HIRAIN NAVISTAR RKE Lock Remote Owner's Manual

System Description
The RKE (Remote Keyless Entry) system block consists of four modules: POWER, MCU, SWITCHES, and RF module. When a switch is pressed, the MCU sends signals to the RF module which then transmits RF signals via the antenna.
Operational Principle
When a switch is pressed, the MCU generates a wake-up signal and sends enable and data signals to the RF module. The RF module then transmits RF signals through the antenna.

Function Description

Remote Keyless Entry Function: The RKE allows for remote locking and unlocking of the vehicle.

Panic Function: Pressing the panic switch triggers the receiver to send a corresponding message if the key is suitable for the car.
Warning Function: In low power conditions, the RKE includes low power information in the message and triggers relevant warning messages.

Definition
RKE: Remote Keyless Entry

System Description

RKE system block

Operational principle

AS the system block shows, the RKE contains four modules. They are POWER, MCU, SWITCHES and RF module.

When any switch is pressed, a wake up signal of MCU will be active. Then MCU module will send enable signal and data signal to the RF module. Once the RF module receives these signals, it will send RF signal by antenna.

Function Description

Remote keyless entry function

Lock function
The receiver receives the RF signal when the lock switch is pressed. If the key is suit for the car, the receiver will send a corresponding message to lock the car.
Unlock function
The receiver receives the RF signal when the unlock switch is pressed. If the key is suit for the car, the receiver will send a corresponding message to unlock the car.

Auxiliary function1
The receiver receives the RF signal when the AUX1 switch is pressed. If the key is suit for the car, the receiver will send a corresponding message.
Auxiliary function2
The receiver receives the RF signal when the AUX2 switch is pressed. If the key is suit for the car, the receiver will send a corresponding message.

Panic function
The receiver receives the RF signal when the panic switch is pressed. If the key is suit for the car, the receiver will send a corresponding message .

Warning function
On the low power condition, if the RKE is used, it will add the low power information in the message. And the receiver will send the relevant warning message.
