Is this level of detail from RAVE too? I've only ever used it for the wiring diagrams. EDIT: I've answered my own question. "Description and Operation" was the clue.

Yes, when the enabling signal is present.
Awaiting the result! Simon

There is virtually no voltage at C0895-9 under any conditions (virtually = +0.01v). The ECM signal is working in line with the P/R/N restriction as before at C0895-5. So apparently the interface/relay isn't outputting 12v when it should be.
Dougie.

OK, before condemning anything let's make sure that the interface ECU (aka cruise "relay") is getting all the supplies and data it needs.
Pin 1: earth Pin 2: not used Pin 3: not used Pin 4: variable voltage input from brake switch Hall sensor (C0075-4) Yes (post 56) Pin 5: cruise control enabling square wave signal from ECM (C0371-10) Yes Pin 6: 12v input from brake switch (C0075-3) Yes Pin 7: road speed square wave signal input from ABS ECU Pin 8: +12v ignition supply Yes Pin 9: switched +12v supply to cruise ECU (C0239-1) No Pin 10: road speed square wave signal output to cruise ECU (C0239-15) Pin 11: input from clutch switch Is this pin empty? Pin 12: +12v input from cruise master on/off switch. Yes Simon

Pin 1: earth Yes
Pin 2: (not used) Pin 3: (not used) Pin 4: variable voltage input from brake switch Hall sensor (C0075-4) Yes Pin 5: cruise control enabling square wave signal from ECM (C0371-10) Yes Pin 6: 12v input from brake switch (C0075-3) Yes Pin 7: road speed square wave signal input from ABS ECU Yes, +12v, stationary check Pin 8: +12v ignition supply Yes Pin 9: switched +12v supply to cruise ECU (C0239-1) No Pin 10: road speed square wave signal output to cruise ECU (C0239-15) Yes, +11.3v when cruise switched on, 0v when off, stationary check Pin 11: input from clutch switch Pin and tail present, not connected Pin 12: +12v input from cruise master on/off switch. Yes All answers have been double-checked. Dougie.
