●
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 59 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 59 and ground is lower than 1.4V).
●
The engine is started at the tank fuel temperature of warmer than 0
°C (32°F) (where the voltage
between the ECM terminal 60 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:
●
The driving pattern outlined in *2 must be repeated at least 3 times.
Pattern 4:
●
Tests are performed after the engine has been operated for at least 17 minutes.
●
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: Operate the vehicle in the following driving pattern.
1.
Decelerate vehicle to 0 km/h (0 MPH) and let engine idle.
2.
Repeat driving pattern shown below at least 10 times.
–
During acceleration, hold the accelerator pedal as steady as
possible.
*3: Checking the vehicle speed with CONSULT-II or GST is advised.
Suggested Transmission Gear Position for A/T Models
Set the selector lever in the D position with the overdrive switch turned ON.
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.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
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 safe 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 Mode 6 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.
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)]:

HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION
How to Erase DTC
With CONSULT-II
NOTE:
If the DTC is not for A/T related items (see
), skip steps 2 through 4.
1.
If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 5
seconds and then turn it ON (engine stopped) again.
2.
Turn CONSULT-II “ON” and touch “A/T”.
3.
Touch “SELF-DIAG RESULTS”.
4.
Touch “ERASE”. [The DTC in the TCM (Transmission control module) will be erased.] Then touch “BACK”
twice.
5.
Touch “ENGINE”.
6.
Touch “SELF-DIAG RESULTS”.
7.
Touch “ERASE”. (The DTC in the ECM will be erased.)

●
If DTCs are displayed for both ECM and TCM (Transmission control module), they need to be erased indi-
vidually from the ECM and TCM (Transmission control module).
The emission related diagnostic information in the ECM can be erased by selecting “ERASE” in the “SELF-
DIAG RESULTS” mode with CONSULT-II.
With GST
The emission related diagnostic information in the ECM can be erased by selecting Mode 4 with GST.
NOTE:
If the DTC is not for A/T related items (see
), skip step 2.
1.
If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 5
seconds and then turn it ON (engine stopped) again.
2.
Perform
. (The DTC in TCM will be erased.)
3.
Select MODE 4 with GST (Generic Scan Tool).
●
If the battery is disconnected, the emission-related diagnostic information will be lost within 24
hours.
●
The following data are cleared when the ECM memory is erased.
–
Diagnostic trouble codes
–
1st trip diagnostic trouble codes
–
Freeze frame data
–
1st trip freeze frame data
–
System readiness test (SRT) codes
–
Test values
–
Others
Actual work procedures are explained using a DTC as an example. Be careful so that not only the DTC, but all
of the data listed above, are cleared from the ECM memory during work procedures.
