Toyota Tacoma 2015-2018 Service Manual: Registration

REGISTRATION

PROCEDURE

1. DESCRIPTION OF CODE REGISTRATION

HINT:

  • Registering an ID code enables the entry and start function, wireless door lock control function and engine immobiliser function to be operated.
  • Code registration is needed when the certification ECU (smart key ECU assembly), steering lock ECU (steering lock actuator or upr bracket assembly) or electrical key transmitter sub-assembly is replaced with a new one.
  • This vehicle does not have a key slot. Therefore, while facing the logo side of the electrical key transmitter sub-assembly towards the engine switch, hold the transmitter near the engine switch as shown in the illustration to register the electrical key transmitter sub-assembly.

2. KEY REGISTRATION PROCEDURES WHEN ADDING OR REPLACING KEY OR WHEN KEY IS LOST

HINT:

  • The following procedures require the use of the Techstream:
    • - New key ID registration
    • - Additional key ID registration
    • - Key ID erasure
  • A maximum of 7 keys can be registered (this includes any keys registered when the vehicle was purchased).
  • In the chart below, the numbers in the "Procedure" column (1, 2, 3, etc.) indicate the step numbers. Perform the steps in numerical order.

Customer Request/Condition

Registration Procedure Condition

Procedure

Refer to

Registering additional key

Customer must bring at least 1 key

1. Register additional keys as necessary (additional key ID registration)

PROCEDURE "C"

  • Replacing a key (e.g., when replacing an old key with a new one)

NOTICE:

If the customer brings at least 1 key, it is possible to perform these procedures. However, if any additional keys are registered before reregistering the customer's keys, the customer's keys cannot be reregistered and become unusable. Therefore, if the customer does not bring all of their keys, be sure to explain to them that any keys not brought will become unusable after additional keys are registered.

HINT:

After key ID erasure, any remaining keys that are not reregistered at this time cannot be used. Therefore, immediately after key ID erasure, be sure to reregister all available remaining keys.

Customer must bring at least 1 key

1. Using remaining key, clear all registered keys except one (key ID erasure)
