WHEN A DTC IS STORED IN TCM

NOTE:
The following timing chart is for DTC of two trip detection diagnosis.
In case of DTC of one trip detection diagnosis, when NG is detected at one trip, MIL turns ON and permanent DTC is displayed.

(*A: For details of these, refer to DTC/CIRCUIT DIAGNOSIS >> DTC (Pxxxx or Uxxx) >> DTC Description >> DTC DETECTION LOGIC.) |
