DESCRIPTION OF CODE REGISTRATION
Tech Tips
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 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.

KEY REGISTRATION PROCEDURES WHEN ADDING OR REPLACING KEY OR WHEN KEY IS LOST
Tech Tips
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" |
Note 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. Tech Tips 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) | PROCEDURE "D" |
| 2. Register additional keys as necessary (additional key ID registration) | PROCEDURE "C" | ||
| All keys are lost | - | 1. Reset all keys (all keys ID erasure (key code reset)) | PROCEDURE "E" |
| 2. Register all keys (new key ID registration) | PROCEDURE "A" |

If there are any electronic devices near the driver seat which may cause wave interference, such as cell phones, personal computers, portable music players, other electrical key transmitter sub-assemblies, etc., turn them off or move them away from the driver seat.
KEY REGISTRATION (PROCEDURE "G")
ECU communication ID registration:
Note
The ECU communication ID should be registered when the certification ECU (smart key ECU assembly) is replaced in order for the ECU communication ID to match.
The engine cannot be started unless the ECU communication ID is registered.
After registration, pressing the engine switch may not start the engine on the first try. If so, press the engine switch again.
After the engine is started, clear DTC B2799 (code for ECM immobiliser communication error) using either of the following methods:
- Use the Techstream.
- Disconnect the cable from the negative (-) battery terminal for 30 seconds.
Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.
Turn the engine switch on (IG) (do not start the engine) and leave it as is for 30 minutes.
Turn the engine switch off and disconnect terminals 13 (TC) and 4 (CG).
Check that the engine starts and stays on for more than 3 seconds.
