U1000 CAN COMM CIRCUIT
COMPONENT DIAGNOSIS
U1000 CAN COMM CIRCUIT
Description
INFOID:0000000003306007
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 independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H and CAN-L) allowing a high rate of information transmission with
less wiring. Each control unit transmits/receives data but selectively reads required data only.

P0715 INPUT SPEED SENSOR (PRI SPEED SENSOR)
P0715 INPUT SPEED SENSOR (PRI SPEED SENSOR)
Description
INFOID:0000000003317779
The input speed sensor (primary speed sensor) detects the primary pulley revolution speed and sends a sig-
nal to the TCM.
DTC Logic

DTC CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
Immediately after performing any “DTC CONFIRMATION PROCEDURE”, always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
1.
CHECK DTC DETECTION
With CONSULT-III
1.
Turn ignition switch ON.
2.
Select “Data Monitor” in “TRANSMISSION”.
3.
Start engine and maintain the following conditions for at least 5 consecutive seconds.
With GST
Follow the procedure “With CONSULT-III”.
Is “P0715 INPUT SPD SEN/CIRC” detected?
YES
>> Go to
NO
>> Check intermittent incident. Refer to
GI-40, "Intermittent Incident"
.
Diagnosis Procedure
INFOID:0000000003317781
1.
CHECK INPUT SPEED SENSOR (PRIMARY SPEED SENSOR)
1.
Start engine.
2.
Check voltage between TCM connector terminals.
3.
If OK, check the pulse when vehicle drive.

P0715
INPUT SPD SEN/CIRC
• Input speed sensor (primary speed sen-
sor) signal is not input due to an open cir-
cuit.
• An unexpected signal is input when vehi-
cle is being driven.
• Harness or connectors
(Sensor circuit is open or shorted.)
• Input speed sensor (primary speed sen-
sor)
VEHICLE SPEED
: 10 km/h (6 MPH) or more
ACC PEDAL OPEN
: More than 1.0/8
RANGE
: “D” position
ENG SPEED
: 450 rpm or more
Driving location
: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
