BCM FUNCTION
1. |
Vehicle speed
sensing intermittent wiper
Vehicle speed is determined by number of speed
sensor pulses input in one second. The current speed and the
previous speed for the vehicle is to be compared. The higher of the
two values is to be used in the intermittenttime calculation. The
previous value is updated every second.
When Ignition 2 is on and the wiper switch is
in the intermittent position, the wiper shall operate with speed
dependant intermittent time. A single wipe is achieved by driving
the wiper relay until the park switch is able to take over unless
the dwell time between wipes is too short. In this case it wouldbe
on all the time. This avoids unnecessary clicking of the wiper
relay.

Washer linkage
wiper
IG2 must be on for this function to
operate.
When the washer switch is on for more than 0.3
sec, the wiper output is activated immediately. The length of time
the washer switch is held foris then evaluated to determine the
number of swipes required.
If the washer switch is on for more than 0.2
but less than 0.6 sec, then wiper performs a single swipe.
Alternatively, if the washer switch is held for more than 0.6s then
the wipers must finish the current swipe theperform another two
swipes.
If washer switch is on less than 0.2 seconds
make no wiper action.
During intermittent wiping, a washer linkage
wipe has higher priority.
During start condition (IG1 on and IG2 off)
washer input to be ignored. This is to prevent quality problem of
single wipe occurring during startingof car.

Snow build up wiper
bounce prevention (snow mode)
Without this feature, as snow builds up at the
base of the windscreen, it becomes more difficult for the wiper arms
to completely reach the park position. Once the wipers have been
turned off and the wipers have returned to the park position, the
compacted snow is able to drive the wiper arms back up and
reactivate the park switch. This, in turn, drives the wiper arms
towardspark again and the cycle repeats itself.
This feature is required to prevent wiper
bounce from happening when snow has accumulated on the
windscreen.
Detection of wiper
bounce
If the BCM detects that the wipers have parked
more than a maximum amount times within a time period then wiper
bounce is detected. The maximum amount of times can be set in EEPROM
using the variable wipe snow parks. The time can also be set in
EEPROM using the variable wipe snow time. The units ofwipe snow time
is milliseconds.
Bounce
prevention
If wiper bounce has been detected then the
wiper bounce prevention relay is driven to open circuit. The wiper
bounce relay is in series with the park switch and thus can prevent
automatic parking. This relay is normally closed.
Termination of
bounce prevention
Termination is achieved by ceasing to drive
the wiper bounce relay to open circuit. Bounce prevention can be
terminated in the following ways:
A. |
Ignition off. The power source for the
wiper motor is derived from IG2, thus there will be no drive
to park with ignition off. As such bounceprevention is not
required. |
B. |
The wiper stalk has moved from the OFF
position. | |
4. |
Wiper motor stall
protection
This feature offers some protection to the
wiper motor if ice has frozen the wiper blades to the windscreen or
the wipers have jammed for some other reason. During low and high
wiper selection, no protection is offered sincethe stalk drives the
wiper motor directly.
If the wiper motor has not parked within wipe
stall time, then wiper motor is considered to have stalled. In this
case, the wiper bounce relayis driven to open circuit until either
of the following events occurs:
A. |
The ignition has been switched to the
off position. |
B. |
The wipers have returned the park
position by a manual operation (Low or high speed
selected) |
C. |
The wiper stalk has moved from the OFF
position. |
Wipe stall time can be set in EEPROM and it's
units are 100ms.
During INT operation, if the time between
initiating and concluding a wipe is greater than Wipe stall time
then the wiper motor is also considered to have stalled. In this
case, the current wipe is terminated and INT operationis cancelled
until either of the following events occurs:
A. |
The wiper stalk has moved from the OFF
position. |
B. |
The ignition has been switched
off. | |

Ignition key
reminder (Locking of key in vehicle prevention)
If the key is in the ignition and the
driver's door or assist door is open and the vehicle is locked
using driver's knob or assist knob, then the central locking
system will issue an unlock pulse of duration 1 second tothe
all doors thus preventing locking of the vehicle.
If a Knob remains locked, then the
central locking shall issue a maximum of 3 pulses of 0.5
second duration to unlock the vehicle. If during thesepulses,
the door lock knob becomes unlocked, stop the next
pulse.
If vehicle speed is greater than 3 km/h,
ignition key reminder function is disabled.

Key operated warning
(key in ignition reminder chime)
If the key is in ignition key cylinder and the
drivers door is opened, the chime bell sounds. This tone is the same
as the seatbelt warning chime and over speed warning chime. The

Crash detection -
Unlock
If IG1 is on and a crash signal is received,
send an unlock pulse to the door locks. Unlock signal must occur

ANTI-THEFT FUNCTION
1. |
Arm
function
Pressing the remote key lock button will
result in a 0.5-second pulse issued to lock all doors.
Pressing the remote keypad unlock button once
will result in a 0.5-second unlock pulse issued to unlock all
doors.
As part of the arming sequence the alarm first
enters a pre-armed state before falling into the armed state. During
this pre-armed state alarm triggers are ignored. Pre-armed state can
be reached from the alarmed state, the start inhibit state or the
disarmed state. Pre-Arming of the alarm can be achievedby a press of
the lock button on the remote key.
In the pre-armed state the visible and audible
warnings are disabled.
This system enters the armed state if it is in
the pre-armed state and, after 0.6 sec, check actuator lock and each
door, hood and tail gate close,and no door warning switch (no key in
ignition).
On entering the arm state, a single flash of
the hazard lamps is given, period of cycle 2 second, duty rate
50%.
If TX lock signal is received when a door,
tail gate or hood is open, then lock output is given and a flash of
hazard is not given.
After the armed state is entered, if a lock
signal is received then a single flash of the hazard lamps is given,
period of cycle 2 second, dutyrate 50%.
The armed state cannot be reached by locking
the car with the keys.

(of cycle), 50% duty rate. |
B. |
If door warning switch is on, IGN1 and
IGN2 are on in arm state, then arm state should be immediately
cancelled. This means that the driveris inside the vehicle
before pushing TX lock, so system should not
arm. |
In the disarm state the visible and audible
warnings are disabled and start is enabled.
In the disarm state, if TX key unlock command
is received, then the hazard lamps shall be flashed twice for period
of cycle 1 sec, 50% duty rate.
