Both 1st trip freeze frame data and freeze frame dat
a (along with the DTCs) are cleared when the ECM mem-
ory is erased. Procedures for clearing the ECM me mory are described in "EMISSION-RELATED DIAGNOS-
TIC INFORMATION ITEMS".
SYSTEM READINESS TEST (SRT) CODE
System Readiness Test (SRT) code is specified in Service $01 of SAE J1979/ISO 15031-5.
As part of an enhanced emissions test for Inspection & Ma intenance (I/M), certain states require the status of
SRT be used to indicate whether the ECM has comple ted self-diagnosis of major emission systems and com-
ponents. Completion must be verified in order for the emissions inspection to proceed.
If a vehicle is rejected for a State emissions inspection due to one or more SRT items indicating “INCMP”, use
the information in this Service Manual to set the SRT to “CMPLT”.
In most cases the ECM will automatically complete its self-diagnosis cycle during normal usage, and the SRT
status will indicate “CMPLT” for each application system. Once set as “CMPLT”, the SRT status remains
“CMPLT” until the self-diagnosis memory is erased.
Occasionally, certain portions of the self-diagnostic test may not be completed as a result of the customer's
normal driving pattern; the SRT will indicate “INCMP” for these items.
NOTE:
The SRT will also indicate “INCMP” if the self-diagnosis memory is erased for any reason or if the ECM mem-
ory power supply is interrupted for several hours.
If, during the state emissions inspection, the SRT indicates “CMPLT” for all test items, the inspector will con-
tinue with the emissions test. However, if the SRT i ndicates “INCMP” for one or more of the SRT items the
vehicle is returned to the customer untested.
NOTE:
If permanent DTC is stored or MIL illuminates during the state emissions inspection, the vehicle is also
returned to the customer untested even though the SRT indicates “CMPLT” for all test items. Therefore, it is
important to check SRT (“CMPLT ”), DTC (No DTCs) and permanent DT C (No permanent DTCs) before the
inspection.
SRT Item
The table below shows required self-diagnostic items to set the SRT to “CMPLT”.
*: If completion of several SRTs is required, perform driving patterns (DTC confirmation procedure), one by one based on the pr iority for
models with CONSULT-III.
SRT Set Timing
SRT is set as “CMPLT” after self-diagnosis has been performed one or more times. Completion of SRT is
done regardless of whether the result is OK or NG. T he set timing is different between OK and NG results and
is shown in the table below.

Suggested Maximum Speed in Each Gear
Downshift to a lower gear if the engine is not running smoothly, or if you need to accelerate.
Do not exceed the maximum suggested speed (shown below) in any gear. For level road driving, use the high-
est gear suggested for that speed. Always observe post
ed speed limits and drive according to the road condi-
tions to ensure safe operation. Do not over-rev t he engine when shifting to a lower gear as it may cause
engine damage or loss of vehicle control.
PERMANENT DIAGNOSTIC TROU BLE CODE (PERMANENT DTC)
Permanent DTC is defined in SAE J1979/ISO 15031-5 Service $0A.
ECM stores a DTC issuing a command of turning on MIL as a permanent DTC and keeps storing the DTC as
a permanent DTC until ECM judges that there is no presence of malfunction.
Permanent DTCs cannot be erased by using the Erase function of CONSULT-III or Generic Scan Tool (GST)
and by disconnecting the battery to shut off power to EC M. This prevents a vehicle from passing the state
emission inspection without repairing a malfunctioning part.
When not passing the state emission inspection due to more than one permanent DTC, permanent DTCs
should be erased, referring to this manual.
NOTE:
• The important items in state emission inspection are t hat MIL is not ON, SRT test items are set, and perma-
nent DTCs are not included.
• Permanent DTCs do not apply for regions that permanent DTCs are not regulated by law.
Permanent DTC Item
For permanent DTC items, MIL turns ON. Refer to EC-542, "Emission-related Diagnostic Information", “EMIS-
SION-RELATED DIAGNOSTIC INFORMATION ITEMS”.
Permanent DTC Set Timing
The setting timing of permanent DTC is stored in ECM with the lighting of MIL when a DTC is confirmed.

< SERVICE INFORMATION >[MR18DE]
ON BOARD DIAGNOSTIC (OBD) SYSTEM
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-542, "
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.
