P1778 STEP MOTOR - FUNCTION
DescriptionINFOID:0000000003806475
 The step motor changes the step by turning 4 coils ON/OFF 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 the electrical system is OK, but the mechanical system is NG.
 This diagnosis item is detected when the state of the changing of the speed mechanism in the unit does not
operate normally.

INSTALLATION
1. Align ∆ marking on CVT unit harness connector terminal body
with o marking on bayonet ring. Insert CVT unit harness connec-
tor. Then rotate bayonet ring clockwise.
2. Rotate bayonet ring clockwise until ∆ marking on CVT unit har-
ness connector terminal body is aligned with the slit on bayonet
ring as shown in the figure (correctly fitting condition). Install
CVT unit harness connector to CVT unit harness connector ter-
minal body.
CAUTION:
 Securely align ∆ marking on CVT unit harness connector
terminal body with bayonet ring slit. Then, be careful not
to make a half fit condition as shown in the figure.
 Never mistake the slit of bayonet ring for other dent por-
tion.

< PRECAUTION >[CVT: RE0F10A]
PRECAUTIONS
Turn ignition switch OFF and disconnect negative battery
cable before connecting or disconnecting the TCM harness
connector. Because battery voltage is applied to TCM even if
ignition switch is turned OFF.
When connecting or disconnecting pin connectors into or
from TCM, do not damage pin terminals (bend or break).
Check that there are not any bends or breaks on TCM pin ter-
minal, when connecting pin connectors.
Perform TCM input/output signal inspection and check
whether TCM functions normally or not before replacing TCM.
Refer to TM-275, "
Reference Value".
Perform “DTC Confirmation Procedure” after performing each
TROUBLE DIAGNOSIS.
If the repair is completed the DTC should not be displayed in
the “DTC Confirmation Procedure”.
 Always use the specified brand of CVT fluid. Refer to MA-11, "
Flu-
ids and Lubricants".
 Use lint-free paper, not cloth rags, during work.
 Dispose of the waste oil using the methods prescribed by law, ordi-
nance, etc. after replacing the CVT fluid.
Service Notice or PrecautionINFOID:0000000003806500
OBD SELF-DIAGNOSIS
 CVT self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the Malfunction Indicator (MI). Refer to the table on TM-204, "
CONSULT-III Function
(TRANSMISSION)" for the indicator used to display each self-diagnostic result.
 The self-diagnostic results indicated by the MI are automatically stored in both the ECM and TCM memories.
Always perform the procedure on TM-202, "
Diagnosis Description" to complete the repair and avoid
unnecessary blinking of the MIL.
For details of OBD, refer to EC-102, "
Diagnosis Description".
