ENTRY AND START SYSTEM(for Entry Function) TERMINALS OF ECU


  1. CHECK CERTIFICATION ECU (SMART KEY ECU ASSEMBLY)

    A01V26QE03

    1. Disconnect the F47 and F48 certification ECU (smart key ECU assembly) connector.

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

      Tech Tips

      Measure the values on the wire harness side with the connector disconnected.

      Tester Connection Input/Output Wiring Color Terminal Description Condition Specified Condition Related Data List Item
      F48-1 (E) - Body ground - BR - Body ground Ground Always Below 1 Ω -
      F47-5 (+B) - F48-1 (E) Input BE - BR +B power supply Power switch off 11 to 14 V -
      F47-4 (CUTB) - F48-1 (E) Input Y - BR Dark current cut pin* Power switch off 11 to 14 V -

      • *: In order to prevent the vehicle 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 vehicle 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 0.25 seconds. 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 F47 and F48 certification ECU (smart key ECU assembly) connector.

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