Well strange one. Owned my 24v since new, no matter how long it's been parked sometimes years with disconnected batteries. They key fobs have always worked and the truck started no problem.

 

Twice in the last 6 months my key fobs have stopped working and needed to be re coded to work and allow the truck to start! I didn't know this truck had any type of security immobiliser on it!

 

My ram is 99 with the sport package.

 

Does this sound like a CTM issue? If so are they plug and play? Or do they require coding?

 

Can I remove the factory immobiliser? 

 

Thanks for any help 🙏 

 

I'm in the UK so it's hard work getting parts over here.

I would start with the key fobs first check batteries and check to see if creating signal. CTM I've not heard of a failure really. Might check wires see if anything is damaged (mice).

Hi.mopar man 

Both batteries are new after the first incident. It's odd how both fobs de sync at the same time.

 

I've not seen much on CTMs dying.. I've also done some visual wiring checks all looks good. 

 

Think my clock spring has died also as my cruise doesn't work anymore 

Steering wheel radio controls? I'm wondering if the clock spring is making a voltage malfunction in the CTM. Short?

Sorry for the delay. No radio controls... Horn did fail around 10 years ago so could be a clock spring issue. Do you have any write ups on testing clock springs?

Thanks

Not off the top but should be ohm testing pin to pin per se between what the column has and the steering functions.
