1. Transponder Key Type
Before any Immobilizer functions are performed, verify the type of transponder key
that you are attempting to use for the service operation. Some functions may only be
performed with a registered Master Key.
2. Transponder Code Registration
This function allows the registration of additional transponder keys (Master or Sub)
using a registered Master Key.
3. Transponder Code Erasure
This function allows the user to erase all the transponder keys except the registered
Master Key used during this function.
4. Transponder ECU Reset
This function allows the registration of a new Master Key even if all original Master
Keys are lost. Once the Immobilizer system is reset, all previous registered keys will
be erased.
5. Transponder ECU Replacement
When the Transponder ECU is replaced, the transponder keys must be registered to
the new ECU, auto registration closed, and ECU communication completed.
6. Engine ECU Replacement
When the Engine ECU is replaced, ECU communication must be completed to
synchronize an encrypted security code between the engine and Transponder ECUs.Function

1. Transponder Key Type
Before any Immobilizer functions are performed, verify the type of transponder key
that you are attempting to use for the service operation. Some functions may only be
performed with a registered Master Key.
A. Insert the current key into the ignition cylinder and turn to the ON position.
HINT:
The Immobilizer key blanks are preconfigured as Master or Sub Keys. Master Key
blanks cannot be registered as Sub Keys nor can Sub Key blanks be registered as
Master Keys. Also, the flat key is now enabled as a full function Master Key that must
be registered.
B. Follow the screen flow in Figure 1 to determine the key type.
C. Key type and registration status will be indicated on the Immobilizer data list
(Figure 1, screen E).
ªMATCHº = The key in the ignition cylinder matches this key type.
ªNOMATCHº = The key in the ignition cylinder does NOT match this key type.

D. Verify that keys are registered correctly by starting the engine with each newly
registered key.
NOTE:
If the vehicle starts, the new key code was registered correctly.
If the vehicle does not start with any key, perform the Immobilizer Reset function
again.
If only one of the registered keys will not start the vehicle, attempt to register the
key again following the Transponder Code Registration procedure (page 5 of
this bulletin).
5. Transponder ECU Replacement
When the Transponder ECU is replaced, the transponder keys must be registered,
auto registration closed, and ECU communication completed.
A. Replacement transponder ECUs are in auto registration mode. This allows
transponder keys to automatically register as they are inserted into the ignition
cylinder. It is possible to automatically register 3 Master Keys, and 1 Sub Key.
NOTE:
If 4 keys are registered at this time, auto registration mode is closed.
If less than 4 keys are registered at this time, auto registration mode must be closed
manually by cycling the ignition ON/OFF more than 5 times in 10 seconds.
If more than 4 keys need to be registered, use Transponder Code Registration
procedure (page 5 of this bulletin).
B. Once auto registration mode is closed, ECU Communication must be performed
between the transponder ECU and the Engine ECU. Complete ECU
communication using the following steps:
a. Insert registered Master Key into the ignition cylinder.
b. Turn ignition ON (engine OFF).
c. Short Tc and CG terminals of DLC3 using Diagnosis Check Wire
(SST 09843±18040 or equivalent) and leave for 30 minutes. (See Figure 10.)

e. Start the vehicle to confirm successful ECU communication.
NOTE:
If ECU communication is not completed correctly, the engine will not start and DTC
B2799 will be set. DTC B2799 will be cleared after engine starts correctly. Operation

6. Engine ECU Replacement
When the Engine ECU is replaced, ECU communication must be completed.
ECU Communication must be performed between the transponder ECU and the
Engine ECU. Complete ECU communication using the following steps:
A. Insert registered Master Key into the ignition cylinder.
B. Turn ignition ON (engine OFF).
C. Short Tc and CG terminals of DLC3 using Diagnosis Check Wire
(SST 09843±18040 or equivalent) and leave for 30 minutes. (See Figure 11.)

REPAIR MANUAL SUPPLEMENT: VEHICLE PULLING TO ONE SIDE ± ST004-01 RevisedDecember 21, 2001
Page 10 of 11
STEP 3:
Adjust cross camber to eliminate vehicle pulling.
HINT:
If the tires are placed in the positions they were in during tire rotation when the least
amount of vehicle pulling occurred, wheel alignment can be performed with a minimal
amount of adjustment.
WHEN VEHICLE PULLS TO LEFTWHEN VEHICLE PULLS TO RIGHT
Increase right front camber and decrease left
front camber until vehicle pulling is eliminatedIncrease left front camber and decrease right
front camber until vehicle pulling is eliminated
NOTE:
Keep the cross camber within 1
or less.
Keep the camber of each wheel within specifications (+/±45' of center value).
If adjustment exceeds the specifications, uneven tire wear will result.
5. Camber Adjustment Method
NOTE:
After the camber has been adjusted,
inspect the toe±in.
NOTE:
The method of camber adjustment
differs for different models, so please
refer to the repair manual of the
vehicle involved. (This is a sample
from the RX 300 Repair Manual).
A. Remove the front wheels and
ABS speed sensor clamp.
B. Remove the two nuts on the lower
side of the shock absorber.
C. Coat the threads of the nuts with
engine oil.
D. Temporarily install the two nuts.
E. Adjust the camber by pushing or
pulling the lower side of the shock
absorber in the direction in which
the camber adjustment is
required.
F. Tighten the nuts.
