CONFIRMATION DRIVING PATTERN

A01I2VEE01

  1. Connect the Techstream to the DLC3.

  2. Turn the power switch on (IG) and turn the Techstream on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the power switch off and wait for 30 seconds or more.

  5. Turn the power switch on (IG) and turn the Techstream on.

  6. Turn the power switch on (READY) and wait for 2 minutes or more. [A]

  7. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes. [B]

  8. Read the current DTCs.

    Tech Tips


    • If a current DTC is output, the system is malfunctioning.

    • If current DTCs are not output, perform the following steps to check for permanent DTCs.

  9. Check that the permanent DTCs are cleared.

  10. If the permanent DTCs are not cleared, perform a universal trip, and then check for permanent DTCs again.

INSPECTION PROCEDURE

Tech Tips

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


  1. Turn the power switch on (IG) and wait for 2 minutes or more.

PROCEDURE


  1. CHECK DTC OUTPUT (ALL)


    1. Connect the Techstream to the DLC3.

    2. Turn the power switch on (IG).

    3. Check for DTCs of all systems by following the prompts on the Techstream screen.

    4. Check if DTCs are output.

      Result
      Result Proceed to
      Power management control ECU outputs P2532-772 A
      Power management control ECU does not output P2532-772 B

    5. Turn the power switch off.
