3. CAN DIAG SUPPORT MNTR (without PAST): Check the CAN DIAG SUPPORT MNTR (without PAST) of
units indicating “U1000” or “U1001” on SELF-DIAG RESULTS. Draw a line on the diagnosis sheet to indi-
cate the possible error circuit.
NOTE:
While an error occurred in the past according to SELF-DIAG RESULTS, it is unclear which signal is not
received. Assume that errors were detected from all reception items.
Draw a single line among the unit and all reception items. (Work flow differs from CAN DIAG SUPPORT
MNTR (with PAST).)
a. Reception item of “EPS”: Assume that the unit could not receive the signals from ECM, ABS, and M&A.
Draw a line among EPS, ECM, ABS, and M&A (line 3-a in the figure).
b. Reception item of “ABS”: Assume that the unit could not receive the signal from ECM. Draw a line
between ABS and ECM (line 3-b in the figure).

4. Search for the possible cause using CAN communication signal chart using information from the interview
with the customer.
NOTE:
For the details of CAN communication signal, refer to LAN-48, "
CAN Communication Signal Chart" .
a. ABS warning lamp turned ON and speedometer did not move: This means that “ABS warning lamp signal”
and “Vehicle speed signal” could not communicate between M&A and ABS (4-a in the figure).
b. The tachometer moved normally: This means that “Engine speed signal” could communicate normally
between ECM and M&A (4-b in the figure).

5. Fill out the diagnosis sheet based on information from step 4.
a. The ABS warning lamp turned ON and speedometer did not move: Assume that a possible cause is no
communication between M&A and ABS. Draw a line between M&A and ABS. (Line 5-a in the figure).
b. The tachometer moved normally: Put check marks between ECM and M&A. The circuit between ECM and
M&A is functioning properly (check marks 5-b in the figure).

Past Error — Short Circuit —
When the symptoms listed below exist, a short circuit of the CAN communication line is a possible cause.
Item (CONSULT-II) Indication Inspection procedure
SELF-DIAG RESULTS “U1000” and “U1001” is indicated in the past for most units.
Refer to LAN-71, "

CAN DIAG SUPPORT MNTROnly on CAN DIAG SUPPORT MNTR (with PAST), “1 - 39” is
indicated on “PAST” of “TRANSMIT DIAG” and the reception
item.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
UKS005VK
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 Man-
ual.
WAR NIN G:
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 per-
formed by an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal 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.
Precautions When Using CONSULT-IIUKS005YD
Use CONSULT-II CONVERTER when connecting CONSULT-II to data link connector.
CAUTION:
CAN communication does not function properly if CONSULT-II is used without connecting CONSULT-II
CONVERTER.
Precautions for Trouble DiagnosisUKS005YE
CAUTION:
Never apply 7.0 V or more to the measurement terminal.
Use a tester with open terminal voltage of 7.0 V or less.
Turn the ignition switch OFF and disconnect the battery cable from the negative terminal when
checking the harness.
Precautions for Harness RepairUKS005YF
Solder the repaired area and wrap tape around the soldered
area.
NOTE:
A fray of twisted lines must be within 110 mm (4.33 in).
