ON BOARD DIAGNOSTIC (OBD) SYSTEM
●
The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driv-
ing 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)], diag-
nosis 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 73 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 73 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 107 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 con-
ducted. In this case, the time required for diagnosis may be extended.
Pattern 3:
●
Operate vehicle following the driving pattern shown in the figure.
●
Release the accelerator pedal during decelerating vehicle speed
from 90 km/h (56 MPH) to 0 km/h (0 MPH).
Pattern 4:
●
The accelerator pedal must be held very steady during steady-
state driving.
●
If the accelerator pedal is moved, the test must be conducted all
over again.
*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.
Suggested Transmission Gear Position for A/T Models
Set the selector lever in the D position.
Suggested Upshift Speeds for M/T Models
Shown below are suggested vehicle speeds for shifting into a higher gear. These suggestions relate to fuel
economy and vehicle performance. Actual upshift speeds will vary according to road conditions, the weather
and individual driving habits.
PBIB2244E
For normal acceleration in low altitude areas
[less than 1,219 m (4,000 ft)]:
For quick acceleration in low altitude
areas and high altitude areas
[over 1,219 m (4,000 ft)]:

Suggested Maximum Speed in Each Gear
Downshift to a lower gear if the engine is not running smoothly, or if you need to accelerate.
Do not exceed the maximum suggested speed (shown below) in any gear. For level road driving, use the high-
est gear suggested for that speed. Always observe posted speed limits and drive according to the road condi-
tions to ensure sage operation. Do not over-rev the engine when shifting to a lower gear as it may cause
engine damage or loss of vehicle control.
TEST VALUE AND TEST LIMIT (GST ONLY — NOT APPLICABLE TO CONSULT-II)
The following is the information specified in Service $06 of SAE J1979.
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.
