INTRODUCTION
Nissan is conducting this voluntary service campaign on certain specific model year 20112019 LEAF vehicles to replace the Lithium-Ion battery bonding plates. This service will be
performed at no charge to the customer for parts or labor.
IDENTIFICATION NUMBER
Nissan has assigned identification number P9312 to this campaign. This number must
appear on all communication and documentation of any nature dealing with this campaign.
DEALER RESPONSIBILITY
Dealers are to repair vehicles falling within range of this campaign that enter the service
department. This includes vehicles purchased from private parties, vehicles presented by
transient (tourists) owners, and vehicles in a dealer’s inventory.

Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

SERVICE PROCEDURE
IMPORTANT: Follow all warnings, cautions, and notes in the Electronic Service
Manual (ESM) when working on or near the High Voltage System.


Refer to the ESM for all warnings, cautions, and notes: GENERAL INFORMATION
> GENERAL INFORMATION > PRECAUTION > CAUTIONS AS TO HIGH
VOLTAGE/HIGH VOLTAGE PRECAUTIONS.

NOTE: This procedure is to be performed ONLY by a technician with current LEAF
certification.
1.

Disconnect the high voltage system.


Refer to the ESM for disconnecting the high voltage system: GENERAL
INFORMATION > GENERAL INFORMATION > PRECAUTION > CAUTIONS AS
TO HIGH VOLTAGE > HOW TO DISCONNECT HIGH VOLTAGE > PROCEDURE
FOR DISCONNECTING HIGH VOLTAGE.

2.

Place the vehicle on a lift.

3.

Remove the Li-Ion battery under cover (front).


Refer to the ESM for Li-Ion battery under cover (front) removal: BODY EXTERIOR,
DOORS, ROOF & VEHICLE SECURITY > EXTERIOR > REMOVAL AND
INSTALLATION > LI-ION BATTERY UNDER COVER (FRONT).



See Figure 1 for 2011-2017 models and Figure 2 for 2018-2019 models.

4.

Perform potential equalization
inspection.
a. Remove the harness clamp (A) (see
Figure 3).
b. Disconnect the Li-Ion battery high
voltage harness connector (B) (see
Figure 4).

Figure 3

Figure 4

c. Using the insulation resistance tester, check the voltage between both terminals of
the HV harness.
 If the reading is 5 volts or less, continue to step 5.
 If the reading is over 5 volts, wait 10 minutes and retest. Do not continue to step
5 until the reading is 5 volts or less.

10.

Perform an electric equipotential test.
For 2011-2012 LEAF, measure the
resistance between the two (2) battery
pack ground bolts and the body
ground (not pictured).
For 2013-2019 LEAF, measure the
resistance between the body of the
battery pack and the vehicle body.
See Figure 7.
 If the resistance is less than 0.1
ohm, continue to step 11.

Figure 7

 If the resistance is 0.1 ohm or greater, check and correct the following:


Conditions of the bonding plate connection.



Corrosion on the bonding plate mounting surface.



Presence of paint, oil, dirt, or other substance on the bonding plate mounting
surface.

11.

Reconnect the Li-Ion battery high voltage harness connector.

12.

Reinstall the harness clamp.

13.

Reinstall the Li-Ion battery under cover (front).


Refer to the ESM for Li-Ion battery under cover (front) installation: BODY
EXTERIOR, DOORS, ROOF & VEHICLE SECURITY > EXTERIOR > REMOVAL
AND INSTALLATION > LI-ION BATTERY UNDER COVER (FRONT).

14.

Lower the vehicle.

15.

Connect the high voltage system.


Refer to the ESM for connecting the high voltage system: GENERAL
INFORMATION > GENERAL INFORMATION > PRECAUTION > CAUTIONS AS
TO HIGH VOLTAGE > HOW TO DISCONNECT HIGH VOLTAGE >
PROCEDURE FOR CONNECTING HIGH VOLTAGE.
