DIAGNOSIS MODE FOR CONSULT-II=NJRS0043S02+ªSELF-DIAG [CURRENT]º
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.
+ªSELF-DIAG [PAST]º
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.
+ªTROUBLE DIAG RECORDº
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed
on the CONSULT-II screen.
+ªECU DISCRIMINATED NO.º
The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification num-
ber. This number will be displayed on the CONSULT-II screen, as shown below. When replacing the diag-
nosis sensor unit, refer to the part number for the compatibility. After installation, replacement with a cor-
rect unit can be checked by confirming this classification number on the CONSULT-II screen.
For NISSAN MODEL N16, the diagnosis sensor unit classification numbers are as follows:

+Align spiral cable correctly when installing steering wheel.
a) Set the front wheels in the straight-ahead position.
b) Make sure that the spiral cable is in the neutral position.
The neutral position is detected by turning left 2.5 revolutions
from the right end position. Align the two marks (
).
CAUTION:
The spiral cable may snap due to steering operation if the
cable is installed in an improper position.
Also, with the steering linkage disconnected, the cable may
snap by turning the steering wheel beyond the limited number
of turns. (The spiral cable can be turned up to 2.5 turns from
the neutral position to both the right and left.)
