Power Door Locks/Keyless

Check for B-CAN DTCs. If any B-CAN DTCs are indicated, refer to the B-CAN system diagnosis troubleshooting (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A ) and resolve them first.
If the door lock system and the keyless operation do not work, troubleshoot the door locks first.
NOTE: The system does not function when the ignition switch is ON (II).
