1. 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(R) at the same time the DTC is displayed.
NOTE: Before erasing stored DTCs, record these conditions. Attempting to duplicate these conditions may assist when checking for an active DTC.

Turn the ignition on.

With the DRB III(R), erase PCM DTCs.

NOTE: It maybe necessary to road test the vehicle for this DTC to set.

With the DRB III(R), read the PCM DTCs.
