    1. *: In order to prevent the auxiliary battery from being depleted when the vehicle is shipped long distances, a fuse that cuts unnecessary electrical load while the vehicle is being shipped is set in the circuit. If the fuse is removed, the circuit becomes open. If the fuse that is between the auxiliary battery and terminal CUTB is removed and the circuit is open, the certification ECU (smart key ECU assembly) changes to a certain control mode (example: the transmission of electric waves every 250 ms. that form the detection area stops).
    If the result is not as specified, there may be a malfunction on the wire harness side or the fuse is removed.

  3. Reconnect the H1 certification ECU (smart key ECU assembly) connector.
