terminal connections can set DTCs.
Note: Check for applicable TSBs related to the problem.

CHECK FOR CURRENT DTC

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.
