ETACS-Ecu Function Adjustment Procedure

The following functions can be adjusted by operating input swatches. The adjustments will be stored in the ECU memory even after a battery cable is disconnected:

Switching of keyless entry answerback function. (From activation to deactivation, or vice versa)
Initialization the above function (From deactivation to activation)

Entry conditions the adjustment mode
The ETACS-ECU sounds a tone alarm once when all of the following conditions are satisfied, and then enters the adjustment mode:
- Data link control: "ON" [Connect scan tool MB991958 (MUT-III sub assembly) or ground the data link connector No. 1 terminal.]
- Key reminder switch: "OFF"
- Ignition switch: "OFF"
- Door switch: "OFF" (Close the door.)
- If all of the conditions above are satisfied, the taillight switch will be turned on for more than 10 seconds.
Exit conditions from the adjustment mode
The ETACS-ECU cancels the adjustment mode

when any of the following conditions is satisfied:
- Diagnosis control: "OFF" [Disconnect scan tool MB991958 (MUT-III sub assembly) or disconnect the data link connector No. 1 terminal from the ground.]
- Key reminder switch: "ON" (Pull out the ignition key.)
- Ignition switch: Other than "OFF"
- Door switch: "ON" (Open the door.)
- After the ETACS-ECU has entered the adjustment mode, no adjustment is made within 3 minutes (If any adjustment is made within 3 minutes, the ETACS-ECU monitors a adjustment operation for other 3 minutes.)
- Other warning tone alarm sounds

Adjustment of functions

FUNCTION AND ADJUSTMENT PROCEDURE

FUNCTION	ADJUSTMENT PROCEDURE
Keyless entry answerback function	When the transmitter lock switch is turned on twice continuously within 2 seconds, the lock answerback function toggles on and off. If the function toggles on, the tone alarm sounds once (default condition). If the function toggles off, the tone alarm sounds twice. When the transmitter unlock switch is turned on twice continuously within 2 seconds, the unlock answerback function toggles on and off. If the function toggles on, the tone alarm sounds once (default condition). If the function toggles off, the tone alarm sounds twice.
Initialization of all the ETACS-ECU functions (From deactivation to activation)	When the taillight switch remains on for more than 20 seconds, the tone alarm sounds twice and then the keyless entry system answerback. The tone alarm will sound in 10 seconds (indicating that the ETACS-ECU enters the adjustment mode), but the washer switch must remains off for 20 seconds in order to initialize all the functions. If the taillight switch remains on for more than 20 seconds without entering the adjustment mode, the system enters the adjustment mode in 10 seconds, but does not initialize all of the functions.

If the function toggles on, the tone alarm sounds once (default condition).
If the function toggles off, the tone alarm sounds twice.

Initialization of all the ETACS-ECU functions (From deactivation to activation)

When the taillight switch remains on for more than 20 seconds, the tone alarm sounds twice and then the keyless entry system answerback.
The tone alarm will sound in 10 seconds (indicating that the ETACS-ECU enters the adjustment mode), but the washer switch must remains off for 20 seconds in order to initialize all the functions. If the taillight switch remains on for more than 20 seconds without entering the adjustment mode, the system enters the adjustment mode in 10 seconds, but does not initialize all of the functions.
