Ecd System (For Dpf) After Treatment Control System

INSPECTION PROCEDURE

TAKE SNAPSHOT DURING IDLING AND 4000 RPM (PROCEDURE 1)

READ VALUE USING INTELLIGENT TESTER (CATALYST DIFFERENTIAL PRESS)

REPLACE FRONT EXHAUST PIPE ASSEMBLY

CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED

INSPECTION PROCEDURE

1. Connect the intelligent tester to the DLC3.
   

2. Start the engine and turn the tester on.

4. Take a snapshot of the following Data List items.
   

   Text in Illustration

   *1	Snapshot Button
   *a	Reference

   HINT:

   1. A snapshot can be used to compare vehicle data from the time of the malfunction to normal data and is very useful for troubleshooting. The data in the list below is that of a normal vehicle, but as the data varies between individual vehicles, this data should only be used for reference.
      
   2. Graphs like the ones shown below can be displayed by transferring the stored snapshot data from the tester to a PC (Personal Computer). Intelligent Viewer must be installed on the PC.
      
   3. Check the Data List at idling and at 4000 rpm with no load after the engine is warmed up.
      

1. Check Catalyst Differential Press in the snapshot taken in procedure 1 when the engine was running at 4000 rpm with no load.
