SMART KEY SYSTEM (for Entry Function) TERMINALS OF ECU


  1. CHECK CERTIFICATION ECU (SMART KEY ECU ASSEMBLY)

    A01HYSPE30

    1. Disconnect the A43 and I78 certification ECU (smart key ECU assembly) connectors.

    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

      I78-6 (IG1D) - Body ground Output P - Body ground IG1 signal 20°C (68°F) 40.74 to 59.49 Ω IG1 Relay Monitor(Outside)
      A43-9 (IG2D) - Body ground Output R - Body ground IG2 signal 20°C (68°F) Approximately 302.97 Ω IG2 Relay Monitor(Outside)
      I78-4 (ACCD) - Body ground Output W - Body ground ACC signal 20°C (68°F) 81.49 to 118.98 Ω ACC Relay Monitor
      A43-10 (CUTB) - A43-11 (E) Input L - W Dark current cut pin* Always 11 to 14 V -

      • *: In order to prevent the vehicle 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 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 A43 and I78 certification ECU (smart key ECU assembly) connectors.

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