STEERING LOCK SYSTEM DIAGNOSIS SYSTEM


  1. DESCRIPTION


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

      Note


      • When using the GTS with the power switch off to confirm DTCs or Data List information related to the entry and start system, the GTS may not operate unless either of the following is performed: 1) Turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and vehicle begins, or 2) connect the GTS to the vehicle and select the Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start(CAN).

      • Do not remove any fuses or disconnect the cable from the negative (-) auxiliary 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.

    2. The steering lock ECU (steering lock actuator assembly) 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 (steering lock actuator assembly) only stores DTCs for currently existing malfunctions. History DTCs are not stored.
