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”.

Diagnosis ProcedureINFOID:0000000005928929
1.CHECK INPUT SIGNALS
With CONSULT-III
1. Start engine.
2. Select “SELECTION FROM MENU” in “DATA MONI TOR” mode for “TRANSMISSION” with CONSULT-III.
3. Start vehicle and read out the value of “STM STEP”, “SMCOIL A”, “SMCOIL B”, “SMCOIL C”, and
“SMCOIL D”.
OK or NG
OK >> GO TO 4.
NG >> GO TO 2.
2.CHECK HARNESS BETWEEN TCM AND STEP MOTOR
1. Turn ignition switch OFF.
2. Disconnect CVT unit connector and TCM connector.
3. Check continuity between TCM connector terminals and CVT unit harness connector terminals.
4. If OK, check harness for short to ground and short to power.
5. If OK, check continuity between body ground and CVT assembly.
6. Reinstall any part removed.
OK or NG
OK >> GO TO 3.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
3.CHECK STEP MOTOR
Check step motor. Refer to CVT-132, "
Component Inspection" .
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4.CHECK DTC
Perform CVT-129, "
DTC Confirmation Procedure" .
OK or NG
OK >> INSPECTION END
NG >> GO TO 5.

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.
