Anyone got a working speed sender from a manual UK either for sale or to lend to me? Post to stoke on Trent Many thanks Dan

Ok, Well I have tried everything else, so got to be worth a go. Thanks

Ok to update, I have tried now a third set of clocks and a third ecu hicas unit and I am still getting heavy steering. Does anyone here know for sure if ECUTALK software using a consult lead would display speed. I get every other reading except for speed, and the funny thing is the doner car I tried various bits from also had no speed reading using ECUTALK. I am either thinking the car has the same fault or ECUTALK dosnt support the speed signal from the ecu? Many thanks

ok, i don't know if you can confirm for me, but the solenoid gets its signal from the hicas control unit, correct? That gets its signal from the ecu and that gets its signal from the clocks. I am down to this three items I guess. There's nothing else it could be? many thanks,

Sorry I didn't mean angle sensor I meant the solenoid on the rack. I get a steady 5.5 volts when the steering is light and a steady 1.5 when it is heavy. But something isn't telling it to adjust again as the speed changes.. Thanks Dan

Cheers, I'm in Stoke on trent, im going to have another look at it all this week. Another clue though maybe. Today the car did a journey start to finish about 3 miles in all. Stop start at the beginning and upto about 45mph and the power steering worked right through. The return journey was back to heavy steering after a few hundred yards... Thanks

I am using a consult plug to a USB into my laptop, I am using ecutalk software. Where abouts exactly do you live? Many thanks

Ok, I have now tried on my car a different set of clocks and a different hicas control unit. Neither fixed the issue. I tried my ecu talk on the doner car and that car had no speed reading either. So I can only assume now that my software dosnt read speed signals from 300zx ecu's. What comes after the ecu and hicas now? Sensor on the rack? Thanks

Thanks very much Mark for letting me try your parts this morning. I have established that it isn't my clocks or my hicas control unit... as I say anytime you need a favour returning don't hesitate to text me. See you Sunday mate..

Ok mate well tomorrow is good for me, can you text me your address on 07874247247. Is about 11am going to be ok?

I would be very grateful, when would be convenient for you?

Mark, do you have a set of UK clocks and a hicas control unit to try? Many thanks

It is drivable, yes...

Is anybody willing that is local to me help me fault find my code 14 error on my 1992 UK, I am now down to trying clocks and a hicas control unit. I'm in Stoke on Trent, staffs Many thanks Dan

Ok, got a mate here with me now, we have gone through everything again, jacked the back of the car up in the garage and looked for signals at both the ecu and hicas units and am getting fluctuating voltage as the wheels are spinning. I am still getting code 14. Only other thing is I recently swapped the ecu over and the fault has come about since then, the fault is still there however even if I swap back to my original ecu. Obviously I don't know why the fault would still be there even if the ecu's are swapped (no stored code). Do any other modules store codes? If an ecu is in kmph could that trigger a fault? Thanks

Cheers bud, going put a thread up see if anyone's closer to home and see how I go on, but might just take you up on that. Thanks for all your help. :) Dan

As I understand it the circuit starts at the gearbox sensor, to the clocks, onto the ecu and hicas then onto where? Steering rack? Is it possible that if there is a fault on the rack sensor then it will shut the system down? Or should I still get a speed signal from the ecu regardless? If it was your car where would you go from here? thanks,

I might just do that, lol. I guess I need to try a set of clocks and a speed sender. I have been for a drive and can confirm I can drive for quite some distance with no problem. Infact I believe I can drive with no issue at all as long as I don't slow down below 30ish mph. As soon as the car has gone above that speed it won't lighten the steering up after coming below that speed. Unless of course ignition off and back on..

From plug to plug it beeps. Cluster plug to plug pin 53 on ecu and cluster plug to plug pin 6 on hicas, both make a circuit ..

So from the clocks to pin 6 on the hicas unit?

Huh?, my ohms tester beeps when I test both ends of pin 53...

I have just checked for resistance and it's there, also the cable at both ends have no kinks or damage. Where do I go from here? As I understand it there is a signal coming from the gearbox as the speedometer works and there's resistance from the clocks to the ecu so the fault must be at the clocks?? Is there anything else I can check or test? Many thanks

Cheers, When I get home I will measuring resistance between pin 53 at the back of the ecu and the other end at the back of the clocks, if there is resistance then I guess the only place left to test is the signal out on the back of the clocks, how can I test this? Thanks

Cheers, not a clue, how would I tell?

Will get on that tomorrow and do a continuity test on pin 53 form the ecu to the back of the clocks and check for any damage to the sheath. I cant find a pin out diagram for the Hicas control unit though to show me which is the speed sensor pin and to where it goes to?? Will it be the same colour? Thanks,
