   OK

   DTCs are not output.

NG → See step   15

B → See step   8 

A: Go to next step 

1. Move the electrical key transmitter sub-assembly as described below and perform the operation inspection. Refer to OPERATION CHECK .

   HINT: 

   • When the electrical key transmitter sub-assembly is brought near the front door outside handle assembly (for driver door) or electrical key antenna, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
   • The transmitted waves of the wireless function and entry function are the same, but the wave logic is different. As a result, it is possible that only the wireless function or only the entry function is affected by wave interference.
   1. Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the front door outside handle assembly (for driver door) and perform a driver door entry lock and unlock operation check.

      NOTE:

      Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.657 ft.) of the door handle.

   2. Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the front door outside handle assembly (for front passenger door) and perform a front passenger door entry lock and unlock operation check. (w/ Front Passenger Door Entry Function)

      NOTE:

      Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.657 ft.) of the door handle.

      HINT: 

      • If the inspection result is that the problem only occurs in certain locations or at certain times of day, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.
      • If wave interference seems to be the likely cause of the problem, ask the customer if the problem occurs in specific locations.
      • Move the vehicle to a different location, perform the following procedure and check if the symptoms can be reproduced.
      • If a tool for checking radio waves, such as a signal strength meter, is available, move around the area while observing both the LF band (used by the vehicle antenna to form the detection area) and RF band (used by the electrical key transmitter sub-assembly for transmission) to check for locations where there is wave interference.

      Result

      Result	Proceed to
      All operation checks fail	A
      All operation checks are normal	B
      Some operation checks are normal	C

B → AFFECTED BY WAVE INTERFERENCE 

C → See step   13 

A: Go to next step 

1. Check the following antennas in key diagnostic mode. Refer to OPERATION CHECK .
2. Select either channel 1 or channel 2 and inspect key diagnostic mode for each channel.

   HINT: 

   If the buzzer sounds with [CH1] displayed but not with [CH2], the electrical key transmitter sub-assembly cannot be detected by channel 2 due to a malfunction, such as wave interference.

   1. Check the electrical key antenna (for driver door):
