DTC P0773 Shift Solenoid E Electrical Malfunction
(Shift Solenoid Valve SL)
CIRCUIT DESCRIPTION
The shift solenoid valve SL is turned ON and OFF by signals from the ECM to control the hydraulic pressure
acting on the lock±up relay valve, which then controls operation of the lock±up clutch.
Fail safe function
If the ECM detects a malfunction, it turns the shift solenoid valve SL OFF.

Either (a) or (b) is detected for 1 time.(2 trip detection logic)
(a) Solenoid resistance is 8 W or less short circuit when sole-
noid is energized.
(b) Solenoid resistance is 100 kW or more open circuit when
solenoid is not energized.

DTC P1520 Stop Light Switch Signal Malfunction
CIRCUIT DESCRIPTION
The purpose of this circuit is to prevent the engine from stalling, while driving in lock±up condition, when
brakes are suddenly applied.
When the brake pedal is depressed, this switch sends a signal to ECM. Then the ECM cancels operation
of the lock±up clutch while braking is in progress.
DTC No.DTC Detecting ConditionTrouble Area
P1520No stop light switch signal to ECM during driving.

O/D Cancel Signal Circuit
CIRCUIT DESCRIPTION
While driving uphill with cruise control activated, in order to minimize gear shifting and provide smooth cruis-
ing overdrive may be prohibited temporarily under some conditions.
The cruise control ECU sends O/D cut signals to the ECM as necessary and the ECM cancels overdrive
shifting until these signals are discontinued.

CIRCUIT DESCRIPTION
The O/D main switch contacts go open when the switch is pushed in and go closed when it is pushed out.
In O/D main switch in OFF position, the O/D OFF indicator light lights up, and the ECM prohibits shifting over-
drive.

DTC P0500 Vehicle Speed Sensor Malfunction
CIRCUIT DESCRIPTION
The vehicle speed sensor outputs a 4±pulse signal for every revolution of the rotor shaft, which is rotated
by the transmission output shaft via the driven gear. After this signal is converted into a more precise rectan-
gular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the
ECM. The ECM determines the vehicle speed based on the frequency of these pulse signals.
