OUTLINE
In order to set all SRTs, the selfdiagnoses as in the "SRT ITEM" table must have been performed at least once. Each diagnosis may require actual driving for a long period of time under various conditions.
SRT ITEM
The table below shows required selfdiagnostic items to set the SRT to "CMPLT".
SRT item*1 (CONSULT indication) | Performance Priority*2 | Required selfdiagnostic items to set the SRT to "CMPLT" | Corresponding DTC No. |
CATALYST | 1 | Three way catalyst function | P0420 |
EVAP SYSTEM | 1 | EVAP control system purge flow monitoring | P0441 |
1 | EVAP control system | P0445 | |
HO2S | 1 | Heated oxygen sensor 2 | P0137 |
Heated oxygen sensor 2 | P0138 | ||
Heated oxygen sensor 2 | P0139 | ||
EGR/VVT SYSTEM | 2 | Intake value timing control function | P0011 |
*1: Though displayed on the CONSULT screen, "HO2S HTR" is not SRT item.
*2: If completion of several SRTs is required, perform driving patterns (DTC confirmation procedure), one by one based on the priority for models with CONSULT.
SRT SERVICE PROCEDURE
If a vehicle has failed the state emissions inspection due to one or more SRT items indicating "INCMP", review the flowchart diagnostic sequence, referring to the following flowchart.
SRT Set Driving Pattern
CAUTION: Always drive the vehicle in safe manner according to traffic conditions and obey all traffic laws.
*1: 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.
*2: Checking the vehicle speed with GST is advised.
*: Normal conditions
NOTE: Diagnosis is performed as quickly as possible under normal conditions. However, under other conditions, diagnosis may also be performed. [For example: ambient air temperature other than 20 - 30C (68 - 86F)]
1.CHECK DTC
Check DTC.
Is any DTC detected?
YES >> Repair malfunction(s) and erase DTC. Refer to EC85, "DTC Index".
NO >> GO TO 2.
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 EC58, "On Board Diagnosis Function".
WITH GST
Select Service $01 with GST.
Is SRT code(s) set?
YES >> GO TO 11.
NO1 >> With CONSULT: GO TO 3.
NO2 >> Without CONSULT: GO TO 4.
3.DTC CONFIRMATION PROCEDURE
Is any DTC detected?
YES >> Repair malfunction(s) and erase DTC.
NO >> GO TO 11.
4.PERFORM ROAD TEST
>> GO TO 5.
5.PATTERN 1
NOTE: ECM terminal voltage is follows;
>> GO TO 6.
6.PATTERN 2
NOTE:
In this case, the time required for diagnosis may be extended.
>> GO TO 7.
7.PATTERN 3
- 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
- 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
>> GO TO 10.
10.PATTERN 6
>> GO TO 11.
11.CHECK SRT STATUS
WITH CONSULT
Select "SRT STATUS" in "DTC & SRT CONFIRMATION" mode of "ENGINE" using CONSULT.
WITHOUT CONSULT
Perform "SRT status" mode with EC, "On Board Diagnosis Function".
WITH GST
Select Service $01 with GST.
Is SRT(s) set?
YES >> GO TO 12.
NO >> Call TECH LINE or take appropriate action.
12.CHECK PERMANENT DTC
NOTE: Permanent DTC cannot be checked with a tool other than CONSULT or GST.
WITH CONSULT
Select "SRT STATUS" in "DTC & SRT CONFIRMATION" mode of "ENGINE" using CONSULT.
WITH GST
Select Service $01 with GST.
Is permanent DTC(s) detected?
