CHECK FOR CURRENT DTC
Note: Since a hot vehicle can conceal a leak, it is best to perform
this test at room temperature.
Note: A loose fuel filler cap could have caused this DTC to set.
Make sure fuel filler cap is tight and in good condition. Ensure
the fuel filler cap meets OEM specifications.
Note: If the PCM detects and stores a DTC, the PCM also stores
the engine/vehicle operating conditions under which the DTC was
set. Some of these conditions are displayed on the DRB III at the
same time the DTC is displayed.
Note: Before erasing stored DTCs, record these conditions.
Attempting to duplicate these conditions may assist when check-
ing for an active DTC.
Turn the ignition on.
With the DRB III , erase PCM DTCs.
Note: It maybe necessary to road test the vehicle for this DTC to set.
With the DRB III , read PCM DTCs.
