On-Board Diagnostics
Fig. 25 Locat ion of Data Link Connecto r (DLC)
On-Board Diagnostics monitors the compo­
nents of you r emission control system. Each
monitored compo nen t in your eng ine system
has been assigned a code . In case of a ma l­
function, the component will be identified
and the fau lt stored as a code in the control
module memory.
The MIL light may a lso illuminate if there is a
leak in the on-board fue l vapor recovery sys­
tem .
If the light illuminates after a refuelling,
stop the vehicle and make sure the fuel filler
cap is properly closed ¢

In o rder to make an accurate diagnosis, the
stored data can only be displayed using spe­
cia l diagnostic equipment (generic scan tool
for OBD).
I n o rder to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (DLC). The DLC is located to the
right of the hood release¢
