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 (PART 1)
With CONSULT-III
Turn ignition switch ON.
Select "DATA MONITOR".
Check that output voltage of CVT fluid temperature sensor is within the range specified below.
Diagnosis Procedure 1.CHECK CVT FLUID TEMPERATURE SENSOR CIRCUIT
Turn ignition switch OFF.
Disconnect TCM harness connector.
Check resistance between TCM harness connector F16 terminal 13 and 25.
Is the Inspection result normal?
YES >> GO TO 5.
NO >> GO TO 2. 2.CHECK HARNESS BETWEEN TCM AND CVT UNIT (CVT TEMPERATURE SENSOR) (PART 1)
Disconnect CVT unit harness connector.
Check continuity between TCM harness connector F16 (A) terminal 13, 25 and CVT unit harness connector F46 (B) terminal 17, 19.
Is the Inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace damaged parts. 3.CHECK HARNESS BETWEEN TCM AND CVT UNIT (CVT TEMPERATURE SENSOR) (PART 2)
Check continuity between TCM harness connector F16 terminal 13, 25 and ground.
