ENABLING/DISABLING THE ANSWERBACK FUNCTION
If the keyless entry system locks or unlocks the doors, the dome light flashes or illuminates, the hazard warning light flashes (hazard answerback function) and the horn sounds (horn answerback function). The hazard and horn answerback functions can be enabled or disabled according ENABLING/DISABLING THE HAZARD ANSWERBACK FUNCTION .
ENABLING/DISABLING THE HAZARD ANSWERBACK FUNCTION
The hazard answerback function can be enabled or disabled by one of the 2 following procedures
Scheme 17
- Enter the hazard answerback customize mode by observing one of the following steps. If the ETACS-ECU enters the customize mode, its tone alarm will sound once. Turn the ignition switch to LOCK (OFF) position. Turn off the hazard warning light switch. Connect Scan Tool MB991502 to the data link connector terminal No. 1. Close the driver's side door. Leave the windshield washer switch on for at least 10 seconds. Then the ETACS-ECU tone alarm will sound once.
- If the transmitter LOCK switch is pushed consecutively twice (within 2 seconds), the ETACS-ECU tone alarm will sound, indicating that the hazard answerback function can be enabled or disabled when the doors are locked. Enable the hazard answerback function when the doors are locked: The ETACS-ECU tone alarm will sound once. Disable the hazard answerback function when the doors are locked: The ETACS-ECU tone alarm will sound twice.
- If the transmitter UNLOCK switch is pushed consecutively twice (within 2 seconds), the ETACS-ECU tone alarm will sound, indicating that the hazard answerback function can be enabled or disabled when the doors are unlocked. Enable the hazard answerback function when the doors are locked: The ETACS-ECU tone alarm will sound once. Disable the hazard answerback function when the doors are locked: The ETACS-ECU tone alarm will sound twice.
- Exit the hazard answerback customize mode by observing one of the following steps: Disconnect Scan Tool MB991502 from the data link connector, or disconnect data link connector terminal No. 1 from the ground. Turn the ignition switch to position other than LOCK (OFF), or remove the ignition key. Open the driver's side door. NOTE: If any operation is not done for at least 3 minutes after the ETACS-ECU has entered the customize mode, the hazard answerback customize mode will be canceled automatically. Any other warning tone alarm output occurs.
When Only The Transmitter Is Used
- Remove the ignition key.
- Push the LOCK switch while holding the UNLOCK switch pushed for 4-10 seconds.
- If the LOCK switch and UNLOCK switch are released in that order, the ETACS-ECU tone alarm will sound, indicating that the hazard answerback function can be enabled or disabled when the doors are locked. Enable the hazard answerback function when the doors are locked: The ETACS-ECU tone alarm will sound once. Disable the hazard answerback function when the doors are locked: The ETACS-ECU tone alarm will sound twice.
- If the UNLOCK switch and LOCK switch are released in that order, the ETACS-ECU tone alarm will sound, indicating that the hazard answerback function can be enabled or disabled when the doors are unlocked. Enable the hazard answerback function when the doors are locked: The ETACS-ECU tone alarm will sound once. Disable the hazard answerback function when the doors are locked: The ETACS-ECU tone alarm will sound twice.
ENABLING/DISABLING THE HORN ANSWERBACK FUNCTION
- Remove the ignition key.
- Push the UNLOCK switch while holding the LOCK switch pushed for 4-10 seconds.
- If the LOCK switch and UNLOCK switch are released at the same time, the ETACS-ECU tone alarm will sound, indicating that the horn answerback function can be enabled or disabled. Enable the horn answerback function when the doors are locked: The ETACS-ECU tone alarm will sound once. Disable the horn answerback function when the doors are locked: The ETACS-ECU tone alarm will sound twice.
- If the LOCK switch and UNLOCK switch are released at the same time, the ETACS-ECU tone alarm will sound, indicating that the horn answerback function can be enabled or disabled. NOTE: The horn will sound if the doors are locked with the keyless entry system. Enable the horn answerback function: The ETACS-ECU tone alarm will sound once. Disable the horn answerback function: The ETACS-ECU tone alarm will sound twice. NOTE: The horns sound when the other doors are locked by the keyless entry system with some door(s) has been locked. Enable the horn answerback function: The ETACS-ECU tone alarm will sound 3 times.
HOW TO REGISTER SECRET CODE
Each individual secret code is registered inside the transmitter, and so it is necessary to register these codes with the EEPROM inside the receiver in the following cases
- When the transmitter or ETACS-ECU is replaced.
- If more transmitters are to be used.
- If it appears that a problem is occurring because of faulty registration of a code.
A maximum of 4 different codes can be stored in the EEPROM memory (4 different transmitters can be used). When the code for the first transmitter is registered, the previously registered codes for all transmitters are cleared. Therefore, if you are using 4 transmitters or adding more transmitters, the codes for all transmitters must be registered at the same time.
- Check that the doors lock normally when the key is used.
- Insert the ignition key.
- Connect the scan tool to the data link connector. If the scan tool is not used, ground terminal No. 1 of the data link connector.
- Press the hazard switch 6 times within 10 seconds.
- Press the transmitter switch, and then press it 2 times within 10 seconds of the first press. This will register the code.
- When registration is completed, the code registration monitor request is output (all doors locked and unlocked).
- If you are using 2 or more transmitters or have added a second transmitter, the same registration procedure should be carried out within one minute after registering the code for the first transmitter. After the second registration is completed, the code registration monitor request is output (all doors locked and unlocked).
- Registration mode will be canceled under the following conditions: When the secret code for 4 transmitters has been registered. When one minute has been passed after registration mode started. When scan tool MB991502 is disconnected (the ground connection is broken). When the key is removed from the key cylinder.
- After the registration is completed, carry out the following work, and then check that the keyless entry system operates normally. Remove the ignition key. Close all of the doors.
