DTC P1715 Rear Wheel Sensor Circuit Malfunction
(Rear Speed Sensor)
CIRCUIT DESCRIPTION
The rear speed sensor detects the rear wheel speed based on
revolution of the transfer drive gear.
Its construction is the same as that of the front speed sensor
(See page DI−206).
The center differential clutch is controlled by the ECM based on
the signals from the front speed sensor and rear speed sensor
signals.

DTC P1760 Linear Solenoid for Line Pressure Control
Circuit Malfunction (Shift Solenoid Valve ST)
CIRCUIT DESCRIPTION
When the difference in speed between the front wheels and rear wheels is large, and this takes place during
an extreme low−speed operation in the D, 2, or L position, shift solenoid valve ST is turned ON by the signal
from the ECM.

DIAGNOSTIC TROUBLE CODE CHART
If a malfunction code is displayed during the DTC check, check the circuit listed for that code. For details
of each code, turn to the page referred to under the ”See page” for the respective ”DTC No.” in the DTC chart.
HINT:
Using SST 09843−18020, connect the terminals Tc and E1, and remove the short pin.
If any abnormality is not found when inspect each inspection parts, inspect the ECU.
