  • Motor generator control ECU (MG ECU) malfunction
  • Communication (wire harness) malfunction

High voltage system malfunction

  • HV battery malfunction
  • HV battery junction block assembly malfunction

  • Hybrid/EV Battery Voltage
  • VL-Voltage before Boosting
  • VH-Voltage after Boosting
  • Boost Ratio

MONITOR DESCRIPTION

The hybrid vehicle control ECU assembly monitors signals of HV battery voltage (VB) and boost converter voltage (VL) sensors. When a large difference occurs between the voltages from the VB and VL sensors, the hybrid vehicle control ECU assembly interprets this as a failure of either of the sensors. The hybrid vehicle control ECU assembly will illuminate the MIL and store a DTC.

CONFIRMATION DRIVING PATTERN

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 2020 - 2024 MY RAV4 HV [06/2020 -        ]; HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM (for LITHIUM-ION BATTERY): UTILITY

  • When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.

  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch to ON and turn the Techstream on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  4. Turn the ignition switch off and wait for 2 minutes or more.
  5. Turn the ignition switch to ON and turn the Techstream on.
  6. Turn the ignition switch to ON (READY). [*1]
  7. With the shift lever in D, depress both the accelerator pedal and brake pedal at the same time to raise the "Hybrid/EV Battery SOC" to a sufficient level. [*2]
  8. Move the shift lever to P, check that the engine is stopped and move the shift lever to N. [*3]
  9. Set the A/C for maximum cooling. [*4]
  10. Leave the vehicle for a few minutes. [*5]

    HINT:

    • When the accelerator pedal is not depressed with the ignition switch ON (READY) and shift lever in P, if "VL-Voltage before Boosting" and the "Hybrid/EV Battery Voltage" is approximately the same after repair, the condition is judged as normal.
    • [*1] to [*5] : Normal judgment procedure.

      The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

  11. Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.
  12. 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, perform the normal judgment procedure again.
