Diagnosis System [09/2014 - ]
- DESCRIPTION
- 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 engine 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 (-) 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.
- When using the Techstream with the engine switch off to troubleshoot:
- 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).
- The steering lock ECU only stores DTCs for currently existing malfunctions. Past DTCs are not stored.
- The steering lock ECU stores DTCs when a malfunction occurs in the system. These DTCs can be confirmed by using the Techstream.
