DescriptionINFOID:0000000005397913
• The secondary pressure solenoid valve is included in the control valve assembly.
• The secondary pressure solenoid valve regulates the secondary pressure to suit the driving condition in
response to a signal sent from the TCM.
CONSULT-III Reference Val ue in Data Monitor ModeINFOID:0000000005397914
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000005397915
• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0868” with CONSULT-III is det ected when secondary fluid pressure is too low
compared with the commanded value while driving.
Possible CauseINFOID:0000000005397916
• Harness or connectors (Solenoid circuit is open or shorted.)
• Secondary pressure solenoid valve system
• Secondary pressure sensor
• Line pressure control system
DTC Confirmation ProcedureINFOID:0000000005397917
CAUTION:
Always drive vehicle at a safe speed.
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. Make sure that output voltage of CVT fluid temperature sensor is within the range below.
ATF TEMP SEN: 1.0 - 2.0 V
If out of range, drive the vehicle to decrease the voltage (warm up the fluid) or stop engine to
increase the voltage (c ool down the fluid)
3. Start engine and maintain the following conditions for at least 10 consecutive seconds. VEHICLE SPEED (accelerate slowly): 0 → 50 km/h (31 MPH)
ACC PEDAL OPEN: 0.5/8 - 1.0/8
RANGE: “D” position
4. If DTC is detected, go to CVT-111, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000005397918
1.CHECK INPUT SIGNAL
With CONSULT-III
1. Start engine.
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
