WIRELESS DOOR LOCK CONTROL SYSTEM(w/o Entry and Start System) Only Wireless Control Function is Inoperative

DESCRIPTION

The door control receiver receives signals from the door control transmitter assembly and sends these signals to the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) then controls all doors by sending lock/unlock signals to each door, and sends hazard flasher signals to the combination meter assembly.

5. CHECK WAVE ENVIRONMENT

   
   

   1. Bring the door control transmitter assembly near the door control receiver, and perform a wireless operation check.

      Tech Tips

      
      

      • When the door control transmitter assembly is brought near the door control receiver, 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.

      Result
      Proceed to Wireless functions operate properly Wireless functions do not operate properly

   
   

   Wireless functions operate properly

   END (AFFECTED BY WAVE INTERFERENCE)
