The power management control ECU (HV CPU) uses signals from the coolant temperature sensor to check the effectiveness of the inverter cooling system. If necessary, the power management control ECU (HV CPU) will limit inverter output to help prevent inverter overheating.
請原廠接電腦看到底是哪個部件過熱 The power management control ECU (HV CPU) records inappropriate operations performed by the driver and the number of abnormal conditions that have been input to the ECU as operation history data. (a) Connect the Techstream to the DLC3. (b) Turn the power switch on (IG). (c) Turn the Techstream on. (d) Enter the following menus: Powertrain / Hybrid Control / Data List. (e) Enter the menu to view the number of inappropriate operations or controls that have been performed.
Inappropriate operation and history data:
MG2 Temp High MG2 temperature exceeded 323.6°F (162°C)
MG1 Temp High MG1 temperature exceeded 334.4°F (168°C)
MG2 (Motor) Inv Temp High Motor inverter temperature rose and HV system overheat was indicated
MG1 (Generator) Inv Temp High Generator inverter temperature rose and HV system overheat was indicated
Resister Over Heat System main resistor overheated
Coolant Heating HV coolant temperature exceeded 149°F (65°C)
Converter Heating Boost converter temperature rose and HV system overheat was indicated
