Toyota Yaris: Smart Key System (for Start Function) / Data List / Active Test
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.
- The steering lock ECU (steering lock actuator or upper bracket assembly) communicates with the GTS through the certification ECU (smart key ECU assembly) which uses CAN communication. If the CAN communication system or certification ECU (smart key ECU assembly) is malfunctioning, Data List items may not be normal.
- 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 the vehicle type under manual mode and enter the following menus: Body Electrical / Smart Key. 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.
HINT:
Using the GTS 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) Read the Data List according to the display on the GTS.

HINT:
- *1: This indicates that there is a problem with the communication format between the electrical key transmitter sub-assembly and certification ECU (smart key ECU assembly). Wave interference, malfunction of the electrical key transmitter sub-assembly or certification ECU (smart key ECU assembly), an electrical key transmitter sub-assembly from different vehicle being used, etc. are possible causes.
- *2: Engine start is permitted when it is confirmed that the steering is unlocked and the steering lock function is not malfunctioning. If engine start is not permitted, a steering lock ECU (steering lock actuator or upper bracket assembly) malfunction (relay, driver, etc.), an IGE circuit malfunction (wire harness or connector, ID code box (immobiliser code ECU), or a steering lock sensor malfunction are possible causes.
- *3: This indicates that transmission of the wake-up signal is possible ("Yes" indicates that the signal to begin verification-related LIN communication is being sent). When the steering lock motor is operating and an IGE ON signal is received (there is a steering lock operation request), or when communication is being performed between the certification ECU (smart key ECU assembly) and ECM, the display changes to "Yes".
- *4: This indicates that the engine start permission request signal (EGST) output from the ECM is being received by the ID code box (immobiliser code ECU).
- *5: This indicates the certification result of the certification codes of the certification ECU (smart key ECU assembly) and ID code box (immobiliser code ECU).
-
*6: This indicates the certification result of the certification codes of the ID code box (immobiliser code ECU) and steering lock ECU (steering lock actuator or upper bracket assembly).
When the steering lock ECU (steering lock actuator or upper bracket assembly) receives an unlock request from the certification ECU (smart key ECU assembly), confirmation of the ID code box (immobiliser code ECU) L code is performed. If the L code matches, the steering lock ECU (steering lock actuator or upper bracket assembly) unlocks the steering. Also, if the S code verification result does not match, the steering lock will not be unlocked.
- *7: The certification ECU (smart key ECU assembly) outputs a steering unlock request for 10 seconds after the ignition switch is turned ACC or ON, or an engine start operation is performed.
- *8: The certification ECU (smart key ECU assembly) outputs a steering lock request for 10 seconds after the ignition switch is turned off and any door is opened.
-
*9: Refer to the following Data List items when inspecting the actual vehicle.
-
HINT:
To check if the Data List display changes, get into the vehicle while carrying an electrical key transmitter sub-assembly and perform the following operations with the ignition switch off.
- *1: Press the engine switch with the clutch pedal released and check that the ignition switch turns ACC.
- *2: Press the engine switch with the clutch pedal released and check that the ignition switch turns ON.
- *3: Press the engine switch with the clutch pedal released and check that the engine starts.
- *4: Press the engine switch and check that the ignition switch turns off.
- *5: Open the driver side door and check that the steering locks.
-
Unlock operation conditions for the steering lock:
When the following condition is met, the unlock operation is performed.
-
The ignition switch is ACC or ON.
- When the ignition switch is turned ACC or ON and the key and certification ECU (smart key ECU assembly) are verified, the steering is unlocked.
-
When any of the following conditions are met, key verification is performed.
- The clutch pedal is depressed so that the engine can be started.
- 30 seconds have elapsed after opening and closing a door.
- The engine switch is pressed.
-
The ignition switch is ACC or ON.
-
Lock operation conditions for the steering:
When the following conditions are met and the certification ECU (smart key ECU assembly) has been verified, the lock operation is performed.
