1. Remote Control or Mechanism Key Lock

When defended, whether horn tweets is achieving by configuration, default not tweet.

When in undefended state, after BCM receiving valid remote control lock signal or driver’s side mechanism key lock signal,

if five doors and engine hood cover are all closed, four door are lock, two side turning lights twinkle once, twinkle period is 1s, in
which 0.5s on, 0.5s off, horn tweets 10ms. If BCM receiving remote control unlock order in twinkling period, light twinkling turns
into unlock twinkling procedure; if any other door is not closed after driver’s side door closed, lock motor works, turning light not
twinkles. After all doors are closed, perform confirmed action again (if there is key inserting, left front door open or central control
unlock/lock, cancel performing confirmed action again), namely two side turning light twinkle once, twinkle period is 1s, in which
0.5s on, 0.5s off, and horn tweets 10ms.

When in defended state, after BCM receiving valid remote control lock signal, BCM still carry out lock action, and perform

confirmed action, namely lock motor works, two side turning lights twinkle once, twinkle period is 1s, in which 0.5s on, 0.5s off,
and horn tweets 10ms.

2. Remote Control or Mechanism Key Unlock

When defended, after BCM receiving valid remote control unlock signal or driver’s side mechanism key unlock signal, four

doors unlock, BCM is undefended and perform confirmed action, namely two side turning lights twinkle twice and then off. Each
twinkle period is 1s, in which 0.5s on, 0.5s off, and horn tweets 10ms.

When undefended, after BCM receiving valid remote control unlock signal or driver’s side mechanism key unlock signal,

BCM is undefended and perform confirmed action, namely two side turning lights twinkle twice and then off.

In undefended state, after BCM receiving valid remote control unlock signal or driver’s side mechanism key unlock signal,

signal in 30s, carry out 500ms open tail door motor; When not open rear tail door over 30s or open rear tail door and then close
rear tail door, get into defended state again, and can’t unlock through tail door unlock signal.

In undefended state, if driver’s side door lock is locked, after receiving remote control opening tail door signal, receiving tail

door unlock signal in 30s, carry out 500ms open tail door motor; When not open rear tail door over 30s or open rear tail door and
then close rear tail door, get into defended state again, and can’t unlock through tail door unlock signal.

In undefended state, if driver’s side door lock is locked, after receiving remote control opening tail door signal, carry out

500ms opening tail door motor. Remote control opening tail door signal is prior to judgment of driver’s side door lock state.

6. Central Control Unlock/Lock Function

When in defended state or warning state, central control unlock/lock is invalid.

Central control switch control lock:

After BCM receiving central control lock switch signal in undefended state, if five doors and engine hood all are closed, then

lock four doors; if driver’s door is not closed, lock motor doesn’t work; if other doors or engine hood cover is not closed, lock
motor works. If lock motor is already in lock state, after BCM receiving central control lock switch signal, lock motor locks again.

Central control switch control unlock:

After BCM receiving central control unlock switch signal in undefended state, four doors motor unlock. If four doors are in

unlock state, after BCM receiving central control unlock switch signal, lock motor unlock again.

order immediately, and every unlock intermittence is 0.5s.

Auxiliary System

1. Rear Defrost Control

Rear defrost is mainly to be convenient for customer to remove frost and snow on rear windshield. Rear defrost function

description:

1) Each time BCM power on again, rear defrost output is closed.

2) Precondition of rear defrost output starting is that generator L terminal is valid.

3) Rear defrost switch signal transmitted by A/C controller is 200ms±5% high voltage. If prior to front and rear defrost output

closed, precondition of satisfying 2) described above, receive rear defrost switch signal once, rear defrost output opens; if prior to
front and rear defrost output open, receive rear defrost switch signal once, rear defrost output closes.

4) If always not receive rear defrost switch signal in the state of rear defrost output open, rear defrost output automatically

closes after lasting open for 20min.

2. Electrical Power Window Control

1）It can open when ignition switch is “ON”

2）Left front door doesn’t open but can start in 30s after ignition switch “ON”-“OFF”, if left front door opens or 30s time is

up, it closes, and can’t operate window to up and down.

3. Anti-pinching Motor Control

Through LIN bus, obey to LIN2.0 protocol, BCM is used as main node to use first route LIN. BCM displays corresponding
DTC after receiving corresponding signal, BCM displays DTC by judging WL_SWICHES_FAULT_FL.

4. Instruction Brake Signal Retransmission

After collecting instruction brake hardwire signal, BCM transmits instruction brake signal to CAN network. Detail description is

that: put down instruction brake to make vehicle in driving state, at this time switch is in hanged state; pulling up instruction brake is low
voltage (GND). BCM retransmits the state to CAN network meter.

5. Reversing Signal Retransmission

After collecting reversing signal, BCM transmits reversing gear position signal to CAN network.

When reversing gear position switch signal is valid Vbattery(KL.30), BCM transmits corresponding reversing gear position

ReverseSw=0x1 to CAN network; when reversing gear position switch signal is hanged, BCM transmits corresponding reversing
gear position ReverseSw=0x0 to CAN network.

6. Engine Hood Cover Signal Retransmission

BCM collects switch state of engine hood cover, and transmits corresponding CAN signal. When engine hood cover is open,

EMS should be not start.

Vehicle Body Anti-theft System

Vehicle body warning module is to realize warning function when vehicle in all kinds of abnormal states. Once warning

module is activated, audible and visual warning will start and remind customer to restrain starting function at the same time.

Warning function description (hazard warning light twinkle period is 1s, in which 0.5s on, 0.5s off):

1) When five doors and engine hood cover are all closed, use remote controller or driver’s side key to lock, hazard warning

light twinkle once, horn tweet 10ms, and in defended state; if driver’s side door is closed but other doors or engine hood cover is
not closed, use remote controller to lock door, door is locked, and at this time in defended waiting state; when all doors and engine
hood cover are all closed, hazard warning light twinkles once, horn tweens 10ms and get into defended state.

2) In defended state, five doors or engine hood cover open, or detect key inserting signal, vehicle will warning, and start

restrain relay output enable restrain starting; alarm whistle warning period: tweet T1(27±2sec), interval T2(10±1sec); tweet and
hazard warning light twinkle, warning for 3 periods (activate warning condition in 3 periods, not repeat calculate time). In the
condition of after warning 3 periods finishing and satisfied with defended, BCM gets into defended state, close tweet, and starting
restrain is closed; in the condition of after warning 3 periods finishing but not satisfied with defended, BCM gets into defended
waiting state, starting restrain still open, and activate warning condition not warning again.

7) When cutting off power supply and power on again, should be back to state before power off.

8) In the state of defended,, after carrying on undefended by remote control to unlock or driver’s side key to unlock, any door

or engine hood cover is not open in 30s or key insert into ignition lock and gets into defended state again.

9) When door and engine hood cover are closed and ignition switch inserting, carry on mechanism key to unlock, BCM carries

on unlock/lock output, but not carry on release defended function.

（III）Technical Parameter

1. Dormancy and Arouse Strategy

Three conditions satisfying at the same time can get into dormancy state：

1. Function satisfies dormancy condition;

2. CAN network satisfies dormancy condition;

3. LIN network satisfies dormancy condition.

In which function satisfies dormancy condition is：

1）Pull out key (this condition only for BCM without PEPS), there is no output in interior/exterior light and front/rear wiper,

there is no output request in door lock, anti-theft warning is not triggered, rear defrost is not open, and electrical power window is
not enabled. Last 60s and not change.

2）BCM is not in diagnosis mode

Before BCM getting into dormancy state, close all output signals. After getting into dormancy, all input signals can arouse
BCM from dormancy.

1）Switch signal: key inserting signal, IG2, IG1, ACC, hazard warning light switch, position light switch, mechanism key

lock/unlock switch signal, four doors+ engine hood cover+ rear trunk door state switch, rear trunk unlock switch, driver door lock
state, brake light switch, central control lock

2）CAN network （Including PEPS signal）：CAN interrupt arouse

3）RKE：There is remote control order

4）Diagnosis：Get into diagnosis mode

LIN arouse：After BCM arousing, LIN arouses.

2. Bus and Diagnosis

BCM supplies diagnosis of CAN-line to be convenient to maintenance of BCM. Diagnosis parts need the following functions:

· Parameter configuration （EEPROM read/write）

· Read DTC and clear DTC

· IO Control

· BCM controller information

· Off assembly line matching function

· ECU reset

BCM Device

BCM Device

91

Support one CAN bus to be as terminal nod on network, and don’t use network terminal (namely there is no terminal
resistance) in this project, one LIN bus to be as network main nod.

3. Voltage Abnormal Treatment Strategy

Normal working voltage of BCM is 9V-16V, and is carried on according to voltage management strategy established by

platform, and there are five states:

Normal voltage: 9-16V;

High voltage: higher than 16V momently, more than 40ms, but back to normal voltage in 440ms;

Low voltage: lower than 9V momently, more than 40ms, but back to normal voltage in 80ms;

Overvoltage: higher than 16V for long, more than 440ms, but don’t back to normal voltage;

Undervoltage: lower than 9V for long, more than 80ms, but don’t back to normal voltage;

1. Permit to output in the state of normal voltage/high voltage/low voltage

2. Close output in the state of overvoltage/undervoltage, recover output after system voltage back to normal.

Working voltage range of CAN network: 7-17.5V; working voltage range of LIN network: 7-16V; working voltage of
DTC: 8-16V.

4. Short Circuit and Open Circuit Protection Strategy

To high side output, detect short circuit and open circuit when On-stage. Once detecting short circuit or open circuit, counter

starts to counting, and when gets up to a certain value, it can be judged as open circuit or short circuit, and display corresponding
DTC. When detecting short circuit to power supply, once detecting short circuit to power supply, counter starts to counting, and
when gets up to a certain value, it can be judged as short circuit to power supply, and display corresponding DTC.

To SPI low side output, we only need to read diagnosis information of its storage to judge.

When in Off-stage, if diagnosis bit is low, it indicates output is open circuit, and counter starts to counting at the same time,

and when gets up to a certain value, it can be judged as open circuit, and display corresponding DTC. When in On-stage, if diagnosis
bit is high, it indicates output is short circuit to power supply, and counter starts to counting at the same time, and when gets up to
a certain value, it can be judged as short circuit to power supply, and display corresponding DTC.

5. Remote Control and Learning Code

To high configuration vehicle with PEPS, BCM doesn’t supply remote control function; to low configuration vehicle without
PEPS, BCM supplies remote control function.

BCM module includes remote control module, used radio frequency is 433.92MHz±100kHz. There are 3 buttons on remote

control key, including four doors unlock function, four doors lock function, and tail door unlock function.

When waiting for first key learning, right turning light is always on; when waiting for second key learning, right and left

turning light are always on; when learning success, right and left turning light are off. Through diagnosis order or when fixed time
is up, then exit learning state, remote control matching finish.

1. Once Routine can learn two keys.

2. If Routine time is more than 2 minutes, BCM exit this time Routine, and learned successful key will be wrote to EEPROM.

3. As long as key learn successfully, older keys will lose efficiency totally.

4. Press any key to learn code.

5. There are 2 exiting conditions: one is 2 minutes time, the other is diagnosis finishing order.

Ensure remote distance to be 20m. First develop without exterior antenna, and add exterior antenna if vehicle test not satisfy
with customer’s requirement.

I、Summary

（I）Structure Outline

1. Light Control Switch

Control left/right turning light, front headlight, front fog light, side turning light, overtaking light signal. In the mode of front

headlight working, there are two functions, namely high beam changing to low beam, low beam changing to high beam.

1） Turning light

There are two upward (right turning) and two downward (left turning) position on turning signal operating lever. These

positions are used to transmit turning signal.

Push operating lever upward or downward to send turning signal. When turning is over, operating lever will automatically

return. Arrowhead on combination meter will twinkle, displaying turning direction.

If need to send turning signal or changing road signal, pull operating lever upward or downward to the end. When turning

finish, operating lever will return automatically. When driver send turning or changing road signal, if turning arrowhead twinkling
too fast, it indicates signal light may be damaged, other driver will not see sent turning signal. If some lamp bulb is burnt, please
replace to avoid traffic. When driver send turning or changing road signal, turning arrowhead on combination meter not twinkle,
please check whether lamp bulb is damaged, and then check fuse.

2）Front headlight/Low beam light converter

If switch headlight from low beam to high beam, pull turning signal/multifunctional operating lever away from driver. When

high beam is on, if ignition switch is on, combination meter will display high beam light signal.

If switch headlight from high beam to low beam, pull turning signal/multifunctional operating lever to driver.

3）Overtaking twinkle

The function can send overtaking signal to drivers in front by high beam headlight. When use the function, pull signal/

multifunctional operating lever to driver until headlight high beam is on, and then loosen operating lever, headlight off.

4) Front fog light

After turning front fog light switch to “ON”, front fog light is on, and display front fog light signal on combination meter.

Only when front fog light switch is “ON” can operate rear fog light switch on combination meter to make rear fog light on.

2. Wiper Control Switch

1）Operate mode of controlling wiper (Wiping, intermittent, low speed, high speed).

When wiper is in intermittent position, there are five kinds of intermittent time regulating.

When turn ignition switch to ON, can operate front windshield wiper. Use right side operating bar of steering column to

operate front windshield wiper.

HI (High)：Turn operating bar to this position, can carry on high speed wiping.

LO (Low)：Turn operating bar to this position, can carry on stably low speed wiping.

INT (Intermittent): Turn operating bar to this position, can select delayed wiping one circulation.

Turning middle of wiper operating bar to LO can increase delayed time, and turning to HI can decrease delayed time. Only

when operating bar in INT can regulate wiping speed.

2）Front windshield washing liquid

In the condition of turning ignition switch to ON and pull front windshield wiper washing liquid operating bar to driver, to

wipe front windshield, and windshield wiper washing liquid will spray out from front windshield spraying nozzle.

3）Rear wiper switch

Turn switch to ON can open rear wiper function.

△ Note

In cooling weather, if front windshield not pre-heated, don’t use wiper, or washing liquid will be frozen on

front windshield, and shelter driver’s vision.

△ Note

When loosen operating bar, washer will stop work, but wiper will continue to wiping about 3 circulations,

and then stop or recovery to the used wiping speed.
