Code No.C1707: Implausible coding data

CAUTION

• If there is any problem in the CAN bus lines,

an incorrect diagnosis code may be set. Prior
to this diagnosis, diagnose the CAN bus lines
(Refer to GROUP 54C

− CAN Bus Diagnostics

Table ).

• Whenever ECU is replaced, ensure that the

CAN bus lines are normal.

• When diagnosis code No.C1707 is set in

ABS-ECU, the diagnosis code may also be set
in ETACS-ECU. When the diagnosis code is
set in ETACS-ECU, carry out the diagnosis of
the diagnosis code for ETACS-ECU first.

OPERATION

ABS-ECU receives the vehicle information stored in
the ETACS-ECU via CAN bus lines.

ETACS-ECU, this diagnosis code is set.

PROBABLE CAUSES

• Malfunction of ETACS-ECU

• ETACS-ECUs have been interchanged between

two vehicles.

• ABS-ECU malfunction

CAUTION

• If there is any problem in the CAN bus lines,

an incorrect diagnosis code may be set. Prior
to this diagnosis, diagnose the CAN bus lines
(Refer to GROUP 54C

− CAN Bus Diagnostics

Table ).

• Whenever ECU is replaced, ensure that the

CAN bus lines are normal.

OPERATION

CAUTION

• If there is any problem in the CAN bus lines,

an incorrect diagnosis code may be set. Prior
to this diagnosis, diagnose the CAN bus lines
(Refer to GROUP 54C

− CAN Bus Diagnostics

Table ).

• If diagnosis codes U0114 and U0141 are set in

ABS-ECU, always diagnose the CAN bus line.
If there is any fault in the CAN bus lines, an
incorrect diagnosis code may be set. In this
case, the set diagnosis code is not highly reli-
able.

• Whenever ECU is replaced, ensure that the

CAN bus lines are normal.

• When the ETACS-ECU of vehicles without

KOS is replaced, the encrypted code of the

ignition key needs to be registered to the
ETACS-ECU. (If the encrypted code is not reg-
istered, the engine cannot be started. Regis-
ter the encrypted code as described in
GROUP 54A, Immobilizer System

− How to

Register Key ID .)

DIAGNOSIS CODE SET CONDITIONS

This diagnosis code is set if ABS-ECU cannot
receive the signal sent from other ECU for a certain
period.

OPERATION

ABS-ECU communicates with the 4WD-ECU and
ETACS-ECU via the CAN bus lines.
