cautionBefore replacing the ECU, ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
 
 
 
 
PROBABLE CAUSES
  • Malfunction of the CAN bus lines
  • Malfunction of the central door locking system
  • Malfunction of the keyless operation key
  • Damaged wiring harness and connectors
  • Keyless operation key not registered
  • Malfunction of the KOS&OSS-ECU
  • Malfunction of the ETACS-ECU
  • Malfunction of the keyless operation antenna (Outer side)
  • Malfunction of the keyless operation antenna (Inner side)
  • Function setting error or no setting with a customisation
  • An ambient electric device or noise source interferes with this system when the lock/unlock switch is operated.
  • Malfunction of the door switches
  • A door is ajar.
  • The power supply mode is not OFF.
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE CAN bus diagnostics
Use M.U.T.-IIISE to diagnose the CAN bus lines.
Is the check result normal?
Go to Step 2.
Repair the CAN bus line (Refer to GROUP 54C - Troubleshooting ).
 
STEP 2. M.U.T.-IIISE diagnosis code
Check if any diagnosis code is set in the KOS&OSS-ECU.
Is the diagnosis code set?
Refer to diagnosis code chart .
Go to Step 3.
 
STEP 3. M.U.T.-IIISE other system diagnosis code
Check if any diagnosis code is set in the ETACS-ECU.
Is the diagnosis code set?
Perform troubleshooting for the ETACS (Refer to GROUP 54A - ETACS - Troubleshooting ).
Go to Step 4.
 
STEP 4. Check the central door locking system operation
Close all of the doors. Then the inside lock knob at the driver's door should function to lock and unlock all of the doors.
Is the check result normal?
Go to Step 5.
Perform troubleshooting for the central door locking system (Refer to GROUP 42A - Troubleshooting ).
 
STEP 5. Check the customisation
Check that KOS feature is set to Both enable or Door Entry enable with a customisation function.
Is it set to Both enable or Door Entry enable?
Go to Step 6.
Set KOS feature to Both enable or Door Entry enable with a customisation function (Refer to ).
 
STEP 6. M.U.T.-IIISE data list.
Check the ETACS-ECU service data relevant to the operation of keyless operation function.
  • Turn the power supply mode of the engine switch to "OFF".
  • Close the driver's door.
  • Close the front passenger's door.
  • Close the right side rear door.
  • Close the left side rear door.
  • Close the tailgate.

OK: Normal conditions are displayed for all the items.
Are the check result normal?
YES (Normal conditions are displayed for all the items.) : Go to Step 7.
NO (Normal condition is not displayed for item No. 81.) : Refer to GROUP 54A - ETACS, Inspection Procedure 5 "The front door switch (driver’s side) signal is not received ."
NO (Normal condition is not displayed for item No. 82.) : Refer to GROUP 54A - ETACS, Inspection Procedure 6 "The front door switch (passenger’s side) signal is not received. ."
NO (Normal condition is not displayed for item No. 83.) : Refer to GROUP 54A - ETACS, Inspection Procedure 7 "The rear door switch (RH) signals is not received ."
NO (Normal condition is not displayed for item No. 84.) : Refer to GROUP 54A - ETACS, Inspection Procedure 8 "The rear door switch (LH) signals is not received ."
NO (Normal condition is not displayed for item No. 88.) : Refer to GROUP 54A - ETACS, Inspection Procedure 4: "The front door lock actuator (driver’s side) signal is not received ."
 
STEP 7. Keyless operation system communication test
Using M.U.T.-IIISE, perform the antenna communication test to check that the keyless operation antenna (Outer side) communicates normally (Refer to ).
  • PS side antenna(outdoor)
  • DR side antenna(outdoor)
  • Tailgate antenna(outdoor)
OK: Normal values are displayed for all the items
Is the check result normal?
Go to Step 9.
Go to Step 8.
 
STEP 8. Check with another registered keyless operation key.
Using another registered keyless operation key, check whether the doors can be locked and unlocked for twice or more consecutively.
Can they be operated?
You can change the power supply mode or you do not have the other keyless operation keys that is registered to your vehicle. : Go to Step 10.
They cannot be operated. : Go to Step 9.
 
STEP 9. Check of the troubles
Remove commercial electric appliances if they are attached on. Operate the lock/unlock switch to check that the door can be locked and unlocked.
Is the check result normal?
The diagnosis is complete.
Replace KOS&OSS-ECU and register the ID codes (Refer to ).
 
STEP 10. Keyless operation key battery charged level check
Check whether the LED illuminates when the lock/unlock switch on the keyless operation key that does not work is pressed.
Is the check result normal?
Go to Step 11.
Replace the battery in the keyless operation key (Refer to ).
 
STEP 11. Keyless operation key check
Check whether the registered keyless operation key is used.
Is the registered keyless operation key used?
Used. : Register the key ID and keyless operation key ID of the keyless operation key. Then go to Step 12.
Not used (The keyless operation key is not registered or the keyless operation key is also used for another vehicle). : Refer to the key ID registration procedure manual to register the key ID. If the key ID cannot be registered, replace the keyless operation key and register the key ID.
 
STEP 12. Check of the trouble
Operate the lock/unlock switch to check that the door can be locked and unlocked.
Is the check result normal?
The diagnosis is complete.
Replace the keyless operation key, and register the ID codes (Refer to ).
