OUTLINE
In order to set all SRTs, the self-diagnoses 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 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 priority for
models with CONSULT-III.
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.

HOW TO SET SRT CODE
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.
• The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving
habits, etc.
Zone A refers to the range where the time, required for the diagnosis under normal conditions*, is the short-
est.

Zone B refers to the range where the diagnosis can still be performed if the diagnosis is not completed within
zone A.
*: Normal conditions refer to the following:
• Sea level
• Flat road
• Ambient air temperature: 20 - 30
°C (68 - 86°F)
• Diagnosis is performed as quickly as possible under normal conditions.
Under different conditions [For example: ambient air temperature other than 20 - 30
°C (68 - 86°F)], diagno-
sis may also be performed.
