start from step 2 if you are not using
the hand±held tester.
1READ VALUE OF MASTER CYLINDER PRESSURE SENSOR
(a)Select the DATALIST mode on the hand±held tester.
(b)Check that the brake fluid pressure value of the No.1 master cylinder pressur\
e sensor and No.2 master
cylinder pressure sensor displayed on the hand±held tester changes wh\
en depressing the brake ped-
al.
OK:
Brake fluid pressure value is changing.

DTC P0717/37 TURBINE SPEED SENSOR CIRCUIT NO
SIGNAL
CIRCUIT DESCRIPTION
This sensor detects the rotation speed of the input turbine. By comparing the input turbine speed signal (NT)
with the counter gear speed sensor signal (NC), the ECM detects the shift timing of the gears and appropri-
ately controls the engine torque and hydraulic pressure according to various conditions. Thus smooth gear
shifting is performed.
DTC No.DTC Detection ConditionTrouble Area
P0717/37
ECM detects conditions (a), (b), (c) and (d) continuity for 5 sec.
or more: (2 trip detection logic)
(a) Vehicle speed: 50 km/h (20 mph) or more
(b) 2nd, 3rd or O/D gear
