Cluster Variant Coding

As we have more options (ESC, MDPS, SCC, etc.) in the car, the dashboard now have more information to display depending on the chosen options.

For this reason, we need to learn which options the current vehicle when we replace the dashboard.

To address this issue, a course of learning based on the option required for the vehicle when replacing the dashboard should be carried out.

This is called Variant Coding.

Function

High speed CAN communication (C-CAN)

–	Custom Function : Boarding interlocking sheets, Welcome Light

–	LDWS : Lane Departure Warning System

–	SPAS: Smart Parking Assist System

Low speed CAN communication (MM-CAN)

–	AV : Audio / Video Multimedia information Display

–	TBT : Turn By Turn Navigation Information Display

3.	Sound output Instrument cluster and the external speakers connected to the output of the various beeps and sound effects. If External AMP is applied, the directional alarm is outputted through the amp.

User Setting Mode (USM)

Setting can be changed by using switchs (Menu, UP, Down and OK button). There are many items (for example, In/Out Seat Synchronization, In/Out Steering Wheel Synchronization, Auto Door Lock, Auto Door Lock Deactivate, Head Lamp Escort, Welcome Light, Welcome Sound, One Touch Turn Signal, Average Fuel Consumption Auto Reset, Brightness, and Content Setup) that can be set and customized. The signal flow during setting is as follows.

(1)	UMS settings are set, they are transmitted to BCM.

(2)	BCM transmits the settings via B_CAN to the relevant modules.

(3)	The module completes setting and transmits the modified setting to BCM.

(4)

BCM transmits the final settings via C_CAN to the cluster.

•	The cluster communicates directly with C-CAN units.

Hybrid Mian Features

ECO and power guage

(1)	It displays the degree of economic driving by identifying the status of a driver's operation, depending on a vehicle's driving conditions (e.g., required power, system efficiency and

(2)	It leads to economic driving by informing the driver of the optimal driving conditions depending on the vehicle's conditions.

(3)	It displays that ECO guide and power segment will operate during driving, and also indicates the state of regenerative braking when a charge zone is instructed while driving.

SOC(State of Charge) guage

(1)	It displays the amount of charge of high-voltage battery.

(2)	It displays the charged amount of SOC received from BMS module on the digital gauge in the instrument cluster (as follows).

No	SOC(%)	No	SOC(%)
0	0 - 19.5	9	55.5 - 60
1	20 - 23	10	60.5 - 65
2	23.5 - 26	11	65 - 70
3	26.5 - 30	12	70.5 - 75
4	30.5 - 35	13	75.5 - 80
5	35.5 - 39.5	14	80.5 - 85
6	40 - 44.5	15	85.5 - 92
7	45 - 50	16	92.5 - 95
8	50.5 - 55

Energy Flow

(1)	It displays graphical energy flow of an HEV vehicle to inform the driver of the vehicle information.

(2)	It leads to economic driving by showing the energy flow diagram by means of intuitive images.

(3)	HCU module receives operation mode CAN signals to implement any relevant animation.

No	Definition	Graphic	Remark
1	Vehicle stopped		-
2	Motor driving force Driving the vehicle state		Battery → Wheels
3	Motor and Engine driving force for driving the state vehicle		Batteries → Wheels Engine → Wheels
4	Engine powered by state of the vehicle is the only driving force		Engine → Wheels
5	Engine stops at the high-voltage battery charge state		Engine → Batteries
6	Due to the high voltage battery charging regenerative braking		Wheels → Batteries
7	Engine Friction braking conditions using a vehicle		Wheels → Engine
8	Engine amount of secondary high-voltage battery charging while driving		Engine → Wheels Engine → Batteries
9	Motor Engine is to charge the battery in the vehicle driven by the state		Engine → Batteries Batteries → Wheels
10	Engine Generation / Regeneration		Engine → Batteries Wheels → Batteries
11	Engine Brake / Regeneration		Wheels → Engine Wheels → Batteries

Hyundai Ioniq (AE) 2017-2024 Owner's Manual: Day/night rearview mirror, Blue Link® center

Day/night rearview mirror Make this adjustment before you start driving and while the day/night lever is in the day position. Pull the day/night lever towards you to reduce glare from the headlights of the vehicles behind you during night driving. Remember that you lose some rearview clarity in the night position...
