  4. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
    • Check that the program card is correctly installed.
    • Check the connections to the vehicle.
    • Check the ignition switch position.
  5. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
  6. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
    • CAN circuit fault; all electronic control units no response/not equipped, refer to MODULE COMMUNICATIONS NETWORK .
    • No response/not equipped for the audio unit, GO to PINPOINT TEST A .
      • NOTE: Do not press any buttons on the audio unit while the audio unit is carrying out the self-test.
    • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out self-test diagnostics for the audio unit.
  7. If the DTCs retrieved are related to the concern, go to AUDIO UNIT DIAGNOSTIC TROUBLE CODE (DTC) INDEX .
  8. If no DTCs related to the concern are retrieved, and the concern is not visually evident, proceed to the SPEAKER WALK-AROUND TEST , AUDIO UNIT SELF-DIAGNOSTIC MODE , or NAVIGATION SELF-DIAGNOSTICS .
