U1000 CAN COMM CIRCUIT

Description

INFOID:0000000008285770

CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independently). In CAN communication, control units are con-
nected 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.

P0717 INPUT SPEED SENSOR A

P0717 INPUT SPEED SENSOR A

Description

INFOID:0000000008285782

The input speed sensor detects input shaft rpm (revolutions per minute). It is located on the input side of the A/
T. Monitors revolution of sensor 1 and sensor 2 for non-standard conditions.

DTC CONFIRMATION PROCEDURE

CAUTION:

Always drive vehicle at a safe speed.

1.

PRECONDITIONING

If “DTC CONFIRMATION PROCEDURE” has been previously conducted, always turn ignition switch OFF and
wait at least 10 seconds before conducting the next test.

>> GO TO 2.

2.

CHECK DTC DETECTION

With CONSULT

1.

Start the engine.

2.

Select “SLCT LVR POSI”, “GEAR”, “VHCL/S SE-A/T”, “CLSD THL POS” and “ENGINE SPEED” in “Data
Monitor” in “TRANSMISSION”.

3.

Drive vehicle and maintain the following conditions for 5 seconds or more.

CAUTION:

Keep the same gear position.
NOTE:
Driving the vehicle uphill (increased engine load) will help maintain the driving conditions required for this
test.

4.

Perform “Self Diagnostic Results” in “TRANSMISSION”.

With GST

Follow the procedure “With CONSULT”.
