HOW TO SET SRT CODE

Description

INFOID:0000000009947188

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”.

*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.

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” 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”.
