• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0745” with CONSULT-III is detected under the following conditions.
- TCM detects an improper voltage drop when it tries to operate the solenoid valve.
- When TCM compares target value with monitor value and detects an irregularity.
Possible CauseINFOID:0000000005397875
• Harness or connectors
(Solenoid circuit is open or shorted.)
• Line pressure solenoid valve
DTC Confirmation ProcedureINFOID:0000000005397876
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MO NITOR” mode for “TRANSMISSION” with CONSULT-III.
2. Start engine and wait at least 5 seconds.
3. If DTC is detected, go to CVT-93, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.

firm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MONI TOR” mode for “TRANSMISSION” with CONSULT-III.
2. Start engine and maintain the following conditions for at least 10 consecutive seconds. Test start from 0
km/h (0 MPH).
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) More than
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
3. If DTC is detected, go to CVT-96, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
Diagnosis ProcedureINFOID:0000000005397885
1.CHECK LINE PRESSURE
Perform line pressure test. Refer to CVT-37, "
Inspections before Trouble Diagnosis".
