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
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 LINE PRESSURE SOLENOID VALVE
3.CHECK SECONDARY SPEED SENSOR SYSTEM
Check secondary speed sensor system. Refer to TM-60, "DTC Logic".
4.CHECK PRIMARY SPEED SENSOR SYSTEM
Check primary speed sensor system. Refer to TM-57, "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.
