I've been having the hicas/speedo problem for a while now ...

 

ignition on, steering is fine, after a few minutes (time varies) of driving, the steering goes heavy and a short while later, the hicas light comes on. Lately, the speedo sometimes stays at 0, but this is not always the case and does not seem to correlate directly with the hicas prob.

 

I have run a conzult on it and noticed the following:

- steering angle was out by 240 degrees. Thought I had fixed this, but now its out again. Trouble is, conzult shows that it recognises the straight ahead position (the neutral indicator on conzult is enabled), but it reads 240 degrees right at that point. How can I reset this so that it reads 0 when the wheels are dead ahead and the sensor is in the neutral position!?! 240 is not a multiple of 360, so its not as simple as turning the sensor on the steering wheel round a number of times.

 

- the hicas and engine screens on the conzult are getting a 0 speed reading at all times. This is regardless of whether the hicas problem is occuring or the speedo is working. Thought it might be the speed sensor, but in that case, the speedo wouldn't be working (which it sometimes is).

 

If anyone has any suggestions, please let me know as its driving me round the bend!!

Import? If so it sounds like a badly fitted convertor for the speedo... Could also be a bad connection on the back of the clocks - the speed signal comes from the speed sensor to the clocks, then from there to other components...

Andy that does help mate, thanks!

 

Haven't checked the manual yet, but is it likely that the conzult port gets its signal further down the line than the speedo? I.e. the clocks are destroying the signal before it gets to the conzult so no reading.

 

There are 2 wires that have been cut (behind the clocks) for the convertor. One is yellow with a thin blue stripe, the other is yellow with a thin green stripe. Any idea which of those the speed convertor should be connected to? And should the other one simply be plugged back together (they both have crimp connectors on them) or left apart?

Yellow/blue is the feed from the speed sensor, this should have the convertor inserted in it (break the wire and solder the input of the convertor to the loom side, and the output of the convertor going to the cluster connector).

 

The Yellow green is the one causing your problems - if thats disconnected then NOTHING is getting a signal after the speedo, ECU, HICAS, PS control unit, cruise, Consult port......

thats brilliant mate thanks!

 

I'll have a look tonight. Since both wires were cut and had crimp connectors inserted when the car was originally converted, its possible that either there is a dodgy connection, or the converter is connected to the wrong wire.

Does anyone know how I can resolve the steering angle problem?

 

- attached consult and it was reading 240 degrees right when wheels and steering wheel where dead ahead.

- moved the wheel until conzult read 0 degrees and then switched of ignition.

- moved the wheel back to neutral position

- restarted ignition and conzult was still reading 0 degrees

- this seemed to last for a couple of days but is now reading 240 degrees or something again.

 

Am I right in thinking that the steering angle sensor is shafted?? Or is there a way to "teach" it what is neutral position?

 

Cheers

i had the same problem the speed convertor is the cause it has failed

simply plug the yellow crimp conectors together effectively removing the

speed convertor , this will unfortunately set your speedo to KPH and limit you to 110

but at least you will have your steering back until you get a new convertor ,
