DATA LIST / ACTIVE TEST

DATA LIST

NOTICE:

  • In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
  • When using the Techstream with the engine switch off, connect the Techstream to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the Techstream and the vehicle begins. Then select the vehicle type under manual mode and enter the following menus: Body Electrical / Smart Key. While using the Techstream, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the Techstream and the vehicle.

HINT:

Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

(a) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / Smart Key, Main Body, Power Source Control or Combination Meter / Data List.

(e) Read the Data List according to the display on the Techstream.

Unmatched Vehicle-ID

Key No. (incorrect or correct)

Yes or No

Yes: Communication malfunction

No: Communication normal

The vehicle ID registered in the vehicle and the vehicle ID registered in the electrical key transmitter sub-assembly are different (if a key from another vehicle is brought into the vehicle exterior detection area while the doors are locked, "Yes" is displayed for "Unmatched Vehicle-ID" in the Data List).

Other potential causes:

  • An electrical key transmitter sub-assembly from a different vehicle is being used.
  • A communication error due to wave interference.
  • The electrical key transmitter sub-assembly or certification ECU (smart key ECU assembly) is malfunctioning.

No Response

Communication response

Yes or No

Yes: Communication malfunction

No: Communication normal

The vehicle IDs registered in the vehicle and electrical key transmitter sub-assembly match, but there is no response from the electrical key transmitter sub-assembly. (If the electrical key transmitter sub-assembly is not in the detection area or the transmitter battery is depleted resulting in a matching code not being detected when a lock switch or the engine switch is pressed, etc., "Yes" is displayed for "No Response" in the Data List. If there is wave interference in the LF band that the vehicle uses for transmission or the RF band that the electrical key transmitter sub-assembly uses for transmission, "Yes" may be displayed for "No Response" in the Data List.)

Other potential causes:

  • An electrical key transmitter sub-assembly from a different vehicle is being used.
  • The electrical key transmitter sub-assembly or certification ECU (smart key ECU assembly) is malfunctioning.

Unmatch Code or Form

Code format (incorrect or correct)

Yes or No

Yes: Communication malfunction

No: Communication normal

There is an error in the data sent from the electrical key transmitter sub-assembly (if there is wave interference in the RF band that the electrical key transmitter sub-assembly uses for transmission, "Yes" may be displayed for "Unmatch Code or Form", "No Response", "ID Code Difference(Resp)" and "C Code Difference" in the Data List).

Other potential causes:

  • An electrical key transmitter sub-assembly from a different manufacturer is being used.
  • The electrical key transmitter sub-assembly or certification ECU (smart key ECU assembly) is malfunctioning.

Key Low Battery

Transmitter battery depleted

Yes or No

Yes: Transmitter battery depleted

No: Transmitter battery not depleted

The electrical key transmitter sub-assembly sends voltage information to the certification ECU (smart key ECU assembly) when it is transmitting. "Yes" is displayed for the Data List item "Key Low Battery" when this voltage information indicates 2.2 V or less. This Data List item should be checked when the electrical key transmitter sub-assembly is at room temperature (example: at -20°C (-4°F), "Yes" may be displayed even if the transmitter battery is new).

Power Save Cnt 10 Min.

Number of times power saving control is activated due to electrical key transmitter sub-assembly being in detection area for 10 minutes or more

0 to 255

Within range of 0 to 255

If the electrical key transmitter sub-assembly is in a vehicle exterior detection area, communication is frequently performed between the vehicle and electrical key transmitter sub-assembly, resulting in an increase in transmitter battery power consumption. To prevent the transmitter battery from becoming fully depleted, if the electrical key transmitter sub-assembly is left in the detection area for 10 minutes or more, the smart key system automatically deactivates the exterior detection area the electrical key transmitter sub-assembly is in. If the doors are locked/unlocked with a wireless operation or by the mechanical key, the system resumes operation.

Power Save Cnt 5 Days

Number of times power saving control 1 (vehicle exterior periodic signal transmission stop) is activated due to engine not being started for 5 days or more

0 to 255

ID Code Difference(Resp)

ID code (incorrect or correct)

Yes or No

Yes: Communication malfunction

No: Communication normal

The ID code registered in the vehicle and the ID code registered in the electrical key transmitter sub-assembly are different (if there is wave interference in the RF band that the electrical key transmitter sub-assembly uses for transmission, "Yes" may be displayed for "Unmatch Code or Form", "No Response", "ID Code Difference(Resp)" and "C Code Difference" in the Data List).

Other potential causes:

  • An electrical key transmitter sub-assembly from a different vehicle is being used.
  • The electrical key transmitter sub-assembly or certification ECU (smart key ECU assembly) is malfunctioning.

C Code Difference

Challenge code (incorrect or correct)

Yes or No

Yes: Communication malfunction

No: Communication normal

The electrical key transmitter sub-assembly sends a response code in response to the challenge code from the vehicle, but the response code is incorrect (if there is wave interference in the RF band that the electrical key transmitter sub-assembly uses for transmission, "Yes" may be displayed for "Unmatch Code or Form", "No Response", "ID Code Difference(Resp)" and "C Code Difference" in the Data List).

Other potential causes:

  • The electrical key transmitter sub-assembly or certification ECU (smart key ECU assembly) is malfunctioning.

ID Code Difference

Wireless ID code (incorrect or correct)

Yes or No

Yes: Communication malfunction

No: Communication normal

The ID code registered in the vehicle and the ID code registered in the electrical key transmitter sub-assembly are different. (If a wireless ID other than those for any of the registered electrical key transmitter sub-assemblies is detected, "Yes" is displayed for "ID Code Difference" in the Data List. If a wireless signal from the electrical key transmitter sub-assembly of another vehicle is detected, "Yes" is displayed for "ID Code Difference(Resp)" in the Data List.)

Other potential causes:

  • An electrical key transmitter sub-assembly from a different vehicle is being used.
  • A communication error due to external noise (RF).
  • The electrical key transmitter sub-assembly or certification ECU (smart key ECU assembly) is malfunctioning.

Immobiliser

Immobiliser system status determined by certification ECU

Set or Unset

Set: Immobiliser set (engine start prohibited) (engine switch off)

Unset: Immobiliser unset (engine start permitted) (engine switch on (ACC) or on (IG))

When the immobiliser system does not change to the unset state, this item can be used to determine if the cause is the certification ECU or ID code box.

Different Rolling Code

Rolling code (incorrect or correct)

Yes or No

Yes: Communication malfunction

No: Communication normal

The rolling code registered in the vehicle and the rolling code registered in the electrical key transmitter sub-assembly are different

Other potential causes:

  • An electrical key transmitter sub-assembly switch is pressed 100 times or more in a location where the radio waves cannot reach the vehicle.
  • A communication error due to external noise (RF).
  • The electrical key transmitter sub-assembly or certification ECU (smart key ECU assembly) is malfunctioning.
