DTC CONFIRMATION PROCEDURE
CAUTION:
Be careful of the driving speed.
1.PREPARATION BEFORE WORK
If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.
>> GO TO 2.
2.CHECK DTC DETECTION
Selector lever : “L” POSITION
Vehicle speed : 40 km/h (25 MPH) or more
Is “P0715” detected? YES >> Go to TM-178, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK PRIMARY SPEED SENSOR POWER CIRCUIT
Is the check result normal? YES >> GO TO 2.
NO >> GO TO 6.
2.CHECK PRIMARY SPEED SENSOR GROUND CIRCUIT
Check continuity between primary speed sensor harness connector terminal and ground.
Is the check result normal? YES >> GO TO 3.
NO >> Repair or replace malfunctioning parts
3.CHECK CIRCUIT BETWEEN PRIMARY SPEED SENSOR AND TCM (PART 1)
Is the check result normal? YES >> GO TO 4.
NO >> Repair or replace malfunctioning parts.
4.CHECK CIRCUIT BETWEEN PRIMARY SPEED SENSOR AND TCM (PART 2)
Check continuity between primary speed sensor harness connector terminal and ground.
Is the check result normal? YES >> GO TO 5.
NO >> Repair or replace malfunctioning parts.
5.Check TCM Input signals
Is the check result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace primary speed sensor. Refer to TM-268, "Removal and Installation".
6.DETECT MALFUNCTIONING ITEMS
Check the following items:
Is the check result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Repair or replace malfunctioning parts.
