DIAGNOSIS SYSTEM (ECM)
NOTE:
Wait until the same DTC (or 1st trip DTC) appears to completely confirm all DTCs.
How to Read Self-diagnostic Results
The DTC and 1st trip DTC are indicated by the number of blinks of the MIL as shown below.
The DTC and 1st trip DTC are displayed at the same time. If the MIL does not illuminate in diagnostic test
mode I (Malfunction warning), all displayed items are 1st trip DTCs. If only one code is displayed when the MIL
illuminates in “malfunction warning” mode, it is a DTC; if two or more codes are displayed, they may be either
DTCs or 1st trip DTCs. DTC No. is same as that of 1st trip DTC. These unidentified codes can be identified by
using the CONSULT or GST. A DTC will be used as an example for how to read a code.
A particular trouble code can be identified by the number of four-digit numeral flashes per the following.
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 consist of a 0.3-seconds ON and 0.3-seconds OFF cycle.
A change from one digit numeral to another occurs at an interval 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 classified by their DTC numbers. The DTC 0000 refers to no mal-
function. Refer to
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 erasing 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.
CONSULT Function
INFOID:0000000009753117
FUNCTION
*: The following emission-related diagnostic information is 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
SELF DIAGNOSTIC RESULTS MODE
Self Diagnostic Item
Regarding items of DTC and 1st trip DTC, refer to
How to Read DTC and 1st Trip DTC
DTCs and 1st trip DTCs related to the malfunction 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.
Diagnostic test mode
Function
Self Diagnostic Results
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.

SRT & P-DTC MODE
SRT STATUS Mode
• For items whose SRT codes are set, “CMPLT” is displayed on the CONSULT screen; for items whose SRT
codes are not set, “INCMP” is displayed.
• “SRT STATUS” provides the presence or absence of permanent DTCs stored in ECM memory.
PERMANENT DTC STATUS Mode
How to display permanent DTC status
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.
Select “PERMANENT DTC STATUS” in “DTC & SRT CONFIRMATION” mode with CONSULT.
NOTE:
Permanent DTCs stored in ECM memory are displayed on the CONSULT screen to show if a driving pat-
tern required for erasing permanent DTCs is complete (CMPLT) or incomplete (INCMP).
CAUTION:
Since the “PERMANENT DTC STATUS” screen displays the previous trip information, repeat the
following twice to update the information: “Ignition switch OFF”, “Wait for more than 10 seconds”
and “Ignition switch ON”.
NOTE:
This mode is not used in regions that permanent DTCs are not regulated by law.
SRT WORK SUPPORT Mode
This mode enables a technician to drive a vehicle to set the SRT while monitoring the SRT status.
PERMANENT DTC WORK SUPPORT Mode
This mode enables a technician to drive a vehicle to complete the driving pattern that is required for erasing
permanent DTC.
NOTE:
This mode is not used in regions that permanent DTCs are not regulated by law.

VALUES ON THE DIAGNOSIS TOOL
NOTE:
The following table includes information (items) inapplicable to this vehicle. For information (items) applicable
to this vehicle, refer to CONSULT display items.
z
Numerical values in the following table are reference values.
z
These values are input/output values that ECM receives/transmits and may differ from actual operations.
Example:
The ignition timing shown by the timing light may differ from the ignition timing displayed on the data monitor.
This occurs because the timing light shows a value calculated by ECM according to signals received from the
cam shaft position sensor and other sensors related to ignition timing.
For outlines of following items, refer to
