P1777 STEP MOTOR
DescriptionINFOID:0000000005928923
• The step motor is included in the control valve assembly.
• The step motor changes the step with turning 4 coils ON/OF F according to the signal from TCM. As a result,
the flow of line pressure to primary pu lley is changed and pulley ratio is controlled
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000005928924
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000005928925
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P1777” with CONSULT-III is detected under the following conditions.
- When operating step motor ON and OFF, there is no proper change in the voltage of TCM terminal which
corresponds to it.
Possible CauseINFOID:0000000005928926
• Step motor
• Harness or connectors(Step motor circuit is open or shorted.)
DTC Confirmation ProcedureINFOID:0000000005928927
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, 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. Drive vehicle for at least 5 consecutive seconds.
3. If DTC is detected, go to CVT-131, "
Diagnosis Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III”.

• The brake fluid level is low
Trouble DiagnosisINFOID:0000000005929168
HOW TO PERFORM TROUBLE DIAGNOSIS
1. Confirm the symptom or customer complaint.
2. Perform preliminary check. Refer to "PRELIMINARY CHECK" .
3. According to the symptom chart, repair or replace the cause of the malfunction. Refer to DI-15, "
Symptom
Chart" .
4. Does the meter operate normally? If so, GO TO 5. If not, GO TO 2.
5. Inspection End.
PRELIMINARY CHECK
1.CHECK SELF-DIAGNOSIS OPERAT ION OF COMBINATION METER
Perform self-diagnosis of combination meter. Refer to DI-11, "
Self-Diagnosis Mode of Combination Meter" .

The knock sensor retard system is designed only for emergencies. The basic ignition timing is programmed
within the anti-knocking zone, if recommended fuel is
used under dry conditions. The retard system does not
operate under normal driving conditions. If engine knocking occurs, the knock sensor monitors the condition.
The signal is transmitted to the ECM. The ECM retards the ignition timing to eliminate the knocking condition.
