CONFIGURATION (CAN GATEWAY)
DescriptionINFOID:0000000006220583
Vehicle specification needs to be written with CONSULT-II
I because it is not written after replacing CAN gate-
way.
Configuration has three functions as follows
CAUTION:
 When replacing CAN gateway, you must perfo rm “WRITE CONFIGURATION” with CONSULT-III.
 Complete the procedure of “WRITE CONFIGURATION” in order.
 If you set incorrect “WRITE CONF IGURATION”, incidents might occur.
 Configuration is different for each vehicle model. Confirm conf iguration of each vehicle model.
 Never perform “WRITE CONFIGURATION” except for new CAN gateway.
Work ProcedureINFOID:0000000006220584
1.WRITING MODE SELECTION
CONSULT-III Configuration
Select “CONFIGURATION” of CAN gateway.
When writing saved data>>GO TO 2.
When writing manually>>GO TO 3.
2.PERFORM “WRITE CONFIG URATION - CONFIG FILE”
CONSULT-III Configuration
Perform “WRITE CONFIGURATION - Config file”.
>> WORK END
3.PERFORM “WRITE CONFIGURATION - MANUAL SELECTION”
CONSULT-III Configuration
1. Select “WRITE CONFIGURATION - Manual selection”.
2. Select “SETTING”.
3. When “COMMAND FINISHED”, select “End”.
>> GO TO 4.
4.CHECK “SELF DIAGNOSTIC RESULT”
1. Erase all ECU self-diagnosis results using CONSULT-III.
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON and wait for 2 seconds or more.
4. Perform “All DTC Reading” using CONSULT-III.
5. Check that all ECU self-diagnosis results have no DTC of CAN communication. NOTE:
DTCs of CAN communication are as follows:
 U0101
 U0140
 U0164
 U1000
 U1001
 U1507
Function Description
READ CONFIGURATION  Reads the vehicle configuration of current CAN gateway.
 Saves the read vehicle configuration.
WRITE CONFIGURATION - Manual selection Writes the vehicle configuration with manual selection.
WRITE CONFIGURATION - Config file Writes the vehicle configuration with saved data.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000006220585
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communicati
on speed and excellent error detection ability. Modern
vehicle is equipped with many electroni c 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 two communication lines (CAN-H and CAN-L) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.

CAN COMMUNICATION SYSTEM : CAN Communica-
tion Signal Chart".

NOTE:
(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts i
f found
damaged or if the auto belt tensioner reading reaches the maximum limit.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, refer to FL section.
(4) First replacement interval is 105,000 miles (168,000 km) or 84 months. After first replacement, replace every 75,000 miles (120,000
km) or 60 months. Use only Genu ine NISSAN Long Life Antifreeze/Coo lant (blue) or equivalent with proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water will reduce the life
expectancy of the factory-fill coolant.
(5) Periodic maintenance is not required. However, if valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perfo rm
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and inter vals are
required.

On Board Diagnosis FunctionINFOID:0000000006221719
ON BOARD DIAGNOSIS ITEM
The combination meter allows the following diagnosis items with the on-board diagnosis function.
METHOD OF STARTING
1. Turn ignition switch OFF.
2. While pressing the trip reset switch (1), turn ignition switch ON.
3. If the diagnosis function is activated with “trip A” displayed, the
mileage on “trip A” is reset to “0000.0”. (The same way for “trip
B”.)
4. Make sure that the trip meter displays “0000.0”.
5. Press the trip reset switch at least 3 times. (Wit hin 7 seconds after the ignition switch is turned ON.)
6. The combination meter is turned to self-diagnosis mode.  Speedometer, tachometer, engine coolant temper ature gauge, fuel gauge, engine oil pressure gauge,
and voltmeter return to zero, simultaneously.
 The dot matrix dots on the information display (1) blink alter-
nately.
NOTE:
 Check combination meter power supply and ground circuit when the self-diagnosis mode of the combi- nation meter does not start. Replace combination meter if power supply and ground circuit are normal.
 If any of the dots are not displayed, replace combination meter.

SPECIAL FUNCTION
Special menu
W/L ON HISTORY
 Stores histories when warning/indicator lamp is turned on.
 “W/L ON HISTORY” indicates the “TIME” when the warning/ indicator lamp is turned on.
 The “TIME” above is:
- 0: The condition that the warning/indicator lamp has been turned on 1 or more times after starting the engine and waiting for 30 seconds.
- 1 - 39: The number of times the engine was restarted after the 0 condition.
- NO W/L ON HISTORY: Stores NO (0) turning on history of warning/indicator lamp.
NOTE:
 W/L ON HISTORY is not stored for approximately 30 seconds after the engine starts.
 Brake warning lamp does not store any history when the parking brake is applied or the brake fluid level gets
low.

munication.
TOW MODE IND
[On/Off] Status of TOW mode indicator lamp judged from TOW mode indicator lamp signal
received from TCM with CAN communication line.
BUZZER

received from each unit via CAN communication and the warning output condition
of the combination meter.
