Remote control system for the electric package of a Chevrolet Niva car

On cars of configurations 55 and 34, the Norma power package remote control system (SDUEP) is installed

SDUEP "Norma" is intended for:

• - remote locking / unlocking of door locks with simultaneous switching on / off of the car security mode;
• - lock all doors by turning the key in the driver's door lock;
• - lock / unlock all doors with a button on the driver's door;
• - turn on an alarm in case of violation of the car's security zones;
• - turn off the alarm remotely or after turning on the ignition with your key.

SDUEP "Norma" consists of an electrical package control unit and a remote control (RC)

Scheme of connections SDUEP "Norma" is shown in fig. 3.

Addresses of the output plugs of the power package control unit "Norma":

Plug number - Address (plug destination)

• 3 - ECM, terminal "71", (W-line)
• 4 - Driver's door lock sensor
• 5 - Rear window heating element
• 6 - Body
• 8 - Instrument cluster, immobilizer indicator
• 9 - Hood switch
• 10 - Rear passenger door sensors

For the remote control to work as part of the SDUEP, it must be trained using the learning key from the immobilizer (see "Learning the immobilizer").

After learning, the remote control is also a working key of the immobilizer and serves to remove the prohibition of starting the engine.

Functions of the "Norma" EMS

Locking door locks and arming from the remote control

 

To lock the door locks and activate the armed mode, press the lock button on the remote control, fig. 4.

At the same time, the locks of the side doors and the lock of the tailgate (trunk lid) (in the variant version) will be blocked, and the armed mode will be activated at the same time, which is confirmed by a single flash of the direction indicators and a slow flash of the immobilizer signaling device in the instrument cluster.

If any door or hood is opened when arming, the direction indicators will flash three times and a single beep will sound.

To include open zones in the guard zone, close them. A similar behavior of the system will be in case of overheating protection of the door locks, if the locking / unlocking of the locks occurs repeatedly within a short period of time.

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

Lock locks without arming with remote control.

To lock the door locks with remote control without arming, press the lock button twice or hold it down for a while. In this case, the doors will be blocked without arming.

Such blocking is accompanied by three flashes of direction indicators.

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

Disarming is accompanied by double flashing of direction indicators.

Unlocking door locks and disarming from the remote control

Press the unlock button to unlock the driver's door and disarm from the remote control. The driver's door lock is unlocked, and disarming is accompanied by a double flashing of the direction indicators.

Press the unlock button on the remote again to unlock the passenger doors.

If, after unlocking the doors and turning off the security mode, none of the doors is opened 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 armed mode.

Automatic transition of the system to armed mode with door locking is accompanied by frequent flashing of the immobilizer indicator in the instrument cluster.

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

Further operation of the car will be carried out without the possibility of turning on the alarm.

Central locking and unlocking of the doors from the passenger compartment

To lock all doors from inside the car, push the lock button into the driver's door.

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

Press the unlock button on the remote control to unlock all the doors from inside the car.

The central locking has protection of the door locks against overheating. If locking and unlocking occurs 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. For security purposes, the last command executed is always the unlock command.

Central locking of door locks from outside the car

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

When the key is turned clockwise, the central unlocking of all doors does not occur, only the door that is currently opening is unlocked.

The system is armed.

After arming, the system monitors the status of the following armed zones:

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

If any of the following occurs while armed:

• - opening any side door;
• - hood opening;
• - opening the tailgate;
• - turn on the ignition without using "your" key;
• - unlocking the driver's door;
• - connecting the battery after disconnecting it;

- then an alarm is activated in the form of a light signal with direction indicators and an audible signal with a regular sound signal of the car for about 30 seconds.

A single press of any button on the remote control when the system is in alarm mode will stop the alarms, but the system will remain armed.

Disarming occurs after pressing the unlock button on the remote control.

Resynchronization of remote control codes

If you press the buttons of the remote control outside the coverage area of the radio channel, 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 signal reception area of the system exceeds 1000, the system will stop responding to remote control commands. In this case, the immobilizer training procedure should be repeated.

Replacing a faulty electric package control unit

In the event of a malfunction of the power package control unit, after replacing it, carry out the immobilizer training procedure with your “own” learning key.

In the event of a malfunction in the system, the corresponding malfunction code is entered in the memory of the power package control unit. The list of SDUEP fault codes is given in the table
