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)

  

  1. Start engine.
  2. Check voltage between TCM harness connector F16 terminal 25 and 26.

  

  

  1. If OK, check the pulse when vehicle cruises.

  

Is the Inspection result normal?
OK >> GO TO 7.
NG - 1 >> Battery voltage is not supplied: GO TO 2.
NG - 2 >> Battery voltage is supplied, but there is a malfunction in the frequency: GO TO 4.

  1. CHECK HARNESS BETWEEN TCM AND CVT UNIT HARNESS CONNECTOR (SENSOR POWER AND SENSOR GROUND) (PART 1)

  

  1. Turn ignition switch OFF.
  2. Disconnect TCM harness connector and CVT unit harness connector.
  3. Check continuity between TCM harness connector F16 (A) terminal 25 and 26 and CVT unit harness connector F46 (B) terminal 19 and 20.

  

Is the Inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace damaged parts.

  1. CHECK HARNESS BETWEEN TCM AND CVT UNIT HARNESS CONNECTOR (SENSOR POWER AND SENSOR GROUND) (PART 2)

  

Check continuity between TCM harness connector F16 terminal 25 and 26 and ground.

  

Is the Inspection result normal?
YES >> GO TO 6.
NO >> Repair or replace damaged parts.

  1. CHECK HARNESS BETWEEN TCM AND CVT UNIT HARNESS CONNECTOR [INPUT SPEED SENSOR (PRIMARY SPEED SENSOR)] (PART 1)

  

  1. Turn ignition switch OFF.
  2. Disconnect TCM harness connector and CVT unit harness connector.
  3. Check continuity between TCM harness connector F16 (A) terminal 33 and CVT unit harness connector F46 (B) terminal 22.

  

Is the Inspection result normal?
YES >> GO TO 5.
NO >> Repair or replace damaged parts.

  1. CHECK HARNESS BETWEEN TCM AND CVT UNIT HARNESS CONNECTOR [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 6.
>> Repair or replace damaged parts.

  1. CHECK THE TCM SHORT Replace same type TCM, perform self-diagnosis check. Erase self-diagnostic results and then drive the vehicle [10 km/h (6 MPH) or more], perform self-diagnosis check. Refer to DTC Logic.

Is the "P0715 INPUT SPD SEN/CIRC" detected again?
YES >> GO TO 7.
NO >> Check intermittent incident. Refer to See: Testing and Inspection\Initial Inspection and Diagnostic Overview\Service Information For Electrical Incident\Intermittent Incident.
7.DETECT MALFUNCTIONING ITEMS
Check TCM connector pin terminals for damage or loose connection with harness connector.
Is the Inspection result normal?
YES >> Replace TCM. Refer to See: Powertrain Management\Transmission Control Systems\Control Module, CVT\Service and Repair\CVT RE0F09B\Exploded View.
NO >> Repair or replace damaged parts.
