Registration [08/2013 - ]: Procedure
WARNING: This page is about a different car, the 2018 Toyota Corolla, 2017 Toyota Corolla, 2016 Toyota Corolla, 2015 Toyota Corolla, and 2014 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
- DESCRIPTION OF CODE REGISTRATION
HINT:
- Registering an ID code enables the smart key system function, wireless door lock control function and immobilizer function to be operated.
- Code registration is needed when the certification ECU (smart key ECU assembly), ID code box (immobilizer code ECU), steering lock ECU (steering lock actuator 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.
*1 Engine Switch *2 Electrical Key Transmitter Sub-assembly - 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
- - All Key ID erasure
- A maximum of 7 electrical key transmitter sub-assemblies can be registered (this includes any electrical key transmitter sub-assemblies 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 electrical key transmitter sub-assembly Customer must bring at least 1 electrical key transmitter sub-assembly 1. Register additional electrical key transmitter sub-assemblies as necessary (additional key ID registration) PROCEDURE "C" - Replacing a electrical key transmitter sub-assembly (e.g., when replacing an old electrical key transmitter sub-assembly with a new one)
- Making a lost electrical key transmitter sub-assembly unusable
NOTE:HINT: After electrical key transmitter sub-assembly ID erasure, any remaining electrical key transmitter sub-assemblies that are not reregistered at this time cannot be used. Therefore, immediately after electrical key transmitter sub-assembly ID erasure, be sure to reregister all available remaining electrical key transmitter sub-assemblies.If the customer brings at least 1 electrical key transmitter sub-assembly, it is possible to perform these procedures. However, if any additional electrical key transmitter sub-assemblies are registered before reregistering the customer's electrical key transmitter sub-assemblies, the customer's electrical key transmitter sub-assemblies cannot be reregistered and become useless. Therefore, if the customer does not bring all of their electrical key transmitter sub-assemblies, be sure to explain to them that any electrical key transmitter sub-assemblies not brought will become useless after additional electrical key transmitter sub-assemblies are registered.
Customer must bring at least 1 electrical key transmitter sub-assembly 1. Using remaining electrical key transmitter sub-assembly, clear all registered electrical key transmitter sub-assemblies except one (key ID erasure) PROCEDURE "D" 2. Register additional electrical key transmitter sub-assemblies as necessary (additional key ID registration) PROCEDURE "C" All electrical key transmitter sub-assemblies are lost - 1. Reset all electrical key transmitter sub-assemblies (all keys ID erasure (key code reset) PROCEDURE "E" 2. Register all electrical key transmitter sub-assemblies (new key ID registration) PROCEDURE "A" - The following procedures require the use of the Techstream:
- PART REPLACEMENT AND KEY REGISTRATION PROCEDURES
- If a malfunctioning ECU is discovered through troubleshooting of the smart key system, use the ECU replacement and electrical key transmitter sub-assembly registration procedures in the table below.
HINT:
- The following procedures require the use of the Techstream:
- - New key ID registration
- - Additional key ID registration
- - Key ID erasure
- - ECU code registration
- A maximum of 7 electrical key transmitter sub-assemblies can be registered (this includes any electrical key transmitter sub-assemblies registered when the vehicle was purchased).
- Immediately after replacing the certification ECU (smart key ECU assembly), the Techstream item "A number of registered codes" should change to "0". If this item does not change to "0", the certification ECU (smart key ECU assembly) may be registered to another vehicle. A certification ECU (smart key ECU assembly) which is registered to another vehicle cannot be used.
