DTC P1777 STEP MOTOR - CIRCUIT
Description INFOID:0000000004667069
• 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 Val ue in Data Monitor Mode INFOID:0000000004667070
Remarks: Specification data are reference values.
On Board Diagnosis Logic INFOID:0000000004667071
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P1777 STEP MOTR CIRC” with CONSULT-III is detected under the following con-
ditions.
- When operating step motor ON and OFF, there is no proper change in the voltage of TCM terminal which corresponds to it.
Possible Cause INFOID:0000000004667072
• Step motor
• Harness or connectors
(Step motor circuit is open or shorted.)
DTC Confirmation Procedure INFOID:0000000004667073
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, alw ays turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESU LTS” 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-143, " Diagnosis Procedure " .
