INFOID:0000000009719819
OUTLINE
When a DTC is stored in ECM
When a DTC is stored in ECM and MIL is ON, a permanent DTC is erased with MIL shutoff if the same mal-
function is not detected after performing the driving pattern for MIL shutoff three times in a raw.
When a DTC is not stored in ECM
The erasing method depends on a permanent DTC stored in ECM. Refer to the following table.
NOTE:
If the applicable permanent DTC includes multiple groups, perform the procedure of Group B first. If the per-
manent DTC is not erased, perform the procedure of Group A.
