Caution / Notice / Hint

NOTE:

When using the Techstream with the engine switch off, connect the Techstream to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the Techstream and the vehicle begins. Then select the vehicle type under manual mode and enter the following menus: Body Electrical / Smart Access. While using the Techstream, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the Techstream and the vehicle.
If the certification ECU (smart key ECU assembly) is replaced, refer to the Smart Access System with Push-button Start (for Start Function).
Refer to REGISTRATION [10/2022 - 10/2023]
When replacing or inspecting the door control receiver and wire harness, do not change the position or length of the wire harness. If the wire harness is too close to the door control receiver, smart access system with push-button start and wireless control function performance may be affected.
Check that there are no electrical key transmitter sub-assemblies in the vehicle.
This DTC is not stored within 10 seconds of the engine switch being turned from on (IG) to off.
When replacing the door control receiver, read the transmitter IDs (tire pressure warning system) stored in the old ECU using the Techstream and write them down before removal.
It is necessary to perform initialization after registration of the transmitter IDs into the door control receiver if the door control receiver has been replaced.
