Title: HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM (for AWD with NICKEL METAL HYDRIDE BATTERY): P060A94; Hybrid/EV Powertrain Control Module Monitoring Processor Unexpected Operation; 2019 - 2024 MY RAV4 HV [02/2019 -        ]

DTC

P060A94

Hybrid/EV Powertrain Control Module Monitoring Processor Unexpected Operation

DTC SUMMARY

MALFUNCTION DESCRIPTION

The main CPU and sub CPU of the hybrid vehicle control ECU assembly monitor their internal operation and each other for malfunctions.

The cause of this malfunction may be the following:

Hybrid vehicle control ECU assembly internal malfunction

  • Hybrid vehicle control ECU assembly malfunction

Vehicle speed sensor malfunction

  • Discrepancy between motor resolver signal and actual vehicle speed

DESCRIPTION

The hybrid vehicle control ECU assembly monitors its internal operation and will store these DTCs when it detects an internal malfunction.

DTC No.

  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) and wait for 10 seconds or more. [*1]

    HINT:

    [*1]: Normal judgment procedure.

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

  7. Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.
  8. 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.
