DTC Confirmation ProcedureNBS00516
NOTE:
If DTC P0456 is displayed with P0442, first perform trouble diagnosis for DTC P0456.
After repair, make sure that the hoses and clips are installed properly.
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait
at least 10 seconds before conducting the next test.
TESTING CONDITION:
Open engine hood before conducting following procedure.
If any of following conditions are met just before the DTC confirmation procedure, leave the vehi-
cle for more than 1 hour.
–Fuel filler cap is removed.
–Fuel is refilled or drained.
–EVAP component parts is/are removed.
Before performing the following procedure, confirm that battery voltage is more than 11V at idle.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode with
CONSULT-II.
2. Make sure the following conditions are met.
FUEL LEVEL SE: 0.25 - 1.4V
COOLAN TEMP/S: 0 - 32
C (32 - 90F)
FUEL T/TMP SE: 0 - 35
C (32 - 95F)
INT A/TEMP SE: More than 0
C (32F)
If NG, turn ignition switch OFF and leave the vehicle in a cool
place (soak the vehicle) or refilling/draining fuel until the output
voltage condition of the “FUEL LEVEL SE” meets within the
range above and leave the vehicle for more than 1 hour. Then
start from step 1).
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Turn ignition switch ON.
5. Select “EVAP V/S LEAK P0456/P1456” of “EVAPORATIVE SYSTEM” in “DTC WORK SUPPORT” mode
with CONSULT-II.
Follow the instruction displayed.
6. Make sure that “OK” is displayed.
If “NG” is displayed, refer to EC-469, "
Diagnostic Procedure" .
NOTE:
