Speedo, Heavy Steering And Front Drivers Headlight Issue?

[thirtyfourgtst]

Gday all, new to SCA and driving an R34 GTST,

Had a slight problem last night which I am hoping somebody can shed some light on.

Driving home from work yesterday and my speedo randomly went back to zero and the steering became heavier than usual. Went around a corner and all went back to normal. Got closer to home and it happened again. Had a look when I got home and it seems the drivers headlight had stopped working too. Left it a while and went for a drive that night and it seems corners and bumps are making it all turn on and off (speedo, power steer and 1 front headlight all at the exact same time). Also noticed the HICAS light come on at one stage but it went away the next time I started it. Just wondering what I should be looking for, for all 3 things to be working together? Where to start.....Im only new to skylines so im still abit rusty

Cheers Everybody!!

PS: The lights are HID's

slipping ps belt?

Doesn't hicas need a speed input otherwise the steering will go hard.

Speed input goes to dash first then off to ecu and hicas.

I'm sure they are related.

Headlight not related.

Thanks for the response guys! The power steering belt has a slight squeak to it but couldn't put that down to the speedo issue could we? I realise its a far reach to have the light issue related but why else would it all happen within the same split second everytime?

I'd check all your electrics, similar happened to be before, but my headunit would restart too.

Check/clean all your grounds and battery terminals, mine was grounding issue.
