Simplified Wiring System Operation
OPERATION
TONE ALARM FUNCTION
IGNITION KEY REMINDER TONE ALARM FUNCTION
When the driver's door is opened with the ignition key inserted in the ignition key cylinder (ignition switch is in the OFF position,) the tone alarm sounds intermittently to indicate that the ignition key has not been removed.
LIGHT REMINDER TONE ALARM FUNCTION
When the taillights or headlights are ON, if the ignition key is removed and the driver's door is opened, a tone alarm will sound continuously to warn that the light is illuminated.
However, if the taillights or headlights have been turned off by the headlight automatic-shutdown function, the tone alarm will not sound.
SEAT BELT TONE ALARM FUNCTION
If any of the following conditions is met with the ignition switch at "ON" or "ST", the ETACS-ECU sounds the tone alarm by using the driver's seat belt switch signal and the vehicle speed signal sent from the combination meter.
- Sounds the tone alarm for six seconds when the ignition switch is turned "ON" with the seat belt switch on (the driver's seat belt is not fastened). This is called "Timer function".
- Sounds the tone alarm 12 cycles (after 0.5 second) if any of the following conditions is met when sixty seconds or more have elapsed since the ignition switch is turned "ON". One cycle consists of five-seconds "on" and then three-seconds "off".
1. The vehicle speed has reached 8 km/h (5 mph) while the seat belt switch is turned on (driver's seat belt is not fastened) with the ignition switch "ON.
2. The seat belt switch has been turned on (driver's seat belt has not been fastened) for at least ten seconds while the ignition switch has been turned "ON" and the vehicle speed has been 8 km/h (5 mph) or more.
NOTE:
Once the tone alarm has sounded 12 cycles, it does not sound again until the vehicle speed reduces to 3 km/h (2 mph) or less even if any of the following conditions is met.
- The tone alarm stops sounding if the ignition switch or the seat belt switch is turned off (the driver's seat belt is fastened) while the timer operation is active.
DOOR AJAR WARNING BUZZER
The buzzer is sounded 4 times by the ETACS-ECU to warn the driver if any door is open when the ignition is switched ON and the vehicle speed reaches 8 km/h (5 mph) or faster.
The buzzer will continue to sound for 4 times even if the ignition, door status, or vehicle speed requirements are not maintained.
MULTI-CENTER DISPLAY (MITSUBISHI MULTI COMMUNICATION SYSTEM) OPERATION TONE
The ETACS-ECU sounds the buzzer when the buzzer signal is sent from the multi-center display.
TURN-SIGNAL LIGHT BUZZER
The ETACS-ECU sounds the buzzer in sync with the turn-signal lights or hazard warning lights.
CENTRAL DOOR LOCKING SYSTEM
CENTRAL DOOR LOCKING SYSTEM OPERATION
Door unlocking by operating the driver's door lock key cylinder:
- When the ignition key is inserted in the driver's door lock key cylinder and turned clockwise to unlock the driver's door, the ETACS-ECU operates its door unlock relay and passes a current through the door lock actuator of the driver's door for 0.25 second to unlock only the driver's door.
Door locking or unlocking by operating the driver's or front passenger's door lock switch:
- When the door is locked by the driver's or front passenger's door lock switch, the ETACS-ECU operates its door lock relay and passes a current through the door lock actuators of all doors for 0.25 second to lock all doors.
- When the door is unlocked by the driver's or front passenger's door lock switch, the ETACS-ECU operates its door unlock relay and passes a current through the door lock actuators of all doors for 0.25 second to unlock all doors.
- When the door is locked and unlocked by driver's or front passenger's door lock switch consecutively, the ETACS-ECU operates its door lock relay and passes a current through the door lock actuators of all doors for 0.25 second to lock all doors. Then, the ETACS-ECU operates its door unlock relay and passes a current through the door lock actuators of all doors for 0.25 second to unlock all doors. Due to this, there may be a time lag between the driver's or front passenger's door lock switch actuation and the time when all doors are unlocked.
FORGOTTEN KEY PREVENTION FUNCTION
- If the driver's door is locked while it is open and when the key is still in the ignition key cylinder, approximately 0.3 second later the ETACS-ECU activates the unlock relay output for 0.25 second to prevent the door from being locked with the key inside the vehicle. In addition, if locking the door was not prevented, a re-try current is sent (an unlock relay output ON is sent for 0.25 second up to 5 times including the first attempt).
- If the passenger's door and driver's door are locked while the passenger's door is open and when the key is still in the ignition key cylinder, approximately 0.3 second later the ETACS-ECU activates the unlock relay output for 0.25 second to prevent the door from being locked with the key inside the vehicle. In addition, if locking the door was not prevented, a re-try current is sent (an unlock relay output ON is sent for 0.25 second up to 5 times including the first attempt).
POWER WINDOW RELAY CONTROL
POWER WINDOW RELAY OPERATION
If the ignition switch is turned to "ON" position, the power window relay is energized to activate the power windows.
POWER WINDOW TIMER FUNCTION
Even after the ignition is switched off, the ETACS-ECU keeps the power window relay activated for approximately 30 seconds, enabling raising and lowering of the power windows by using the power window switches. After approximately 30 seconds, the power window relay is deactivated.
During this timed operation, if the driver or passenger doors are opened, the power window relay is deactivated from that moment.
KEYLESS ENTRY SYSTEM
KEYLESS ENTRY HAZARD ANSWER BACK FUNCTION
If the keyless entry transmitter is used to send a lock signal to the ETACS-ECU, all doors, the liftgate, and the glass hatch are locked and the hazard warning lights flash once. If an unlock signal is sent, the driver's door is unlocked first, and if a second signal is sent, all doors, the liftgate, and the glass hatch are unlocked. Each time the unlock signal is sent, the hazard warning lights flash twice.
KEYLESS ENTRY HORN ANSWER BACK FUNCTION
If the keyless entry transmitter is used to send 2 lock signals to the ETACS-ECU, the first signal locks all doors, the liftgate, and the glass hatch, while the second signal sounds the horn once.
TRUNK UNLOCK FUNCTION
Press the "TRUNK" button twice within 5 seconds and the trunk lid will be unlocked.
TIMED LOCKING MECHANISM
After unlocking the doors with the keyless entry transmitter, if no doors are opened and if the ignition key is not inserted, the ETACS-ECU automatically locks the doors in 30 seconds.
SUNROOF CONTROL
SUNROOF TIMER FUNCTION
The ETACS-ECU enables opening and closing of the sunroof for 30 seconds after the ignition is switched off. During this timed operation, if the driver's or front passenger's door is opened, the sunroof timer function is deactivated from that moment.
WINDSHIELD WIPERS AND WASHERS
LOW-SPEED WIPER, HIGH-SPEED WIPER CONTROL
- When the ignition switch in at the ACC or ON position, and the windshield low-speed wiper switch of the column switch is turned ON, the front-ECU turns ON the windshield wiper drive signal, turns OFF (LO) the windshield wiper speed relay, and operates the windshield wiper at low-speed.
- When the windshield high-speed wiper switch is turned ON, the windshield wiper drive signal is turned ON, the windshield wiper speed switching relay is turned ON (HI), and the windshield wiper is operated at high-speed.
INTERMITTENT CONTROL
ETACS-ECU uses the dial position of the variable intermittent wiper control switch and the vehicle speed signal sent by the combination meter to calculate the interval to be sent to the front-ECU. The front-ECU determines the intermittent time from the input SWS data signal, and turns ON the windshield wiper drive signal. When the wiper is at the STOP position, the windshield wiper auto-stop signal goes OFF to turn OFF the windshield wiper drive signal. After the intermittent time from when the windshield wiper drive signal turned ON, the windshield wiper drive signal is turned ON again and the above operation is repeated.
MIST WIPER CONTROL
When the ignition switch is in the ACC or ON position, and the windshield mist wiper switch of the column switch is turned ON, the front-ECU turns ON the windshield wiper drive signal.
At the same time, the wiper speed switching relay is turned ON (HIGH-SPEED). While the windshield mist wiper switch is ON, the windshield wiper will operate at high speed. Then, if the windshield mist wiper switch is turned off, the wiper operates at low speed until it stops at the predetermined park position.
When the windshield mist switch is turned on briefly, the wiper operates once at low speed.
At the point the windshield mist switch is turned ON, if the windshield wiper has been operating intermittently, the same operations as the above will be performed while the windshield mist wiper switch is ON. After the windshield mist wiper switch goes OFF, the intermittent operations will be set again after the windshield wiper auto-stop signal last is turned ON.
WASHER CONTROL
When the ignition switch is in the ACC or ON position, and the windshield washer switch of the column switch is turned ON, the front-ECU turns ON the windshield washer relay. The windshield wiper drive signal is turned ON in 0.15 second until 2 seconds after the windshield washer switch goes OFF to operate the windshield wiper continuously. When the windshield washer switch is turned ON, if the windshield wiper is operating intermittently, intermittent operations will be continued after continuous operations.
HEADLIGHT
HEADLIGHT AUTOMATIC SHUTDOWN FUNCTION
Even if the lighting switch (taillight switch or headlight switch) is ON, the headlights and taillights will automatically go off in the following conditions to prevent the battery from discharging:
When the ignition key is turned from "ON" to "LOCK" (OFF) or "ACC" position with the lighting switch turned ON, and this state continues for three minutes, the light will automatically be turned off. If the driver's seat door is opened during these three minutes, the light will go off one second later.
HIGH-BEAM INDICATOR
At the same time that the high-beams are illuminated, the ETACS-ECU sends a signal to illuminate the high-beam indicator via the CAN bus line. The combination meter receives the transmitted signal and turns the high-beam indicator on and off.
DAYTIME RUNNING LIGHT FUNCTION
The ETACS-ECU outputs the daytime running light forced-OFF signal to the front-ECU based on the input signal sent via CAN communication. The front-ECU controls illumination and extinction of the daytime running light according to the daytime running light forced-OFF signal.
Illumination control of daytime running lights
- If the engine is started when the parking brake is not pulled, the headlights illuminate with the brightness reduced.
- If the engine is started while the parking brake is pulled, the daytime running light function OFF mode is entered and the headlights do not illuminate. If the parking brake is released, the OFF mode is cancelled and the headlights illuminate.
FLASHER TIMER
TURN-SIGNAL LIGHT
The turn-signal light output (flashing signal) is turned ON when the ignition switch is ON and the turn-signal light switch is ON (LH or RH). If the front turn-signal light or rear turn-signal light bulb has burned out, the flashing speed increases to indicate that the bulb has burned out.
HAZARD WARNING LIGHT
Detects the signal where the hazard warning light switch input changes from OFF to ON, and reverse the flashing state according to this signal. The hazard warning lights toggle on and off whenever the hazard warning light switch is operated.
TURN-SIGNAL INDICATORS
At the same time that the turn-signal lights are illuminated, the ETACS-ECU sends a signal to illuminate the turn-signal light indicator via the CAN bus line. The combination meter receives the transmitted signal and turns the turn-signal light indicator on and off.
FOG LIGHT
FOG LIGHT
The fog lights will illuminate only when the fog light switch is operated while the low-beam headlights are on.
The fog lights will be switched off when any of the following conditions is met. The fog lights will also be switched off automatically by headlight automatic shutdown function.
- When the high-beam headlights are switched on, the fog lights will be switched off. If the low-beam headlights are switched on again, the fog lights will illuminate again.
- When the headlight switch is turned off while the taillights are on or the taillights and headlights are off, the fog lights will be switched off. If the low-beam headlights are switched on again, the fog lights will not illuminate again.
FOG LIGHT INDICATOR
At the same time that the fog lights are illuminated, the ETACS-ECU sends a signal to illuminate the fog light indicator via the CAN bus line. The combination meter receives the transmitted signal and turns the fog light indicator on and off.
INTERIOR LIGHT
ETACS-ECU makes it possible to force operation of all ON and OFF light switches in the overhead console (the map light, rear dome light, and trunk light). This function is assigned higher priority than the controls for the interior light switch that are performed when the doors are in certain positions.
- When the lights are forced on, the illumination level is 100 percent as all interior lights are switched on (the map light, rear dome light, and trunk light). Even when all lights are forced on, the interior light automatic shutoff function is active.
- When the lights are forced off, all interior lights are immediately switched off (the map light, rear dome light, and trunk light).
When the interior light switch is at DOOR position, the ETACS-ECU controls the interior lights as follows:
- When a door is opened with the ignition switch off, the interior lights up to a luminance of 100 percent. When a door is closed, the interior lights dims a luminance of 65 percent, and goes off 30 seconds later. However, if the ignition switch is turned ON or if a door is locked while the interior lights is dimming, the dome light will go off at that point.
- When a door is opened with the ignition switch ON, the interior lights up at a luminance of 100 percent. When all doors are closed, the interior lights go off.
- When the ignition key is removed with all doors closed, the interior lights up at a luminance of 100 percent, and goes off 30 seconds later. However, if the ignition key is inserted again or if a door is locked while the interior lights is lighting, the interior lights will go off at that point.
- To check keyless entry operations more easily, the interior lights will flash twice when doors are locked. When doors are unlocked, the interior lights up at a luminance of 100 percent, and goes off 15 seconds later.
INTERIOR LIGHT AUTOMATIC SHUTDOWN FUNCTION
Illuminated interior lights such as the front dome light, etc. (all lights using the dome light fuse as the power supply) will automatically go off in the following conditions to prevent the battery from discharging as a result of forgetting to turn off the lights or incomplete closing of the door.
- When the ignition switch is turned off and more than 30 minutes pass by with the interior light illuminated, the interior lights will go off automatically.
- When the ignition switch is turned off and one of the door switches remains open for 30 minutes continuously, the interior lights will go off automatically.
SEAT BELT INDICATOR
If any of the following conditions is met with the ignition switch at "ON" or "ST", the ETACS-ECU illuminates, flashes or extinguishes the seat belt indicator by using the driver's seat belt switch signal and the vehicle speed signal sent from the combination meter.
- Illuminates when the ignition switch is at "ON" and the seat belt switch is turned on (the driver's seat belt is unfastened).
- Flashes and illuminates the indicator 12 cycles (after 0.5 second) if any of the following conditions is met when sixty seconds or more have elapsed since the ignition switch is turned "ON." One cycle consists of five-second "flashing" and then three-second "illumination."
3. The vehicle speed has reached 8 km/h (5 mph) while the seat belt switch is turned on (driver's seat belt is not fastened) with the ignition switch "ON."
4. The seat belt switch has been turned on (driver's seat belt has not been fastened) for at least ten seconds while the ignition switch has been turned "ON" and the vehicle speed has been 8 km/h (5 mph) or more.
NOTE:
Once this timer operation has been activated, it will not be activated again until the vehicle speed reduces to 3 km/h (2 mph) or less even if any of the following conditions is met.
- The indicator stops illuminating if the ignition switch or the seat belt switch is turned off (the driver's seat belt is fastened) while the timer operation is active.
DOOR-AJAR INDICATOR LIGHT
The combination meter receives the signal sent from the ETACS-ECU about whether each door
(including the tailgate and glass hatch) is open or closed and turns the door ajar indicator light on and off. While the door ajar indicator is illuminated, the door ajar warning function is activated and the door ajar indicator light flashes 4 times. If the door remains open even after the 4 warning flashes, the door ajar indicator light will be illuminated again.
THEFT-ALARM SYSTEM
THEFT-ALARM SYSTEM OPERATION
When the theft-alarm system has been armed, if a door, trunk lid or hood is opened, the horn will sound and headlights flash (high-beam) intermittently for a period of 180 seconds.
This system is controlled by the ETACS-ECU.
