NOTE:
Nissan Armada 2wd v8 5.6L Parts Service 119
The Intelligent Key door lock/unlock functions are controlled by several components. Proper diagnostic steps should be performed before replacing
any part. The BCM (Body Control Module) is usually not the cause of an inoperative condition.
DIAGNOSTIC ITEMS
NOTE:
When testing door lock/unlock with Intelligent Key:
^ Set the ignition switch position to OFF or LOCK.
^ Put the shift lever in Park.
^ Intelligent key is not inserted into key slot (if equipped).
^ All doors are closed.
^ Intelligent key is outside the vehicle and 6 feet or less from the request switch.
^ As needed, refer to Figure 2 above.
Check operation of the door locks with the power door lock switch.
^ If a door will lock/unlock with the power door lock switch on the inside door panel, then the actuator is OK and the wiring between the
actuator and BCM is OK.
^ If needed, refer to the appropriate Service Manual to diagnose and repair the power door lock system.
Check signals from the Intelligent Key and the vehicle antenna using Signal Tech II.
^ Follow the Signal Tech II instruction manual for Intelligent Key testing.
Nissan Armada 2wd v8 5.6L Parts Service 120
^ The Signal Tech II instruction manual is found in ASIST under Tools & Equipment.
Correct any no-signal or low-signal conditions:
^ If there is no-signal or low-signal from the Intelligent Key, inspect the Intelligent Key and its battery.
> Refer to NTB08-107 for intelligent key inspection.
> Refer to the appropriate Service Manual for battery test procedure.
> Intelligent Key battery voltage must be above 2.8 volts.
> If the battery voltage is OK, replace the Intelligent Key.
^ If there is no-signal or low-signal from the outside door handle antenna, check the antenna.
> Refer to the appropriate Service Manual for antenna diagnostic and repair procedure.
Confirm the BCM is receiving door lock/unlock signals
^ Use C-III or C-III plus > Intelligent Key > Data Monitor.
^ REQ SW-DR/AS will change OFF > ON as Door Request Switch is pressed.
^ RKE - LOCK/UNLOCK will change OFF > ON as the buttons on the Intelligent Key (keyfob) are pressed.
NG - Repair as needed. Refer to the appropriate Service Manual
NOTE:
The Remote Keyless Entry Receiver must confirm the NATS / Intelligent Key is registered before the doors will lock/unlock with Request Switch or
the Intelligent Key (keyfob) buttons.
Confirm NATS / Intelligent Key registration
^ Refer to the appropriate Service Manual and C-III / C-III plus Operators Manual for NATS / Intelligent Key registration confirmation.

P0151
P0131, P0151 A/F SENSOR 1
Component Description
The air fuel ratio (A/F) sensor 1 is a planar one-cell limit current sensor. The sensor element of the A/F sensor 1 is composed an electrode layer,
which transports ions. It has a heater in the element.
The sensor is capable of precise measurement lambda = 1, but also in the lean and rich range. Together with its control electronics, the sensor
outputs a clear, continuous signal throughout a wide lambda range.
The exhaust gas components diffuse through the diffusion layer at the sensor cell. An electrode layer is applied voltage, and this current relative
oxygen density in lean. Also this current relative hydrocarbon density in rich.
Therefore, the A/F sensor 1 is able to indicate air fuel ratio by this electrode layer of current. In addition, a heater is integrated in the sensor to
ensure the required operating temperature of about 800癈 (1,472癋).
On Board Diagnosis Logic
To judge the malfunction, the diagnosis checks that the A/F signal computed by ECM from the A/F sensor 1 signal is not inordinately low.

On Board Diagnosis Logic
To judge the malfunction of A/F sensor 1, this diagnosis measures response time of the A/F signal computed by ECM from the A/F sensor 1
signal. The time is compensated by engine operating (speed and load), fuel feedback control constant, and the A/F sensor 1 temperature index.
Judgment is based on whether the compensated time (the A/F signal cycling time index) is inordinately long or not.

Description
The active brake booster consists of a vacuum booster, an active booster control group and a delta stroke sensor. If a brake booster system
malfunction occurs due to loss of vacuum, the delta stroke sensor will signal the ABS actuator and electric unit (control unit) that a booster
malfunction has occurred. The active booster then applies supplemental force to the master cylinder relative to the amount of force exerted on the
brake pedal.
