Using the GTS, confirm the Data List items to help determine the cause of the problem.

NOTICE:

·

The steering lock ECU (steering lock actuator 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 engine switch off, connect the GTS to the vehicle 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 Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start(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.

HINT:

Unlock operation conditions for the steering lock:

When the following condition is met, the unlock operation is performed:

The engine switch is on (ACC) or on (IG).

·

When the engine switch is turned on (ACC) or on (IG) with the shift lever in P (for CVT), 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 brake 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.

Key verification occurs when the code emitted from the key and the code stored in the certification ECU (smart key ECU assembly) are compared to check that they match.

Certification ECU (smart key ECU assembly) verification occurs when the S code and L code are verified while the engine is being started or the engine switch is being pushed. The ID code box (immobiliser code ECU) uses the S code to determine whether the certification ECU (smart key ECU assembly) is authorized. The steering lock ECU (steering lock actuator assembly) uses the L code to determine whether the ID code box (immobiliser code ECU) is authorized.

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.

·

The engine switch is off.

·

The shift lever is in P (for CVT).

·

A door is opened or a door lock operation (door lock, wireless door lock or key-linked lock) is performed.

HINT:

·

The following example shows the behavior of various Data List items when the shift lever is in P, the brake pedal is not depressed, the vehicle is normal and the power source mode changes (for CVT).

·

The following example shows the behavior of various Data List items when clutch pedal is not depressed, the vehicle is normal and the power source mode changes (for Manual transaxle).
