2. 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(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 a DTC.

With 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.
