- Connect the hand-held tester to the Controller Area Network Vehicle Interface Module (CAN VIM). Then connect the CAN VIM to the DLC3.
- Start the engine and warm it up with all the accessories switched OFF until the ECT becomes stable.
- Run the engine at 2,500 to 3,000 RPM for about 3 minutes.
HINT
Control the engine RPM so that the calculated catalyst temperature can be between 550 and 800 °C (1,022 and 1,472°F). The calculated catalyst temperatures of bank 1 and bank 2 can be read by viewing CAT TEMP B1S1 and CAT TEMP B2S1 of the DATA LIST.
Confirm that HO2S bank 1 sensor 1 (OX1A) and bank 2 sensor 1 (OX2A) have waveforms that are around 0.5 V during feedback to the ECM. Then check the waveform of HO2S bank 1 sensor 2 (OX1B) and bank 2 sensor 2 (OX2B) for the same waveforms (0.5 V during feedback).
HINT
If there is a malfunction in the catalyst, the waveform of the rear HO2S (OX1B, OX2B) is almost the same as that of the front HO2S (OX1A, OX2A), which is shown on the left.

- The vehicle must be cold and the ambient tempera must be between 10 to 35°C (50 to 95°F).
- The IAT and the ECT have almost the same values.
- Clear the DTCs (see «DTC CHECK/CLEAR»(ref-209347-S24476769982005120900000) ). Enter the following menus: ADVANCED OBD II / ON-BOARD TEST/ READINESS TESTS. Then the READINESS TEST will show INCMPL (incomplete).
- Drive the vehicle according to the LA#4 driving cycle Note the state of the READINESS TEST. They will change to COMPL (complete) as the EVAP evaluation monitors (EVAP EVAL) operate and if the system passes. This procedure may take 20 minutes or more. NOTE: Do not shut off the engine - the results will be invalid.
