DESCRIPTION
If the back door does not lock when using the power back door close and lock function, there may be communication problem between the certification ECU (smart key ECU assembly) and multiplex network door ECU.
CAUTION / NOTICE / HINT
Note
The entry and start system (for Entry Function) uses the LIN communication system and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the entry and start system (for Entry Function) after confirming that the communication systems are functioning properly.
When using the GTS with the engine switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start(CAN). While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.
After repair, confirm that no DTCs are output.
Check that there are no electrical key transmitter sub-assemblies in the vehicle.
Make sure that the electrical key transmitter sub-assembly is within the power back door close and lock function operating range when performing a back door close and lock operation.
