    A005LM7E02

    1. Disconnect the F65 certification ECU (smart key ECU assembly) connector.

    2. Measure the voltage and resistance according to the value(s) in the table below.

      Terminal No. (Symbol) Input/Output Wiring Color Terminal Description Condition Specified Condition Related Data List Item
      F63-5 (IG) - F65-11 (E) Input P - BR IG power supply Engine switch off → on (IG) Below 1 V → 11 to 14 V Ignition Switch
      F65-2 (+B) - F65-11 (E) Input W - BR +B power supply Always 9.5 to 16 V -
      F65-10 (CUTB) - F65-11 (E) Input Y - BR Dark current cut pin* Always 11 to 14 V -
      F65-11 (E) - Body ground - BR - Body ground Ground Always Below 1 Ω -

      • *: 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 (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 F65 certification ECU (smart key ECU assembly) connector.

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