SEAT BELT WITH PRE-TENSIONER
Caution:
1. Wait for at least 60 seconds after
disconnecting the negative ( - ) terminal of
the battery before starting any operation.The
removed negative ( - ) terminal must be
protected by wrapping the tape. (Refer to
P.52B-3.)
2. Never disassemble or repair the seat belt
with pre-tensioner. Replace the part with a
new one when it malfunctions.
3. Take an extra care to deal with the seat belt
with pre-tensioner by avoiding dropping or
wetting it with water or oil. If any dent, crack,
or deformation is found, be sure to replace
the seat belt with pre-tensioner with a new
part.4. Do not place a heavy object on top of the
seat belt pre-tensioner.
5. Never keep the seat belt with pre-tensioner
in a place where the temperature can exceed
over 90_C.
6. Replace the seat belt with pre-tensioner with
a new one after operating the seat belt
pre-tensioner.
7. Wear gloves or protective glasses when
handling the seat belt with pre-tensioner
after operation.
8. If the seat belt with pre-tensioner before
operation needs to be discarded, be sure
to do so after operating the seat belt
pre-tensioner. (Refer to P.52B-64.)

ON-VEHICLE SERVICE
SPEEDOMETER CHECK
(1) Ensure that tire pressure indicates the value of tirepressure label.
(2) Place the vehicle on speedometer teste r.
(3)
(4) For prevention of front wheel lateral runout, install
extension fittings on front towing eye and tie down hook,
and install both ends on anchor plate.
(5) For prevention of vehicle from starting out, install chain or wire (the other end of which is tightly fixed on rear
towing eye) on the vehicle.
(6) Ensure that speedometer indication range is within standard value, or pointer deflection is within limit value.
Caution
During operation, avoid excessive acceleration and
deceleration.

DIAGNOSIS CODE INSPECTION PROCEDURES
Code No. 11 ETACS-ECU-related failureProbable cause
The ETACS-ECU monitors its own communication data, outputting this diagnosis
code when data error occurs 15 consecutive times (for 0.6 seconds). The
diagnosis code output stops when the ETACS-ECU confirms that its data was
transmitted normally 15 consecutive times (for 0.6 seconds).DETACS-ECU fault
Replace ETACS-ECU.
Code No. 12 Column switch-related fault or fault in
connecting to ETACS-ECUProbable cause
This diagnosis code is output when a column switch outputs a signal (at least
three times a second) that is not in accordance with the transmission request
signal from ETACS-ECU. The diagnosis code output stops when the column
switch continuously outputs for one second a signal that accords with the
transmission request signal from ETACS-ECU.DColumn switch fault
