Evaporative loss control system
(EVAPS) - leak test - NAS
$% 17.90.02.01
The following procedure allows a fuel leak, indicated
by the Malfunction Indicator Lamp (MIL), to be
accurately located. It must only be carried out once it
has been established that there are no obvious faults
with any of the system components.
Check
1.Check components in fuel and EVAP system
for obvious damage. Ensure all connections
are properly secured.
2.The system must be checked using a EVAPS
Diagnostic Testing Station LRA-19-004.
3.Disconnect vent pipe from purge valve and
connect adapter LRA-19-004/1.
NOTE: The reason for inserting the adapter into
the purge valve is that there is currently no
service port fitted to Freelander.
4.Remove RH rear wheel arch liner.

Liner - rear wheel arch.
5.Release clip and disconnect hose from
charcoal canister.
CAUTION: Before disconnecting any part of
the fuel system, it is imperative that all dust,
dirt and debris is removed from around
components to prevent ingress of foreign
matter into fuel system.
6.Block charcoal canister port with bung,
included in LRA-19-004.
7.Connect LRA-19-004 to service port fitted on
purge valve.
8.Carry out procedures given in the operating
instructions, these are supplied with LRA-19-
004.Adjust
1.If a leak has been detected, replace component
as necessary and repeat leak test to validate
repair.
2.Remove bung from charcoal canister.
3.Connect hose to charcoal canister and secure
with clip.
4.Fit rear wheel arch liner.
