DTC P0ABF-2A: Hybrid/EV Battery Current Sensor "A" Signal Stuck In Range [11/2018 - 08/2020]: Procedure

WARNING: This page is about a different car, the 2020 Toyota RAV4 and 2019 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

CHECK DTC OUTPUT (HYBRID CONTROL)

Connect the Techstream to the DLC3.
Turn the power switch on (IG).
Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

Check and record any HV system DTCs and freeze frame data.

Powertrain > Hybrid Control > Trouble Codes

Result

Result	Proceed to
"Only DTC P0ABF-2A is output" or "DTC P0ABF-2A and DTCs other than those in the following table are output".	A
DTC P0ABF-2A and any of the DTCs in the following table are output at the same time.	B

Turn the power switch off.

Result:

GO TO DTC CHART (HYBRID CONTROL SYSTEM)

Refer to DIAGNOSTIC TROUBLE CODE CHART [11/2018 - 06/2020] , or refer to DIAGNOSTIC TROUBLE CODE CHART [06/2020 - 08/2020]

Result:

See step 2

READ VALUE USING TECHSTREAM

Connect the Techstream to the DLC3.
Turn the power switch on (IG).
NOTE:
Do not turn the power switch on (READY).

Enter the following menus: Powertrain / Hybrid Control / Data List / Hybrid Battery Block 1 to 11 Voltage.

NOTE:

Select "Hybrid Battery Block 1 to 11 Voltage" only. (Do not select any other Data List items.)

Powertrain > Hybrid Control > Data List

Tester Display
Hybrid Battery Block 1 Voltage
Hybrid Battery Block 2 Voltage
Hybrid Battery Block 3 Voltage
Hybrid Battery Block 4 Voltage
Hybrid Battery Block 5 Voltage
Hybrid Battery Block 6 Voltage
Hybrid Battery Block 7 Voltage
Hybrid Battery Block 8 Voltage
Hybrid Battery Block 9 Voltage
Hybrid Battery Block 10 Voltage
Hybrid Battery Block 11 Voltage

Check the voltage of each "Battery Block Vol" of "Hybrid Battery Block 1 to 11 Voltage" in the Data List with the power switch on (IG).

Specified Condition

Any "Battery Block Vol" changes by 0.3 V or more, 60 seconds after the power switch is turned on (IG). (The difference between the maximum and minimum voltage is 0.3 V or more.)

Result

Result	Proceed to
The change in voltage of any "Hybrid Battery Block Voltage" is 0.3 V or more.	A
Other than above	B

Turn the power switch off.

Result:
