DESCRIPTION
- Refer to the circuit description for DTC P0A80-123 P0A80.





HINT: DTCs from P3011-123 to P3029-123 cannot be set unless the vehicle is driven for approximately 10 minutes after clearing the DTCs.

MONITOR DESCRIPTION

If there is an abnormal internal resistance or electromotive voltage in the battery blocks, the battery smart unit determines that a malfunction has occurred. When the malfunction detection condition is satisfied, the hybrid vehicle control ECU will illuminate the MIL and set a DTC.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC OUTPUT (DTC P0A1F-123 IS OUTPUT)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Select the following menu items: Powertrain / Hybrid Control / Trouble Codes.
(d) Check if DTCs are output.
Result:
DTC P0A1F-123 is output.
YES -- GO TO INSPECTION PROCEDURE RELEVANT TO OUTPUT DTC
NO -- Continue to next step.
2. CHECK BATTERY SMART UNIT
(a) Ensure the safety of the areas in front and rear of the vehicle.
(b) Connect the Techstream to the DLC3.
(c) Turn the power switch on (READY).
(d) Select the following menu items: Powertrain / Hybrid Control / Data List / Battery Block Vol -V01 to V20.
(e) Fully warm up the engine and turn the air conditioning off.
(f) Firmly depress the brake pedal with your left foot.
(g) Move the shift lever to the D position.
(h) Record each battery block voltage from the data list (Battery Block Vol -V01 to V20) while fully depressing the accelerator pedal.
(i) 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.





(j) Check if the difference in voltage of each combination is 0.3 V or more.
Result:





HINT: Difference in voltage of each combination may be 0.3 V or more due to a battery smart unit internal error.

B -- REPLACE BATTERY SMART UNIT
A -- REPLACE HV BATTERY
