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 SERVICE PROCEDURE

SRT Set Driving Pattern

CAUTION: Always drive the vehicle in safe manner according to traffic conditions and obey all traffic laws.

SRT Set Driving Pattern

*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.

  • The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving habits, etc.
  • "Zone A" is the fastest time where required for the diagnosis under normal conditions*. If the diagnosis is not completed within "Zone A", the diagnosis can still be performed within "Zone B".

*: Normal conditions

  • Sea level
  • Flat road
  • Ambient air temperature: 20 - 30C (68 - 86F)

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)]
