how it started. few months ago was driving down the road and the steering light came on.

every think was normal still had power steering.

on random occasions it started to die and go off then after around 2 weeks of this it went off

then only come back on on random occasions, I had I jacked up on passenger side 1 day and

then worked for a few days, I moved the pump by hand and I came on for a few days aswell.

randomly driving down the road it will come on, was parked at some lights on a hill pulled of and was working.

the power steering light has now started to flicker when hitting bumps in the road.

 

 

1.I have changed the battery, steering angle sensor

2.checked the wiring for resistance for the steering angle sensor

3.checked power to the pump

4.done the alternator load wire plug by the g gearbox, the battery light used to random stay on longer, flicker, not work, sum times, I have found this to be the plug on the alternator broke, the light now works properly but not 100% sure both wire are connecting properly on the plug

5. diagnostic check

code 01288 terminal 30 steering assist signal to low. ONLY SHOWS THIS WHEN ENGINE IS RUNNING

I have tried the fuses, added another earth.

code 01290 steering assist short to ground. I have changed the sensor code still shows and resistance checked on wiring

 

I am now thinking that it could be the load signal wire or the ecu in the pump has anyone got any ideas

 

 

Load signal wire would cause the battery light to flicker or not light up when the ignition is first switched on. Measure the voltage across the battery with the engine running, should be above 14V.

 

If it's the pump.

Look at the pictures and you'll see that the external data plug sockets connect with the internal PCB using sprung fingers contacting on the PCB, from the description of the symptoms it seems possible that one or more of these fingers is 'bouncing' and not making proper contact.

I've cheeked the battary voltage when running it reads 14.8v so guess the alternator is ok.

Was turning into my drive today full lock left and it came back light went off aswell, turned the steering to the right then it went off again. I went back to full lock left and it came back on, but soon as I straightened up it went off.

Still got the problem, on Boxing Day the dash warning lights started to come on randomly first the oil light flashing, restarted the car an went out, wouldn't Rev up, so restarted again now I have abs light on, from that day the pas light goes of when stationary, soon as you move its back on, also I plug diagnostics in and it comes up with no power to terminal 30, only when it's running it says this, the lights on the dash keep goin random on an off, could this be a earthing problem or corrosion on 1 of the fuse boards
