1. Attach the 3 claws to install the spiral cable.
   WARNING:

   When replacing the spiral cable with a new one, remove the lock pin before installing the steering wheel assembly.

2. Connect the connectors to the spiral cable.
   NOTE:

   When handling the airbag connector, take care not to damage the airbag wire harness.

Refer to PROCEDURE - Step 9 [08/2015 - 08/2022] , or refer to PROCEDURE - Step 8 [08/2022 - ]

1. Turn the ignition switch off.
2. Disconnect the cable from the negative (-) battery terminal.
   WARNING:

   Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.

   NOTE:

   When disconnecting the cable, some systems need to be initialized after the cable is reconnected (Refer to INITIALIZATION [08/2015 - 08/2019] , or refer to INITIALIZATION [08/2019 - 08/2022] , or refer to INITIALIZATION [08/2022 - ] ).

4. If the spiral cable sub-assembly is not centered, center it.
   NOTE:

   Make sure to observe the following precautions, otherwise the spiral cable sub-assembly may be damaged.

   • Do not rotate the spiral cable sub-assembly with the battery connected and the ignition switch turned to ON.
   • Do not rotate the spiral cable sub-assembly using the airbag wire harness.

      Rotation Direction

      NOTE:

      If the spiral cable sub-assembly is rotated clockwise in this step, it may be damaged and may no longer be able to be centered. Make sure to only rotate the spiral cable sub-assembly counterclockwise.

   2. If the connector is not positioned at the bottom of the rotation of the spiral cable sub-assembly when the spiral cable sub-assembly is turned until it stops, turn the spiral cable sub-assembly clockwise until the connector is positioned at the bottom as shown in the illustration.
