HOW TO SET SRT CODE

Work Procedure


1. CHECK DTC

Check DTC.
Is any DTC detected?
YES- Repair malfunction(s) and erase DTC. Refer to "DTC Index" Testing and Inspection.
NO- GO TO 2.

2. CHECK SRT STATUS

With CONSULT
Select "SRT STATUS" in "DTC & SRT CONFIRMATION" mode with CONSULT.
Without CONSULT
Perform "SRT status" mode with "On Board Diagnosis Function" On Board Diagnosis Function.
With GST
Select Service $01 with GST.
Is SRT code(s) set?
YES- GO TO 12.
NO-1- With CONSULT: GO TO 3.
NO-2- Without CONSULT: GO TO 4.

3. DTC CONFIRMATION PROCEDURE

1.Select "SRT WORK SUPPORT" in "DTC & SRT CONFIRMATION" mode with CONSULT.
2.For SRT(s) that is not set, perform the corresponding "DTC CONFIRMATION PROCEDURE" according to the "Performance Priority" in the "SRT ITEM" table. Refer to "Description" Description.
3.Check DTC.
Is any DTC detected?
YES- Repair malfunction(s) and erase DTC. Refer to "DTC Index" Testing and Inspection.
NO- GO TO 11.

4. PERFORM ROAD TEST

- Check the "Performance Priority" in the "SRT ITEM" table. Refer to "Description" Description.
- Perform the most efficient SRT set driving pattern to set the SRT properly. Refer to "SRT Set Driving Pattern" SRT Set Driving Pattern.
In order to set all SRTs, the SRT set driving pattern must be performed at least once.
- GO TO 5.

5. PATTERN 1

1.Check the vehicle condition;
-Engine coolant temperature is 10 to 35�C (14 to 95�F).
-Fuel tank temperature is more than 0�C (32�F).
2.Start the engine.
3.Keep engine idling until the engine coolant temperature is greater than 70�C (158�F)
NOTE:
ECM terminal voltage is follows;
- Engine coolant temperature
-10 to 35�C (14 to 95�F): 3.0 - 4.3 V
- 70 �(158�F): Less than 4.1 V
- Fuel tank temperature: Less than 1.4 V
Refer to "Reference Value" Pinout Values and Diagnostic Parameters.
- GO TO 6.

6. PATTERN 2

1.Drive the vehicle. And depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH), then release the accelerator pedal and keep it released for more than 10 seconds.
2.Depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH) again
NOTE:
- Checking the vehicle speed with GST is advised.
- When steady-state driving is performed again even after it is interrupted, each diagnosis can be conducted.
In this case, the time required for diagnosis may be extended.
- GO TO 7.

7. PATTERN 3






- Operate vehicle following the driving pattern shown in the figure.
- Release the accelerator pedal during deceleration of vehicle speed from 90 km/h (56 MPH) to 0 km/h (0 MPH).
- GO TO 8.

8. PATTERN 4






- Operate vehicle, following the driving pattern shown in the figure.
- Drive the vehicle in a proper gear at 60 km/h (38 MPH) and maintain the speed.
- Release the accelerator pedal fully at least 5 seconds.
- Repeat the above two steps at least 5 times.
- GO TO 9.

9. PATTERN 5

- The accelerator pedal must be held very steady during steady-state driving.
- If the accelerator pedal is moved, the test must be conducted again.
- GO TO 10.

10. PATTERN 6

- Cool down the engine so that the engine coolant temperature lowers between 15 - 35�C (59 - 95�F).

CAUTION:
Never turn the ignition switch ON while cooling down the engine.
- Engine coolant temperature at engine start is between 15 - 35�C (59 - 95�F) and has lowered 45�C (113�F)
or more since the latest engine stop.
- GO TO 11.
