DTC CONFIRMATION PROCEDURE

CAUTION:
Always drive vehicle at a safe speed.

NOTE:
If "DTC CONFIRMATION PROCEDURE" has been previously performed, 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".
  3. Start engine and maintain the following conditions for at least 5 consecutive seconds.

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.

With GST
Follow the procedure "With CONSULT-III".
Is "P0715 INPUT SPD SEN/CIRC" detected?
YES >> Go to Diagnosis Procedure.
NO >> Check intermittent incident. Refer to See: Testing and Inspection\Initial Inspection and Diagnostic Overview\Service Information For Electrical Incident\Intermittent Incident.

Diagnosis Procedure
1.CHECK INPUT SPEED SENSOR (PRIMARY SPEED SENSOR)
With CONSULT-III

  

  1. Start engine.
  2. Check voltage between TCM harness connector F16 terminal 25, 46 and 25, 48.

  

  

  1. If OK, check pulse when vehicle cruises.

  

Is the Inspection result normal?
YES >> GO TO 12.
NO >> GO TO 2.
2.CHECK POWER AND SENSOR GROUND

  

  1. Turn ignition switch OFF.
  2. Disconnect input speed sensor (primary speed sensor) harness connector.
  3. Turn ignition switch ON.
  4. Check voltage between input speed sensor (primary speed sensor) harness connector F8 terminal 1 and 3.

  

  

  1. Check voltage between input speed sensor (primary speed sensor) harness connector F8 terminal 3 and ground.

  

Is the Inspection result normal?
YES >> GO TO 3.
NO-1 >> Battery voltage is not supplied between terminals 1 and
3, terminal 3 and ground: GO TO 6.
NO-2 >> Battery voltage is not supplied between terminals 1 and 3 only: GO TO 8.
3.CHECK HARNESS BETWEEN TCM AND INPUT SPEED SENSOR (PRIMARY SPEED SENSOR) (SENSOR GROUND)

  

  1. Turn ignition switch OFF.
  2. Disconnect TCM harness connector and CVT unit harness connector.
  3. Check continuity between TCM harness connector F16 terminal 33 and ground.

  

Is the Inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace damaged parts.
4.CHECK HARNESS BETWEEN TCM AND INPUT SPEED SENSOR (PRIMARY SPEED SENSOR) (PART
1)

  

Check continuity between TCM harness connector F16 (A) terminal
33 and input speed sensor (primary speed sensor) harness connector F8 (B) terminal 2.

  

Is the Inspection result normal?
YES >> GO TO 5.
NO >> Repair or replace damaged parts.
5.CHECK HARNESS BETWEEN TCM AND INPUT SPEED SENSOR (PRIMARY SPEED SENSOR) (PART
2)

  

Check continuity between TCM harness connector F16 terminal 33 and ground.

  

Is the Inspection result normal?
YES >> GO TO 10.
NO >> Repair or replace damaged parts.
6.CHECK HARNESS BETWEEN IPDM E/R AND INPUT SPEED SENSOR (PRIMARY SPEED SENSOR)
(POWER) (PART 1)

  

  1. Turn ignition switch OFF.
  2. Disconnect IPDM E/R connector F10.
  3. Check continuity between IPDM E/R harness connector F10 terminal 58 and input speed sensor (primary speed sensor) harness connector F8 terminal 3.

  

Is the Inspection result normal?
YES >> GO TO 7.
NO >> Repair or replace damaged parts.
7.CHECK HARNESS BETWEEN IPDM E/R AND INPUT SPEED SENSOR (PRIMARY SPEED SENSOR)
(POWER) (PART 2)

  

Check continuity between IPDM E/R harness connector F10 terminal 58 and ground.

  

Is the Inspection result normal?
YES >> Check the following.

  • Harness for short or open between ignition switch and IPDM E/R
  • 10A fuse (No. 34, located in IPDM E/R)
  • Ignition switch NO >> Repair or replace damaged parts.

8.CHECK HARNESS BETWEEN TCM AND INPUT SPEED SENSOR (PRIMARY SPEED SENSOR) (SENSOR GROUND) (PART 1)

  

  1. Turn ignition switch OFF.
  2. Disconnect TCM connector.
  3. Check continuity between TCM harness connector F16 terminal 25 (A) and input speed sensor (primary speed sensor) harness connector F8 (B) terminal 1.

  

Is the Inspection result normal?
YES >> GO TO 9.
NO >> Repair or replace damaged parts.
9.CHECK HARNESS BETWEEN TCM AND INPUT SPEED SENSOR (PRIMARY SPEED SENSOR) (SENSOR GROUND) (PART 2)

  

  1. Disconnect CVT unit harness connector.
  2. Check continuity between TCM harness connector F16 terminal 25 and ground.

  

Is the Inspection result normal?
YES >> GO TO 10.
NO >> Repair or replace damaged parts.
10.CHECK CVT UNIT CIRCUIT

  

Check continuity between CVT unit harness connector F46 terminal
19 and ground.

  

Is the Inspection result normal?
YES >> GO TO 11.
NO >> Repair or replace damaged parts.
11.CHECK TCM

  1. Replace same type TCM. Refer to See: Powertrain Management\Transmission Control Systems\Control Module, CVT\Service and Repair\CVT RE0F10A\Exploded View.
  2. Connect each connector.
  3. Perform "DTC CONFIRMATION PROCEDURE". Refer to DTC Logic. Is "P0715 INPUT SPD SEN/CIRC" detected?

YES >> Replace input speed sensor (primary speed sensor). Refer to See: Powertrain Management\Transmission Control Systems\Transmission Speed Sensor, CVT\Service and Repair\Primary Speed Sensor\Removal And Installation.
