DTC CONFIRMATION PROCEDURE
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
Turn ignition switch ON.
Start engine and wait at least 5 seconds.
Perform "SELF-DIAG RESULTS" mode for "TRANSMISSION". With GST
Diagnosis Procedure 1.CHECK PRESSURE CONTROL SOLENOID VALVE A (LINE PRESSURE SOLENOID VALVE) CIRCUIT
Turn ignition switch OFF.
Disconnect TCM harness connector.
Check resistance between TCM harness connector F16 terminal 40 and ground.
Is the Inspection result normal?
YES >> GO TO 5.
NO >> GO TO 2. 2.CHECK HARNESS BETWEEN TCM AND CVT UNIT [PRESSURE CONTROL SOLENOID VALVE A (LINE PRESSURE SOLENOID VALVE)] (PART 1)
Disconnect CVT unit connector.
Check continuity between TCM harness connector F16 (A) terminal 40 and CVT unit harness connector F46 (B) terminal 2.
Is the Inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace damaged parts. 3.CHECK HARNESS BETWEEN TCM AND CVT UNIT [PRESSURE CONTROL SOLENOID VALVE A (LINE PRESSURE SOLENOID VALVE)] (PART 2)
Check continuity between TCM vehicle side harness connector F16 terminal 40 and ground.
