(T) Fiat Marea HLX Mk2 Cruise Control

thanks for the reply..
I don't fully understand what the 1234 membrane actually does..,

but the cruise icon on the LCD panel - I'd not consider looking there..,
I'll have to reconnect MES to my JTD..I was looking for a lit bulb

1234 is just the default membrane switch logos, they are: Stop, Start/set, - and +.
As for the cruise icon, that is all custom, the original odometer has been replaced by microcontroller+lcd that talks to the ECU and has cruise builtin.
Nothing on the original ECU.

My understanding was that all *facelift* models had no red key, my TD100 certainly had a red key.

Might need some of your experiences with my quest for cruise..

You mean me? Or someone with Lybra ECU cruise builtin?

Also here is picture of the stalk installed.

Not the greatest on hilly terrain as it only updates ~1.5 times a second because the communication to the ECU is not the fastest. Cruise might run 3x the speed if the speed/fuel consumption is disabled to reduce the message count.

Im still looking to retro.fit cruise to one of my older cars..

Garages are quoting @£500.. the value of the cars..


Found a 'kit' for @£180..

Might consider it.. then attempt to clone it for cheap onto a grande..

Somebody used a basic touchpad controlled system on a bravo-marea on here a few years ago.

I already retrofitted Cruise Control to my 2.0 CF3 marea. I used alfa 156 CC switch, which suit marea stalk - there are even holes for screws ! There were necessary to make additional connections from switch to ECU. Brake switch need to be changed to 2-contacts type from Lancia Lybra, or do a simple trick with ECU wiring. As cruise control lamp I used "injection fault" diode, because my version of car is already CF3 EOBD (check engine diode present), so it stay not used. The main problem was ECU - cruise control was internaly disabled by software, so when I connected CC switch, ecu recoginzed signals, but CC stay "not availabe" in diagnostic status. Fortunatelly I found all bytes (actually 2 + checksum), which are corresponding for CC. After that, all work fine. If someone is interested I can make a video about working CC.

4 years too late

better late than never

It would take more than a button..or lever to help my old JTD maintain 70mph
