Keyless Id Not Using Scan Tool MB991958 (M.U.T.-III Sub Assembly) <USA Only>

When the keyless ID code is already registered in the transmitter, the keyless ID code can be registered without using the scan tool MB991958 (M.U.T.-III sub assembly) according to the following procedures.

1. Prepare all the transmitters for ID code registration before starting the operation.
2. Press the unlock button of the transmitter in which the keyless ID code is registered.
3. After pressing the unlock button, press the lock button within 4 seconds to less than 10 seconds.
4. Release the lock button within 10 seconds after pressing it.
5. Release the unlock button 0.5 seconds after releasing the lock button.
   NOTE: The WCM erases the keyless ID codes of the transmitters other than the operated transmitter.
   NOTE: The WCM sets the transmitter registration number to 1.
6. When the operations from Step  1 to Step  4 are completed, the door can be locked or unlocked, and the mode shifts to the customer-programming mode. Within 1 minute after the mode shifted to the customer-programming mode, the signal for registration is transmitted from the transmitter to be added.
   NOTE: How to transmit the transmitter registration signal
   1. Press the lock button and the unlock button of the transmitter to be added for 1 second or more simultaneously.
   2. Release the lock button and the unlock button simultaneously.
   3. After releasing the lock button and unlock button simultaneously, when 0.5 seconds or more has elapsed, press the unlock button.
   NOTE: The WCM receives the registration signal, and stores the keyless ID code of the transmitter.
   NOTE: The WCM adds the transmitter registration number by 1.
7. When the operation of Step  5 is finished, the door can be locked or unlocked to notify that the transmitter registration is completed.
8. To register another transmitter, repeat the operation of Step  5 within 1 minute after the previous transmitter registration.
9. The customer-programming mode is terminated by any of the following conditions.
   • When the registration of 8 transmitters are completed
   • When 1 minute has elapsed without registration after the shift to the customer-programming mode
   • when 1 minute has elapsed after previous transmitter registration
   • When the engine speed is more than 200 rpm
   • The EEPROM abnormality occurs [When the EEPROM abnormality occurs during the transmitter registration, delete all the transmitters stored (including the transmitters used for the shift to the customer-programming mode), and finish the customer-programming mode.]
