Code No.U1000 OSS CAN timeout

CAUTION

• If the diagnosis code No. U1000 is set, be sure

to diagnose the CAN bus line.

• Before replacing the ECU or combination

meter, ensure that the power supply circuit,
the earth circuit and the communication cir-
cuit are normal.

DIAGNOSTIC FUNCTION

If the signal from OSS-ECU cannot be received, the

combination meter sets the diagnosis code No.
U1000.

JUDGEMENT CRITERIA

With the ignition switch is at ON position, the diagno-
sis code No. U1190 is not stored and the diagnosis
code No. U1195 is not stored, if the communication
with OSS-ECU cannot be established for 2500 ms or
more, the combination meter determines that a prob-
lem has occurred.

Code No.U1005 Corner/Back SNS.ECU CAN timeout

CAUTION

• If the diagnosis code No. U1005 is set, be sure

to diagnose the CAN bus line.

• Before replacing the ECU or combination

meter, ensure that the power supply circuit,
the earth circuit and the communication cir-
cuit 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
Immobilizer System

− How to Register Key ID

P.54A-33

.)

TROUBLE JUDGEMENT

If signal from the corner sensor/back sensor-ECU
cannot be received for 500 milliseconds or more, the
ETACS-ECU sets diagnosis code No. U1005.

sor-ECU

• Malfunction of the ETACS-ECU

• Malfunction of the CAN bus

DIAGNOSIS PROCEDURE

Code No.U1190 No receive fault detect signal

CAUTION

• Before replacing the ECU, ensure that the

power supply circuit, the earth circuit and the
communication circuit 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
Immobilizer System

− How to Register Key ID

P.54A-33

.)

JUDGEMENT CRITERIA

ETACS-ECU sends the diagnosis code (U code)
detection permission or prohibition signal to each
ECU connected to the CAN bus line. If the combina-
tion meter cannot receive the diagnosis code (U
code) detection permission or prohibition signal for 5
seconds after turning the electric motor switch to ON
position, diagnosis code U1190 will be set.

PROBABLE CAUSES

• Malfunction of the ETACS-ECU

• Malfunction of CAN bus line

DIAGNOSIS PROCEDURE

(2) Turn the ignition motor switch from "LOCK" (OFF)

position to "ON" position.

(3) On completion, check that the diagnosis code is

reset.

Q: Is the diagnosis code set?

Code No.U1195 Coding not completed

CAUTION

• If the diagnosis code No. U1195 is set, diag-

nose the CAN bus lines.

• Before replacing the combination meter,

ensure that the power supply circuit, the earth
circuit and the communication circuit are nor-
mal.

DIAGNOSTIC FUNCTION

If the vehicle information data is not registered to the
combination meter, the combination meter sets the
diagnosis code No. U1195.

JUDGMENT CRITERIA

With the global coding counter value "0," if all the glo-
bal coding data (vehicle information) are not stored,
the combination meter determines that a problem
has occurred.
