TAILGATE <VEHICLES WITH ELECTRIC TAILGATE>

BODY

42A-88

Code No.U1000: OSS CAN Time-out

CAUTION

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

diagnose the CAN bus line.

• When replacing the ECU, always check that 

the communication circuit is normal.

DIAGNOSTIC FUNCTION

If the signal from OSS-ECU cannot be received, the 
electric tailgate control unit sets diagnosis code No. 
U1000.

JUDGMENT CRITERIA

With the statuses that the ignition switch is at ON 
position, system voltage is 10 to 16 V (data from 
ETACS-ECU), and there is no malfunction to the 
power supply fuse, or odometer value is 80.5 km or 
more, if the communication with OSS-ECU cannot 
be established for 2,500 ms or more, the electric tail-
gate control unit determines that a problem has 
occurred.

PROBABLE CAUSES

• Malfunction of OSS-ECU

• Malfunction of the electric tailgate control unit

• Malfunction of CAN bus line

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III CAN bus diagnostics
Use M.U.T.-III to diagnose the CAN bus lines.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Repair the CAN bus lines. (Refer to GROUP 
54C 

− Troubleshooting .)

STEP 2. M.U.T.-III diagnosis code for other 
systems
Check that OSS-ECU sets a diagnosis code.

Q: Is the diagnosis code set?

YES : 

Diagnose the OSS-ECU. (Refer to GROUP 

42B 

− Diagnosis Code Chart .)

NO : 

Go to Step 3.

STEP 3. M.U.T.-III other system diagnosis code
Check if the diagnosis code No. U1000 is set to the 
KOS-ECU, SRS-ECU, combination meter, 
ETACS-ECU, MMCS, radio and CD player or 
A/C-ECU.

Q: Is the diagnosis code set?

YES : 

Go to Step 4.

NO : 

Go to Step 5.

STEP 4. Check whether the diagnosis code is 
reset.
Check again if the electric tailgate control unit sets a 
diagnosis code.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from "LOCK" (OFF) 

position to "ON" position.

(3) Check if diagnosis code is set.

Q: Is the diagnosis code set?

YES : 

Replace the OSS-ECU.

NO : 

An intermittent malfunction may be present. 
(Refer to GROUP 00 

− How to Use 

Troubleshooting/Inspection Service Points - 
How to Cope with Intermittent Malfunction .)

STEP 5. Check whether the diagnosis code is 
reset.
Check again if the electric tailgate control unit sets a 
diagnosis code.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from the LOCK (OFF) 

position to the ON position.

(3) Check if the diagnosis code is set.

Q: Is the diagnosis code set?

YES : 

Replace the electric tailgate control unit.

NO : 

An intermittent malfunction may be present. 
(Refer to GROUP 00 

− How to Use 

Troubleshooting/Inspection Service Points - 
How to Cope with Intermittent Malfunction .)

TAILGATE <VEHICLES WITH ELECTRIC TAILGATE>

BODY

42A-89

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 

.)

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 electric 
tailgate control unit 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

STEP 1. M.U.T.-III CAN bus diagnostics
Use the M.U.T.-III to diagnose the CAN bus lines.

Q: Is the check result normal?

YES : 

Go to Step 2

NO : 

Repair the CAN bus line (Refer to GROUP 
54C 

− Troubleshooting ). On completion, go 

to Step 3.

STEP 2. Check whether the diagnosis code is 
reset.
Check again if the diagnosis code is set to the elec-
tric tailgate control unit.
(1) Erase the diagnosis code.
(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?

YES : 

Replace the ETACS-ECU. Then go to Step 

3.

NO : 

The procedure is complete.

STEP 3. Check whether the diagnosis code is 
reset.
Recheck if the diagnosis code is set to the electric 
tailgate control unit.
(1) Erase the diagnosis code.
(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?

YES : 

Return to Step 1.

NO : 

The procedure is complete.

Code No.U1195 Coding not completed

CAUTION

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

nose the CAN bus lines.

• Before replacing the electric tailgate control 

unit, ensure that the power supply circuit, the 
earth circuit and the communication circuit 
are normal.

DIAGNOSTIC FUNCTION

If the vehicle information data is not registered to the 
electric tailgate control unit, the electric tailgate con-
trol unit 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 electric tailgate control unit determines that a 
problem has occurred.

PROBABLE CAUSES

• Malfunction of CAN bus line

• Malfunction of electric tailgate control unit

• Malfunction of the ETACS-ECU
