The length of time the 1,000th-digit numeral flashes on
and off is 1.2 seconds consisting of an ON (0.6-sec-
onds) - OFF (0.6-seconds) cycle.
The 100th-digit numeral and lower digit numerals consis t of a 0.3-seconds ON and 0.3-seconds OFF cycle.
A change from one digit numeral to another occurs at an inte rval of 1.0-second OFF. In other words, the later
numeral appears on the display 1.3 seconds after the former numeral has disappeared.
A change from one trouble code to another occurs at an interval of 1.8-seconds OFF.
In this way, all the detected malfunctions are classi fied by their DTC numbers. The DTC 0000 refers to no mal-
function. Refer to EC-630, "DTC Index"
.
How to Erase Self-diagnostic Results
By performing this procedure, ECM memory is erased and the following diagnostic information is erased as
well.
• Diagnostic trouble codes
• 1st trip diagnostic trouble codes
• Freeze frame data
• 1st trip freeze frame data
• System readiness test (SRT) codes
• Test values
NOTE:
Also, if a battery terminal is disconnected, ECM memory is erased and the diagnostic information as listed
above is erased. (The amount of time required for eras ing may vary from a few seconds to several hours.)
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. Set ECM in “self-diagnostic results” mode.
6. The diagnostic information has been erased from the backup memory in the ECM. Fully depress the accelerator pedal and keep it depressed for more than 10 seconds.
7. Fully release the accelerator pedal, and confirm the DTC 0000 is displayed.

How to Read DTC and 1st Trip DTC
Diagnostic test mode Function
Self Diagnostic Result Self-diagnostic results such as 1st trip DTC, DTCs and 1st trip freeze frame data or freeze frame data
can be read and erased quickly.
*
Data Monitor Input/Output data in the ECM can be read.
Work support This mode enables a technician to adjust some devices faster and more accurately by following the in-
dications on the CONSULT unit.
Active Test Diagnostic Test Mode in which CONSULT drives some actuators apart from the ECMs and also shifts
some parameters in a specified range.
ECU Identification ECM part number can be read.
DTC Work Support The status of system monitoring tests and the self-diagnosis status/results can be confirmed.

DIAGNOSIS SYSTEM (ECM)
DTCs and 1st trip DTCs related to the malf
unction are displayed in “self-diag results”.
• When ECM detects a 1st trip DTC, 1t” is displayed for “TIME”.
• When ECM has detected a current DTC, “0” is displayed for “TIME”.
• If “TIME” is neither “0” nor “1t”, the DTC occurred in the past and ECM shows the number of times the vehi-
cle has been driven since the last detection of the DTC.
How to Erase DTC and 1st Trip DTC
NOTE:
• If the ignition switch stays ON after repair work, be su re to turn ignition switch OFF once. Wait at least 10
seconds and then turn it ON (engine stopped) again.
• If the DTC is not for A/T related items (see EC-630, "DTC Index"
), skip step 1.
1. Select “ENGINE” with CONSULT.
2. Select “SELF-DIAG RESULTS”.
3. Touch “ERASE”. (DTC in ECM will be erased.)
Freeze Frame Data and 1st Trip Freeze Frame Data
*: The items are the same as those of 1st trip freeze frame data.
DATA MONITOR MODE
NOTE:
• The following table includes information (items) inapplicable to this vehicle. For information (items) applica- ble to this vehicle, refer to CONSULT display items.
• For reference values of the following items, refer to EC-613, "Reference Value"
