Title: THEFT DETERRENT / KEYLESS ENTRY: SMART KEY SYSTEM (for Entry Function (except TMMMS Made)): DATA LIST / ACTIVE TEST; 2023 MY Corolla Corolla Hatchback Corolla HV GR Corolla [09/2022 - 11/2022]

DATA LIST / ACTIVE TEST

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 GTS with the ignition switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins.

    Then select Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Start Key(CAN). While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.

  • When performing an inspection, make sure that "ACC Customize" is set to "ON" using the multi-display.

  • When "ACC Customize" is set to "ON" (ACC supply power enabled), the certification ECU (smart key ECU assembly) controls the ACC relay on and off. When "ACC Customize" is set to "OFF" (ACC supply power disabled), the certification ECU (smart key ECU assembly) and radio and display receiver assembly control the ACC relay on and off.

    Therefore, inspection conditions and results may differ depending on whether "ACC customize" is set to ON or OFF when inspecting the Data List.

Electronic Key No Response

Communication response

No or Yes

No: Communication normal

Yes: Communication malfunction

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 "Electronic Key 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 "Electronic Key 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.

Unmatched Response Code or Form

Code format (incorrect or correct)

No or Yes

No: Communication normal

Yes: Communication malfunction

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 "Unmatched Response Code or Form", "Electronic Key No Response", "ID Code Difference" 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

No or Yes

No: Transmitter battery not depleted

Yes: Transmitter battery 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).

C Code Difference

Challenge code (incorrect or correct)

No or Yes

No: Communication normal

Yes: Communication malfunction

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 "Unmatched Response Code or Form", "Electronic Key No Response", "ID Code Difference" 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.

10 Minutes Power Save Counter

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.

5 Days Power Save Counter

Number of times power saving control 1 (vehicle exterior periodic signal transmission stop) is activated due to hybrid control system*2 or engine*3 not being started for 5 days or more

0 to 255

Within range of 0 to 255

-

14 Days Power Save Counter

Number of times power saving control 2 (lock/unlock sensor of front door outside handle assembly of front passenger door disabled) is activated due to hybrid control system*2 or engine*3 not being started for 14 days or more

0 to 255

Within range of 0 to 255

-

ID Code Difference

Wireless ID code (incorrect or correct)

No or Yes

No: Communication normal

Yes: Communication malfunction

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 "Response ID Code Difference" 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.

Rolling Code Difference

Rolling code (incorrect or correct)

No or Yes

No: Communication normal

Yes: Communication malfunction

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.

ACTIVE TEST

HINT:

Using the GTS to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

(a) Connect the GTS to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the GTS on.

(d) Enter the following menus: Body Electrical / Smart Key or Main Body / Active Test.

(e) Perform Active Test according to the display on the GTS.
