:ranting: CAN ANYBODY HELP ME ON CRUISE CONTROL DRAMAS! New to the site and still working it out. I got a vn calais with stock c/c that stoppped working the other day. Being almost a sparky I have a fair idea about electrics. I found the diagrams last night on here, which were a huge help! I've tested the brake switches, which are now by-passed. Got power to the module from the fuse, all wires from the switch block and the earth continuity is also fine. which only leaves the speed sensor input. Do you know if this works as a pulse or just a plain voltage after a set speed? Do you think it could be the instrumentation shitting its self?
