Keeper Posted April 19, 2007 Share Posted April 19, 2007 Hi guys, When I start my R32 GTR the power steering is normal, once I get up to 70-80kph the power steering gets heavy as normal, but never loosens back up when it comes down to slower speeds or stopped again. After a little while longer the HICAS light comes on. I'm not overly fussed with the HICAS fault, the system is about to come out anyway, im concerned something isn't working right as when instrument fuse is blown (i think my power windows do it sometimes) the steering will stay light and not get heavy I saw this picture/diagram can someone describe in more detail what the vehicle speed sensor does, and if it is a replacable item or not. as I think this or the instrument its playing up (im hoping the speed sensor is the problem!)

heller44 Posted April 20, 2007 Share Posted April 20, 2007 (edited) The vehicle speed sensor is behind the speedo in your cluster, it is driven from the speedo cable going into the cluster itself. More than likely the system is going into fail safe mode after ~10mins and thats why it doesn't go light again. Have a search for heavy steering, it has been covered a few times lately, be better than repeating everything again. Also look for hicas diagnostics, it will tell you what bit isn't working right.

The hicas module controls the power steering. Fault in any of that system, and no power steering. Speed sender is built into the back of the speedo itself, If it is busted, or its wiring then yes it will show 0k in consult as that signal goes both to the ecu and hicas module.
