All 1994–97 2TZ-FZE engines are equipped with OBD II.
NOTE: These models require the use of the Toyota's hand held
scan tool or an equivalent OBD II compliant scan tool.
- Prepare the scan tool according to the manufacturers instructions.
- Connect the OBD II scan tool, to the DLC3 in the fuse box located in the
center upper portion of the instrument panel.

freeze frame data recorded. Before switching modes, always check the DTC
and freeze frame data and write them down.

scan tool switch on.
- Use the OBD II scan tool to check the DTC and freeze frame data. Write them
