    CHECK CERTIFICATION ECU (SMART KEY ECU ASSEMBLY)


    1. Disconnect the G71, L31 and A22 certification ECU (smart key ECU assembly) connectors.

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

      Tip:

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

      • Vehicle Speed Signal

      • *: 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 installed 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 radio waves every 0.25 seconds, which form the detection area, stops).

    3. Reconnect the G71, L31 and A22 certification ECU (smart key ECU assembly) connectors.

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

    CHECK POWER SWITCH


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

      Tester Connection Wiring Color Input/Output Terminal Description Condition Specified Condition Related Data List Item
      A-6 (AGND) - Body ground - - Transponder key amplifier ground Always Below 1 Ω -
      A-7 (TXCT) - A-6 (AGND) - Input Immobiliser communication input Power switch off, brake pedal not depressed, 30 seconds or more after driver door opened and then closed Below 1 V -
      A-8 (CODE) - A-6 (AGND) - Output Immobiliser communication output Power switch off, brake pedal not depressed, 30 seconds or more after driver door opened and then closed Below 1 V -
      A-10 (VC5) - A-6 (AGND) - Input Transponder key amplifier power supply Power switch off, brake pedal not depressed, 30 seconds or more after driver door opened and then closed Below 1 V -

    2. Check for pulses according to the value(s) in the table below.

      Tester Connection Wiring Color Input/Output Terminal Description Condition Specified Condition Related Data List Item
      A-7 (TXCT) - A-6 (AGND) - Input

      Signal input from certification ECU (smart key ECU assembly)

      (Code sent from certification ECU (smart key ECU assembly) to transponder key amplifier built into power switch, and then transmitted by transponder key amplifier antenna as radio waves)

      		 Power switch off, electrical key transmitter sub-assembly not in cabin, within 30 seconds after power switch pressed

      Pulse generation

      (See waveform 1)

      Entry&Start


      • BCC Malfunction

      • Abnormal Status

      • Different Encrypt Code

      • Different Serial Number

      • Frame Error

      • Response

      Tip:

      If immobiliser key code verification communication is not performed correctly, the malfunction may be indicated by one or more of the Data List items listed above
      A-8 (CODE) - A-6 (AGND) - Output

      Signal output to certification ECU (smart key ECU assembly)

      (Radio waves from transponder key amplifier built into power switch used to detect key information. Key information then sent to certification ECU (smart key ECU assembly))

      		 Power switch off, power switch pressed with electrical key transmitter sub-assembly held near power switch*

      Pulse generation

      (See waveform 2)
      A-10 (VC5) - A-6 (AGND) - Input

      Transponder key amplifier power supply

      (Power supplied from certification ECU (smart key ECU assembly) when transponder key amplifier built into power switch activated)

      		 Power switch off, electrical key transmitter sub-assembly not in cabin, within 30 seconds after power switch pressed

      Pulse generation

      (See waveform 3)
      Tip:

      *: Remove the transmitter battery before performing this inspection.

    3. Using an oscilloscope, check the waveform.

      Note:

      The waveform shown in the illustration is an example for reference only. Noise, chattering, etc. are not shown.
