DTC CHECK / CLEAR
1. CHECK DTC
DTCs which are stored in the ECM can be displayed with the
hand−held tester.
These scan tools can display pending DTCs and current DTCs.
Some DTCs are not stored if the ECM does not detect a mal-
function during consecutive driving. However, the detected
malfunction during once driving is stored as pending DTC.

check the DTCs, use the normal mode. For DTC chart sub-
ject to "2 trip detection logic", perform either of the follow-

once. Then repeat the simulation process again. When the
problem has been simulated twice, the MIL illuminates and the
DTCs are recorded in the ECM.
