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.
Perform the following procedure to confirm the malfunction is eliminated after the repair.
1.
CHECK DTC DETECTION
With CONSULT-III
1.
Turn ignition switch ON.
2.
Select “Data Monitor” mode for “TRANSMISSION”.
3.
Start engine and maintain the following conditions for at least 10 consecutive seconds. Test start from 0
km/h (0 MPH).
With GST
Follow the procedure “With CONSULT-III”.
Is “P0746 PRS CNT SOL/A FCTN” detected?
YES
>> Go to
NO
>> Check intermittent incident. Refer to
GI-35, "Intermittent Incident"
.
Diagnosis Procedure
INFOID:0000000003806421
1.
CHECK LINE PRESSURE
Perform line pressure test. Refer to
TM-308, "Inspection and Judgment"
.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair or replace damaged parts. Refer to
TM-308, "Inspection and Judgment"
.
2.
CHECK PRESSURE CONTROL SOLENOID VALVE A (LINE PRESSURE SOLENOID VALVE)
Check pressure control solenoid valve A (line pressure solenoid valve). Refer to
tion [Pressure Control Solenoid Valve A (Line Pressure Solenoid Valve)]"
.

PRS CNT SOL/A FCTN
Unexpected gear ratio was de-
tected in the low side due to ex-
cessively low line pressure.
• Line pressure control system
• Output speed sensor (sec-
ondary speed sensor)
• Input speed sensor (primary
speed sensor)
