Auto Door Lock Function
When all doors are locked, ignition knob switch is OFF (when ignition switch is not pressed) and key switch is
OFF (when mechanical key is out of ignition key cylinder), doors are unlocked with Intelligent Key button.
When Intelligent Key unit does not receive the following signals within 30 seconds, all doors are locked.

Door switch is ON (door is opened)

Door is locked

Ignition knob switch is ON (ignition switch is pressed)

Key switch is ON (mechanical key is inserted in ignition switch)
Auto door lock mode can be changed by “AUTO RELOCK TIMER” mode in “WORK SUPPORT”. Refer to BL-
11 3 , "WORK SUPPORT" .
Panic Alarm Function
When ignition knob switch is OFF (ignition switch is not pressed), or key switch is OFF (mechanical key is not
inserted in key cylinder), by press and holding the panic alarm button on Intelligent Key will send a panic alarm
signal to Intelligent Key unit.
Intelligent Key unit sends alarm request signal to BCM via CAN communication line.
BCM sends headlamp request signal and horn signal to IPDM E/R. Then, IPDM E/R turns on and off head-
lamp and horn intermittently.
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off:

After 25 seconds

When Intelligent Key unit receives any signal from remote controller of Intelligent Key

When door request switch is pressed (Intelligent Key is outside vehicle)
Panic alarm function's press and holding time value can be changed in “PANIC ALARM DELAY” mode in
“WORK SUPPORT”. Refer to BL-113, "

VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: June 20062007 Versa
System DescriptionEIS009AY
DESCRIPTION
Operation Flow

Setting the vehicle security system
Initial condition

Ignition switch is in OFF position.
Disarmed phase

When the vehicle is being driven or when any door is open, the vehicle security system is set in the dis-
armed phase on the assumption that the owner is inside or near the vehicle.
Pre-armed phase and armed phase

The vehicle security system turns into the "pre-armed" phase (security lamp illuminates) when the BCM
receives LOCK signal from front door key cylinder switch, keyfob or Intelligent Key after all doors are
closed.

All doors are closed after front doors are locked by key or door lock and unlock switch.
The security indicator lamp illuminates for 30 seconds. then, the system automatically shifts into the "armed"
phase.
Canceling the set vehicle security system
The armed phase is canceled when the driver unlocks the doors with the key, keyfob or Intelligent Key.
Activating the alarm operation of the vehicle security system
Make sure the system is in the armed phase.
When one of the following operations is performed, the system sounds the horns and flashes the headlamps
for about 50 seconds.
1. Any door is opened before unlocking door with key, keyfob or Intelligent Key.
2. Door is unlocked without using key, keyfob or Intelligent Key.
POWER SUPPLY AND GROUND
Power is supplied at all times

through 10A fuse [No.13, located in the fuse block (J/B)]

to combination meter terminal 27 (security indicator lamp)

through 40A fusible link (letter g , located in the fuse and fusible link box)

to BCM terminal 70

through 10A fuse [No. 8, located in the fuse block (J/B)]

to horn relay terminal 2

through 15A fuse (No. 52, located in the IPDM E/R)

to IPDM E/R internal CPU.

through 20A fuse (No. 53, located in the IPDM E/R)

to IPDM E/R internal CPU.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 20, located in the fuse block (J/B)]

to BCM terminal 11.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 6, located in the fuse block (J/B)]

to BCM terminal 38.
Ground is supplied

to BCM terminal 67

through body grounds M57 and M61.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors.
To activate the vehicle security system, BCM must receive signals indicating the ignition switch is OFF, doors
are closed and locked.
When a door is open, BCM terminal 12, 13, 43, 47 or 48 receives a ground signal from each door switch. In
addition to BCM, when back door is open, the Intelligent Key unit terminal 23 receives a ground signal from
back door through BCM terminal 30.
When front door LH is unlocked, BCM terminal 46 receives a signal from terminal 6 of main power window and
door lock/unlock switch.
When front door RH is unlocked, BCM terminal 46 receives a signal from terminal 2 of power window and door
lock/unlock switch RH.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by

opening a door

unlocking door without using the key, keyfob or Intelligent Key.
The vehicle security system will be triggered once the system is in armed phase,

when BCM receives a ground signal at terminals 12, 13, 47, 48 (front or rear door switch), or terminal 43
(back door switch).
When the vehicle security system is triggered, ground is supplied intermittently

from IPDM E/R terminal 45

to horn relay terminal 1.
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 50 seconds, but will reactivate if the vehicle is tampered with again.
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door must be unlocked with the key, keyfob or Intelligent Key.
When the key is used to unlock the driver door, BCM terminal 7 receives signal

from terminal 3 of the front door key cylinder switch LH.
When the BCM receives this signal or unlock signal from keyfob or Intelligent Key or front door key cylinder
switch LH, the vehicle security system is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
Intelligent Key and remote keyless entry system may or may not operate vehicle security system (horn and
headlamps) as required.
When the remote keyless entry system is triggered, ground is supplied intermittently

from IPDM E/R terminal 45

to horn relay terminal 1.
The headlamp flashes and the horn sounds intermittently.

TROUBLE DIAGNOSES FOR SYMPTOMS
Revision: June 20062007 Versa
Long Stopping DistanceEFS006LY
1. CHECK BASE BRAKING SYSTEM PERFORMANCE
1. Disable ABS by disconnecting ABS actuator and electric unit (control unit) connector.
2. Drive vehicle and check brake operation.
NOTE:

Stopping distance may be longer than vehicles without ABS when road condition is slippery.

Driving the vehicle with the ABS actuator and electric unit (control unit) disconnected may induce DTCs
in electrical control units using CAN communication. After the inspection, clear all DTCs. Refer to LAN-
4, "SYSTEM DESCRIPTION" .
OK or NG
OK >> Go to BRC-30, "ABS Works Frequently" .
NG >> Perform Basic Inspection. Refer to BRC-17, "
Basic Inspection" .
ABS Does Not WorkEFS006LZ
CAUTION:
The ABS does not operate when the vehicle speed is 10 km/h (6 MPH) or less.
1. CHECK WARNING LAMP ACTIVATION
Turn ignition switch ON and check for warning lamp activation.

Warning lamp should activate for approximately 2 seconds after turning the ignition switch ON.
OK or NG
OK >> Carry out self-diagnosis. Refer to BRC-20, "SELF-DIAGNOSIS" .
NG >> Go to BRC-17, "
ABS WARNING LAMP INSPECTION" .
Pedal Vibration or ABS Operation NoiseEFS006M0
NOTE:
During ABS activation, pedal vibration may be felt and a noise may be heard. This is normal and does not indi-
cate a malfunction.
1. CHECK SYMPTOM
1. Apply brake.
2. Start engine.
Does the symptom occur only when engine is started?
YES >> Carry out self-diagnosis. Refer to BRC-20, "SELF-DIAGNOSIS" .
NO >> GO TO 2.
2. RECHECK SYMPTOM
Does the symptom occur only when electrical equipment switches (such as headlamps) are turned on?
YES >> Check for radio, antenna or related wiring that is routed too close to the ABS actuator and electric
unit (control unit) and reroute as necessary.
NO >> Go to BRC-30, "
ABS Works Frequently" .
