Cant't make my cruise control working - what to try next?
Cheers everyone,
it is driving me a little bit crazy, my cruise control won't work as it should.
After switching the clock spring, I can switch it on and the dash will read "Cruise".
At about 25mph I can enable it and it works, but at about 40mph it will switch off itself - "Cruise" will disappear and it will not hold speed.
I changed:
Brake pedal switch
Rear differential speed sensor
Front left wheel bearing including wheel speed sensor
ABS light is off, so no obvious error(s)?
What else can I check and/or do to make it work?
I really need this for longer journeys to come.
Thank you!

Disclaimer: I am only a RAM enthusiast for all of 7 weeks now.
I don't think the cruise is getting a speed signal from the ABS sensors, rather on my other Chrysler vehicle (ahem, minivan) it is the output speed sensor on the transmission.
Now I know on my 545rfe transmission on my RAM1500, both the front and rear speed sensors are identical.
If it were me on my truck, I would try to swap the two sensors. Single bolt (10mm wrench). pull straight out. lubricate the o-rings with a little Vaseline
and they are magnetic so you'll likely find some small metal pieces (normal wear, FOD) so simply pinch/wipe away from tip with a cotton rag. In fact. it may even be a particle on sensor tip is tricking your computer from blinking out...
Now a cruise fault may not set a MIL, so you may have a non illuminated code. MAYBE an autoparts scanner can see it or may need a higher professional quality code scanner like SnapOn or Autel
Please tell me how this works out and what you find.. Also, how you eventually get it working (even if you take it to a shop, what do they find...) How much did it cost on August 2023 dollars...
It is your final debriefing, your feedback, that makes these forum threads complete. Nothing worse that reading a book and only to find there is no conclusion -OR- someone tore the last page out of a library book... Arg!!!

Now on my chryslerminivans.net forum, there was a guy in France that had limited access to Chrysler dealership but he had a need for DRBIII programming. That guy and his partner made his own, hacked his car computer, and then it was working pretty good so he offered it and lifetime upgrades for not much money.
I wonder if he now is WiTech?
YES, please let me (let us) know about your experience with this
Cheers!

FCW Not working
Hi Guys, I have a 2013 Dodge Durango Citadel 5.7 hemi engine with a dash warning up of FCW not working, took it in to shop to be told that I have to replace the front adaptive Cruise control module at $4800 CDN for part and then $400 for install.
I found a used one on E bay for $300 approx. supposedly all working, bought it and took it back to shop to install, they told me that there was already a VIN number in the unit that does not match my car so unit will not work, is this correct and is there a way to change the VIN number if this is so?

check your p/n
A lot of times when a VIN is set, like in the antitheft security module it can be permanent BUT a new module is a blank slate and when you install it the VIN is then set.
I can see this true with something like a security anti theft system but not maybe with cruise control, other that it would deter a theif from stealing a $1400 part from behind your bumper as it is more valuable than a used catalytic converter .
Please return and let us know what you find out or end up doing/paying in late August 2023 dollars.
