Basic TroubleshootingBasic Inspection ProcedureMeasuring Condition of Electronic Parts' ResistanceThe measured resistance at high temperature after vehicle running may be high or low.
DescriptionThe HCU (Hybrid Control Unit) controls whole hybrid systems and is connected with each control modules (ECM, TCM, MCU, BMS ECU etc.) by CAN interface.
Inspection1.Turn the ignition switch OFF.2.Disconnect the evaporator temperature sensor connector.3.Measure the resistance between terminal "+" and "-" of the evaporator temperature sensor.Specification Evaporator core temperature [°C (°F)] Resistance [KΩ]
Removal1.Disconnect the negative (-) battery terminal.2.Remove the rear bumper.(Refer to Body - "Rear Bumper")3.Remove the rear corner radar unit (A) after loosening the mounting nuts. • Take care not to separate the bracket from rear bumper when removing the rear corner radar sensor.
