• Ignition on
• Wait for 20 seconds.
  NOTE:

  This first verification assumes that download of new software was required in the control module that generated the diagnostic trouble code. If download of new software was not required: read out diagnostic trouble codes and check if the code status is permanent or intermittent to learn how difficult it will be to find the fault.

  Read out the diagnostic trouble codes in the vehicle via the DIAGNOSTICS tab in VIDA (Volvo scan tool).

  Check that the diagnostic trouble code (DTC) for faulty communication is not stored again.

Has the fault been remedied? 

• YES 

  OKAY:  Troubleshooting has been completed.

• NO 

  Refer to TAKING READING ON CABLE IN THE CAN NETWORK (HS-CAN) 

HINT: Once a fault has been repaired, conduct a verification to check that the fault has been remedied.
