Enable Conditions

Condition
Vehicle	ON mode

Malfunction Threshold

One of the following conditions is occurs:

Maximum cell voltage is 4.5 V or more for at least 2.74 seconds.
Maximum cell voltage is 4.42 V or more for at least 4.41 seconds.
Maximum cell voltage is 4.28 V or more for at least 5.78 seconds.

Possible Cause

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

Battery pack internal failure
Powertrain control module (PCM) internal circuit failure
Power control unit (PCU) internal circuit failure
Battery condition monitor module internal circuit failure

Confirmation Procedure

Operating Condition

Turn the vehicle to the ON mode, and wait for at least 10 seconds.

With the HDS

None.

Diagnosis Details

Conditions for setting the DTC

When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the battery condition monitor module memory.

Conditions for clearing the DTC

The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool clear command or the battery condition monitor module reset.
