      • *: In order to prevent the 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 battery and terminal CUTB is removed and the circuit is open, the certification ECU 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 G26 certification ECU connector.

    4. Measure the voltage according to the value(s) in the table below.
