WARNING: This page is about a different car, the 2009 Toyota Tacoma. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Be sure to read Description before performing the following procedures.
  1. CHECK FOR DTC OF OTHER COMPONENTS 
    1. Check if the component shown by the sub-code is displayed in the check result of the other components.
      1. Check if "01-DC" is output for the other components.
      2. If "01-DC" is output for any other components, check if the same physical address is displayed.

        Result 

        RESULT CHART

        Result Proceed to
        "01-DC" is output and the same physical address is displayed A
        "01-DC" is not output or the same physical address is not displayed B

        HINT:

        For the list of the components shown by sub-codes, refer to the table in step 2.

        B:  Go to step  4

        A: Go to next step. 

  2. IDENTIFY THE COMPONENT WHICH HAS STORED THIS CODE

    COMPONENT REFERENCE

    Component Physical Address
    Stereo component amplifier 440
    Radio receiver 190
    "Bluetooth" handsfree module 19D

    HINT:

    • "440 (stereo component amplifier)" is the component which has stored this code in the example shown in the illustration.
    • For details of the DTC display, refer to DTC Check/Clear (See DTC CHECK/CLEAR ).
  3. CHECK COMPONENT WHICH HAS STORED THIS CODE 
    1. Select the component which has stored this code.

      Component Table 

      COMPONENT REFERENCE

      Component Proceed to
      Stereo component amplifier Stereo component amplifier communication error (See STEREO COMPONENT AMPLIFIER COMMUNICATION ERROR )
      Radio receiver Radio receiver communication error (See RADIO RECEIVER COMMUNICATION ERROR )
      "Bluetooth" handsfree module "Bluetooth" handsfree module communication error (See BLUETOOTH HANDSFREE MODULE COMMUNICATION ERROR )

      NEXT: END 

  4. CLEAR DTC 
    1. Clear the DTCs (See DTC CHECK/CLEAR ).

      HINT:

      If "01-DC" is output for only one component, this may not indicate a malfunction.

  5. RECHECK FOR DTC 
    1. Recheck for DTCs and check if the same trouble occurs again.

      OK: Malfunction disappears. 

    NG: Go to step 6 

    OK: END 

  6. CHECK COMPONENT WHICH HAS STORED THIS CODE 
    1. Select the component which has stored this code.
