This  special  Control  Mode  requests  control  of  the 

on-board  system,  test,  or  component  bi-directionally  (where 
applicable). 

This mode is manufacturer specific.

Requests  Emission-Related  Diagnostic  Trouble 

Codes  with  Permanent  Status.

  This  mode  is  required  for  all 

emissions-related  DTCs.  The  presence  of  permanent  DTCs  at  an 
inspection without the MIL illuminated is an indication that a proper
