DTC P1757 FRONT BRAKE SOLENOID VALVEPFP:31940
DescriptionECS00G02
Front brake solenoid valve is controlled by TCM in response to signals sent from PNP switch, vehicle speed
sensor and accelerator pedal position sensor. Gears will then be shifted to the optimum position.
CONSULT-II Reference ValueECS00G03
On Board Diagnosis LogicECS00G04
Diagnostic trouble code “P1757 FR/B SOLENOID/CIRC” with CONSULT-II or 6th judgement flicker without
CONSULT-II is detected under the following conditions.
lWhen TCM detects an improper voltage drop when it tries to operate the solenoid valve.
lWhen TCM detects as irregular by comparing target value with monitor value.
Possible CauseECS00G05
lHarness or connectors
(The solenoid circuit is open or shorted.)
lFront brake solenoid valve
DTC Confirmation ProcedureECS00G06
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 toAT- 1 3 8 , "
Diagnostic Procedure".
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle and maintain the following conditions for at least 5 consecutive seconds.
Accelerator opening: 1.5/8 - 2.0/8
Selector lever position: “D” position
Gear position: “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.
