Trying to figure out if there's something wrong with my cruise control or this is just how it works on the S2000. When I engage the CC for the first time, I feel it pull the pedal down and maintain the speed I want. If I cancel the setting or disengage the CC for any reason and re-engage it, the car slows down a few mph's and then accelerates to the speed I have set.

What's the deal here?

 

its normal since the throttle uses cable. If it was DBW you wouldnt feel anything since its electronic.

 

I understand that because there is a physical throttle cable, I will feel the pedal move when I engage the CC, but I can't understand why sometimes it engages immediately and other times it will allow the car to slow down and then accelerate it to the speed I've set.

 

There is a set-up procedure for the CC module. I had taken mine out for some work and when I reinstalled it I had issues where it couldn't maintain speed and do things similar to what you described. I looked it up in the shop manual, re did the cable to the module and it was all good after that.

 

would you like me post the actuator cable adjustment procedures for you, its a very simple adjustment

 

Yes please! That would be very helpful!

Silver, what cable did you have to re-do after installing your CC?

 

The one that conects to the CC module it. Our cars (2005 here also) are not DBW AP2s (YESSSS!!!!) so they use a throttle cable to also control speed when using CC. The adjustment of the cable (slack) controls how the CC is applied and how easily the module can control speed. I had mine to tight so it was very jerky and couldn't maintain speed well at all. Once I adjusted the amount of slack in to the cable correctly it works great.

I can get the directions later this evening if needed. Just got to pull out the shop manual...

 

Did you find the instructions on how to reset the CC?

 

Side tracked with a snow storm last night and have an appointment these evening, I could have it for you in the morning.

 

Great, thanks!

Sorry to hear about the snow storm, hope your S has tire chains!
