Integrated Gateway & Power control Module (IGPM)

Integrated Gateway & Power control Module (IGPM) is a module that performs the function of conventional Junction Block and some functions of BCM.

It controls various components including lamps by using CAN communication and IPS (replacing the function of fuse and relay) or ARISU.

IPS stands for Intelligent Power Switch, which uses the semiconductor technology to replace the current role of fuse and relay. (The IPS chip has two functions: 1) the high current-based component control; 2) component protection from overcurrent.)

The advantages of IPS are as follows:

–	Reduce relay and consequently decrease weight and volume

–	Remove the relay operation noise

–	No need to replace fuses and increase the product life

–	Capable to diagnose faulty parts

IGPM protection

(1)

PCL (Programmable Current Limit) functions

–	PCL replaces the junction block function of protecting wires.

–	How to operate : If the lamp current exceeds the standard level, cut off the current to protect the lamp.

–	Lamp cut off time : 300ms or less.

–	Applied components: all lamp components controlled by IGPM

–	Output the error code according to the error detection conditions.

(2)

OCL (Open Current Limit)

–	OCL detects the lamp open state and informs the user of it.

–	How to operate: Detect the current of the lamp and if it is below the standard level, change the lamp operation.

–	Applied components: 4 turn signal lamps.

–	Output the error code according to the error detection conditions.

IGPM fail safe function

(1)	When the MCU is out of order (not operating due to a physical or electrical shock from the outside), and IGN2 and head lamp low switch are on, IGPM forces the head lamp low and exterior/interior lamps to turn on in order to secure the driver’s safety.

(2)

When the data transmission/reception fails due to a failed CAN communication line connected with IGPM module (disconnection of both high and low line, high/low BAT short, high/low GND short), the head lamp low and interior/exterior tail lamps are forced to turn on if IGN2 is on and the head lamp low switch is on.

Auto Cut System of Dark Current

(1)	Description : It cuts automatically power to be provided with components for reducing useless dark current according to vehicle state.

(2)

IGPM had 3 modes, "Normal Mode", "Sleep Mode", "Power Off Mode". Auto cut of dark current practice in "Sleep Mode".

–	- “Sleep” condition: IG OFF, consistent state of the input switch during a certain time, non-operation state of the CAN network.

–	- “Sleep” deactivation condition: switch inputs, operation state of the CAN network, KEY ON, POWER ON.

–	- “Power off” condition: In the dark current automatic cutoff function, the timer set for cutting the power load runs out.

–	"Normal Mode" : IGPM function normally activates.

–	"Sleep Mode" : It is low power mode and activates for reducing electricity consumption of IGPM. Auto cut of dark current function activates.

–	"Power OFF Mode" : Power of MCU and circumferential circuit is cut for minimizing electricity consumption. Operation stops.

(3)

The explanation - The auto cut of dark current

Before delivering to customer

Fuse switch OFF

•	All door close & RKE door lock or Consistent switch state (Auto cut of dark current scenario starts.)

–	5 minutes after entering the “sleep” state.

–	IGPM power down(IGPM dark current : 200 μA) and cutting power of Lamp /Body Load/Wake up/Immobilzer

After delivering to customer

Fuse switch ON

•	All door close & Constant switch state : Burglar Alarm State=OFF (Auto cut of dark current scenario starts.)

–	After "sleep" state is for 20 min.

–	IGPM power down(IGPM dark current : 200 μA) and cutting power of Lamp Load

•	In case RKE door lock : Burglar Alarm State=ON & Tailgate Switch=CLOSE (Auto cut of dark current scenario starts.)

–	After "Sleep" state 35s~65s (Waiting time of other unit : 30~60s + IGPM sleep counts 5 min)

–	IGPM Powerdown(IGPM dark current : 200 μA) and cutting power of Lamp Load

Possible problems in case of the fuse switch setting errors

: If a fuse switch is set to OFF(Before delivering to customer) by a customer or technician and auto cut function of dark current activates, the following problems may occur.

Symptom

Related part

•	Door lock/unlock, tailgate open don't activate by RKE. (Wakeup of each module don't activate.)

BCM

•	Digital clock is reset.(Memory is reset.)

Digital clock

•	Audio setting values (volume, frequency setting) are reset. (Memory is reset.)

Audio

* If fuse switch OFF(before delivering to customer) is set, power of BCM, Digital clock and audio is shut off.
