FS AIR DRAIN CASE REPLACEMENT
SUBJECT:
8.
Connect the GDS and perform the Evap
Leakage Test to ensure a result of No Leak
Detected. This will confirm proper installation
and that the original DTC P0455 condition has
been resolved.
 NOTE
Perform the Evap Leakage test if
possible based on the conditions
mentioned by the GDS screen:
 Make sure DTC were
previously cleared as per
step-1.
 If vehicle fuel level is not
within 20-70%, the test
cannot be conducted.
 To be able to conduct the
test it may be necessary to
let the engine run or drive
the vehicle briefly to get
coolant temperature up to
80C (near to half way on
the cluster gauge).
This is the result when Evap Leakage Test
completes successfully with “No leak
detected.”
 NOTE
If the result shows Leakage
Detected, confirm the repair areas,
then check for leakage from other
areas of the Evap system.
Submit a separate warranty claim
for any additional repair work
required.
Should vehicle conditions not allow for the
Evap Leakage test to be conducted, then this
bulletin’s procedure has ended.
