P2423 HC ADSORPTION CATALYST FUNCTION

DTC Logic

INFOID:0000000004211622

DTC DETECTION LOGIC

The ECM monitors the phase gap between heated oxygen sensor 2

signal and heated oxygen sensor 3 signal.

The phase gap between heated oxygen sensor 2 signal and heated

oxygen sensor 3 signal becomes small as the HC adsorption cata-

lyst (under floor) is deteriorated.

When the phase gap between heated oxygen sensor 2 signal and

heated oxygen sensor 3 signal approaches a specified limit value,

the HC adsorption catalyst (under floor) malfunction is diagnosed.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following before conduct-

ing the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

CAUTION:

Always drive vehicle in safe manner according to traffic conditions and obey all traffic laws.

With CONSULT-III

1. Activate “INSPECTION MODE 1” (

HBC-104

) to start engine, and warm up engine to normal operating

temperature.

2. Turn ignition switch OFF and wait at least 10 seconds.

3. Turn ignition switch ON.

4. Turn ignition switch OFF and wait at least 10 seconds.

5. Turn ignition switch ON (READY).

6. Repeat following procedure 2 times.

-

Drive vehicle at a speed of 80 km/h (50 MPH) or more for at least 3 consecutive minutes.

NOTE:

Keep the vehicle speed as steady as possible during the cruising.

-

Stop vehicle.

NOTE:

Never turn ignition switch OFF.

7. Select “DTC & SRT CONFIRMATION” then “SRT WORK SUPPORT” mode with CONSULT-III.

8. Drive vehicle at a speed of 80 km/h (50 MPH) or more until “INCMP” of “CATALYST” changes to “CMPLT”.

NOTE:

• Keep the vehicle speed as steady as possible during the cruising.

• It will take at most 3 minutes until “INCMP” of “CATALYST” changes to “CMPLT”.

9. Check 1st trip DTC.
