6.PATTERN 2
1. Drive the vehicle. And 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.
2. Depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH) again
NOTE:
• Checking the vehicle speed with GST is advised.
• When steady-state driving is performed again even afte r it is interrupted, each diagnosis can be conducted.
In this case, the time required for diagnosis may be extended.
>> GO TO 7.
7.PATTERN 3
• Operate vehicle following the driving pattern shown in the figure.
• Release the accelerator pedal during deceleration of vehicle speed
from 90 km/h (56 MPH) to 0 km/h (0 MPH).
>> GO TO 8.
8.PATTERN 4
• Operate vehicle, following the driving pattern shown in the figure.
- Drive the vehicle in a proper gear at 60 km/h (38 MPH) and main-
tain the speed.
- Release the accelerator pedal fully at least 5 seconds.
- Repeat the above two steps at least 5 times.
>> GO TO 9.
9.PATTERN 5
• The accelerator pedal must be held very steady during steady-state driving.
• If the accelerator pedal is moved, the test must be conducted again.
>> GO TO 10.
10.PATTERN 6
• Cool down the engine so that the engine c oolant temperature lowers between 15 – 35°C (59 – 95 °F).
CAUTION:
Never turn the ignition switch ON while cooling down the engine.
• Engine coolant temperature at engine start is between 15 – 35 °C (59 – 95 °F) and has lowered 45 °C (113 °F)
or more since the latest engine stop.

U0101 CAN COMM CIRCUIT
DescriptionINFOID:0000000009462574
CAN (Controller Area Network) is a serial communication li
ne for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
