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 the MUT-II>)
•
Key reminder switch: ON (Pull out the ignition key.)
•
Ignition switch: Other than LOCK (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 an adjustment operation for
other 3 minutes.
•
Other warning buzzer(s) sounds

Adjustment of functions
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 buzzer sounds once (default con-
dition).
•
If the function toggles off, the buzzer 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 buzzer sounds once (default con-
dition).
•
If the function toggles off, the buzzer sounds twice,
Initialisation of all the ETACS func-
tions (From deactivation to activa-
tion)When the tailgate switch remains on for more than 20 seconds, th
buzzer sounds twice and he answer-back function of the keyless
entry system is initialised.
The buzzer will sound in 10 seconds (indicating that the ETACS-
ECU enters the adjustment mode), but the washer switch must re-
mains off for 20 seconds in order to initialise all the functions.
If the tailgate 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 initialise all of the functions.

Refer to GROUP 00 – How to Use Troubleshooting/Inspection Service Points.
NOTES WITH REGARD TO DIAGNOSIS
The phenomena listed in the following table are not abnormal.
Phenomenon Explanation of phenomenon
System check sound When starting the engine, a thudding sound can sometimes
be heard coming from inside the engine compartment, but
this is because the system operation check is being
performed, and is not an abnormality.
ABS operation sound Sound of the motor inside the ABS hydraulic unit operation.
(whine)
Sound is the generated along with vibration of the brak
pedal. (Scraping).
When ABS operates, sound is generated from the vehicle
chassis due to repeated brake application and release.
(Thump: suspension; squeak: tyres)
ABS operation (Long braking distance) For road surfaces such as snow-covered roads and gravel
roads, the braking distance for vehicles with ABS can
sometimes be longer than that for other vehicles.
Accordingly, advise the customer to drive safely on suc
roads by lowering the vehicle speed and not being too
overconfident.
Diagnosis detection condition can vary depending on the diagnosis code.
Make sure that checking requirements listed in the “Comment” are satisfied when checking the trouble
symptom again.
DIAGNOSIS FUNCTION 35201120106
DIAGNOSIS CODES CHECK
Read a diagnosis code by the MUT-II or ABS
warning lamp. (Refer to GROUP 00 – How to Use
Troubleshooting/Inspection Service Points.)
ERASING DIAGNOSIS CODES

Remedy the malfunctions indicated by th
diagnosis codes, disconnect the diagnosis code
check harness, and then install the valve relay.
Then turn the ignition switch to ON again t
check the ABS warning lamp. (Refer to P.35-36-
16.) If the lamp indicates a malfunction, th
valve relay system may be detective. (Refer to
P.35-36-14.)
ERASING DIAGNOSIS CODES
Connect the MUT-II to the diagnosis connector (16-
pin), and then erase the diagnosis codes.
Without the MUT-II
Remove the battery cable from the battery (-)
terminal for 10 seconds or more, and the
reconnect the cable.

Remedy the malfunctions indicated by th
diagnosis codes, disconnect the diagnosis code

relay harness. Then turn the ignition switch to ON
again to check the ABS warning lamp. (Refer to
P.35B-19.) If the lamp indicates a malfunction,
the valve relay system may be defective. (Refer
to P.35B-17)
ERASING DIAGNOSTIC CODES
Connect the MUT-II to the diagnosis connector (16-

ERASING DIAGNOSIS CODES
With the MUT-II
Refer to GROUP 00 – How to Use
Troubleshooting/Inspection Service Points
When diagnostic trouble codes (Nos. 21 to 24) (for vehicle wheel speed sensor system failures) occur,
normal MUT-II operation may not erase those codes. In that case, erase the diagnostic trouble codes
using the following procedures.
1.
Perform erasing of the diagnostic trouble codes by special operation of the brake pedal. (See erasing
procedure for the diagnostic trouble codes without use of the MUT-II.)
2.
Turn the ignition switch OFF.
3.
Perform erasing of the diagnostic trouble codes by use of the MUT-II.
