P1762 DIRECT CLUTCH SOLENOID VALVE
P1762 DIRECT CLUTCH SOLENOID VALVE
Description
INFOID:0000000003130541
• The direct clutch solenoid valve is controlled by the TCM in response to signals transmitted from the PNP
switch, vehicle speed sensor and accelerator pedal position sensor (throttle position sensor). Gears will then
be shifted to the optimum position.
• The direct clutch solenoid valve controls the direct clutch control valve in response to a signal transmitted
from the TCM.

DTC CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC CONFIRMATION PROCEDURE” has been previously performed, always turn ignition switch
OFF. Then wait at least 10 seconds before performing the next test.
1.
CHECK DTC DETECTION
With CONSULT-III
1.
Start the engine.
2.
Select “Data Monitor” mode for “TRANSMISSION”.
3.

P1774 LOW COAST BRAKE SOLENOID VALVE FUNCTION
Description
INFOID:0000000003130550
• Low coast brake solenoid valve is turned ON or OFF by the TCM in response to signals transmitted from the
PNP switch, vehicle 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 malfunc-
tion such as control valve sticking, improper solenoid valve operation.

when it tries to operate
the solenoid valve.
• Condition of ATF pres-
sure switch 2 is differ-
ent from monitor
value, and relation be-
tween gear position
and actual gear ratio is
irregular.
• Harness or connectors

circuit is open or short-
ed.)
• Low coast brake sole-
noid valve
• ATF pressure switch 2
