HYBRID CONTROL SYSTEM, Diagnostic DTC:P0AC0-817

DTC Code DTC Name
P0AC0-817 Hybrid Battery Pack Current Sensor Circuit Range / Performance

DESCRIPTION

A battery current sensor is installed to the positive (+) cable side of the HV battery and detects current flowing from the HV battery. The battery current sensor outputs voltage, which changes between 0 and 5 V according to the detected amperage, to the IB terminal of the battery voltage sensor. The battery voltage sensor sends signals to the power management control ECU. The power management control ECU determines the charging and discharging amount of the HV battery based on the received signals and calculates the SOC of the HV battery through the accumulated amperage.

Tech Tips

After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.


  1. Drive the vehicle for approximately 10 minutes according to the freeze frame data items "Vehicle Spd", "Accelerator Degree", "Power Resource IB", "M(MG2) Trq Exec Val" and "G(MG1) Trq Exec Val".

PROCEDURE


  1. CHECK DTC OUTPUT (HYBRID CONTROL)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
