Nissan Leaf. Manual — part 1156
TM-30
< PRECAUTION >
[ELECTRIC SHIFT]
PRECAUTIONS
If the battery is removed within 5 minutes after the power switch is turned OFF, plural DTCs may be
detected.
4. Remove 12V battery terminal within 60 minutes after turning the power switch OFF
→ ON → OFF.
CAUTION:
• After all doors (including back door) are closed, if a door (including back door) is opened before
battery terminals are disconnected, start over from Step 1.
• After turning the power switch OFF, if “Remote A/C” is activated by user operation, stop the air
conditioner and start over from Step 1.
NOTE:
Once the power switch is turned ON
→ OFF, the 12V battery automatic charge control does not start for
approximately 1 hour.
• For vehicles with the 2-batteries, be sure to connect the main battery and the sub battery before turning ON
the power switch.
NOTE:
If the power switch is turned ON with any one of the terminals of main battery and sub battery disconnected,
then DTC may be detected.
• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.
NOTE:
The removal of 12V battery may cause a DTC detection error.
General Precautions
INFOID:0000000010119540
• Never turn the power switch ON while the selector lever is in the D or R position. Otherwise, the vehicle may
start abruptly resulting in an accident.
• Never shift the selector lever to the R position while the vehicle is moving forward, or to the D position while
moving backward, or press the P position switch while the vehicle is in motion. Otherwise, excessive force
may be applied to the drive system causing damage.
• Never allow the vehicle to coast backward while the selector lever is in the D position or forward while the
selector lever is in the R position.
• Part A shown in the figure contains a strong magnet. Persons with
an electro-medical apparatus should keep away from this area.
Otherwise, the magnet may cause the electro-medical apparatus
to malfunction.
• Keep magnetic objects, such as magnetic cards, and metal prod-
ucts (e.g. watches) away from the area surrounding the magnet.

SYSTEM DESCRIPTION
DESCRIPTION
Description
INFOID:0000000010119541
• Instead of the conventional mechanical shift mechanism, the electric shift system is adopted which electri-
cally detects shifting operation and locks/unlocks the parking mechanism by operating the parking actuator.
• The electric shift control module is build into the VCM.
NOTE:
In this section, the electric shift control module built in VCM is referred to as “Electric shift control module” for
describing its functions.
• The momentary-type selector lever is adopted for mouse-like fine shift operability.
• The automatic P position function, which automatically shifts the gear to the P position if the power switch is
turned OFF in the each position, is adopted.
• For improved functionality and operability, the P position switch, which allows direct switching to the P posi-
tion at the touch of the switch, is provided on the top of the selector lever.

Electric Shift Control Module
INFOID:0000000010119543
• The electric shift control module is build into the VCM.
NOTE:
In this section, the electric shift control module built in VCM is referred to as “Electric shift control module” for
describing its functions.
• The electric shift control module is started by the power switch signal and wake-up signal transmitted from
BCM.
• The electric shift control module determines the shift position based on the shift position data (ON/OFF sig-
nal) from the electric shift sensor, and transmits the shift position data to VCM and traction motor inverter via
EV system CAN.
• The electric shift control module operates the parking actuator based on the signal from the P position
switch.
Parking Actuator
INFOID:0000000010119544
• The parking actuator is installed above the reduction gear.
• The parking actuator is operated by the signal from the electric
shift control module and locks/unlocks the parking mechanism in
the reducer.
• The parking actuator consists of the motor, encoder, and actuator
reduction gear.
MOTOR
• A 3-phase SR motor is used.
• Coil is placed on the stator core around the motor and the current
that passes through the coil in sequence generates the rotating
force for the inner rotor core.
ENCODER
• The Hall IC type rotation angle sensor is used for higher accuracy in the detection of the rotor rotation angle.
• It detects the rotor rotation angle and outputs pulse signals to the electric shift control module.
• The electric shift control module controls the timing of the current feed to the coils optimally based on the
signal 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.
