Before installing the balance weight, be sure to clean the
mating surface of the road wheel.
Indicated unbalance value × 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz) = 40 g (1.41 oz) balance
weight (closer to calculated balance weight value)
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4 = 35 g (1.23 oz)
37.5 = 40 g (1.41 oz)
a. Install balance weight in the position shown in the figure at right.
b. When installing balance weight to road wheels, set it into the
grooved area on the inner wall of the road wheel as shown in the
figure so that the balance weight center is aligned with the wheel
balancer indication position (angle).
CAUTION:

Always use genuine Nissan adhesion balance weights.

Balance weights are unreusable; always replace with new
ones.

Do not install more than three sheets of balance weight.
c. If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other (as shown in
the figure).
CAUTION:
Do not install one balance weight sheet on top of another.
3. Start wheel balancer again.
4. Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start wheel balancer. Make sure that inner and outer residual
unbalance values are 7.5 g (0.26 oz) each or below.

If either residual unbalance value exceeds 7.5 g (0.26 oz), repeat installation procedures.

IPDM E/R STATUS CONTROL
In order to save power, IPDM E/R switches status by itself based on each operating condition.
1. CAN communication status

CAN communication is normally performed with other control units.

Individual unit control by IPDM E/R is normally performed.

When sleep request signal is received from BCM, mode is switched to sleep waiting status.
2. Sleep waiting status

Process to stop CAN communication is activated.

All systems controlled by IPDM E/R are stopped. When 1 seconds have elapsed after CAN communi-
cation with other control units is stopped, mode switches to sleep status.
3. Sleep status

IPDM E/R operates in low current-consumption mode.

CAN communication is stopped.

When a change in CAN communication line is detected, mode switches to CAN communication status.

When a change hood switch or ignition switch signal is detected, mode switches to CAN communica-
tion status.
CAN Communication System DescriptionAKS005SA
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicles are equipped with many electronic control units and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitAKS00AOF
Refer to LAN-6, "CAN Communication Unit" .
Function of Detecting Ignition Relay MalfunctionAKS005SB

When contact point of integrated ignition relay is stuck and cannot be turned OFF, IPDM E/R turns ON tail
and parking lamps for 10 minutes to indicate IPDM E/R malfunction.

When a state of ignition relay having built-in does not agree with a state of Ignition switch signal input by a
CAN communication from BCM, IPDM E/R lets tail lamp relay operate.
NOTE:
When the ignition switch is turned ON, the tail lamp is OFF.
