The Operation Range of the Power Source Switching Function has Decreased [11/2021 - ]: Procedure

1. Hold the digital key above the center console near the vehicle interior BLE digital key receiver and operate the power switch*1 or engine switch*2.
   NOTE:

   • Make sure there is no electronic device that outputs high-voltage or noise inside or around the vehicle.
   • Make sure that the digital key is not covered by or touching a metal object.
   1. *1: for HEV Model
   2. *2: for Gasoline Model
2. While moving the digital device closer to and farther away from the center console while repeatedly changing the power source mode, check the operating range.

   OK

   The range at which the power source mode can be changed is the same as the default.

   Vehicle Control History (RoB)

   Main Category	Sub Category	Memorized Conditions	Suspected Cause
   Digital Key (Inactive)	Operating Power Switch/ Digital Key Boundary Area	Digital key verification performed outside operating range	Digital key could not be detected within operating range Perform function inspection: Refer to OPERATION CHECK [11/2021 - ]
   	Operating Power Switch/ Digital Key No Motion	Verification was performed even though no digital key movement was detected	The vibration sensor of the digital key may be disabled or malfunctioning Perform troubleshooting for the digital key
   	Operating Power Switch/ Digital Key Response NG	Digital key verification has failed	A normal signal cannot be received from the digital key due to noise, etc. Refer to Precautions for Inspection or Registration and perform an inspection to check if the radio wave environment is the cause of problem: Refer to PRECAUTION [11/2021 - ]
   	Operating Power Switch/ Digital Key Invalid key	Verification was performed when the digital key was invalid	Digital key locked as it was detected that it was left inside the vehicle Check the message display of the digital key
   	Operating Power Switch/ Digital Key Out of Area	Digital key verification performed outside operating range	Due to some influence, digital key could not be detected Perform function inspection: Refer to OPERATION CHECK [11/2021 - ]
   	Operating Power Switch/ Digital Key Error	BLE digital key receiver communication malfunction occurred	Communication with the BLE digital key receiver was not possible Check for DTCs: Refer to DIAGNOSTIC TROUBLE CODE CHART [11/2021 - ] Perform function inspection: Refer to OPERATION CHECK [11/2021 - ]

2. Take appropriate action in accordance with the result of the cause analysis.
