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 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.

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 - 4.3V).

• 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 1.4V).

• 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 4.1V).

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.

Test Value and Test Limit

INFOID:0000000001161996

The following is the information specified in Service $06 of ISO 15031-5.
The test value is a parameter used to determine whether a system/circuit diagnostic test is OK or NG while
being monitored by the ECM during self-diagnosis. The test limit is a reference value which is specified as the
maximum or minimum value and is compared with the test value being monitored.
These data (test value and test limit) are specified by Test ID (TID) and Component ID (CID) and can be dis-
played on the GST screen.
