1. Seat Belt Warning Function The driver side indicator in the Cluster is activated by 'Driver SeatBelt Indicator Status' CAN signal and the assistant side indicator is activated by the IPM output 'Assist SeatBelt Indicator'. Seat Belt Warning Sound: In case of Driver side 6sec Indicator, the cluster module operates it after receiving 'Driver SeatBelt Indicator Status' from the IPM. So if the IPM sends 'Driver SeatBelt Indicator Status = blinking' over 6sec then the IPM sounds buzzer warning one more time. Frequency: 800 Hz Sound period: T2 = 1sec Sound duration: T1 = 6sec Assistant Seat Belt Indicator: Duty: 50% Period: T2 = 1sec Duration: T1 = 6sec Driver Seat Belt IND and Buzzer Sound Logic Condition While IGN1 On status if IPM detects seatbelt transition UNFASTEN --> FASTEN, BUZZER SOUND stops immediately but DRIVER SEAT BELT IND continues working for the remained time. While IGN1 ON status if there is a seatbelt transition FASTEN --> UNFASTEN, DRIVER SEAT BELT IND and BUZZER SOUND are always activated for one period. If IGN1 is turned OFF during SEAT BELT WARNING, the DRIVER SEAT BELT IND and BUZZER SOUND stops immediately. If IPM detects IGN ON signal regardless of seatbelt status, DRIVER SEAT BELT IND should be triggered for defined timing for IND check but Buzzer SOUND should be played only in case of unfastened seatbelt.
2. Key Operated Warning Condition: (Key IN = ON or ACC=ON or FOB IN=ON) and (IGN1 IPM=OFF, IGN2 IPM=OFF, ALT L=OFF) Input: Driver door switch = Open Output: Buzzer = On
3. Parking Brake Warning Condition: (IGN1 = ON) and (10km/h = vehicle speed) Input: Parking Brake = On Output: Buzzer = On
4. Key Learning Sound When each Key's learning is ended, magnetic buzzer is operated, every one time.
5. Key Battery Discharge Warning If the terminal state changed from IGN or Engine Running to OFF with Fob absence in fob holder, then the IPM generates this warning. "Steering Column Not Locked Warning" warning sound.
6. Steering Column Not Locked Warning If all terminals are Off and the ESCL is not locked while the last command was a block command, the IPM generates this warning.
7. Steering Column IS Not UNLocked Warning After SSB (Start Stop Button) press, If the steering lock is not unlocked due to any failure except ESCL failure, then the IPM generates a corresponding warning.
8. SMK System Buzzer Warning Warning sounds are necessary for the SMK (smartkey) system in the following cases: FOB IN means FOB is inserted in FOB holder. ID out warning While the valid Fob is not inside car, if all doors are closed at IGN or ACC state, the buzzer warning (external and internal) sound is activated for 3sec. Deactivation of ID While the valid Fob is inside car and the vehicle enters ATWS armed, the buzzer warning (internal) sound is activated for 5sec. The "Deactivation of IDs" warning sound stops, when ATWS disarmed. Door Lock warning 1 While the valid Fob is founded near by outside handle and all doors are closed at ACC or IGN state without Fob IN, the buzzer warning (external) sound is activated for 3sec. The "Door lock warning1" sound stops, when the activity timer elapsed or (ACC=OFF) or (NOT ALL DOORS CLOSED) or (FOB IN). Door Lock warning 2 While the valid Fob is founded near by outside handle and any door open at terminal OFF state without Fob IN, the buzzer warning (external) sound is activated for 3sec. The "Door lock warning2" sound stops, when the activity timer elapsed or (ACC=ON) or (IGN1 = ON) or (ALL DOOR CLOSED) or (FOB IN). Door Lock warning 3 While the valid Fob is inside car and all doors are closed at terminal OFF state without FOB in, the buzzer warning (external) sound is activated for 3sec. The "Door lock warning3" sound stops, when the activity timer elapsed or (ACC=ON) or (IGN1 = ON) or (NOT ALL DOOR CLOSED) or (FOB IN).
9. SMK Key Reminder Warning 2 (SMK Option Only) Any door opens at terminal OFF state without FOB in. After transition to all door closed within 500msec, if the valid Fob is in side car and all door locked then IPM transmits SMK key reminder warning 2 command (SMK Warning
10. SMK System Lamp Warning (SMK Option Only) While the valid Fob is not inside car and 3Km/h is not set (3km = Off) at (Fob In = Off, ACC = On) or (IGN1 IPM = On) then send SMK Warning IND = (SMK Lamp Waring).
11. SMK System Trunk Warning (SMK Option Only) While the valid Fob is inside trunk and the trunk open state, the IPM detects the trunk closed state then IPM transmits trunk warning command (SMK Warning). If a 5sec trunk re-opening warning sound is in progress and there is another trunk re-opening warning sound request before the end of the previous 5sec buzzer, the warning is re-triggered for 5 seconds.
12. ESCL System Indicator Warning The IPM sends SMK Warning. IPM send SMK Warning IND to CLU (Cluster) and PDM by state sending type. Shift "P" Warning ID This warning appears when the SSB is pushed to stop the engine or to switch off all terminals with the A/T gear M lever in any position except the 'P' position. If this warning appears, the terminal system is remains in the [ACC] position state instead of the OFF position. Key Battery Discharge Warning This indicator appears when the Key battery is running out of power. Steering Column Not Unlock Warning If the steering lock is not unlocked due to the load applied to the steering wheel when pushing the SSB, the IPM generates a corresponding warning and the SSB indicator light blinks blue. Steering Column Not Locked Warning If all terminals are Off and the ESCL is not locked while the last command was a block command, the buzzer warning (internal) sound is activated. ESCL ECU Fail Warning This Indicator appears when the ESCL ECU failure is detected in the OFF state. the buzzer warning (internal) sound is activated. Engine Start Operation Indicator This indicator appears when the system is in the [ACC] or [IGN] state. Authentication Failed Warning The SSB is operated and no valid fob in interior. There are two patterns for situation; Pattern 1 is that the user presses the SSB to go to [ACC] state from [OFF]. And pattern 2 is that the user presses the SSB to start Engine in [OFF] or [ACC] or [IGN] states. FOB Key Removal Indicator User turns all terminals off with fob key in holder. There are two patterns for situation; Pattern 1 is that the user turns all terminals off from [IGN] state with Fob key in holder. And pattern 2 is that the user turns all terminals off from [IGN - Engine] with Fob key in holder.

Scheme 30

Lamp Control

The Lamp function includes the sub functions for On/Off control of the following devices

Scheme 31

1. Tail/Head Lamp
2. Fog Lamp

Tail/Head Lamp Control

Tail/Head Lamp sub functions are controlled by MFSW, IPM and FAM.

The Tail Lamps are turned on and off by Tail Lamp Switch or Auto Light.

The Head Lamps Low and High are turn on and off by Head Lamp Switch or Auto Light.

The DRL controls Head Lamp High when the engine is running.

The Head Lamp High is on when the Passing switch is on.

1. MFSW: lamp switch control Input detection of lamp switches (Lamp Off, Tail Lamp, Head Lamp Low, Head Lamp High, Passing, and Auto Light) Generate Light Switch Status data compounding by some switch input (Lamp Off, Tail Lamp, Head Lamp Low, Auto Light) for FAM and IPM. Generate Head Lamp High switch data for FAM Generate Passing switch data for FAM Send Light Switch Status, Head Lamp High Switch and Passing Switch data via CAN
2. IPM: Auto light control The IPM detects Input of Auto Light Sensor level. When IGN switch is ACC or IGN or cranking state, the IPM generates CAN signal Auto Light Out Status for FAM. * Behaviour for normal state From ACC ON state, the IPM monitors the range of this supply and raises up a failure as the supply's voltage is out of range (that is less than 4 Volts, more than 6 Volts). The filtering of the error is 300ms to rise up this one, and also 300ms to clear this one. Then this failure occurs and as long as this is present, the head lamp low must be turned on, that IPM sends (Auto Light Out Status), without taking care about the sunlight level provided by the sensor.
3. FAM: Auto Light Control The FAM controls tail and head lamp low with filtering time according to (Auto Light Out Status) The FAM controls continuous turn on mode. * Behaviour for normal state If the state of IGN Switch FAM is IGN or ST and Light Switch Status state is Auto Light Switch On, then TAIL LAMP RELAY output and HEAD LAMP LOW RELAY output are controlled by FAM with filtering time in accordance with Auto Light Out Status state change that is AUTO LIGHT Sensor's INPUT from IPM and according to specifications for each lamp described in below.
4. FAM: Tail Control The FAM memorizes the AUTO CUT state in EEPROM and describes the following features. Turn on and off Tail Lamp by Light switch. Turn on and off Tail Lamp by Auto Light out Status. Automatically cut the Tail Lamps if the driver forgets to turn them off. Output control of Tail Lamp relay Generate Tail Lamp Activity data.
5. FAM: Head lamp Control Turn on and off Head Lamp Low by Light Switch Status. Turn on and off Head Lamp High by Light Switch Status. Turn on and off Head Lamp Low by Auto Light out Status. Turn on and off Head Lamp High and Low by Passing Switch. Output control of Head Lamp Low Relay. Output control of Head Lamp High IPS by PWM Control. Generate Head Lamp High IND data for CLU. Generate Head Lamp Low IND data for CLU. Generate Head Lamp High Activity data for Front Fog Lamp. Generate Head Lamp Low Activity data for Front and Rear Fog Lamp.
6. FAM: DRL Control Turn on and off DRL by some condition, using Head Lamp High DRL Relay outputs with dimmed intensity compared with normal High Beam operation.

Fog Lamp Control

Fog Lamp sub functions are controlled by FAM.

1. Turn Front Fog Lamp on and off by control of Front Fog IPS.
2. Front Fog Lamp on when only Tail Lamp on (Head Lamp on for North America).
3. Turn Rear Fog Lamp on and off by control of Rear Fog IPS.
4. Rear Fog Lamp on when only Front Fog Lamp on or Head Lamp on.
5. Generate Front Fog Lamp Activity data for Rear Fog Lamp.

Turn Signal Lamp Control

The Turn Signal Lamp Control function controls turn signal lamps and indicators.

Scheme 32

Scheme 33

Scheme 34

1. FAM: Normal Operating Condition While IGN Switch FAM is IGN state, if Turn Signal RH Switch or Turn Signal LH Switch or Hazard switch is ON then turn signal outputs are turned ON following the switch input (LEFT, RIGHT or HAZARD).
2. FAM: Double Blinking Condition In case of activation of hazard the fault detection will be able to detect the failure only if 3 bulbs are broken-down. The double blinking works at IGN Switch FAM is IGN state, double blinking for Hazard. In case of turn signal activation when one of the FRONT or REAR is broken-down (Lamp failure), the turn signal blinks with double frequency.
3. FAM: SCG (SHORT CIRCUIT TO GND) Fault Condition If The FAM detects Short circuit to Ground, then FAM turns off the OUTPUT The fault detection is carried out continuously, until fault is confirmed by FAM. Once FAM confirms SCG, FAM keeps the fault condition until flasher trigger condition is changed.

Wiper Function Control

Inform wiper module current operation mode to Rain Sensor and transfer Rain sensor command to ECW via CAN network.

The Wiper Control FAM manages the Rain sensor communication.

Scheme 35

Behaviour For Normal State

1. Rain Sensing Wiping If without the rain sensor option, the FAM can't receive Wiper Aut oSW from the multi function switch via CAN.
2. The FAM shall output the various modes according to the following. No. Wiper Mode Duty Cycle 1 Off, MIST, INT, LOW or HIGH speed mode 6% +3/-2% 2 (Auto mode) Sensitivity 0 (Step 5) 12% +3/-2% 3 (Auto mode) Sensitivity 1 (Step 4) 18% +3/-2% 4 (Auto mode) Sensitivity 2 (Step 3) 24% +3/-2% 5 (Auto mode) Sensitivity 3 (Step 2) 30% +3/-2% 6 (Auto mode) Sensitivity 4 (Step 1) 36% +3/-2% 7 Washer mode 42% +3/-2% 8 (Auto mode) Sensitivity 4 (Step 1) with inwipe 66% +3/-2% 9 (Auto mode) Sensitivity 3 (Step 2) with inwipe 72% +3/-2% 10 (Auto mode) Sensitivity 2 (Step 3) with inwipe 78% +3/-2% 11 (Auto mode) Sensitivity 1 (Step 4) with inwipe 84% +3/-2% 12 (Auto mode) Sensitivity 0 (Step 5) with inwipe 90% +3/-2% 13 Sensor test mode (For TRW use only) 54% +3/-2% OFF, MIST, LOW, and HIGH/Washer operation in Non AUTO mode. MIST, LOW, and HIGH shall be interpreted as driver requested manual modes. The RAIN SENSOR output during these switch positions shall be an "Off" or "Rain Detected" duty cycle. AUTO (Sensitivity 0 - 4) One of five sensitivity switch positions will signal the RAIN SENSOR to operate in automatic mode. Sensitivity 0 refers to the least sensitive state (the slowest, step5) while Sensitivity 4 refers to the most sensitive state (the fast, step1). WASHER (Washer operation only in AUTO mode by washer Switch) WASHER signals the RAIN SENSOR that the Wash Paddle is being depressed and that the wiper system is going through a PROGRAMMED or DEMAND WASH cycle. The RAIN SENSOR output during this switch position is an "Off" or "Rain Detected" duty cycle. The RAIN SENSOR will ignore washer fluid spray. In-wipe The in-wipe signal specifies when received (Wiper Park Position) from ECW. In-wipe information is provided so the RAIN SENSOR can assure accurate delay times and smooth operation while in the automatic mode.
3. Rain Sensor to FAM The Sensor shall output the various modes according to the following: OFF OFF is the Sensor's request to the wiper controller to stop wiping. Fault 1 - Internal Fault Detected Internal Fault Detected shall attempt to be asserted by the Sensor whenever an internal or onboard software or hardware fault is detected. This signal implies that, through on-board diagnostics, the Sensor has detected a problem within the Sensor module and, therefore, has little or no confidence in its' ability to function properly. Fault 2 - Glass Attachment Fault Detected Glass Attachment Fault Detected is asserted when the Sensor module, through internal light intensity monitoring, detects an attachment problem between the Sensor and windshield. Fault 3 - No Input Signal Present No Input Signal Present is asserted when the Sensor cannot detect a usable input signal from the wiper control for a minimum of 0.5 seconds. Rain Detected Rain Detected shall be asserted in place of an OFF output in all modes when rain is detected and for 5 minutes following rain detection. Rain Detected is defined as when the internal Rain Intensity variable is greater 40. Low Speed Request A Low Speed Request shall be asserted in the automatic mode when the Sensor determines that the wiper system should be operating in Low speed. A minimum of 5 consecutive output periods and not more than 10 shall be sent to request a single wipe (command wipe). High Speed Request A High Speed Request shall be asserted in the automatic mode when the Sensor determines that the wiper system should be operating in High speed. Sensitivity Performance Sensor sensitivity (ability to respond to various moisture accumulation conditions) performance shall meet the nominal wiper period. Output Wipe Mode Smoothing/Response Time The Sensor processing algorithms shall contain smoothing characteristics that prevent erratic wipe transitions. Delay time changes, transitions between delay and continuous low speed, and transitions between continuous low speed and continuous high speed shall be smooth.

Automatic Mode

When the wiper switch is moved to AUTO position (Wiper Auto Switch=ON & Wiper Int Switch=ON) and (IGN Switch FAM = IGN), the Rain sensor is considered to be in "AUTOMATIC" mode.

1. If the wiper switch has been left in AUTOMATIC Mode with the vehicle ignition OFF, and then the vehicle ignition switch is turned on, the FAM transmits single wiping command.
2. The FAM transmits a single wiping command whenever rain has been detected (Rain Detected signal from Rain sensor) and the wiper switch is moved to the AUTO position. But The FAM does not transmit single wiping command when the wiper switch is moved to the AUTO position and OFF signal is being received from Rain sensor. But if the wiper switch is moved to AUTO position for the first time since vehicle ignition switch is turned on then the FAM transmits single wiping command regardless of Rain Detected or OFF signal.
3. Sensitivity Adjustment Function The drive may adjust the rain sensor performance by adjusting the sensitivity input. When in AUTOMATIC mode, the FAM transmits single wiping command each time the SENSITIVITY is adjusted upward to a more sensitive setting (downward more then one step). This single wiping command will only be transmitted if Rain Detected signal is being received from the Rain sensor. If the sensitivity adjustment is adjusted upward more than one sensitivity, the FAM will transmit single wiping command unless the time between Increases is more than 2 seconds.

Scheme 36

1. In case of IGN Switch FAM = IGN & (Tail Lamp LH=ON and Tail Lamp RH=ON) status, if head lamp washer Switch input is detected, head lamp washer output is turned ON.
2. In case of (IGN Switch FAM = IGN & Head Lamp Low Relay=ON) status, if washer Switch input is detected more T1 time, head lamp washer output is turned ON.
3. When a washer request arrived during washer activation, the second it's not take in account. T1, T2, T3 Time is implemented in the FAM EEPROM.
