2. Check voltage between Intelligent Key unit connector and ground.
OK or NG
OK >> Check the condition of harness and connector. If it is
OK, check the self-diagnosis results using CONSULT-II
again.
NG >> Check the following.
10A fuse [No.22, located in the fuse block (J/B)]
Harness for open or short between fuse block and
Intelligent Key unit.
DTC B2563 HI VOLTAGENIS001YZ

the voltage is 18V or more is detected for 90 seconds or more, it judges that it is the malfunction and displays
the DTC (Diagnostic Trouble Code)
TERMINAL AND REFERENCE VALUE FOR INTELLIGENT KEY UNIT
Standard is the measured voltage between each terminal and ground

VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: 2006 January2006 M35/M45
System DescriptionNIS001ZU
DESCRIPTION
Operation Flow
Setting the Vehicle Security System
Initial condition
Ignition switch is in OFF position.
Disarmed phase
When hood, doors or trunk is open, the vehicle security system is set in the disarmed phase on the
assumption that the owner is inside or near the vehicle.
When the vehicle security system is in the disarmed phase, the security indicator lamp blinks every 2.4
seconds.
Pre-armed phase and armed phase
When the following operation 1 or 2 is performed, the vehicle security system turns into the “pre-armed”
phase. (The security indicator lamp illuminates.)
1. BCM receives LOCK signal from front door key cylinder switch or Intelligent Key, after hood, trunk and all
doors are closed.
2. Hood, trunk and 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
When one of the following operations is performed, the armed phase is canceled.
1. Unlock the doors with the key or Intelligent Key.
2. Turn ignition switch “ON” or “ACC” position.
Canceling the Alarm Operation of the Vehicle Security System
When unlock the door with the key or Intelligent Key the alarm operation is canceled.
Activating the Alarm Operation of the Vehicle Security System
Make sure the system is in the armed phase. (The security indicator lamp brinks every 2.4 seconds.)
When the following operation 1 or 2 is performed, the system sounds the horns and flashes the headlamps for
about 50 seconds.
1. Hood, trunk or any door is opened during armed phase.
2. Disconnecting and connecting the battery connector before canceling armed phase.
