2003 NISSAN ALMERA N16 door lock

Trouble Diagnoses=NJEL0486The Timer Control Unit includes software to help during development testing, manufacturing and service. It
allows the technician to put it into Diagnostic Mode. In this mode, all switch inputs can be tested for continu-
ity.
When the timer control unit is in Diagnostic Mode, the control unit tests the component and indicate the result
by the hazard lamp flashing.

Checks
Once in Diagnostic Mode, the following inputs can be tested.
USER ACTION TCU Reaction COMPONENT TESTED
Driver’s door opened from closed (all
other doors closed)Hazards flash once Driver’s door open signal
Passenger or rear door opened from
closed (all other doors closed)Hazard flash once Door open signal for opened door
Driver’s door locked from unlocked Hazard flash once Driver’s door unlocksensor signal
Passenger door locked from unlocked Hazard flash once Assist door unlock sensor signal
Hazard switch is pressed from off Hazard flash once Hazard switch signal
Turn signal switch is moved to left from
offHazard flash once Left turn signal

USER ACTION TCU Reaction COMPONENT TESTED
Lighting switch turned 1st position or 2nd
position from offHazard flash once Tail lamp signal
Key put in ignition from out Hazard flash once Key in detect signal
Door lock/unlock switch is pressed Hazard flash once Central door lock/unlock signal
*) Hazard may flash a second time because of Driver’s door status signal change. The min. delay time between flash actions is 100
ms.
In case the system does not operate as described above, check the concernedcircuit for open or short. After
completion, the Diagnostic Mode can be switched off by pressing the rear defogger switch or by turning the
ignition to “ON”. The hazard lamp will flash at 3 Hz for 3 seconds to confirm that Diagnostic Mode has been
switched off.

COMPONENT DESCRIPTIONNJHA0209Intake Door MotorNJHA0209S01The intake door motor is attached to the intake unit. It rotates so
that air is drawn from inlets set by the heater control panel. Motor
rotation is conveyed to a lever which activates the intake door.
DIAGNOSTIC PROCEDURE FOR INTAKE DOOR

Disposal of Air Bag Module and Seat Belt Pre-
tensioner
NJRS0022Before disposing of air bag module and seat belt pre-tensioner,
or vehicles equipped with such systems, deploy the systems.
If such systems have already been deployed due to an
accident, dispose of them as indicated in “DISPOSING OF AIR
BAG MODULE AND SEAT BELT PRE-TENSIONER” (RS-40).
When deploying the air bag module and seat belt pre-
tensioner, always use the Special Service Tool; Deployment
tool KV99106400.
When deploying the air bag module and seat belt pre-
tensioner, stand at least 5 m (16 ft) away from the deployment
component.
When deploying air bag module and seat belt pre-tensioner, a
fairly loud noise is made, followed by smoke being released.
The smoke is not poisonous, however, be careful not to inhale
smoke since it irritates the throat and can cause choking.
Always activate one air bag module at a time.
Due to heat, leave air bag module unattended for more than
30 minutes after deployment. Also leave seat belt pre-ten-
sioner unattended for move than 10 minutes after deployment.
Be sure to wear gloves when handling a deployed air bag
module and seat belt pre-tensioner.
Never apply water to the deployed air bag module and seat
belt pre-tensioner.
Wash your hands clean after finishing work.
Place the vehicle outdoors with an open space of at least 6 m
(20 ft) on all sides when deploying air bag module and seat belt
pre-tensioner while mounted in vehicle.
Use a voltmeter to make sure the vehicle battery is fully
charged.
Do not dispose of the air bag module and seat belt pre-ten-
sioner un-deployed.
SRS005-B
CHECKING DEPLOYMENT TOOLNJRS0022S01Connecting to BatteryNJRS0022S0101CAUTION:
The battery must show voltage of 9.6V or more.
Remove the battery from the vehicle and place it on dry wood
blocks approximately 5 m (16 ft) away from the vehicle.
Wait 3 minutes after the vehicle battery is disconnected before
proceeding.
Connect red clip of deployment tool to battery positive termi-
nal and black clip to negative terminal.
Make sure the polarity is correct. The right side lamp in the
tool, marked “deployment tool power”, should glow with a
green light. If the right side lamp glows red, reverse the con-
nections to the battery.
