How to Set SRT Code

To set all SRT codes, self-diagnosis for the items indicated above must be performed one or more times.
Each diagnosis may require a long period of actual driving under various conditions.
WITH CONSULT-III
Perform corresponding DTC Confirmation Procedure one by one based on Performance Priority in the table on "SRT Item".
WITHOUT CONSULT-III
The most efficient driving pattern in which SRT codes can be properly set is explained below. The driving pattern should be performed one or more times to set all SRT codes.

DRIVING PATTERN

• 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 shortest.

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) ], diagnosis may also be performed.

Pattern 1:

• The engine is started at the engine coolant temperature of -10 to 35°C (14 to 95°F)(where the voltage between the ECM terminal 46 and ground is 3.0 - 4.3 V).
• The engine must be operated at idle speed until the engine coolant temperature is greater than 70°C (158°F) (where the voltage between the ECM terminal 46 and ground is lower than 1.4 V).
• The engine is started at the fuel tank temperature of warmer than 0°C (32°F) (where the voltage between the ECM terminal 95 and ground is less than 4.1 V). Pattern 2:
• 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.

Pattern 3:
