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 [09/2014 - ] ). 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 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.
Check that there are no electrical key transmitter sub-assemblies in the vehicle.
Before performing the inspection, check that DTC B1242 (wireless door lock control) is not output (Refer to DTC CHECK / CLEAR [09/2014 - ] ).
Before replacing the certification ECU (smart key ECU assembly), refer to the smart access system with push-button start (for Entry Function) precaution (Refer to PRECAUTION [09/2014 - ] ).
After repair, confirm that no DTCs are output by performing the "DTC Output Confirmation Operation".
