Need Help With Steering!

[Keeper]

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!)

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.

cool, can i find it if i pull the instruments out?

if this is busted will it not return the signal to the ECU? in which a consult cable should show 0km/h all the time?

i looked and looked for heavy steering but everything is hicas related

... because it is hicas related.

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.

thanks, will wait till im rolling next week and check consult for speed signal, if i have one there god knows where i will go as i have swapped hicas ecus with a working one, so probably a dash?

anyway thanks and fingers crossed its just the sensor in the speedo
