Toyota Sienna Service Manual: Registration
1. DESCRIPTION OF CODE REGISTRATION
HINT:
The key has 2 codes: The key code (immobiliser code)
and the wireless code. Both of these codes need to be
registered. Refer to page for the wireless code
registration procedures.
- When adding master keys or sub keys (Additional
registration):
- Register key code (immobiliser code) in the
transponder key ECU.
- When replacing the transponder key ECU (New
registration):
- Register the key code (immobiliser code) in the
transponder key ECU.
- Register the ECU COMMUNICATION ID
between the ECM and the transponder key
ECU.
- When replacing the ECM:
- Register the ECU COMMUNICATION ID
between the ECM and the transponder key
ECU.
2. KEY REGISTRATION
- Automatic registration (Procedure "B")
The new registration of the key codes (immobiliser
codes) is made automatically.
HINT:
- When installing a new transponder key ECU, the
key codes (immobiliser codes) must be
registered.
- A new transponder key ECU starts in the
automatic key code registration mode. In this
mode, a maximum of 4 key codes for 3 master
keys and 1 sub key can be registered. Since the
transponder key ECU can distinguish types of
keys, any registration order is acceptable.
Automatic Key Code Registration (New Registration)
HINT:
- When no key is inserted in the key cylinder while
the system is in automatic key code registration
mode, the security indicator remains on.
- When the immobiliser system is operating
normally and the key is pulled out, the security
indicator blinks continuously.
- If the key code registration has failed in the
automatic key code registration mode, code 2-1
will be output from the security indicator. Trying
to register an already registered key will cause
code 2-2 to be output when the key is inserted. If
the number of registered key codes exceeds the
limit, code 2-3 will be output from the security
indicator. The output details are shown below.
- Finish the automatic key code registration mode.
The automatic key code registration mode can be
forced to end, when at least 1 key code (immobiliser
code) for the master key has been registered.
- Turn the ignition switch on and off 5 times
within 10 seconds using the already registered
master key.
3. REGISTRATION OF ADDITIONAL KEY
- Additional registration (Procedure "A")
Register an additional key by using the intelligent
tester.
HINT:
- A maximum of 5 key codes and 3 sub key codes
can be registered.
- Registration mode will end if any step is not
completed within the specified time.
- When the ignition cylinder or the key cylinder set
is replaced, remove the transmitter module from
the original master key. Then install this
transmitter module to a new key and use it as
master key. If necessary, use this master key to
register other keys.
NOTICE:
When only the ignition key cylinder has been
replaced, you can lock or unlock doors by
wireless operation using the new key with built
in transmitter but not by inserting it in the door
key cylinder. Therefore, keep the original key for
door lock or unlock operation in order to avoid
malfunctions caused by a dead transmitter
battery in the new key.
Additional Registration
NOTICE:
If the key code registration has failed in
automatic key code registration mode, code 2-1
will be output from the security indicator. Trying
to register an already registered key will cause
code 2-2 to be output when the key is inserted. If
the number of registered key codes exceeds the
limit, code 2-3 will be output from the security
indicator. The output details are shown in
procedure "B".
HINT:
- A brief outline of procedures for key code
registration is shown above. For detailed
information, please refer to the screen of the
intelligent tester.
- When the immobiliser system is operating
normally and the key is pulled out, the security
indicator will blink.
4. ERASURE OF KEY CODE
- Erase key codes by using the intelligent tester.
HINT:
- All key codes will be erased except for the
master-key which is used for erasing the key
codes. In order to use a key for which the code
has been erased, it is necessary to register the
key code again.
- The registration operation will be cancelled if any
step is not completed within the specified time.
Erasing Key Code
HINT:
- A brief outline of procedures for key code
registration is shown above. For detailed
information, please refer to the screen of the
intelligent tester.
- When the immobiliser system is operating
normally and the key is pulled out, the security
indicator will blink
5. ECU COMMUNICATION ID REGISTRATION
NOTICE:
- The ECU communication ID should be registered
when the transponder key ECU and/or the ECM is
replaced in order to match it to the ECM
COMMUNICATION ID.
- The SFI system cannot be started unless the ECM
COMMUNICATION ID matches.
- ECU communication ID registration (Procedure "C")
Register the ECU COMMUNICATION ID, after the
transponder key ECU and/or the ECM is replaced
turn the ignition switch on.
- Using SST, connect terminals TC and CG of
the DLC3.
SST 09843-18040
- Turn the ignition on and leave it as is for 30
minutes.
- Check that the engine starts.
HINT:
Use this procedure to troubleshoot the engine immobiliser
system.
The intelligent tester should be used in steps 4, 5 and 7.
