PROCEDURE

1. CHECK FOR DTC

(a) Check for DTCs.

  • for 2WD with NICKEL METAL HYDRIDE BATTERY:

    Click here 2019 - 2020 MY RAV4 HV [11/2018 - 08/2020]; HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM (for 2WD with NICKEL METAL HYDRIDE BATTERY): DTC CHECK / CLEAR

  • for AWD with NICKEL METAL HYDRIDE BATTERY:

    Click here 2019 - 2022 MY RAV4 HV [02/2019 - 10/2022]; HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM (for AWD with NICKEL METAL HYDRIDE BATTERY): DTC CHECK / CLEAR

  • for LITHIUM-ION BATTERY:

    Click here 2020 - 2022 MY RAV4 HV [06/2020 - 10/2022]; HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM (for LITHIUM-ION BATTERY): DTC CHECK / CLEAR

CAUTION:

  • Confirm that DTC P0AA649 (Hybrid / EV Battery Voltage System Isolation Internal Electronic Failure), P1C7C49 (Hybrid / EV Battery Voltage System Isolation (A/C Area) Internal Electronic Failure), P1C7D49 (Hybrid / EV Battery Voltage System Isolation (Hybrid/EV Battery Area) Internal Electronic Failure), P1C7E49 (Hybrid / EV Battery Voltage System Isolation (Transaxle Area) Internal Electronic Failure) or P1C7F49 (Hybrid / EV Battery Voltage System Isolation (Direct Current Area) Internal Electronic Failure), P1C8049 (Hybrid/EV Battery Voltage System Isolation (Rear Motor Area) Internal Electronic Failure, for 4WD/AWD) is not output before removing or installing the HV battery. If this DTC is output, perform troubleshooting for this DTC first.
  • To reduce the risk of electric shock, do not perform troubleshooting before checking for DTCs.

2. PRECAUTION

NOTICE:

After turning the ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

  • To reduce the risk of electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle.
  • To reduce the risk of electric shock, make sure to wait at least 10 minutes after removing the service plug grip to fully discharge the high voltage capacitor inside the inverter with converter assembly.
  • Keep the removed service plug grip in your pocket to prevent other technicians from accidentally installing it while you are servicing the vehicle.

NOTICE:

  • After removing the service plug grip, turning the ignition switch on (READY) may cause a malfunction. Do not turn the ignition switch on (READY) unless instructed by the repair manual.
  • Do not touch the terminals of the service plug grip.
