2. Perform one of the following tasks based on your verification results:
   * If the previous steps did not clear the fault, refer to doc 1004229.1 for information about the tools and methods you can use to diagnose and clear component faults.
   * If the previous steps indicate that no faults have been detected, then the component has been replaced successfully. No further action is required
