«Norma» SUEP functions

Lock door locks and enable security mode with the remote control

To lock the door locks and turn on the security mode, press the lock button on the remote control, Fig. 4.

The side door locks and the tailgate lock (trunk lid) (in the variant version) will be locked, and the security mode will be activated at the same time, which is confirmed by a single flashing of the direction indicators and a slow flashing of the immobilizer indicator in the instrument cluster.

If any door or hood is opened when the security mode is activated, the direction indicators will flash three times and a single sound signal will be emitted.

To include open zones in the security zone, close them.

The system will behave similarly if the door lock overheating protection is triggered, if the locks are locked / unlocked repeatedly within a short period of time.

In this case, wait a while, after which the system will be fully operational again.

Lock the locks without turning on the security mode with Remote control

To lock the lock in doors with a remote control without turning on the security mode, press the lock button twice or hold it down for a while. In this case, the doors will be locked without turning on the security mode.

This locking is accompanied by three-time blinking of the direction indicators.

If the security mode is already on, then double-pressing the lock button or holding it down will turn off the security mode, while the door locks will remain locked.

Turning off the security mode is accompanied by two-time blinking of the direction indicators.

Unlocking the door locks and turning off the security mode using the remote control

To unlock the driver's door lock and turn off the security mode using the remote control, press the unlock button.

The driver's door lock will be unlocked, and turning off the security mode is accompanied by a two-time blinking of the direction indicators.

To unlock the passenger door locks, press the unlock button on the remote control again.

If after unlocking the doors and turning off the security mode there is no none of the doors are open and the ignition is not turned on, then after 25 seconds the doors will be locked again and the system will automatically switch to the security mode.

The automatic transition of the system to the security mode with the doors locked is accompanied by frequent flashing of the immobilizer indicator in the instrument cluster.

Attention! If the security mode does not turn off with the remote control due to a drop in battery voltage in the remote control, it is possible to open the door with the key. This will trigger the alarm, which can be turned off by turning on the ignition.

The car will be used without the possibility of turning on the alarm.

Central locking and unlocking of door locks from the passenger compartment

To lock all doors from the passenger compartment, press the lock button in the driver's door.

To unlock the driver's door, lift the lock button in the driver's door.

To unlock all doors from the passenger compartment, press the unlock button on the remote control.

The central lock has door lock overheating protection.

If the locks are locked and unlocked repeatedly within a short period of time, the system stops responding to button presses.

If this happens, do not press the button for a while, after which the system will fully recover.

To to ensure security, the last command executed is always the unlock command.

Central door locking from outside the vehicle

To lock all doors from outside the vehicle, turn the key in the driver's door lock counterclockwise.

Turning the key clockwise does not centrally unlock all doors; only the door that is currently being opened is unlocked.

System operation in security mode.

After the security mode is turned on, the system monitors the status of the following security zones:

• - side doors;
• - hood;
• - tailgate;
• - ignition switch;
• - driver's door lock;
• - battery voltage;
• - additional sensor (not included in the factory package).

If in the security mode, any of the following actions occur:

• - opening any side door;
• - opening the hood;
• - opening the tailgate;
• - turning on the ignition without using "your" key;
• - unlocking the driver's door;
• - connecting the battery after disconnecting it;
• - then the alarm is turned on in the form of light signaling with turn indicators and an audible signal with the standard sound signal of the car for about 30 seconds.

A single press of any button on the remote control when the system is in the alarm mode leads to the cessation of alarm signals, but the system remains in the security mode.

The security mode is turned off after pressing the unlock button on the remote control.

Resynchronization of codes Remote control

If the remote control buttons are pressed outside the radio channel coverage area, the counter of the "floating" code in the remote control goes out of synchronization with the counter in the system control unit.

If the number of remote control button presses outside the system signal reception area exceeds 1000, the system will stop responding to remote control commands.

In this case, the immobilizer training procedure should be repeated.

Replacing a faulty electrical package control unit

If the electrical package control unit is faulty, after replacing it, perform the immobilizer training procedure with "your" training key.

If a fault occurs in the system, the corresponding fault code is entered into the memory of the electrical package control unit.

The list of fault codes for the SDUEP is given in the table
