Current Data Display & Save/System Operation Check Mode

  1. [Current Data Display & Save]
    CAUTION: In the following table, the value listed in the normal condition is a reference value. Do not depend on reference value only when judging if the part is faulty.
    NOTE: By using the SSM3 and viewing [Current Data Display & Save], you can find out about the value and status related to items such as the switch, the sensor, or the actuator without having to remove the relevant parts. Because the non-intrusive inspection allows you to read the intermittent statuses or signals without interfering with parts or lines, it is very convenient. By reading the [Current Data Display & Save] information at the initial stage of troubleshooting, you can save on time for diagnosing trouble.
    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] →[Collation ECM] →[Current Data Display & Save]
    5. Based on the contents of the SSM3 display, read the [Current Data Display & Save].

      OK: Communication to release the immobilizer setting between the collation ECM (smart key ECM assembly) and ECM starts.
      Even when the condition to release the immobilizer setting is met, if the [NG] is displayed in the items and [OK] is displayed in the items in the engine start request, ECM may be defective. If the engine cannot be started, use this [Current Data Display & Save] while the troubleshooting is performed.
      NOTE:
      (1) This indicates that there is a problem in the communication type between the electrical key transmitter sub-assembly and the collation ECM (smart key computer assembly). Possible fault causes include the external radio waves, or the faulty electrical key transmitter sub-assembly, or collation ECM (smart key ECM assembly), use of other vehicle electrical key transmitter sub-assembly.
      (2) This indicates that the wake-up signal communication is possible. ([Yes] indicates that the LIN communication signal is sent to start the confirmation operation.) If the steering lock motor operates normally and IGE ON signal is received (steering lock work request), or the communication occurs between the ID code box (immobilizer code ECM)*9, or collation ECM (smart key ECM assembly)*10 and ECM, the displayed item is changed to [Yes].
      (3) This indicates that the engine start permission request signal (EGST) sent from ECM (smart key ECM assembly) is received by the ID code box (immobilizer code ECM)*9 or the collation ECM (smart key ECM assembly)*10.
      (4) This indicates the collation results of the collation code for the collation ECM (smart key ECM assembly) and ID code box (immobilizer code ECM) collation code.
      (5) This indicates the collation results of the collation code for the steering lock actuator assembly (steering lock ECM) and the ID code box (immobilizer code ECM) *9 or collation ECM (smart key ECM assembly)*10.
      • When the steering lock actuator assembly (steering lock ECM) receives the unlock request from the collation ECM (smart key ECM assembly), the confirmation operation for ID code box (immobilizer code ECM) L code is performed. When the L code is matched, the steering lock actuator assembly (steering lock ECM) unlocks the steering. But when the S code check result is not matched, the steering lock does not unlock.
      (6) The collation ECM (smart key ECM assembly) outputs the steering lock/unlock request for 10 seconds after the engine switch is ON (ACC) or ON (IG) or the engine start operation has been performed.
      (7) The collation ECM (smart key ECM assembly) outputs the steering lock request for 10 seconds after the engine switch is OFF, or after the door is opened with the shift lever positioned in P.*11.
      (8) This indicates that the ID code box (immobilizer code ECM)*9, or collation ECM (smart key ECM assembly)*10 receives the confirmation information from the ECM. The display changes to [OK] if the ECM can send the information.
      (9) With ID code box
      (10) Without ID code box
      (11) With automatic transmission
      1. Refer to the items in following [Current Data Display & Save] for the actual vehicle data.

        NOTE: With the IG OFF and the shift lever in P*6, perform the following operation to confirm the power supply mode.

        *1: Without depressing the brake pedal*6 or clutch pedal*7, push the engine switch to confirm the power supply mode is turned ON (ACC).

        *2: Without depressing the brake pedal*6 or clutch pedal*7, push the engine switch to confirm the power supply mode turns to ON (IG).

        *3: Depress the brake pedal*6 or clutch pedal*7 (stop light switch*6 or clutch start switch*7 turns to ON).

        *4: Push the engine switch to confirm the power supply mode turns to ON.

        *5: Open the door (the steering lock operation starts when the door opens).

        *6: With automatic transmission

        *7: With manual transmission

  2. [System Operation Check Mode]
    NOTE: By performing the [System Operation Check Mode] using the SSM3, relay, VSV, actuator and other devices can be operated without removing parts. This type of non-intrusive function inspection is very useful because the intermittent operation is possible without interference with parts or wiring. Diagnostic time can be reduced by performing the [System Operation Check
    Mode] at an early stage of troubleshooting. The information of [Current Data Display & Save] can be displayed while performing the [System Operation Check Mode].
    1. Connect the SSM3 to the DLC3.
    2. Turn IG SW to ON.
    3. Turn on the SSM3.
    4. Enter the following menu items: [Integ. unit mode] →[Work Support] →[System Operation Check Mode].
    5. Based on the information displayed by the SSM3, execute [System Operation Check Mode].
