HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION

How to Erase DTC

With CONSULT-III

The emission related diagnostic information in the ECM can be erased by selecting “ALL Erase” in the

“Description” of “FINAL CHECK” mode with CONSULT-III.

With GST

The emission related diagnostic information in the ECM can be erased by selecting Service $04 with GST.

1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 10

seconds and then turn it ON (engine stopped) again.

2. Perform

TM-34, "OBD-II Diagnostic Trouble Code (DTC)"

. (The DTC in TCM will be erased.)

1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once.

Wait at least 10 seconds and then turn it ON (engine stopped) again.

2. Perform

TM-34, "OBD-II Diagnostic Trouble Code (DTC)"

. (The DTC in TCM will be erased.)

3. Change the diagnostic test mode from Mode II to Mode I by depressing the accelerator pedal. Refer to

EC-71, "Malfunction Indicator Lamp (MIL)"

•

If the battery is disconnected, the emission-related diagnostic information will be lost within 24

hours.

•

The following data are cleared when the ECM memory is erased.

- Diagnostic trouble codes

- 1st trip diagnostic trouble codes

- Freeze frame data

- 1st trip freeze frame data

- System readiness test (SRT) codes

- Test values

Actual work procedures are explained using a DTC as an example. Be careful so that not only the DTC, but all

of the data listed above, are cleared from the ECM memory during work procedures.

How to Erase Permanent DTC

When a DTC is stored in ECM

• When a DTC is stored in ECM and MIL is ON, a permanent DTC is erased with MIL shutoff if the same mal-

function is not detected after performing the driving pattern for MIL shutoff three times in a raw.

When a DTC is not stored in ECM

• The erasing method depends on a permanent DTC stored in ECM. Refer to the following table.

: Applicable —: Not applicable

*: For group, refer to

EC-464, "Emission-related Diagnostic Information"

, “EMISSION-RELATED DIAGNOSTIC INFORMATION

ITEMS”.

Group A

*1: When the same malfunction is de-

tected in two consecutive trips, MIL
will illuminate.

*2: MIL will turn off after vehicle is driven

3 times (pattern B) without any mal-
functions.

5. Check permanent DTC. Refer to

EC-464, "Emission-related Diagnostic Information"

, “How to Display Per-

manent DTC Status”.

6. Perform “DTC CONFIRMATION PROCEDURE” for DTCs which are the same as permanent DTCs stored

in ECM.

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

8. Turn ignition switch ON.

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

NOTE:

• Drive the vehicle according to only driving patterns indicating “INCMP” in driving patterns B and D on the

“PERMANENT DTC STATUS” screen.

• When experiencing both driving pattern B and D during the same trip, the experience of driving pattern D is

counted by priority.

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.

4. Turn ignition switch ON.

5. Check permanent DTC. Refer to

EC-464, "Emission-related Diagnostic Information"

, “How to Display Per-

manent DTC Status”.

6. Start engine and warm it up to normal operating temperature.

7. Drive the vehicle according to driving pattern D.

CAUTION:

• Always drive at a safe speed.

• Never erase self-diagnosis results.

• If self-diagnosis results are erased during the trip of driving pattern B or D, the counter of driving

pattern B or D is reset.

• If self-diagnosis results are erased during the trip of driving pattern B or D, an experience of driv-

ing pattern B and D during the same trip is not counted up.

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

9. Turn ignition switch ON.

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

11. Turn ignition switch ON.

12. Use “PERMANENT DTC WORK SUPPORT” to drive the vehicle according to driving pattern B.

*1: When the same malfunction is de-

tected in two consecutive trips, MIL
will illuminate.

*2: After experiencing Driving pattern B

and D, permanent DTC is erased.

*3: Indication does not change unless

the ignition switch is turned from ON
to OFF twice even after experiencing
Driving pattern B or D.
