U1010 CONTROL UNIT (CAN)
DescriptionINFOID:0000000006256085
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 malfunction detection ability.
Many electronic control units are equipped onto a vehi cle, and each control unit shares information and links
with other control units during operation (not independently ). 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/recei ves data but selectively reads required data only.

INFOID:0000000006226152
A/T Shift Selector (Detention Switch)INFOID:0000000006226153
Detention switch detects that A/T sh ift selector is in the P position, and then transmits the signal to BCM and
IPDM E/R.
BCM confirms the A/T shift selector position with the following 5 signals.
 P position signal from A/T shift selector (detention switch)
 P/N position signal from TCM
 P position signal from IPDM E/R (CAN)
 P/N position signal from IPDM E/R (CAN)
 P/N position signal from TCM (CAN)
IPDM E/R confirms the A/T shift select or position with the following 3 signals.
 P position signal from A/T shift selector (detention switch)
 P/N position signal from TCM
 P/N position signal from BCM (CAN)
BCMINFOID:0000000006226154
BCM controls INTELLIGENT KEY SYSTEM (ENGIN E START FUNCTION), INFINITI VEHICLE IMMOBI-
LIZER SYSTEM-NATS [IVIS (NATS)], and VEHICLE SECURITY SYSTEM.
BCM performs the ID verification between BCM and Intelligent Key when the Intelligent Key is carried into the
detection area of inside key antenna, and push-button ignition s witch is pressed. If the ID verification result is
OK, push-button ignition switch operation is available.

COMPONENT PARTS
Push-button Ignition Switch
INFOID:0000000006226165
Push-button ignition switch detects that push-button is pressed, and then transmits the signal to BCM. BCM
changes the power supply position with the operation of push-button ignition switch. BCM maintains the power
supply position status while push-button is not operated.
Remote Keyless Entry ReceiverINFOID:0000000006226166
Remote keyless entry receiver receives each button oper ation signal and electronic key ID signal from Intelli-
gent Key, and then transmits the signal to BCM.
Security Indicator LampINFOID:0000000006226167
Security indicator lamp is located on combination meter.
Security indicator lamp blinks when power supply position is any position other than ON to warn that INFINITI
VEHICLE IMMOBILIZER SYSTEM-N ATS [IVIS (NATS)] is on board.
Starter Control RelayINFOID:0000000006226170
Engine starting system functions by controlling both starter relay and starter control relay.
Both relays are integrated in IPDM E/R. Starter relay is controlled by BCM, and starter control relay is con-
trolled by IPDM E/R on request from BCM.
IPDM E/R transmits starter relay and starter control relay status signal to BCM via CAN communication.
Starter RelayINFOID:0000000006226171
Engine starting system functions by controlling both starter relay and starter control relay.
Both relays are integrated in IPDM E/R. Starter relay is controlled by BCM, and starter control relay is con-
trolled by IPDM E/R on request from BCM.
IPDM E/R transmits starter relay and starter control relay status signal to BCM via CAN communication.
Steering Lock RelayINFOID:0000000006226172
Steering lock relay is integrated in IPDM E/R, and supplies power source to steering lock unit.
When IPDM E/R receives the steering lock relay ON request signal from BCM, IPDM E/R turns ON steering
lock relay and then transmits the steering lock relay condition signal to BCM.
Steering Lock UnitINFOID:0000000006226173
Steering lock unit performs steering lock/unlock operation on request from BCM, and power source is supplied
from steering lock relay integrated in IPDM E/R.
When push-button ignition switch is pressed while the In telligent Key is inside the vehicle, BCM performs the
ID verification with steering lock unit. Steering lock unit releases the steering lock based on the result of the ID
verification.
Steering lock unit has 2 switches (steering lock status switch and steering unlock status switch) inside. BCM
judges the steering lock/unlock condition by comparing these switch signals and steering lock unit status sig-
nal transmitted from IPDM E/R via CAN communication.
Stop Lamp SwitchINFOID:0000000006226174
Stop lamp switch detects that brake pedal is depressed, and then transmits the signal to BCM.
Transmission Range SwitchINFOID:0000000006226175
Transmission range switch is integrated in A/T asse mbly, and detects the A/T shift selector position.
TCM receives the transmission range switch signal and then transmits the P/N position signal to BCM and
IPDM E/R.
BCM confirms the A/T shift selector position with the following 5 signals.
 P position signal from A/T shift selector (detention switch)
 P/N position signal from TCM
 P position signal from IPDM E/R (CAN)
 P/N position signal from IPDM E/R (CAN)
 P/N position signal from TCM (CAN)
IPDM E/R confirms the A/T shift select or position with the following 3 signals.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint S
ystem (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006226734
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, which could increase the risk of personal injury or death in
the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISS AN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the “SRS AIR BAG”.
 Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
 When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s)
with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly
causing serious injury.
 When using air or electric power tools or hammers , always switch the ignition OFF, disconnect the
battery, and wait at least 3 minu tes before performing any service.
General PrecautionsINFOID:0000000006226735
Turn ignition switch OFF an d disconnect the battery cable
from the negative terminal before connecting or disconnect-
ing the A/T assembly connector. Because battery voltage is
applied to TCM even if igniti on switch is turned OFF.
 Perform “DTC (Diagnostic Trouble Code) CONFIRMATION
PROCEDURE” after performing each TROUBLE DIAGNOSIS.
If the repair is completed DTC should not be displayed in the
“DTC CONFIRMATION PROCEDURE”.
 Always use the specified brand of ATF. Refer to MA-10, "
Fluids
and Lubricants".
 Use lint-free paper not cloth rags during work.
 Dispose of the waste oil using the methods prescribed by law, ordi-
nance, etc. after replacing the ATF.
 Before proceeding with disassembly, thoroughly clean the outside of the transmission. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
