DESCRIPTION A battery
current sensor is installed to the positive (+) terminal 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 hybrid
vehicle control ECU. The hybrid vehicle 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.  |

P0ABF00 | - | MONITOR DESCRIPTION
The
hybrid vehicle control ECU detects malfunctions of the battery current
sensor by monitoring motor and generator torque. If the hybrid vehicle
control ECU detects a battery current sensor malfunction, the hybrid
vehicle control ECU will illuminate the MIL and store a DTC. MONITOR STRATEGY |

HINT:
- After repair has been completed, clear the DTC and then check that the
vehicle has returned to normal by performing the following All Readiness
check procedure.
Click here 
- When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the power switch off and wait for 2 minutes or more.
- Turn the power switch on (IG) and turn the Techstream on.
- Drive the vehicle for approximately 10 minutes according to the freeze
frame data items "Vehicle Speed", "Accelerator Position", "Hybrid
Battery Current", "Motor Torque" and "Generator Torque". [*1]
HINT:
[*1] : Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.
- Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
