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
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”.
Is “P0715” detected?
YES
>> Go to
NO
>> Check intermittent incident. Refer to
GI-41, "Intermittent Incident"
.
Diagnosis Procedure
INFOID:0000000010113602
Regarding Wiring Diagram information, refer to
.
1.
CHECK PRIMARY SPEED SENSOR
1. Start engine.
2. Check voltage between TCM connector terminals.

Possible cause
P0715
Input/Turbine Speed Sensor
A Circuit
• 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.)
• Primary speed sensor
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.

3. If OK, check the pulse when vehicle drive.
Is the inspection result normal?
YES
>> GO TO 7.
NO - 1 >> Battery voltage is not supplied: GO TO 2.
NO - 2 >> Battery voltage is supplied, but there is a malfunction in
the frequency: GO TO 4.
2.
CHECK HARNESS BETWEEN TCM AND CVT UNIT HARNESS CONNECTOR (SENSOR POWER AND
SENSOR GROUND) (PART 1)
1. Turn ignition switch OFF.
2. Disconnect TCM connector and CVT unit connector.
3. Check continuity between TCM vehicle side harness connector
terminals and CVT unit vehicle side harness connector termi-
nals.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair or replace damaged parts.
3.
CHECK HARNESS BETWEEN TCM AND CVT UNIT HARNESS CONNECTOR (SENSOR POWER AND
SENSOR GROUND) (PART 2)
Check continuity between TCM vehicle side harness connector ter-
minals and ground.
Is the inspection result normal?
YES
>> GO TO 6.
NO
>> Repair or replace damaged parts.
