Tech Tips

After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.


  1. Turn the ignition switch to ON (IG) and wait for a few seconds.

PROCEDURE


  1. CHECK CONNECTOR CONNECTION CONDITION (POWER MANAGEMENT CONTROL ECU CONNECTOR)


    1. A01V0I0E01
      Text in Illustration
      *A for LHD
      *B for RHD

      Check the connector connections and contact pressure of the relevant terminals for the power management control ECU connectors Click here.

      OK
      The connectors are connected securely and there are no contact pressure problems.

    NG

    CONNECT SECURELY

    OK

  2. CHECK AUXILIARY BATTERY TERMINAL (CONTACT PROBLEM)


    1. Check the connection of the auxiliary battery terminal.

      OK
      The terminal is connected securely and there is no contact problem.

    NG

    CONNECT SECURELY

    OK

  3. INSPECT AUXILIARY BATTERY

    Click here


    NG

    CHARGE OR REPLACE AUXILIARY BATTERY

    OK

  4. CHECK FUSE (ECU-B NO. 2)


    1. Remove the ECU-B NO. 2 fuse from the No. 2 engine room relay block.

      *1 No. 2 Engine Room Relay Block
      *2 ECU-B NO. 2 Fuse

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      ECU-B NO. 2 fuse Ignition switch off Below 1 Ω

    3. Install the ECU-B NO. 2 fuse.


    NG

    REPLACE FUSE (ECU-B NO. 2)

    OK

  5. CHECK HARNESS AND CONNECTOR (POWER MANAGEMENT CONTROL ECU - ECU-B NO. 2 FUSE)


    1. Remove the ECU-B NO. 2 fuse from the No. 2 engine room relay block.

    2. Disconnect the power management control ECU connector.

    3. Measure the resistance according to the value(s) in the table below.

      Note

      When taking measurements with a tester, do not apply excessive force to the tester probes to avoid damaging the fuse holder or terminals.

      Standard Resistance (Check for Short)
      Tester Connection Switch Condition Specified Condition
      F55-1 (BATT) or 2 (ECU-B NO. 2 fuse) - Body ground and other terminals Ignition switch off 10 kΩ or more

    4. Install the ECU-B NO. 2 fuse.

    5. Connect the power management control ECU connector.


    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  6. CHECK HARNESS AND CONNECTOR (ECU-B NO. 2 FUSE - AUXILIARY BATTERY POSITIVE TERMINAL)


    1. Disconnect the positive and negative terminals from the auxiliary battery.

    2. Remove the ECU-B NO. 2 fuse from the No. 2 engine room relay block.

      *1 No. 2 Engine Room Relay Block
      *2 ECU-B NO. 2 Fuse

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance (Check for Open)
      Tester Connection Switch Condition Specified Condition
      1 (ECU-B NO. 2 fuse) - Positive (+) battery terminal Ignition switch off Below 1 Ω
      Standard Resistance (Check for Short)
      Tester Connection Switch Condition Specified Condition
      1 (ECU-B NO. 2 fuse) or Positive (+) battery terminal - Body ground and other terminals Ignition switch off 10 kΩ or more

    4. Install the ECU-B NO. 2 fuse.

    5. Connect the positive and negative terminals to the auxiliary battery.


    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  7. RECONFIRM DTC OUTPUT (HYBRID CONTROL)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

    4. Recheck for DTCs.

      Result
      Result Proceed to
      DTC P0560-117 is output again A
      DTC P0560-117 is not output B

      Tech Tips

      If DTC P0560-117 is output after this inspection, replace the power management control ECU. If the DTC is not output, check for intermittent problems Click here because there may be a malfunction in the wire harness or connector.
