(4) Use the OBD II scan tool or TOYOTA hand−held
tester to check the DTCs and freeze frame data.
Note them down (For operating instructions, see
the OBD II scan tool’s instruction book).
(5) See page DI−143 to confirm the details of the
DTCs.

When simulating symptoms with an OBD II scan tool (ex-
cluding TOYOTA hand −held tester) to check the DTCs, use
the normal mode. For codes on the DTC chart subject to ”2
trip detection logic”, turn the ignition switch off after the
symptoms have been simulated for the 1st time. Them re-
peat the simulation process again. When the program has
been simulated twice, the MIL lights up and the DTCs are
recorded in the ECM.
