DTC CONFIRMATION PROCEDURE
CAUTION: Always drive vehicle at a safe speed.
NOTE: Immediately after performing any "DTC CONFIRMATION PROCEDURE", always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
1.CHECK DTC DETECTION
With CONSULT
- Turn ignition switch ON.
- Select "Data Monitor" in "TRANSMISSION".
- Start engine and maintain the following conditions for at least 30 consecutive seconds.
ATF TEMP SEN : 1.0 − 2.0 V
ACC PEDAL OPEN : More than 1.0/8
RANGE : "D" position
VEHICLE SPEED : 10 km/h (6 MPH) 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".
Diagnosis Procedure
1.CHECK LINE PRESSURE
Perform line pressure test. Refer to TM-162, "Inspection and Judgment".
2.CHECK SECONDARY PRESSURE SOLENOID VALVE
- Turn ignition switch OFF.
- Disconnect CVT unit connector.
- Check secondary pressure solenoid valve. Refer to TM-76, "Component Inspection (Secondary Pressure Solenoid Valve)".
3.CHECK LINE PRESSURE SOLENOID VALVE
Check line pressure solenoid valve. Refer to TM-76, "Component Inspection (Line Pressure Solenoid Valve)".
4.CHECK SECONDARY PRESSURE SENSOR SYSTEM
Check secondary pressure sensor system. Refer to TM-85, "DTC Logic".
5.DETECT MALFUNCTIONING ITEMS
Check TCM connector pin terminals for damage or loose connection with harness connector.
Component Inspection (Line Pressure Solenoid Valve)
1.CHECK LINE PRESSURE SOLENOID VALVE
Check resistance between CVT unit connector terminal and ground.
Component Inspection (Secondary Pressure Solenoid Valve)
1.CHECK SECONDARY PRESSURE SOLENOID VALVE
Check resistance between CVT unit connector terminal and ground.
