Diagnostic trouble code “P1757 FR/B SO LENOID/CIRC” with CONSULT-III or 6th judgement flicker without
CONSULT-III 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 CauseINFOID:0000000001327274

DTC Confirmation ProcedureINFOID:0000000001327275
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, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON.
2. Select “SELECTION FROM MENU” in “DATA MONI TOR” mode for “TRANSMISSION” with CONSULT-III
and check monitor “ACCELE POSI”, “SLCT LVR POSI” and “GEAR”.
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 vehic le uphill (increased engine load) will help maintain the driving
conditions required for this test.
6. If DTC is detected go to AT-145, "
Diagnosis Procedure".
