FUNCTION <Vehicles with keyless entry system>

M1549002500270

Required Special Tools:

• MB991223: Harness Set

• MB991502: Scan Toll (MUT-II)

• MB991529: Diagnostic Trouble Code Check Harness

The following functions can be enabled or disabled by operat-
ing input switches in a special manner. This set mode is stored 
after the battery is disconnected.

• Keyless entry hazard answerback function

• Headlight automatic shutdown function

• Initialization of above mentioned functions

NOTE: The keyless entry hazard answerback can be also 
adjusted by operating the RKE transmitter. (however, this 
adjustment can be done more easily by operating the transmit-
ter.) Refer to GROUP 42, Keyless Entry System, On-vehicle 
Service, Enabling/disabling the Answerback Function 

P.42-55

.

Entry conditions for adjustment mode

1. Set switches to the following conditions:

• Hazard warning light switch: OFF

• Diagnosis control: ON (Connect scan tool MB991502 to the 

data link connector, or connect the data link connector ter-
minal 1 to ground.)

• Key reminder switch: OFF (insert the ignition key)

• Ignition switch: "LOCK" (OFF)

• Driver's door switch: OFF (driver's door closed)

2. If the windshield washer switch remains on for 10 seconds 

or more, the tone alarm incorporated in the ETACS-ECU 
sounds once, and then enter the adjustment mode.

Release condtions for the adjustment mode

The adjustment mode will be released under one of the follow-
ing conditions:

• Diagnosis control: ON (Disconnect scan tool MB991502 

from the data link connector, or disconnect the data link 
connector terminal 1 from ground.)

• Key reminder switch: ON (ignition key removed)

• Ignition switch: Turn to the positions other than "LOCK" 

(OFF).

• Driver's door switch: ON (driver's door opened)

• After three minutes while the adjustment is not made (If any 

adjustment has been made within the three-minute period, 
cancel or complete the operation, and then release the 
adjustment mode within three minutes).

• When any other warning tone alarms sound

Configuration of Functions

ITEM

ADJUSTMENT PROCEDURE

Keyless entry hazard 
answerback

If the transmitter "LOCK" switch is turned on twice within two seconds, the lock 
answerback function is enabled or disabled.

• If the function is enabled, the tone alarm sounds once. (initial status)

• If the function is disabled, the tone alarm sounds twice.

If the transmitter "UNLOCK" switch is turned on twice within two seconds, the 
unlock answerback function is enabled or disabled.

• If the function is enabled, the tone alarm sounds once. (initial status)

• If the function is disabled, the tone alarm sounds twice.

Vehicle speed-
dependent wiper 
function

 The vehicle speed-dependent wiper function is enabled or disabled by turning on 
the windshield wiper mist switch for two seconds or more.

•  Enabled: the tone alarm sounds once. (initial status)

•  Disabled: the tone alarm sounds twice.

Headlight automatic 
shutdown function

If the passing switch is turned ON for more than two seconds with the headlight 
switch turned to ON and the turn signal light switch (RH) turned ON, the headlight 
automatic shutdown function is switched in the following order: (Next to "c," the 
function returns to "a" and repeats the sequence from "a".)

a. With the ignition switch in "LOCK" (OFF) position, the automatic shutdown 

function is enabled when the lighting switch is turned ON and the tone alarm 
sounds once.

b. If the function is disabled, the tone alarm sounds twice.
c. When the function is enabled (While the ignition switch is at "LOCK" (OFF) 

position, the automatic shutdown function is enabled when the lighting switch is 
turned ON.), the tone alarm sounds three times. (initial status)

The delay-off time of 
the dome light

When the turn-signal light switch is moved in the order of LH 

→ RH → LH → RH → 

LH, the dome light delay-off time will be changed as follows. (Next to "e," the 
function returns to "a" and repeats the sequence from "a".)
a. 30 seconds: the tone alarm sounds once.
b. 10 seconds: the tone alarm sounds twice.
c. 0 second (no delay-off time): the tone alarm sounds three times.
d. 15 seconds: the tone alarm sounds four times. (initial status)
e. 7.5 seconds: the tone alarm sounds five times.

Initialization of above 
mentioned functions

If the windshield washer switch is turned ON for more than 20 seconds, the tone 
alarm sounds twice and all functions are initialized. (The configuration mode entry 
tone alarm sounds after 10 seconds, but the switch must kept ON for 20 seconds 
to achieve initialization.)
If the windshield washer switch is kept ON for more than 20 seconds without prior 
entry of the configuration mode, the configuration mode is entered after 10 
seconds and initialization does not take place.
