Caution / Notice / Hint

NOTE:

The smart access system with push-button start (for Entry Function) uses a multiplex communication system (LIN communication system) and the CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting (Refer to HOW TO PROCEED WITH TROUBLESHOOTING [08/2015 - 08/2019] ). Troubleshoot the smart access system with push-button start (for Entry Function) after confirming that the communication systems are functioning properly.
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.
Check that there are no electrical key transmitters in the vehicle.
Before performing the inspection, check that DTC B1242 (wireless door lock control) is not output (Refer to DTC CHECK / CLEAR [08/2015 - 08/2019] ).
When checking the entry lock operation multiple times, the lock operation may be limited to 2 consecutive operations depending on the settings. In order to perform the entry lock operation 3 or more times, an unlock operation must be performed once (any type of unlock operation is sufficient). However, only consecutive entry lock operations are limited. Using the wireless lock or other types of lock operations, it is possible to perform consecutive lock operations without this limitation.
Before replacing the certification ECU, refer to the smart access system with push-button start (for Entry Function) (Refer to PRECAUTION [08/2015 - 08/2019] ).
After repair, confirm DTC not reoccur with performing the "DTC Output Confirmation Operation".
