Electric Shift Control Module

Component Description

FUNCTIONS WITHIN THE SYSTEM

The electric shift control module determines the shift position by the shift position information (ON/OFF signal) from the electric shift sensor and transmits the information to the VCM.

INDIVIDUAL FUNCTION WITHIN SYSTEM

The electric shift control module operates the parking actuator based on the range switching signal from VCM.

INDIVIDUAL OPERATION

The electric shift control module starts by power switch signal.

COMPONENT PARTS LOCATION

Electric shift control module is installed inside of center console.

Parking Actuator

Component Description

NOTE:

The parking actuator is composed of the motor, encoder, and actuator reduction gear.

FUNCTIONS WITHIN THE SYSTEM

The parking actuator is operated by the signal from the electric shift control module and locks/unlocks the parking mechanism in the reduction gear.

INDIVIDUAL FUNCTION WITHIN SYSTEM

Motor

The coil is arranged on the stator core of the outer circumferential side of motor and rotation power is generated in the inner circumference of the rotor core by sequentially applying current to the coil.

Encoder

• Detects the rotor rotation angle and outputs the pulse signal to the electric shift control module.

• The electric shift control module optimally controls the timing of the current that is supplied to the coil based on the signals from the encoder.

Actuator Reduction Gear

The actuator reduction gear consists of a cycloidal gear and includes a motor with its torque amplified for secure operation under high torque-requiring conditions.

INDIVIDUAL OPERATION

Locks or unlocks the parking mechanism in reduction gear of vehicle. Refer to Structure and Operation.

COMPONENT PARTS LOCATION

The parking actuator is installed on the upper part of the reduction gear.

Parking Actuator Relay

Component Description

FUNCTIONS WITHIN THE SYSTEM

Parking actuator relay is controlled by the electric shift control module and it connects/disconnects the motor coil circuit in the parking actuator.

INDIVIDUAL FUNCTION WITHIN SYSTEM

Parking actuator relay is turned ON by the electric shift control module when the power switch is switched ON and supplies power to motor coil located in the parking actuator.

INDIVIDUAL OPERATION

The normally open type is adopted for the parking actuator relay.

COMPONENT PARTS LOCATION

Parking actuator relay is installed inside the front bumper on the right side.

Electric Shift Selector

Component Description

FUNCTIONS WITHIN THE SYSTEM

When the selector lever and the P position switch are operated, sends a signal to the electric shift control module, and shifts to the requested shift position.

INDIVIDUAL FUNCTION WITHIN SYSTEM

Shift position		Operation/Function
H (Home position)		Returns to home position automatically after the selector lever was operated.	: Operate after pressing the select button : Operated without pressing the select button
P (P position switch)		Stop the Nissan Ariya vehicle completely and, with the brake pedal depressed, press the P position switch. Refer to Component Description.
R		With the brake pedal depressed, press the selector knob button and slide the selector lever 2 steps forward (toward the “R” indication) to shift to the R position.
N	Nr	When in the D or B position, with the brake pedal depressed, slide the selector lever 1 step forward and hold it there for approximately 1 second to shift to the N position. NOTE: When in the R position, even if the selector lever is moved forward (in the Nr direction), the shift position warning buzzer sounds, and the position does not shift to the N position.
	Nd	When in the R position, with the brake pedal depressed, slide the selector lever 1 step rearward and hold it there for approximately 1 second to shift to the N position. NOTE: When in the D or B position, even if the selector lever is moved rearward (In the Nd direction), the shift position warning buzzer sounds, and the position does not shift to the N position.
D or B		With the brake pedal depressed, slide the selector lever 2 steps rearward (toward the “D/B” indication) to shift to the D position. While driving in the D position, again slide the selector lever 2 steps rearward (toward the “D/B” indication) to change to the B position. To shift from the B position to the D position, again slide the selector lever 2 steps rearward (toward the “D/B” indication). For the B position functions, Refer to System Description.

*: Direct shifting to the B position from the P, R, and N position is not possible.

INDIVIDUAL OPERATION

When the selector lever is operated, sends a signal to the electric shift control module.

COMPONENT PARTS LOCATION

The electric shift selector is installed to the center console.

Electric Shift Sensor

Component Description

FUNCTIONS WITHIN THE SYSTEM

When the electric shift sensor sends signals, the electric shift control module determines the shift position from the combination of the ON/OFF signal.

INDIVIDUAL FUNCTION WITHIN SYSTEM

Electric shift sensor incorporates 8 contact-less sensors (Hall IC) and switches it ON/OFF according to the position of the selector lever sensors.

INDIVIDUAL OPERATION

The electric shift sensor transmits ON/OFF signals to the electric shift control module according to the position of the selector lever.

COMPONENT PARTS LOCATION

The electric shift sensor is installed inside the frame of the electric shift selector.

P Position Switch

Component Description

FUNCTIONS WITHIN THE SYSTEM

When selector lever at H position, press the P position switch to shift to the P position.

INDIVIDUAL FUNCTION WITHIN SYSTEM

The P position switch transmits the ON/OFF signals of the 2 contact switches to the electric shift control module.

INDIVIDUAL OPERATION

• It is possible to switch to the P position in one operation by pressing the P position switch during a Nissan Ariya vehicle stop.

• The P position switch can not perform P position cancellation.

COMPONENT PARTS LOCATION

The P position switch is installed on the electric shift selector.

Component Description

FUNCTIONS WITHIN THE SYSTEM

Displays the currently selected shift position.

INDIVIDUAL FUNCTION WITHIN SYSTEM

Informs the driver of the currently selected shift position.
