Battery Module Temperature Sensor3 Voltage	Less than 0.08	V
   HV Battery Module Temperature Sensor4 Voltage	Less than 0.08	V
   HV Battery Module Temperature Sensor5 Voltage	Less than 0.08	V

   Do the current condition (s) match the threshold?

   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 (TBATT line, battery condition monitor module)

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

   -2. Remove the service plug .

   -3. Remove the IPU cover .

   -4. Disconnect the following connector (s).

   Battery condition monitor module connector F (12P)

   -5. Check for continuity between appropriate DTC's test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Battery condition monitor module connector F (12P): disconnected

   DTC	Test point 1	Test point 2
   P0A9D (TBATT1)	Battery condition monitor module connector F (12P) No. 1	Body ground
   P0AC7 (TBATT2)	Battery condition monitor module connector F (12P) No. 7
   P0ACC (TBATT3)	Battery condition monitor module connector F (12P) No. 2
   P0AEA (TBATT4)	Battery condition monitor module connector F (12P) No. 8
   P0BC4 (TBATT5)	Battery condition monitor module connector F (12P) No. 3

   Is there continuity?

   YES 

   Go to step 3.

   NO 

   Replace the battery condition monitor module .

3. Shorted wire check (TBATT line)

   -1. Remove the IPU .

   -2. Remove the IPU case .

   -3. Disconnect the following connector.

   DTC P0A9D, P0AC7, P0ACC: High voltage battery module temperature sensor connector A (6P)

   DTC P0AEA, P0BC4: High voltage battery module temperature sensor connector B (4P)

   -4. Check for continuity between appropriate DTC's test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	DTC P0A9D, P0AC7, P0ACC: High voltage battery module temperature sensor connector A (6P) : disconnected
   	DTC P0AEA, P0BC4: High voltage battery module temperature sensor connector B (4P) : disconnected
   	Battery condition monitor module connector F (12P): disconnected

   DTC	Test point 1	Test point 2
   P0A9D (TBATT1)	Battery condition monitor module connector F (12P) No. 1	IPU ground (G801)
   P0AC7 (TBATT2)	Battery condition monitor module connector F (12P) No. 7
   P0ACC (TBATT3)	Battery condition monitor module connector F (12P) No. 2
   P0AEA (TBATT4)	Battery condition monitor module connector F (12P) No. 8
   P0BC4 (TBATT5)	Battery condition monitor module connector F (12P) No. 3

   Is there continuity?

   YES 

   Repair a short in the TBATT wire between the battery condition monitor module and the high voltage battery module temperature sensor.

   NO 

   Failure in the following high voltage battery module temperature sensor. Replace the battery pack .
