DTC P0A80-123: Replace Hybrid Battery Pack [10/2013 - ]: Description
WARNING: This page is about a different variant/trim than selected.
- The HV battery uses nickel metal-hydride batteries and does not require external charging. The power management control ECU controls the SOC (state of charge) of the HV battery at a constant level during driving. The HV battery is composed of 34 modules, and each module consists of six 1.2 V cells in series. The battery voltage sensor monitors battery block Voltage at 17 locations. Each battery block is composed of 2 modules in a set.
DTC No. INF Code DTC Detection Condition Trouble Area P0A80 123 Difference in voltage between battery blocks is larger than the standard (2 trip detection) - HV battery
- Battery voltage sensor
RELATED DATA LISTDTC No. Data List P0A80-123 - Battery Block Vol - V01 to V17
- State of Charge (All Bat)
HINT:
- This DTC can be stored after clearing DTCs and driving the vehicle for approximately 10 minutes. (As 2 trip detection logic is used, check for DTCs including pending DTCs.)
- DTC P0A80-123 is stored when a malfunction is detected in the HV battery or battery voltage sensor. If the HV supply battery is malfunctioning, the malfunction may not be reproduced when the condition of the HV supply battery changes due to difference in driving load (amperage), battery SOC and battery temperature. Therefore, use the freeze frame data when performing a repair.
- When the HV battery is malfunctioning:
- - Voltage of one or a few of the battery blocks has dropped. (voltage difference from that of the next block is 1 V or more)
- - Voltage of all battery blocks is output randomly with no certain pattern.
- When the battery voltage sensor is malfunctioning:
- - Differences in battery block Voltages have a certain pattern.
- When the HV battery is malfunctioning:
