    Possible Sources 

    • Suspect Module

  2. N1 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE MODULE SENDING INVALID DATA

    • Using a diagnostic scan tool, carry out the self-test for the module in question sending the invalid data.

    Are any Diagnostic Trouble Codes (DTCs) present from the module sending the invalid data? 

    Yes  DIAGNOSE the module sending the invalid data. Refer to the appropriate service information.
    No  DIAGNOSE the observable symptom.
