1. Precautions

If the DPD is replaced, perform the following.

2. Differential pressure sensor learning

1) Connect the scan tool to the DLC.

2) Turn ON the ignition switch.

3) Observe that the following items are less than or equal to the standard value on the scan tool.

Standard: 60 ℃ { 140 °F }

4) Select the scan tool item.

5) Perform the exhaust differential pressure sensor learning by following the on-screen instructions.

6) The procedure is complete when the Exhaust Pressure Learning End Status parameter changes from Not Completed to Completed.

7) Turn OFF the ignition switch after the exhaust differential pressure sensor learning is complete.

3. DPD regeneration data reset

1) Turn ON the ignition switch.

2) Select the scan tool item.

3) Perform the DPD regeneration data reset by following the on-screen instructions.

4) After completing the DPD regeneration data reset, turn OFF the ignition switch.
