Diagnostic Test
- CHECK DTC
Check DTC.
Is any DTC detected?
YES
Repair malfunction(s) and erase DTC. Refer to DTC INDEX .
NO
GO TO STEP 2 .
- CHECK SRT STATUS
WITH CONSULT
Select "SRT STATUS" in "DTC & SRT CONFIRMATION" mode of "ENGINE" using CONSULT.
WITHOUT CONSULT
Perform "SRT status" mode with ON BOARD DIAGNOSIS FUNCTION .
WITH GST
Select Service $01 with GST.
Is SRT code(s) set?
YES
GO TO STEP 12 .
NO-1
With CONSULT: GO TO STEP 3 .
NO-2
Without CONSULT: GO TO STEP 4 .
- DTC CONFIRMATION PROCEDURE
- Select "SRT WORK SUPPORT" in "DTC & SRT CONFIRMATION" mode with CONSULT.
- 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 SYSTEM READINESS TEST (SRT) CODE .
- Check DTC.
Is any DTC detected?
YES
Repair malfunction(s) and erase DTC. Refer to DTC INDEX .
NO
GO TO STEP 11 .
- PERFORM ROAD TEST
- Check the "Performance Priority" in the "SRT ITEM" table. Refer to SYSTEM READINESS TEST (SRT) CODE .
- Perform the most efficient SRT set driving pattern to set the SRT properly. Refer to SRT SET DRIVING PATTERN .
In order to set all SRTs, the SRT set driving pattern must be performed at least once.
GO TO STEP 5 .
- PATTERN 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).
- Start the engine.
- 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 1.4 V
- Fuel tank temperature: Less than 4.1 V
Refer to REFERENCE VALUE .
GO TO STEP 6 .
- Check the vehicle condition;
- PATTERN 2
- 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.
- 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 STEP 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 STEP 8 .
- Operate vehicle following the driving pattern shown in the figure.
- 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 STEP 9 .
- Operate vehicle following the driving pattern shown in the figure.
- 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 STEP 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 STEP 11 .
- Cool down the engine so that the engine coolant temperature lowers between 15 - 35°C (59 - 95°F).
- CHECK SRT STATUS
Select "SRT STATUS" in "DTC & SRT CONFIRMATION" mode of "ENGINE" using CONSULT.
Perform "SRT status" mode with ON BOARD DIAGNOSIS FUNCTION .
Select Service $01 with GST.
Is SRT(s) set?
YES
GO TO STEP 12 .
NO
Call TECH LINE or take appropriate action.
- CHECK PERMANENT DTCNOTE:
Permanent DTC cannot be checked with a tool other than CONSULT or GST.
Select "SRT STATUS" in "DTC & SRT CONFIRMATION" mode of "ENGINE" using CONSULT.
Select Service $01 with GST.
Is permanent DTC(s) detected?
YES
Proceed to DESCRIPTION .
NO
