STEERING LOCK SYSTEM DIAGNOSIS SYSTEM


  1. DESCRIPTION

    Note


    • When using the GTS with the vehicle 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.

    • Do not remove any fuses or disconnect the cable from the negative (-) battery terminal before confirming and recording DTCs as the data stored in the ECUs will be cleared.

    • DTCs may have been stored due to problems unrelated to the steering lock system. Be sure to confirm and record any DTCs output for other systems.


    1. The steering lock ECU stores DTCs when a malfunction occurs in the system. These DTCs can be confirmed by using the GTS.

    2. The steering lock ECU is not connected to the CAN communication system. Therefore, communication with the GTS is performed via the certification ECU (smart key ECU assembly).

    3. The steering lock ECU only stores DTCs for currently existing malfunctions. Past DTCs are not stored.
