Diagnosis System [09/2014 - ]

  1. DESCRIPTION 
    1. The steering lock ECU stores DTCs when a malfunction occurs in the system. These DTCs can be confirmed by using the Techstream.
      NOTE:
      • When using the Techstream with the power switch off to troubleshoot:

        Connect the Techstream to the DLC3 and turn a courtesy light switch on and off at 1.5 second intervals until communication between the Techstream and vehicle begins.

      • 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 is not connected to the CAN communication system. Therefore, communication with the Techstream 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.
