DOOR LOCK  WIRELESS DOOR LOCK CONTROL SYSTEM(for NR Series Engine)  Only Wireless Control Function is Inoperative  


DESCRIPTION

When the wireless operation of the door lock function does not operate, a malfunction or wave interference may be occurring in either of the following: 1) the signal communication line between the electrical key and tire pressure monitoring system receiver assembly and certification ECU (smart key ECU assembly) (the line used for wireless operations): or 2) the electrical key transmitter sub-assembly. If the wireless lock operations cannot be performed, there may be electrical key transmitter sub-assembly malfunctions, wave interference or problems in the communication which is used for the wireless function between the electrical key and tire pressure monitoring system receiver assembly and certification ECU (smart key ECU assembly).

a.

Check the transmitter battery level of the electrical key transmitter sub-assembly.

i.

Press and hold the lock switch of the transmitter for 5 seconds and check the number of times that the transmitter LED illuminates.

HINT:

The electrical key transmitter sub-assembly sends voltage information to the certification ECU (smart key ECU assembly) when it is being used. The certification ECU (smart key ECU assembly) displays "Yes" for the "Key Low Battery" item of the Data List when this voltage information indicates 2.2 V or less.

HINT:
·

When the electrical key transmitter sub-assembly is brought near the electrical key and tire pressure monitoring system receiver assembly, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.

·

If the inspection result is that the problem only occurs in certain locations or 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.
