Precautions for Battery ServiceNKS0054E
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

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 3 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 power mode.

CAN communication is stopped.

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

When a change in hood switch or ignition switch signal is detected, mode switches to CAN communica-
tion status.
CAN Communication System DescriptionNKS000E5
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 UnitNKS000E6
Refer to LAN-48, "CAN System Specification Chart" .
Function of Detecting Ignition Relay MalfunctionNKS000E7

When contact point of integrated ignition relay is stuck and cannot be turned OFF, IPDM E/R turns ON
parking lamp, license plate lamp and tail lamp for 10 minutes to indicate ignition relay 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, tail lamp relay and daytime light relay are OFF.

NOTE:

Perform monitoring of IPDM E/R data with the ignition switch ON. When the ignition switch is at ACC, the display may not be cor-
rect.

*2: The vehicle without intelligent key system displays only ON without change.

*3: Only the vehicle with daytime light system operates.
