2.3 Location of the Data Link Connector (DLC)

 

The DLC  (Data  Link  Connector  or  Diagnostic  Link  Connector)  is  the 
standardized  16-cavity  connector where  diagnostic  scan  tools interface 
with  the  vehicle's  on-board  computer.  The  DLC  is  usually located  12 
inches  from  the  centre  of  the  instrument  panel  (dash), under  or 
around  the  driver’s  side  for  most  vehicles. For  some vehicles, the DLC 
is  located  in the passenger foot-well and in others it may be behind  the 
ashtray. Refer to the vehicle’s service manual for the location if the DLC 
cannot be found. 

2.4 OBD II Readiness Monitors

 

An  important part  of  a  vehicle’s  OBDII  system  are  the  Readiness 
Monitors,  which  are  indicators  used  to  find  out  if  all

 

of  the  emissions 

components  have  been  evaluated  by  the  OBD  II  system.  Periodic 
tests  are run on  specific  systems  and  components  to  ensure that they 
are performing within allowable limits.
