Struggling to figure this one out.

The car is a 97 BG GTB manual and it has the steering light illuminated on the dash but I dont know why?

I have checked the rack solenoid and thats ok

I have changed the speed sensitive steering control box but that didnt fix it

In fact even on another car when you unplug the steering control box it doesnt make the light come on?????

Does anyone have a wiring diagram for the steering system or know what controls the steering light on the dash?

Thanks for any help

Martin

Is fluid level alright, and does the steering, do what you want it to? (i.e. does the variable power assist work/you want it to work, or is the variable assist not working, and you don't want it to work) If so, pull bulb, done. I converted my rack to an Impreza rack on my GTB to get rid of the solenoid setup, predictably the steering computer hated that idea, so I pulled the bulb.


Not very helpful, I know, sorry. In short, good luck finding technical service documentation on JDM BG's, it seems non existant, so info on these JDM options will be forever illusive.

One can make assumptions on how the light will work. It can't be any more complex than ECU CEL's, so it can only be a few things setting the light off. There will either be a break in the wires, a short to ground, high resistance in the solenoid, or the p.s. pump sensor is borked. Test resistance on the wiring from solenoid to the controller, and from the pump sensor to the controller. If they all have reasonable resistance (less than an ohm or two), and no circuit is open, then the steering sensor migh be faulty, or the resistance in the solenoid too high. The solenoid ought to have high resistance inside of it regardless (a lots of ohms), since there will be a thin coiled copper strand, but the controller will likely have an upper limit with that resistance. Maybe look at a service manual for a turbo that you do have, go to the diagnostics section, and see what ohms to test for on the boost solenoid, it should be close enough to the steering solenoid.

That all sounds about as much fun as dining-in at macdonalds while a kids birthday is on... I'd just pull the bulb.

<Shale>: Blighter doesn't really have an accelerator pedal, it's more just a loudness pedal. You can change volume, but you won't go any faster.

<Reuben>: I feel like when you stomp the throttle in Blighter, it's like you've startled an old man!

Thanks for the reply Reuben

Due to the speedo converter that we have to fit in the uk to make the 180kph speedo work in mph the speed sensitive steering gets all messed up anyway

The GTB doesnt have a sensor in the pump unlike the pre 96 gt cars

On my own GTB if I disconnect the rack or the control box the dash light will still switch off as normal. So they cant be connected to the check circuit.

I will try another set of instruments to see if that helps and if not the bulb will be coming out :D

Try disconnect the KM-MPH box and see if it comes right.
Seems to me that there is a lot of issues in the UK that come back to these converter boxes, I am on an Estima forum and they have a heap of issues that come back to these

Is the steering computer the one that's bolted up under the column?

I thought the UK was metric anyway... it's always baffled me that they still use MPH on their signs.

Why not get a USDM speedo that has both K's and MPH readout?

I could fit a UK one that reads to 140mph but I am not sure if that would output the correct signals to the steering computer

Don't forget the ECU also, it gets its speed signal from the cluster. Don't know why they need to know speed, but it does affect the car... I'm guessing having the speed converted to MPH would not affect running at all though.

Won't effect the signals anything else receives just the scale of the meter sweep. Otherwise you'd see all sorts of issues with the aftermarket 240kph units and that simply doesn't happen.
