DTC P1762 DIRECT CLUTCH SOLENOID VALVE
DescriptionINFOID:0000000001327283
Direct clutch solenoid valve is controlled by the TCM in response to signals sent from the PNP switch, vehicle
speed sensor and accelerator pedal positi on sensor (throttle position sensor). Gears will then be shifted to the
optimum position.
CONSULT-III Reference Val ue in Data Monitor ModeINFOID:0000000001327284
On Board Diagnosis LogicINFOID:0000000001327285
Diagnostic trouble code “P1762 D/C SOLENOID/CIRC” with CONSULT-III or 2nd 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:0000000001327286
 Harness or connectors
(Solenoid circuit is open or shorted.)
 Direct clutch solenoid valve
DTC Confirmation ProcedureINFOID:0000000001327287
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: “1” ⇒ “2” (D/C 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-147, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
Diagnosis ProcedureINFOID:0000000001327288

6. Remove snap ring from A/T assembly harness connector.
7. Push A/T assembly harness connector.CAUTION:
Be careful not to damage connector.
8. Remove bracket (1) (VK45DE), clips (2), oil pan (3) and oil pan gasket.
 : Vehicle front
 : Bolt (22)
 Drain plug (4)
9. Check foreign materials in oil pan to help determine causes of malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.
 If frictional material is de tected, perform A/T fluid cooler
cleaning. Refer to AT-13, "
A/T Fluid Cooler Cleaning".
10. Remove magnets from oil pan.

8. Check foreign materials in oil pan to help determine causes of malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can c ause valves, servo, and clutches
to stick and can inhibit pump pressure.
 If frictional material is detected, perform A/T fluid cooler
cleaning. Refer to AT-13, "

9. Support A/T assembly with a transmission jack. CAUTION:
When setting transmission jack, place wooden blocks to
prevent from damaging control valve with TCM and trans-
mission case.
