• The step motor's 4 aspects of ON/OFF change according to the signal from TCM. As a result, the flow of line pressure to primary pulley is changed and pulley ratio is controlled.
• This diagnosis item is detected when electrical system is OK, but mechanical system is NG.
• This diagnosis item is detected when the state of the changing the speed mechanism in unit does not oper- ate normally.
CONSULT-III Reference Val ue in Data Monitor ModeINFOID:0000000005397969
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000005397970
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P1778” with CONSULT-III is detected under the following conditions.
- When not changing the pulley ratio according to the instruction of TCM.
Possible CauseINFOID:0000000005397971
Step motor
DTC Confirmation ProcedureINFOID:0000000005397972
CAUTION:
• Always drive vehicle at a safe speed.
• Before starting “DTC Confirmation Procedure”, confirm “Hi” or “Mid” or “Low” fixation by “PRI
SPEED” and “VEHICLE SPEED” on “DATA MONITOR MODE”.
• If hi-geared fixation occurred, go to CVT-134, "
Diagnosis Procedure".
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, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm 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. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
4. Start engine and maintain the following conditions for at least 30 consecutive seconds. TEST START FROM 0 km/h (0 MPH)
CONSTANT ACCELERATION: Keep 30 sec or more
VEHICLE SPEED: 10 km/h (6 MPH) or more
ACC PEDAL OPEN: More than 1.0/8
RANGE: “D” position
ENG SPEED: 450 rpm or more
5. If DTC is detected, go to CVT-134, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.

DescriptionINFOID:0000000005397994
WITH INTELLIGENT KEY
• The mechanical key interlock mechanism also operates as a shift lock: With the ignition knob switch turned to ON, selector lever cannot be shifted from “P” position to any other
position unless brake pedal is depressed.
With the ignition knob switch turned to OFF, selector lever cannot be shifted from “P” position to any other
position.
• The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole- noid and by the operation of the ignition knob switch, respectively.
WITHOUT INTELLIGENT KEY
• The mechanical key interlock mechanism also operates as a shift lock:With the ignition switch turned to ON, selector lever cannot be shifted from “P” position to any other position
unless brake pedal is depressed.
With the key removed, selector lever cannot be shifted from “P” position to any other position.
The key cannot be removed unless selector lever is placed in “P” position.
• The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and sli der located inside key cylinder, respectively.
