Cruise Control Retro Fit issue : cruise control readiness = off

[bzguy]

Hi all, I just installed the cruise control retrofit on my C4S : cruise control set to "with cruise control" in DME (with Durametric Pro).

 

- I connected pin 1 cruise control to grey connector instrument cluster pin 17

- I connected pin 2 cruise control to fuse B7

- I connected pin 3 cruise control to grey connector instrument cluster pin 4

- I connected pin 4 cruise control to grey connector instrument cluster pin 1

 

However, when I read actual values, it says "cruise control readiness = off", whether I press the cruise control button or not.

 

No green light whatsoever.

Can anyone help ?

You may need a PST2 or PIWIS - on 2001 and newer cars I think you need to turn it on in both the DME and instrument cluster.

Loren is correct.  You need to code the instrument cluster for 'with cruise control'.

I thought Durametric Pro could enable this as well ? Or am I wrong ?

[Loren]

I have never done with Durametric Pro but their function matrix says it does.

Let us know how it works.

[bzguy]

It should indeed. It looks like it does, but still I can't send a cruise control command to light up the green light.

 

I send an email to Porsche dealer if I can hop in for a quick PIWIS activation, no answer yet ...

 

I'll keep you up to date.

I don't really understand what you mean by "I can't send a cruise control command to light up the green light". 

 

Can you read the instrument cluster input signals for the cruise control stalk?  How about the input signals for the brake and clutch switches in the DME?
