Ignition Key Reminder Tone Alarm Function

When the driver's door is opened and the driver's door switch is ON without removing the ignition key [ignition switch to LOCK (OFF) or ACC 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.

Seat Belt Tone Alarm Function

When the ignition switch is turned to the ON position without fastening the seat belts (seat belt switch OFF), the tone alarm will sound for approximately six seconds to warn the driver to fasten the seat belts. When the seat belts are fastened, the tone alarm will stop sounding.

Forgotten Key Prevention Function

1. If the driver's door is open (door switch turned ON), when the key is inserted in the ignition switch (key reminder switch turned OFF), the ETACS-ECU activates the door unlock relay for 0.25 seconds to prevent the door from being locked.
2. If you try to lock either the driver's or passenger's door when the passenger's door is open (door switch turned ON) and the key is inserted in the ignition switch (key reminder switch turned OFF), the ETACS-ECU prevents the doors from being locked by activating the door unlock relay for 0.25 seconds.

Power Window Timer Function

When the ignition switch is turned from the ON position to LOCK (OFF) or ACC position, the power windows can be operated for 30 seconds. If driver's or front passenger's door is opened for the 30 seconds, the power windows will be immobilized at that point.

Keyless Entry Answerback Function

If the RKE transmitter LOCK or UNLOCK switch is pressed while the ignition key is removed, the doors can be locked or unlocked. If the doors are closed, the hazard warning lights, the dome light and the horn will operate due to answerback function. Because of the answerback function, the hazard warning lights flash twice, and the horn sounds once, the dome light flashes twice when the doors are locked. Meanwhile, when the doors are unlocked, the hazard warning lights flash once and the dome light illuminates for 30 seconds. The hazard and the horn answerback functions can be cancelled by using the RKE transmitter.

Trunk Lid Opener Function

After TRUNK switch of the transmitter is turned ON twice within five seconds without ignition key in the key hole, ETACS-ECU makes trunk lid opener actuator open the trunk lid.

SEAT BELT WARNING LIGHT

If the driver turns the ignition switch to the ON position without wearing the seat belt, the seat belt warning light illuminates to alert the driver to wear the seat belt.

Headlight Automatic Shutdown Function

When the headlights or taillights are on, and the ignition switch is turned from ON to LOCK (OFF) or ACC position or the ignition key is removed, the headlights will be switched off in three minutes. If the driver's door is opened within that three-minute period, the headlights will be switched off automatically. This prevents the battery from discharging.

Turn Signal Light

When the ignition switch is turned to the ON position and turn-signal light switch is placed in the ON position for right or left turn-signaling, the system generates turn-signal light drive signals (flashing signals). The system also notifies of a blown turn-signal light bulb by shortening the flashing intervals of the corresponding indicator light.

Hazard Warning Light

The system detects a change from OFF to ON of the hazard warning input signal and activates or shuts off the hazard warning lights accordingly.

FOG LIGHT

The fog light switch becomes active only when the headlights are at the low-beam mode. Therefore, if the headlights are turned OFF, the fog lights will also be switched OFF. When the headlights are turned ON during the next key cycle, the fog lights will be OFF regardless of the fog light switch position.

DOME LIGHT

With the dome light switch in the "door controlled operation" (middle) position, the ETACS-ECU controls the dome light operation as follows

1. When a door is opened from inside or outside, (with the ignition switch turned to LOCK): When a door is opened, the ETACS-ECU causes the dome light to be illuminated at 100 percent intensity. When the door is closed, it dims the dome light to 65 percent intensity and approximately 30 seconds later, turns out the light completely. During this period (timer controlled period), the dome light goes out if the ignition switch is turned ON or the doors are locked.
2. When a door is opened or closed with the ignition switch in the ON position. The dome light illuminates at 100 percent intensity when a door is opened and turned out when it is closed.
3. When no door is opened and the ignition key is removed: The dome light is illuminated at 100 percent intensity and turned off approximately 30 seconds later. During that time (timer-controlled period), the dome light goes out if the ignition key is inserted and turned to ON or the door locking system is activated.
4. Dome light's answerback operation in response to door lock control by keyless entry system: To allow the driver to confirm the doors have locked by the keyless entry system, the ETACS-ECU causes the dome light to blink twice when the doors are locked by the RKE system and to illuminate for approximately 15 seconds when the doors are locked. The dome light's answerback operation in response to a keyless entry system control action is accompanied by flashing of the hazard warning lights.

INTERIOR LIGHT AUTOMATIC SHUTDOWN FUNCTION

This function prevents the battery from being discharged when the door is open or the dome light remains on with the ignition switch at the LOCK position. The ETACS-ECU turns on its KEEP relay to switch off battery power supply to the interior lights when the interior light loaded signal and all door switches remain on for approximately 30 minutes with the ignition switch at positions other than ACC. Then the interior lights will be switched OFF. If the ignition switch is turned ON again, the ETACS-ECU turns on its KEEP relay to illuminate the interior lights.

DOOR-AJAR INDICATOR LIGHT

This indicator light warns the driver that door(s) are not closed. If a door switch is on, the ETACS-ECU operates the door-ajar indicator light on the combination meter.

Panic Alarm Function

With the theft-alarm function armed, pressing the panic button on the keyless entry system transmitter causes the horn (theft-alarm horn and horn) to sound for about three minutes in an attempt to prevent theft. The alarm is turned off by pressing any switch on the transmitter.

CONFIGURATION FUNCTION

The keyless entry hazard answerback function can be adjusted by the special operation. Then they can be returned to the initial condition.

ECU CHECK FUNCTION

Note. The ECU CHECK function checks the communication status of each ECU. Displays of NG does not always mean ECU malfunction. If a malfunction is found by the ECU CHECK function, go to SYMPTOM TESTS .

1. Use the scan tool and the SWS monitor kit to check ECUs. Refer to MUT-II Reference Manual.
2. The following ECUs can be checked by using the scan tool and the SWS monitor kit. See «ECU CONDITION CHECK»(ref-168722-S16665764402004121700000) table.

ECU CONDITION CHECK

SERVICE DATA CHECK

1. Use the scan tool and the SWS monitor kit to check "Service Data." This "Service Data" check is applicable for signals, which are transmitted and received through the SWS communication line. For input signals, which are not compatible with the SWS monitor kit, refer to the «PULSE CHECK»(ref-168722-S20831381802004121300000) procedure (by using the scan tool or voltmeter).
2. The following input signals can be checked by using the scan tool and the SWS monitor kit. See «SERVICE DATA REFERENCE TABLES»(ref-168722-S29326860432004121700000) .

PULSE CHECK

The input signals (signals other than SWS communication line signals), which are compatible with the SWS monitor by using the scan tool or voltmeter, can be confirmed by the pulse check. Use the scan tool or voltmeter to check the input signals. See PULSE CHECK FUNCTIONS table. If a problem is found during the pulse check, proceed to appropriate symptom test. See SYMPTOM TESTS table.
