Did u know the dealer can reset your rear sensors to only be reactivated with a key cycle, not every time it goes into reverse ?

bring this to them and it's quick :

Special Service Message # 17815 - MULTIPLE VEHICLES -- PROCEDURE TO DISABLE REVERSE SENSING SYSTEM (RSS) FOR ENTIRE IGNITION CYCLE - SERVICE TIP.

Wow, if this is true it will make my very happy. There was talk of the July 04 flash as modifiying this behavior in an earlier thread, but it didn't seem to do it for me. I am going in for service in 2 weeks, I will definately persue this.
Thanks for the tip, and hope it works.

 

I'm confused, or actually ignorant.

What is the rear sensor and what does it do?

 

It is the sensors mounted on the rear bumper that warn you when you are getting close to something. It is an option, not part of any standard package.

When you are towing a trailer, everytime you go into reverse, the system detects your trailer and starts beeping at you. Very annoying when you are trying to backup to park.

 

Thank you for the education. I learned something new today.

 

why cant you just hit the off button????

 

I can disable my rear-sensor with the button they provide to turn it off. It's much easier.

 

Thats the whole point of the change, to make the "off" button stay set off until the ignition key is cycled again. When you are parking a large trailer, you often have to cycle between forward and backward several times to get the trailer positioned correctly. With the default button behavior, everytime to turn it off, it only stays off till you put the transmission into forward. Once you go back into reverse, the sensor turns back on. So every time you go from forward to reverse, you have to hit the off button. This is what is annoying. If you could turn it off ONCE, and have it stay off regardless of what you do with the transmission and direction of movement, then you can ignore it during parking. Once you turn off the engine, it resets to "normal" behavior, I.E. when you shift to reverse, it will be ON again. Make sense?

 

now it does..!!!!!

 

good post thanks for the info

 

jdad...


Great post! I will be having that done as soon as possible. Towing season is approaching!

Thanks,

JJ

 

I see this is for "MULTIPLE VEHICLES" does that include the 2003 Expedition?

 

Can anyone tell me that has had this done, if it's covered by warranty or did you have to pay for it to be done?

 

my 05 stays off until the ignition cycle.

 

I was thinking the exact same thing. Knowing my luck, they will charge me for it, as there is "nothing wrong" to repair under warrenty.
