Inspection steps

CAUTION:
  • The entry & start system has functions that use the CAN communication. Before performing troubleshooting, perform the inspection in "How to troubleshoot", and check that there are no communication problems. (Refer to HOW TO PROCEED WITH TROUBLESHOOTING  )
  • Before replacing the collation ECM (smart key ECM assembly), refer to "entry & start system (entry function)". (Refer to PARTS LOCATION )
  • After repair, perform the [DTC output confirmation operation], and check that the DTC is not output again.
  • Before performing the following inspection steps, check the fuses related to this system.
  1. Reading the values using the SSM3 (engine speed)
    1. Connect the SSM3 to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn on the SSM3.
    4. Input the following menus: [Keyless access system] →[Power Supply ECM] →[Current Data Display & Save]
    5. Based on the contents of the SSM3 display, read the [Current Data Display & Save].

      Result

      Result Go to
      NG A
      OK B

      B: Proceed to the "EFI system" ("How to troubleshoot")

      A: Go to next step

  2. Checking the harnesses and connectors (power supply) (Refer to INSPECTION STEPS  )

    NG: Repair or replacement of the harnesses or connectors of the circuits that connect to the power source

    OK: Go to next step

  3. Checking the harnesses and connectors (grounding) (Refer to INSPECTION STEPS  )

    NG: Repair or replacement of the harnesses or connectors

    OK: Go to next step

  4. Checking the harnesses and connectors (collation ECM (smart key ECM assembly) - ECM)
    1. Remove the D48 connector of the collation ECM (smart key ECM assembly).
    2. Remove the A35 connector of the ECM.
    3. Measure the resistance according to the following table.

      Resistance

      RESISTANCE REFERENCE

      Inspection terminals Inspection conditions Standard value
      D48-17 (TACH) - A35-15 (TACHO) Always 1 Ωor less
      D48-17 (TACH) - chassis ground Always 10 kΩ or more

      NG: Repair or replacement of the harnesses or connectors

      OK: Go to next step

  5. Unit inspection of the collation ECM (smart key ECM assembly)
    1. Reconnect the A35 connector of the ECM.
    2. Reconnect the D48 connector of the collation ECM (smart key ECM assembly).
    3. Refer to the TABLE  below and check the signal waveform.
