Without Scantool

DTC CLEARANCE

- DTCs and freeze frame data can be erased by operating the OBD II scan tool (complying with SAEJ 1978) or LEXUS hand-held tester to erase the codes. (See the OBD II scan tool's instruction for operating instructions.)
- After completing repairs, the DTC retained in memory can be cleared by removing the ECU-B fuse for 10 seconds or more with the ignition switch off.
- Check that the normal code is displayed after connecting the fuse.
