HYBRID / BATTERY CONTROL: HYBRID BATTERY SYSTEM: P3011-123-P3019-123,P3020-123-P3025-123: Battery Block 1 Becomes Weak
P3025-123 - Battery Block 15 Becomes Weak

DESCRIPTION

- Refer to the Description for DTC P0A9C-123 P0A9C.

HINT
P3011-123 and P3025-123 will not be set unless the vehicle is driven for approximately 10 minutes after clearing the DTCs.

MONITOR DESCRIPTION

If there is an abnormal internal resistance or voltage in the battery blocks, the battery smart unit determines that a malfunction has occurred. When the malfunction detection condition is satisfied, the power management control ECU (HV CPU) will illuminate the MIL and set a DTC.
