OK, I have the stalk, and the values change in PP2000 when the switches are activated, but whenever I try to set CC to 'present' in the 'instruments' section of PP2000 and it says something like 'update failed'.
After a bit more digging, I've found a document in Portuguese with the wiring of the 7.4.4 in the 206 and Citroen C3. The diagram has a brake and clutch switch input for the C3 only. These are wired to the 48 pin connector at positions M1 and F1 respectively.
The car has a 2 wire brake switch only, and no clutch switch. That said, PP2000 will occasionally throw a 'clutch switch' error in the ECU diagnostics. Go figure. There is a second hole next to the brake switch, and a hole above the clutch pedal.
I'm not sure if the braking signal is supposed to get to the ECU via a CANBUS message from the BSI, or directly via a switch. The brake switch wiring appears to go both directly to the brake lights in the BSI diagram, but there is also an extra wire (TR-NUM) that appears to go back to the brains of the ECU.
On the softcopy wiring diagrams, there is no clutch switch on the diagram with my RPO. If I select the 7.4.5 or 7.4.9 ECU, there is a clutch switch (7045) connected direct to the ECU, but no brake switch.
I'm thinking wiring any generic NC switch wired back to the ECU clutch terminal may well allow me to select the CC. (I am far too familiar with the ECU connectors - here's why...) I also have a set of spare ECU connectors and flyleads for the same reason. I'm still thinking the brake signal goes back via the ECU. Initially I'll probably just connect it to ground and see if it plays ball. Might even jack the front up so I can test the functionality in the driveway if I get that far.
I'm pretty sure the spare connectors I had were for an auto with cruise. On the spare 48 pin connector, there is no clutch wire to F1 (obviously) but there is also no brake wire to M1 which adds weight to my theory that the brake signal on the petrol cars comes back through the BSI.
Any thoughts?
Has anyone ever seen a CC fitted to a 206 Mux manual with a 7.4.4 ECU? If anyone knows of such a sample vehicle (factory or retrofit) I would appreciate you taking the time to PM me so I can ask you for some details of how it was done.
