Part 5

INTRODUCTION: REPAIR INSTRUCTION: INITIALIZATION - Continued


65. MAYDAY ECU REGISTRATION / ENROLLMENT
(a) Turn the power switch ON (IG) and wait for the 5 second LED flash start sequence. Press the SERVICES button when the mayday ECU is set normally and confirm that the following demo message is provided.
"Hello and welcome to LEXUS Link."
If the message is not provided, perform the "MAYDAY ECU INITIALIZATION BUTTON SEQUENCE" again.
(b) 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.

(c) 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 the power switch 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.

66. 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).

(a) Turn the power 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 an approximately 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.)
(b) 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.
(c) The system will then perform the same start sequence as described above. After this start sequence completes, cycle the power switch 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 active enrolled).

67. MAYDAY BATTERY CONFIRMATION
(a) After mayday battery replacement and completion of the "MAYDAY BATTERY REGISTRATION BUTTON SEQUENCE", turn the power switch OFF and ON (IG), and 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.

68. INITIALIZE POWER WINDOW CONTROL SYSTEM (POWER WINDOW REGULATOR MOTOR (ALL DOORS))
CAUTION: When the power window regulator motor is reinstalled or replaced, the power window control system must be initialized. Functions such as the AUTO UP/DOWN, jam protection and key-off do not operate if the initialization is not performed.
HINT: When the battery is replaced, it is not necessary to initialize the power window regulator motor.
NOTICE:
- When the power window regulator motor assembly is replaced, DTC B2313 is output. Clear the DTC after the initialization.
- When performing initialization, do not perform any other procedures.
- After a door glass or a door glass run has been replaced, the jam protection function may operate unexpectedly when the AUTO UP function is used, due to detection of the different operation learned value of the door glass movement speed. In such cases, the AUTO UP function can be resumed by repeating the following operation at least 5 times:
1 Open the power window by fully pushing down the switch.
2 Close the power window by fully pulling up the power window switch and holding it at the AUTO UP position.
- If the initialization is not completed properly, the LIN communication system may have a malfunction.

(a) Initialization procedures when replacing the power window regulator motor with new one
(1) Connect the battery and turn the power switch ON (IG). (At this time, the LED on the power window regulator switch blinks to indicate that it is ready for initialization.)
(2) Fully open the window by fully pushing the power window regulator switch, and hold the switch for 1 second or more after the window is fully opened.
(3) Fully close the power window by fully pulling the power window regulator switch, and hold the switch for 1 second or more after the window is fully closed to reset the glass position. The LED on the power window regulator switch changes from blinking to illuminated to indicate that the initialization is complete.
(b) Initialization procedures when removing/installing the power window regulator motor assembly
(1) Connect the battery and turn the power switch ON (IG).
(2) Fully close the power window by fully pulling the power window regulator switch, and hold the switch for 6 seconds or more after the window is fully closed. (If the power window does not move or stops halfway even when the switch is fully pulled, release the switch and fully pull it again.)
(3) Fully open the window by pushing down the power window regulator switch, and hold the switch for 1 second or more after the window is fully opened.
(4) Release the power window regulator switch. Then fully push and hold the switch 4 seconds or more.
(5) Fully close the power window by fully pulling the power window regulator switch, and hold the switch 1 second or more after the window is fully closed to reset the glass position the initialization is complete.
(c) Initialization procedures when the power window does not fully open
(1) Connect the battery and turn the power switch ON (IG).
(2) Fully close the power window by fully pulling the power window regulator switch, and hold the switch for 6 seconds or more after the window is fully closed. (If the power window does not move or stops halfway even when the switch is fully pulled, release the switch and fully pull it again.)
(3) Fully open the window by pushing down the power window regulator switch, and hold the switch for 1 second or more after the window is fully opened.
(4) Release the power window regulator switch. Then fully push and hold the switch 4 seconds or more.
(5) Fully close the power window by fully pulling the power window regulator switch, and hold the switch 1 second or more after the window is fully closed to reset the glass position the initialization is complete.

74. INITIALIZE SLIDING ROOF DRIVE GEAR
NOTICE:
- When the sliding roof glass is replaced or removed and installed, or the drive gear assembly is replaced, the sliding roof drive gear requires initialization (pulse sensor initial position setting), as the glass position cannot be determined. If initialization is not performed, the AUTO slide open and close / tilt up and down function may not operate, or the sliding roof may move in reverse or become misaligned.
- During initialization, do not apply a physical shock, such as opening/closing a door or driving the vehicle at 5 km/h (3.10 mph) or more, to the vehicle and do not perform the following electrical operations:
1 Starting the hybrid control system (cranking the engine)
2 Turning the power switch from ON (IG) to OFF
