STEERING LOCK SYSTEM DIAGNOSIS SYSTEM


  1. DESCRIPTION


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

      Note


      • When using the intelligent tester with the engine switch off to confirm DTCs or Data List information related to the entry and start system, the intelligent tester 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 intelligent tester and vehicle begins, or 2) connect the intelligent tester to the vehicle and select "MANUAL" from the initial screen on the intelligent tester, and then select "KEY REGIST" under Model Code.

      • 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 actuator assembly (steering lock ECU) system. Be sure to confirm and record any DTCs output for other systems.

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

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