R32 Power Steering Issues

[gillies2001]

Hi there

Does anyone know what controls the variable power steering (ECU, speed, pressure) on the R32 GTST

My R32 only works on the heavy setting, it is power steering but doesnt change to the lite setting at slow speed.

It was working as it should when i first purchased the car.

Also i have change the steering rack solenoid and flushed and bled the system.

Any ideas please.

Does your speedo work?

[gillies2001]

Yes the speedo works fine and all dash lights go out when engine is started

Also the hicas had been removed before i purchased the car, and the steering was working ok then.

Have you done the basics and checked the fuses? Is the hicas ecu still plugged in?

It was working for ok for about 6 months and then started working only sometimes and now not a tall

It was working ok for about 6 months and then started working only sometimes and now not at all.

Also i have just replaced the flow solenoid on the steering rack = no change ?? Still heavy.

The speed sensor in the speedo (for the power steering) has also been replaced = still no change.

Any other ideas, Please.......

If you get the GTR manual on pdf, somewhere,cant remember where,

The steering diagnostic flow charts start on about page 580.

It looks like theres a few things it could be, but its sort of complicated, so read that, it should help.

I know its GTR but it would be similar if not the same. Anyway theres no HCR32 manual in english that i can find.
