PROCEDURE

  1. CHECK DTC OUTPUT (DTC P0A1F-123 IS OUTPUT) Connect the Techstream to the DLC3. Turn the power switch on (IG). Select the following menu items: Powertrain / Hybrid Control / Trouble Codes. Check if DTCs are output. Result DTC P0A1F-123 is output. YES --> GO TO INSPECTION PROCEDURE RELEVANT TO OUTPUT DTC NO: Go to next step
  2. CHECK BATTERY SMART UNIT Ensure the safety of the areas in front and rear of the vehicle. Connect the Techstream to the DLC3. Turn the power switch on (READY). Select the following menu items: Powertrain / Hybrid Control / Data List / Battery Block Vol -V01 to V20. Fully warm up the engine and turn the air conditioning off. Firmly depress the brake pedal with your left foot. Move the shift lever to the D position. Record each battery block voltage from the data list (Battery Block Vol -V01 to V20) while fully depressing the accelerator pedal. Compare the battery block voltages (Battery Block Vol -V01 to V20) between the even and odd number groups in each combination shown in the table below. Even number group Odd number group Battery block voltages to be compared Battery Block Vol-V01 Battery Block Vol-V02 Battery Block Vol-V01 - Battery Block Vol-V02 Battery Block Vol-V03 Battery Block Vol-V04 Battery Block Vol-V03 - Battery Block Vol-V04 Battery Block Vol-V05 Battery Block Vol-V06 Battery Block Vol-V05 - Battery Block Vol-V06 Battery Block Vol-V07 Battery Block Vol-V08 Battery Block Vol-V07 - Battery Block Vol-V08 Battery Block Vol-V09 Battery Block Vol-V10 Battery Block Vol-V09 - Battery Block Vol-V10 Battery Block Vol-V11 Battery Block Vol-V12 Battery Block Vol-V11 - Battery Block Vol-V12 Battery Block Vol-V13 Battery Block Vol-V14 Battery Block Vol-V13 - Battery Block Vol-V14 Battery Block Vol-V15 Battery Block Vol-V16 Battery Block Vol-V15 - Battery Block Vol-V16 Battery Block Vol-V17 Battery Block Vol-V18 Battery Block Vol-V17 - Battery Block Vol-V18 Battery Block Vol-V19 Battery Block Vol-V20 Battery Block Vol-V19 - Battery Block Vol-V20 Check if the difference in voltage of each combination is 0.3 V or more. Result Result Proceed to Difference in voltage of each combination is less than 0.3 V. A Difference in voltage of each combination is 0.3 V or more. B HINT: Difference in voltage of each combination may be 0.3 V or more due to a battery smart unit internal error. B --> See step 4 A --> See step 3
  3. REPLACE HV BATTERY. Refer to «COMPONENTS»(ref-387094-S20340730302011022400000)
  4. REPLACE BATTERY SMART UNIT. Refer to «COMPONENTS»(ref-387094-S42447307232011022400000)

Scheme 818: DESCRIPTION
Scheme 818: DESCRIPTION
  1. The hybrid vehicle control ECU controls the SOC (state of charge) of the HV battery at a constant level while driving. The HV battery is composed of 40 modules, and each module consists of six 1.2 V cells in series. The battery smart unit monitors battery block voltage at 20 locations. Each battery block is composed of 2 modules in a set. DTC No. DTC Detection Condition Trouble Area P0A80-123 Difference in voltage between battery blocks is larger than the standard (2 trip detection) HV battery Battery smart unit HINT: P0A80-123 cannot be set unless the vehicle is driven for approximately 10 minutes after clearing the DTCs. (Two trip detection logic is used. After the first road test, turn the power switch off and perform a road test again.)
