Only one set of freeze frame data (either 1st trip freeze frame data or freeze frame data) can be stored in the
ECM. 1st trip freeze frame data is stored in the ECM memory along with the 1st trip DTC. There is no priority
for 1st trip freeze frame data, and it is updated each time a different 1st trip DTC is detected. However, once
freeze frame data (2nd trip detection/MI on) is stored in the ECM memory, 1st trip freeze frame data is no
longer stored. Remember, only one set of freeze frame data can be stored in the ECM. The ECM has the fol-
lowing priorities to update the data.

Both 1st trip freeze frame data and freeze frame data (along with the DTC) are cleared when the ECM mem-
ory is erased.

How to Erase DTC

• The diagnostic trouble code can be erased by CONSULT-III, GST or ECM DIAGNOSTIC TEST MODE as

described following.

- If the battery cable is disconnected, the diagnostic trouble code will be lost within 24 hours.
- When you erase the DTC, using CONSULT-III or GST is easier and quicker than switching the mode

selector on the ECM.

• The following emission-related diagnostic information is cleared from the ECM memory when erasing DTC

related to OBD. For details, refer to

EC-962, "DTC Index"

.

- Diagnostic trouble codes (DTC)
- 1st trip diagnostic trouble codes (1st trip DTC)
- Freeze frame data
- 1st trip freeze frame data
- System readiness test (SRT) codes
- Test values

How to Erase DTC (With CONSULT-III)

The emission related diagnostic information in the TCM and ECM can be erased by selecting “ALL Erase” in
the “Description” of “FINAL CHECK” mode with CONSULT-III.

How to Erase DTC (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.

Select Mode 4 with GST (Generic Scan Tool). For details, refer to

EC-719, "CONSULT-III Function"

(WITH

EURO-OBD),

EC-1054, "CONSULT-III Function"

(WITHOUT EURO-OBD).

MALFUNCTION INDICATOR (MI)

Description

The MI is located on the instrument panel.

1.

The MI will light up when the ignition switch is turned ON without
the engine running. This is a bulb check.
• If the MI does not light up, refer to

EC-934, "Component Func-

tion Check"

(WITH EURO-OBD),

EC-1213, "Component Func-

tion Check"

(WITHOUT EURO-OBD).

2.

When the engine is started, the MI should go off.
If the MI remains on, the on board diagnostic system has
detected an engine system malfunction.

CONSULT-III can display each diagnostic item using the diagnostic test modes shown below.

FUNCTION

WORK SUPPORT MODE

Display Item List

Engine Brake Adjustment

CAUTION:

Mode of “+1”“0”“

1”“

2”“OFF” can be selected by pressing the “UP”“DOWN” on CONSULT-III screen.

However, do not select mode other than “0” and “OFF”. If the “+1” or “

1” or “–2” is selected, that

might cause the irregular driveability.

Check CVT Fluid Deterioration Date

CAUTION:

Touch “CLEAR” after changing CVT fluid, and then erase “CVTF DETERIORATION DATE”.

SELF-DIAGNOSTIC RESULT MODE

After performing self-diagnosis, place check marks for results on the

TM-187, "Diagnostic Work Sheet"

. Refer-

ence pages are provided following the items.

Display Items List

Diagnostic test mode

Function

Work support

This mode enables a technician to adjust some devices faster and more accurately by following the in-
dications on CONSULT-III.

Self-diagnostic results

Self-diagnostic results can be read and erased quickly.

Data monitor

Input/Output data in the TCM can be read.

CAN diagnostic support mon-
itor

The results of transmit/receive diagnosis of CAN communication can be read.

CALIB data

Characteristic information for TCM and CVT assembly can be read. Do not use, but displayed.

Function test

Performed by CONSULT-III instead of a technician to determine whether each system is “OK” or “NG”.

ECU part number

TCM part number can be read.
