On-Board Diagnostics
Fig. 9 Locat ion of Data Link Connector (DLC)
On-Board Diagnostics monitors the compo-
nents of your emission control system . Each
controlled component in your engine system
has been assigned a code. In case of a mal-
function, the component will be identified
and the fault stored as a code in the control
module memory.
The MIL lamp may also illuminate if there is a
leak in the on-board fuel vapor recovery sys-
tem. If the light illuminates after a refuelling,
pull off the road and stop the vehicle, then
check that the fuel filler cap is properly closed

In order to make an accurate diagnosis, the
stored data can only be displayed using spe-
cial diagnostic equipment (generic scan tool
for 080) .
In order to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (DLC). The DLC is located to the
right of the engine hood release lever
