Sebring Coupe V6-3.0L VIN H (2005)
Information Bus: Description and Operation
COMMUNICATION METHOD
As shown, signal wires used exclusively for transmitting multiplex signal data connect the ETACS-ECU, front-ECU, column switch (incorporating the
column-ECU) and sunroof motor assembly (incorporating the sunroof-ECU) and these components communicate with each other.
TONE ALARM FUNCTION
IGNITION KEY REMINDER TONE ALARM FUNCTION
When the driver's door is opened (driver's door switch ON) without removing the ignition key [ignition switch to "LOCK" (OFF) position], the tone
alarm will sound intermittently to remind the driver that the ignition key has not been removed.
LIGHT REMINDER TONE ALARM FUNCTION
When the driver's door is opened (driver's door switch ON) with lighting switch (taillight switch or headlight switch) in the ON position and ignition
switch in the "LOCK" (OFF) or "ACC" position, the tone alarm will sound continuously to remind the driver that the lights (taillights or headlights) are
ON. This function does not work if the taillights or headlights are switched off through the headlight automatic shutdown function. In addition, the
ignition key reminder tone alarm function has a priority over this function.
DOOR AJAR TONE ALARM FUNCTION
If any of the doors are open, with ignition switch "ON" and with vehicle running at the speed of 8 km/h (5 mph) or more, ETACS-ECU makes buzzer
sound.
LOW WASHER FLUID LEVEL TONE ALARM
If 10 seconds have passed after ignition switch has been turned "ON," and then, washer fluid level switch remains at the position "ON" (alarms for
washer fluid level getting low) for two seconds or more, ETACS-ECU makes buzzer sound. Buzzer sounds just once after setting ignition switch to the
position "ON."
SEAT BELT TONE ALARM FUNCTION
If the seat belt is unfastened (the seat belt switch: ON) for ten seconds after the ignition switch has been turned on for 60 seconds or more, or the vehicle
speed reaches 8 km/h (5 mph) or more while the seat belt is unfastened (the seat belt switch: ON), the ETACS-ECU will sound the tone alarm (the tone
alarm will sound for five seconds every three seconds 12 times). If the seat belt is fastened or the ignition switch is turned off while the tone alarm is
sounding, the tone alarm will stop sounding.
LOW FUEL LEVEL TONE ALARM FUNCTION
If seven seconds have passed after ignition switch has been set to the position "ON," and then, low fuel level signal (low fuel level alarm light) from
ECM or PCM, is turned "ON," ETACS-ECU makes buzzer sound. Buzzer sounds just once after setting ignition switch to the position "ON."
CENTRAL DOOR LOCKING SYSTEM
OPERATION
-
When the driver's inside lock knob is locked or unlocked, the lock relay inside the ETACS-ECU turns on to lock or unlock all doors.
-
With all the doors locked, turning the key in the driver's door unlocks the door. Turning it again makes the door unlock relay close to send a signal
for unlocking all doors.
-
When the door lock switch (built into the power window switch) is operated, the lock or unlock relay inside the ETACS-ECU is turned on to lock
or unlock all doors.
FORGOTTEN KEY PREVENTION FUNCTION
-
If the driver's door is open (driver's door switch: ON), when the key is inserted in the ignition switch (key reminder switch: OFF), the
