DESCRIPTION
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: P3011-123 to P3029-123 cannot be set unless the vehicle is driven for approximately 10 minutes after clearing the DTCs.
MONITOR DESCRIPTION
Monitor Strategy:
Typical Enabling Conditions:
Typical Malfunction Thresholds:
Component Operating Range:
If there is an abnormal internal resistance or electromotive voltage in the battery blocks, the battery smart unit determines that a malfunction has occurred. When the malfunction detection condition is satisfied, the HV control ECU will illuminate the MIL and set a DTC.
