PRECAUTION

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000000956403

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity 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 whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.

WARNING:

• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS section.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

< BASIC INSPECTION >

1.GET INFORMATION FOR SYMPTOM

Get the detailed information from the customer about the symptom (the condition and the environment when the incident/malfunction occurred).

>> GO TO 2.

OPERATION PROCEDURE

1. Turn ignition switch ON.

2. Adjust seat position [sliding, reclining, lifting (rear)].

3. The steering and outside mirror is adjusted automatically.

NOTE:

• The seat synchronization function will not operate if seat adjusting value is more than limit value.

Item Limit value Seat sliding 76 [mm] Seat reclining 9.1 [degrees] Seat lifter (rear) 20 [mm]

• The seat synchronization function will not operate if the steering column or door mirror moves to the operating end while this function is operating. Perform memory function or drive the vehicle at vehicle speed of 7 km/h or more once to activate this function again.

OPERATION PROCEDURE

1. Turn ignition switch ON

2. Press desired memory switch for more than 0.5 second.

3. Driver seat, steering and door mirror will move to the memorized position.

OPERATION CONDITION

U1000 CAN COMM CIRCUIT

Description INFOID:0000000000960620

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Modern vehicle is equipped with many electronic control unit, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected 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 Signal Chart. Refer to LAN-28, "

B2128 UART COMMUNICATION LINE

Revision: October 2006

2007 G35 Sedan

< COMPONENT DIAGNOSIS >

B2128 UART COMMUNICATION LINE

Description INFOID:0000000000960643

Driver seat control unit performs UART communication with the automatic drive positioner control unit using 2 communication lines, TX and RX line. Driver seat control unit receives the operation signals of tilt & telescopic switch, door mirror remote control switch, set switch and memory switch and the position signals of tilt & telescopic sensor and door mirror sensor from the automatic drive positioner control unit and transmits the operation request signal.

DTC Logic INFOID:0000000000960644

DTC DETECTION LOGIC

DTC No. Trouble diagnosis name DTC detecting condition Possible cause

• UART communication line

The communication between driver seat control uni t

P2128 UART COMM

and auto drive positioner control unit is interrupted for a period of time.

DTC CONFIRMATION PROCEDURE

(UART communication line is open or shorted)

• Driver seat control unit

• Automatic drive positioner control unit

1.STEP 1

Turn ignition switch ON.

>> GO TO 2.

2.STEP 2

Operate tilt & telescopic switch for more than 2seconds.

>> GO TO 3.

3.PROCEDURE 3

Check “Self diagnostic result” with CONSULT-III. Is the DTC detected?

YES >> Perform diagnosis procedure. Refer to ADP-64, "Diagnosis Procedure". NO >> INSPECTION END

Diagnosis Procedure INFOID:0000000000960645

1.CHECK UART COMMUNICATION LINE CONTINUITY

1. Turn ignition switch OFF.

2. Disconnect driver seat control unit and automatic drive positioner control unit connector.

3. Check continuity between driver seat control unit harness connector and automatic drive positioner control unit harness connector.
