DTC P1757 FRONT BRAKE SOLENOID VALVEPFP:31940
DescriptionNCS001NH
Front brake solenoid valve is controlled by the TCM in response to signals sent from the PNP switch, vehicle
speed sensor and accelerator pedal position sensor (throttle position sensor). Gears will then be shifted to the
optimum position.
CONSULT-II Reference ValueNCS001NI
On Board Diagnosis LogicNCS001NJ
This is an OBD-II self-diagnostic item.
Diagnostic trouble code “P1757 FR/B SOLENOID/CIRC” with CONSULT-II or 6th judgement flicker with-
out CONSULT-II is detected under the following conditions.
–When TCM detects an improper voltage drop when it tries to operate the solenoid valve.
–When TCM detects as irregular by comparing target value with monitor value.
Possible CauseNCS001NK
Harness or connectors
(Solenoid circuit is open or shorted.)
Front brake solenoid valve
DTC Confirmation ProcedureNCS001NL
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, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T”
with CONSULT-II.
3. Touch “START”.
4. Start engine.
5. Drive vehicle and maintain the following conditions for at least 5
consecutive seconds.
ACCELE POSI: 1.5/8 - 2.0/8
SLCT LVR POSI: “D” position
GEAR: “3”
“4” (FR/B ON/OFF)
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions required for this test.
6. If DTC is detected go to AT-152, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.

DTC P1759 FRONT BRAKE SOLENOID VALVE FUNCTIONPFP:31940
DescriptionNCS001NN
Front brake solenoid valve is controlled by the TCM in response to signals sent from the PNP switch, vehi-
cle speed sensor and accelerator pedal position sensor (throttle position sensor). Gears will then be
shifted to the optimum position.
This is not only caused by electrical malfunction (circuits open or shorted) but also by mechanical mal-
function such as control valve sticking, improper solenoid valve operation.
CONSULT-II Reference ValueNCS001NO
On Board Diagnosis LogicNCS001NP
This is an OBD-II self-diagnostic item.
Diagnostic trouble code “P1759 FR/B SOLENOID FNCT” with CONSULT-II or 6th judgement flicker with-
out CONSULT-II is detected under the following conditions.
–When TCM detects that actual gear ratio is irregular, and relation between gear position and condition of
ATF pressure switch 1 is irregular during depressing accelerator pedal. (Other than during shift change.)
–When TCM detects that relation between gear position and condition of ATF pressure switch 1 is irregular
during releasing accelerator pedal. (Other than during shift change.)
Possible CauseNCS001NQ
