HINT: This procedure is for switching a new Mayday ECU from the Factory Mode into Demo Mode.
a. Turn the engine switch from off to on (IG) (engine does not have to be running).
b. 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.
c. 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).
d. 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 the DTC chart.
- Do not push any buttons during any start sequences (LED flashing or voice prompts).
66. MAYDAY ECU REGISTRATION / ENROLLMENT
a. Turn the engine 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..."

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 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.
67. 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 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.)
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 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).
68. MAYDAY BATTERY CONFIRMATION
a. 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.
