TIRE PRESSURE WARNING SYSTEM (REGISTRATION)
1. DESCRIPTION OF CODE REGISTRATION
  It is necessary to register the transmitter ID in the tire pressure warning ECU when replacing the tire pressure warning valve and transmitter and/or tire pressure warning ECU.
  
  Prepare all transmitter ID data before starting registration.
  1. Before registration
    1. In case of tire pressure warning ECU replacement.
      1. Read the registered transmitter IDs that are stored in the old ECU using the Techstream and note them down.
      2. If reading stored transmitter IDs is impossible due to malfunctions of components such as the tire pressure warning antenna and receiver, remove the tires from the wheels and check the IDs located on the tire pressure warning valves and transmitters.
    2. In case of tire pressure warning valve and transmitter replacement.
      1. Take a note of the 7 digit number (transmitter ID) written on the tire pressure warning valve and transmitter.
        
        Fig 6: Identifying 7 Digit Number (Transmitter ID) On Tire Pressure Warning Valve And Transmitter
        Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
        
        NOTE: The transmitter ID is written on the tire pressure warning valve and transmitter. It will be unable to be read after installing the tire pressure warning valve and transmitter on the tire and wheel. Therefore, take a note of the transmitter ID before installing the tire pressure warning valve and transmitter.
      2. REGISTER TRANSMITTER ID
        
        Set the air pressure of all wheels to the specified value.
        
        Turn the engine switch OFF.
        
        Connect the Techstream to the DLC3.
        
        Turn the engine switch ON (IG) and the tester ON.
        
        Enter the menu items in this order: Chassis/Tire Pressure Monitor/Utility/ID Registration/
        
        Perform the procedures displayed on the Techstream.
        
        "UTILITY REGIST TIRE SET" screen is displayed. Then, press "YES".
        
        "UTILITY REGIST TIRE SET" screen is displayed. Then, press "ENTER".
        
        Confirmation of transmitter ID registration.
        
        Enter the menu items in this order:
        DIAGNOSIS/OBD/MOBD/CHASSIS/TIRE PRESSURE/DATA LIST.
        
        Read the "TIRE PRESS" values.
        NOTE:
        
        It may take up to about 2 or 3 minutes to update the tire pressure data. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2125/25.
        
        If the IDs have not been registered, DTC C2171/71 is set in the tire pressure warning ECU after 3 minutes or more.
        
        If normal pressure values are displayed, the IDs have been registered correctly.
        
        If the tire pressure values are not displayed after a few minutes, the IDs may be incorrect or the system may have a malfunction.
        
        The tire pressure information reception condition can also be confirmed through the multi-information display's tire pressure display screen.
        
        After all IDs are registered, DTC C2126/26 is set in the tire pressure warning ECU and the tire pressure warning light blinks for 1 minute and then comes on. When the tire pressure warning ECU successfully receives radio waves from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is deleted and the tire pressure warning light goes off.

CAUTION: The Techstream must be used with air bleeding and fluid replacement. If not used, the air bleeding and fluid replacement will be incomplete, which is hazardous and may lead to an accident.

Fig 22: ABS Warning Light And Brake Warning Light Blinking Pattern

Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

NOTE:

When replacing the brake fluid, replace the front and rear brake fluid as a set.
Perform fluid replacement with the shift lever on P and the parking brake set.
Perform fluid replacement while maintaining the brake fluid level between the MIN/MAX level on the brake fluid reservoir.
As brake fluid may overflow when bleeding air, do not place the fluid can on the reservoir filler opening.
Air bleeding will be difficult if the following occurs: 1) the brake fluid reservoir's No. 2 brake actuator hose (the hose between the brake accumulator pump and brake fluid reservoir) is lowered into the fluid and air enters the hose; and 2) during the fluid replacement procedure, air enters the brake accumulator pump while operating the pump motor.
While performing fluid replacement, the accumulator pressure drop may cause a buzzer to sound. As there is no problem, continue with the fluid replacement.
During fluid replacement, DTCs for pressure sensor malfunctions, etc. may be stored. After fluid replacement and if instructed in the procedures, clear the DTCs.
Do not allow brake fluid to contact the vehicle's paint surfaces. If contact occurs, clean it off immediately.

HINT:

For air bleeding, refer to the PRECAUTION .
Air bleeding with the Techstream cannot be performed when the engine switch is on (IG) or when the parking brake is not operating (electric parking brake operation signal is not input into skid control ECU).
While performing air bleeding, a display and navigation assembly (with HDD navigation system) or multi-display (without HDD navigation system) malfunction warning is displayed. However, there is no malfunction. After performing air bleeding, erase the warning using the screen's menus.

FILL RESERVOIR WITH BRAKE FLUID
NOTE:
- As brake fluid may overflow when bleeding air, do not place the fluid can on the reservoir filler opening.
- If brake fluid leaks onto any painted surface, clean it off completely.

  2. The mayday ECU will perform the Factory Mode Start Sequence for approximately 30 seconds.
    HINT:
    - In Factory Mode, for each ignition cycle OFF to ON (IG), or after checking or clearing DTCs, the ECU will perform a start sequence that includes a Japanese prompt and flashing LEDs (approximately 30 seconds). Then the LEDs will turn off. Do not push any buttons during this start sequence.
    - If there is a DTC detected during this Factory Mode Start Sequence, after the start sequence, the red LED will remain on and a Japanese prompt will repeat 5 times. Do not press any buttons during these prompts.
  3. BUTTON SEQUENCE:
    While pressing and holding the VOL+ button, press and release the PHONE button 5 times within 15 seconds, then release the VOL+ button. When switched to Demo Mode, each LED will flash one time then turn off (approximately 5 seconds).
  4. CONFIRMATION:
    Confirm Demo Mode by pressing the SERVICES button and listening for the demo prompt "Hello and welcome to LEXUS Link..." (the engine switch must be ON (IG) for the SERVICES button to function). Additionally, after each ignition cycle OFF to ON (IG), the LEDs will each flash one time each. This start sequence takes approximately 5 seconds. If Demo Mode is not confirmed, repeat the initialization procedure.
    
    HINT:
    - Before troubleshooting a DTC, attempt to initialize the ECU into Demo Mode with the button sequence. Then access DTCs and troubleshoot the ECU in Demo Mode. If necessary, DTCs can still be accessed in Factory Mode. However, the 30 second Factory Mode Start Sequence (and the Japanese prompt will repeat 5 times if a DTC is set) will occur after each ignition cycle OFF to ON (IG), and after each DTC check or clear. Do not press any buttons during this start sequence.
    - A red LED continuously on in any mode indicates that there is a current DTC set. Refer to 5 DTC chart.
    - Do not push any buttons during any start sequences (LED flashing or voice prompts).

  2. As the message states, press the SERVICES button again during the prompt to connect to the LEXUS Link call center.
    HINT:
    
    Usually this call will connect within 15 to 30 seconds. However, it may take several minutes depending on cellular service in the area. A progression tone (i.e., beep) will be heard every 5 seconds to indicate that the connection attempt is in progress.
  3. A LEXUS Link call center advisor will answer and instruct the technician on how to register/enroll the new mayday ECU. The ESN, STID and VIN may be required at this time.
    HINT:
    - If the LEXUS Link call center cannot be reached after several attempts using the SERVICES button, or a cell tower message is heard, such as "Welcome to Verizon Wireless, your phone is not active at this time...", call the LEXUS Link call center by pushing the EMERGENCY button.
    - The LED flash start sequence (approximately 5 seconds) after ignition is cycled or after checking/clearing DTCs remains present after enrollment. A green LED continuously on after this sequence indicates that the LEXUS Link System is activity enrolled.
3. MAYDAY BATTERY REGISTRATION
  HINT:
  - This procedure is required to register a new mayday battery and clear DTC 6-1. This procedure matches the new mayday battery with the new or used ECU.
  - A new mayday ECU always requires a new mayday battery (used mayday batteries should not be reused in a new ECU).
  - If the new replacement ECU is packaged and already connected to the new mayday battery when it arrives from the factory, and current DTC 6-1 is not set, do not perform the new mayday battery registration (the battery is already registered to the ECU that it is connected to).
  1. Turn the engine switch from OFF to ON (IG) and wait for the start up sequence of LED flashing to complete. Do not press any buttons during this start up sequence.
    (Note that Demo Mode and active enrolled ECUs have approximately a 5 second LED flashing start sequence. Factory Mode has approximately 30 seconds of LED flashing with a Japanese voice prompt. Also note if a current DTC is set in Factory Mode after this start sequence. This can be confirmed if the red LED remains on and an additional Japanese prompt repeats 5 times.)
  2. BUTTON SEQUENCE:
    Press and hold the PTT button while completing the following sequence of button presses. VOL+, VOL+, VOL-, VOL-, VOL+, VOL+, VOL-, VOL-, VOL+, VOL+, VOL-, VOL-
    
    Release all buttons. This button press sequence should be performed within 15 seconds.
  3. The system will then perform the same start sequence as described above. After this start sequence completes, cycle the ignition to off then ON (IG). Wait for the start sequence to complete. The new mayday battery is now registered to the mayday ECU and DTC 6-1 should be cleared.
    HINT:
    
    The mayday battery registration can be done in any mode (Factory Mode, Demo Mode or activity enrolled).
4. MAYDAY BATTERY CONFIRMATION
  1. After replacement check: If the "MAYDAY BATTERY REGISTRATION BUTTON SEQUENCE" has been completed, turn the engine switch OFF and ON (IG), wait for the start sequence described in the "MAYDAY BATTERY REGISTRATION". Then check that current DTC 6-1 is cleared.
    NOTE: If the "MAYDAY BATTERY REGISTRATION BUTTON SEQUENCE" has not been completed correctly, current DTC 6-1 will continue to be detected even if the mayday battery is replaced with a new one. In this case, check to be sure the old battery is removed and the new battery is installed. Then perform the "MAYDAY BATTERY REGISTRATION BUTTON SEQUENCE" again.
