HYBRID CONTROL SYSTEM, Diagnostic DTC:P06A4-209, P06A5-210

DTC Code DTC Name
P06A4-209 Sensor Reference Voltage "D" Circuit Low
P06A5-210 Sensor Reference Voltage "D" Circuit High

DESCRIPTION

The power management control ECU (HV CPU) monitors voltage of 5 V power supply (VC) used for the sensors. If the power management control ECU (HV CPU) detects a malfunction, it will set a DTC.

DTC No. INF Code DTC Detection Condition Trouble Area
P06A4 209 VC power-supply voltage is lower than 4.2 V Power management control ECU
P06A5 210 VC power-supply voltage is higher than 5.8 V Power management control ECU
