You may not be aware of this, but walkie talkie, also known handheld transceiver, or two way mobile radio system can interfere with electronic systems on Toyota RAV4. Lets see which components are vulnerable.
Walkie talkies are popular in United States and are even used as toys, but its recommended to use them responsibly as they can affect electronic system in your vehicle. Toyota has revealed which systems can be affected by two way radio systems.
Multiport / sequential multiport fuel injection system (MFI): This system mainly improves engine fuel efficiency. With the enhanced cylinder-to-cylinder fuel dispersion of multi-point fuel injection, lesser amount of fuel is required for the identical power output. The normal operation of this system can be affected by use of two way radio systems.
Toyota Safety Sense 2.0: This system uses integrated camera and radar to prevent collisions due to delayed braking response by driver. Additionally, this system is also responsible for Dynamic Radar Cruise Control, Lane Departure Alert, Automatic High Beams, Road Sign Assist and Lane Tracing Assist. As you can see, this system is responsible for a number of vital safety features, so any interference could be destructive.
Anti-lock brake system (ABS): This is a safety anti-skid braking system which functions by preventing the wheels from locking up while braking in a vehicle, consequently sustaining traction on the road. Another important safety feature which two way radio systems can interrupt.
SRS airbag system: The function of the airbag is to offer passengers with soft cushioning to lessen the impact in a car crash. It can minimize or prevent injuries by stopping the passengers from crashing into the interior of the vehicle. One more safety system that radio waves can interfere with.
Seat belt pretensioner system: The purpose of pretensioner is to stop occupants in a vehicle from jerking forward in the event of crash. They are triggered by sensors in the car’s body and uses rapidly expanding gas to move a piston that pulls back the belt.
Given the systems that can be affected by use of two way radio systems, it is recommended not to use them while driving. But if using such systems is a requirement, then you should consult your Toyota dealer for methods of safeguarding these systems on your vehicle.
