ETACS
1. General
ETACS was applied for body electrical system control with existent vehicles even if gouge JM
Function that control is controlled to approach with a different car
Also, develop into Anti theft function to do control according to specification in ETACS.

2.1 Washer & intermittent wiper control Description & operating chart
1) When the ignition switch is "on", and if turn the washer switch on, wiper output become "on"
after 0.3sec. and turn the washer switch off, wiper output become "off" after 2.5 3.8sec.

change the wiper speed(with calculating intermittent time form vehicle speed)
1) Vehicle speed input calculates vehicle speed in the form of input pulse per a second.
60 [ km/h ] × 60 [ sec ]
1 [ pulse/sec ] = ------------------------------- 1.41 [ km/h ]
637 × 4 pulse
2) Vehicle speed output
Vehicle speed was counted input pulse per second, and than choose max. value (compare new

2) The lamp and the chime bell output are turned off if the ignition is "off" within the time.
As soon as the seat belt switch is "on" within the time, chime bell output is "off" immediately

2.4.1 Description
1) The output of defogger is "on" for 15 or 20min when the defogger switch is "on" in case
2) Make sure that defogger's output is "off" if the defogger switch is "on" again when the output is
3) Make sure that defogger's output is "off" if the alt l's changed to "low" when the output is still
"on" state.

As soon as door is closed (door switch is "off") 75% of light disappear and the rest decay
2) Make sure that no operation when time of door switch "on" is under 0.1 sec.
3) Make sure that analysis capacity is more than 32 step when light was decayed.
4) Make sure that the output is off as soon as the ignition switch is turned on during delaying and
decaying operation.

1 The room lamp lights “OFF” after lighting “ON” about 30 sec on condition that door is closed.
2 The room lamp prolongs light “ON” about 30 sec. Again, If the TX button unlocks during this
condition.
3 The room lamp keeps lighting “ON” in light “ON” when opening the door, the room lamp is back
to the delay function.
4 The room lamp lights “OFF” immediately and signals alarm if the keyless lock is.
Door lock function is operated automatically in bellow condition, when vehicle speed is more
than 40 Km/h while the engine is running.
1). IG. Switch is ON.
2.) Vehicle speed is more than 40 Km/h.
The signal of vehicle speed 40 Km/h is receive in ETACSCM.

2. If the ETACS receives the “Lock “ signal from transmitter when any one switch of all door
switches is open, it outputs “ON” the “Lock” output only, In this case, ETACS does not output
Hazard lamp “ON” and the vehicle does not “Armed”
3. The door is closed in the above “2” condition, ETACS output “ON” the Hazard lamp for 1sec.
And the vehicle is armed.
4. If lock button on the transmitter is pushed again under “Armed” condition, only Hazard lamp is
“ON” for 1sec. With maintaining armed condition.
Only the transmitter can make the “Armed” condition for the vehicle.
