P0A80
DTC P0A80-123 Replace Hybrid Battery PackDESCRIPTION
DTC Detection Condition:
The hybrid vehicle control ECU controls the SOC (state of charge) of the HV battery at a constant level while driving. The HV battery is composed of 40 modules, and each module consists of six 1.2 V cells in series. The battery smart unit monitors battery block voltage at 20 locations. Each battery block is composed of 2 modules in a set.
HINT: P0A80-123 cannot be set unless the vehicle is driven for approximately 10 minutes after clearing the DTCs. (Turn the power switch off and perform a road test again after the first road test because this DTC is a 2 trip detection DTC.)
MONITOR DESCRIPTION
Monitor Strategy:
Typical Enabling Conditions:
Typical Malfunction Thresholds:
Component Operating Range:
The battery smart unit, which monitors the voltage of the battery blocks, determines that malfunction has occurred if a voltage difference between the battery blocks exceeds the standard. When the malfunction detection condition is satisfied, the HV control ECU illuminates the MIL and set a DTC.
