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


  1. CHECK CERTIFICATION ECU (SMART KEY ECU ASSEMBLY)

    B008L1DE12

    1. Disconnect the F1 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.

      Terminal No. (Symbol) Input/Output Wiring Color Terminal Description Condition Specified Condition Related Data List Item
      F1-18 (E) - Body ground - W-B - Body ground Ground Always Below 1 Ω -
      F1-4 (+B) - F1-18 (E) Input L - W-B Power supply Always 11 to 14 V -
      F1-15 (CUTB) - F1-18 (E) Input SB - W-B 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 installed 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 radio waves every 0.25 seconds, which form the detection area, stops).

    3. Reconnect the F1 certification ECU (smart key ECU assembly) connector.

    4. Measure the voltage and check for pulses according to the value(s) in the table below.

      5. Lock or unlock switch of electrical key transmitter sub-assembly not pressed → pressed

  2. CHECK MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) AND INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY


    1. Remove the main body ECU (multiplex network body ECU) from the instrument panel junction block assembly.


    2. Reconnect the instrument panel junction block assembly connectors.

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

      Tech Tips

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