REMOTE KEYLESS ENTRY SYSTEM

System Description

INPUTS
Power is supplied at all times
- to BCM terminal 7
- through 50 A fusible link (letter f, located in the fuse and fusible link box).
- to key switch terminal 3
- through 10 A fuse [No. 19, located in the fuse block (J/B)].

When the key switch is ON (ignition key is inserted in key cylinder), power is supplied
- through key switch terminal 4
- to BCM terminal 62.

When the front door switch LH is ON (door is OPEN), ground is supplied
- to BCM terminal 14 and 54 (without vehicle security system).
- through front door switch LH terminal 2
- to driver door switch case ground.

When the front door switch RH is ON (door is OPEN), ground is supplied
- to BCM terminal 10
- through front door switch RH terminal 2
- to front door switch RH case ground.

When the rear door switches are ON (door is OPEN), ground is supplied
- to BCM terminal 11
- through rear door switches terminal 1
- to rear door switches case grounds.

Key fob signal is inputted to smart entrance control unit (the antenna of the system is combined with BCM).

The remote keyless entry system controls operation of the
- power door lock
- trunk lid opener
- interior lamp and step lamps
- panic alarm
- hazard and horn reminder
- keyless power window down (open)

OPERATED PROCEDURE

Power Door Lock Operation
BCM receives a LOCK signal from key fob. BCM locks all doors with input of LOCK signal from key fob.
When an UNLOCK signal is sent from key fob once, driver's door will be unlocked.

Then, if an UNLOCK signal is sent from key fob again within 5 seconds, all other door will be unlocked.

Hazard and Horn Reminder
BCM output to IPDM E/R for hazard and horn reminder signal as DATA LINE (CAN H line and CAN L line).
The hazard and horn reminder has C mode (horn chirp mode) and S mode (non-horn chirp mode).




Operating function of hazard and horn reminder.

How to change hazard and horn reminder mode

With CONSULT-II
Hazard and horn reminder can be changed using "WORK SUPPORT" mode in "MULTI ANSWER BACK SET".




Without CONSULT-II
When LOCK and UNLOCK signals are sent from the key fob for more than 2 seconds at the same time, the hazard and horn reminder mode is changed and hazard warning lamp flashes and horn sounds as follows:

Interior Lamp Operation
When the following input signals are both supplied:
- door switch CLOSED (when all the doors are closed);
- driver's door LOCKED;

Remote keyless entry system turns on interior lamp and ignition illumination (for 30 seconds) with input of UNLOCK signal from key fob.

For detailed description, refer to "INTERIOR LAMP TIMER OPERATION".

Panic Alarm Operation
When key switch is OFF (when ignition key is not inserted in key cylinder), remote keyless entry system turns on and off horn and headlamp intermittently with input of PANIC ALARM signal from key fob.

The alarm automatically turns off after 25 seconds or when BCM receives any signal from key fob. For detailed description, refer to "VEHICLE SECURITY (THEFT WARNING) SYSTEM".

Trunk Lid Opener Operation
When a TRUNK OPEN signal is sent with key OFF (ignition key removed from key cylinder) from key fob, power is supplied
- through BCM terminal 19
- to trunk lid opener actuator terminal 3.

When power and ground are supplied, trunk lid opener actuator opens trunk lid.

Keyless Power Window Down (open) Operation
When key fob unlock switch is turned ON with ignition switch OFF, and the switch is detected to be on continuously for 3 seconds, the driver's door and passenger's door (with left and right front power window anti-pinch system) power windows are simultaneously opened.

Power window is operated to open and the operation continues as long as the key fob unlock switch is pressed.

CAN Communication System Description
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
