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

Code No. 13 Front-ECU-related fault or fault in
connecting to ETACS-ECUProbable cause
This diagnosis code is output when the signal output from the front-ECU to
ETACS-ECU contains an error for 15 consecutive communication cycles (0.6
seconds). The diagnosis code output stops when the signal output from the
front-ECU to ETACS-ECU is normal for 15 consecutive communication cycles

Code No. 21 Short circuit in communication lines.Probable cause
This diagnostic code is output when the voltage on an SWS communication line
goes LOW for 0.3 seconds. The diagnosis code output stops when the
ETACS-ECU data line voltage goes HIGH for 0.3 seconds, or when the
ETACS-ECU receives a normal signal from another ECU or switch. During the
