• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecti ng both battery cables with the ignition knob in the
″ LOCK ″ position.
• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS , an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.

DIAGNOSTIC PROCEDURE 6
Inspect SRS Malfunction Using "AIR BAG" Warning Lamp—Diagnosis Mode
NOTE:
SRS will not enter Diagnosis mode if no malfunction is detected in User mode.
1. Turn ignition switch ON.
2. After “AIR BAG” warning lamp lights for 7 seconds, turn ignition switch OFF within 1 second.
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 two more times (3 times total).
5. Turn ignition switch ON.
SRS is now in Diagnosis mode. Refer to SRC-85, "
Trouble Diagnosis without CONSULT-III".
CONSULT-III Function (AIR BAG)INFOID:0000000001735301
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
Self-Diagnosis Function (Without CONSULT-III)INFOID:0000000001735302
• The reading of these results is accomplished using one of two modes — “User mode” and “Diagnosis
mode”.
• After a malfunction is repaired, turn the ignition s witch OFF for at least one second, then back ON. Diagnosis
mode returns to the User mode. At that time, the self-diagnostic result is cleared.
AIR BAG diagnostic mode Description
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-III screen in real
time. This refers to a malfunctioning part requir-
ing repairs.
SELF-DIAG [PAST] Diagnosis results previously stored in the memo
ry are displayed on the CONSULT-III screen. The
stored results will remain until memory erasing is executed.
TROUBLE DIAG RECORD With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-III screen.
ECU DISCRIMINATED NO. Air bag diagnosis sensor unit ECU discriminated number (identification number) is displayed. Air bag
diagnosis sensor unit has individual ECU discriminated number (identification number) based on model
and equipment.
PASSENGER AIR BAG The STATUS (readiness) of the front passenger air bag module is displayed. The STATUS displayed
(ON/OFF) depends on the signals supplied to the occupant classification system control module and
air bag diagnosis sensor unit. Refer to
SRC-10, "
Occupant Classification System (OCS)" for more in-
formation.
