1. Make sure the vehicle is stationary during the test.
2. Insert a compact disc (NOT the Lexus Master CD) to make sure the radio can accept
and eject the disc without damaging it.
3. Check the Lexus Master CD for any unintended scratches or dirt. Wipe away dirt
using a glass cleaning cloth. If the disc is damaged, order a replacement master CD.
4. Insert the Lexus Master CD and change to track number 9.
5. Play the track for one minute.
A. If skips are heard, replace the CD player.
B. If NO skips are heard, the CD player is working normally. Check the customer's
CDs for scratches or other damage to the discs. Confirm that the customer is
using a pre-recorded CD, NOT CD-Rs or CD-RWs as they may NOT have been
burned properly.
NOTE:
Tracks 1 ± 8 and 11 ± 14 are reference tracks. They can be used, but the conditions
are less severe than track 9. Do NOT use tracks 10 and 15.
Track 9 (0.8 mm scratch) is much more severe than the Lexus engineering
specification in order to ensure customer satisfaction. If the customer's radio
passes this test, a replacement radio will NOT improve the performance.
This disc has been specially manufactured with a physical defect for the purposes
of testing the CD player's performance. It is NOT possible to make copies of this
disc that can be used to test the CD player's performance. Required

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
