CHECK FOR CURRENT DTC
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.
