2001 NISSAN ALMERA TINO wiring

Trouble Diagnoses Introduction=NLRS0043CAUTION:
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
+Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.
+Keep ground portion clean.
DIAGNOSIS FUNCTIONNLRS0043S01The SRS self-diagnosis results can be read by using“AIR BAG”warning lamp and/or CONSULT-II. The read-
ing of these results is accomplished using one of two modes—“User mode”and“Diagnosis mode”.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system
malfunction through the operation of the“AIR BAG”warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the“AIR BAG”warning lamp and CONSULT-II are as follows:
User mode Diagnosis mode Display type
“AIR BAG”warning lamp X X ON-OFF operation
CONSULT-II—X Monitoring
NOTE:
Seat belt pre-tensioner malfunction is indicated by“AIR BAG”warning lamp.
DIAGNOSIS MODE FOR CONSULT-IINLRS0043S02+“SELF-DIAG [CURRENT]”
A current Self-diagnosis result (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requiring
repairs.
+“SELF-DIAG [PAST]”
Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The stored
results are not erased until memory erasing is executed.
+“TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed
on the CONSULT-II screen.
+“ECU DISCRIMINATED NO.”
The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification num-
ber (refer to the table below). This number will be displayed on the CONSULT-II screen. When replacing
the diagnosis sensor unit, refer to the part number for the compatibility. After installation, replacement with
a correct unit can be checked by confirming this classification number on the CONSULT-II screen.
For NISSAN MODEL V10, the diagnosis sensor unit classification numbers are as follows:
MODEL ECU DISCRIMINATED NO.
Models with single air bag and seat belt pre-tensioner A910
Models with dual air bags and seat belt pre-tensioner A911
Models with dual air bags, side air bag and seat belt pre-tensioner A912

If no malfunction is detected on“SELF-DIAG [CURRENT]”but mal-
function is indicated by the“AIR BAG”warning lamp, go to DIAG-
NOSTIC PROCEDURE 4, page RS-51, to diagnose the following
situations:
+Self-diagnostic result“SELF-DIAG [PAST]”(previously stored
in the memory) might not be erased after repair.
+The SRS system malfunctions intermittently.

9. Compare diagnostic codes to“CONSULT-II Diagnostic Code
Chart”, page RS-47.
10. Touch“BACK”key of CONSULT-II until“SELECT SYSTEM”
appears in order to return to User mode from Diagnosis mode.
11. Turn ignition switch“OFF”, then turn off and disconnect
CONSULT-II, and disconnect both battery cables.
