MG MGF Technical - speciallists NOTICE regarding switch at steering column EPAS related (i.e. FAO Dirk Vael)

Hi all,

While trying to help Hanah on his intermitted upcoming SRS warning light I had a near look to the black box with security label under the steering wheel.
Have got it in my hands, but didn't open it currently.

It is a a 'sling ring' cable inside to provide connection of the horn switch and Driver airbag from the moving steering wheel to the chassis electric system.

Now it comes:

A very long 'cable' is winded inside. I would translate is as strip. Common also from printers i.e. the moving print head is connected to the main PC-board by such a multi-connection strip.

My advice is NOT to turn the centerplate with the yellow label useless and only for fun !!!

Why ?
I didn't open mine currently. But there is also a small switch on the right hand side. (at outer diameter).
Dunno what its good for, but have a theory regarding EPAS !!

Regarding the small switch at the outer diameter.

Looks like a cross >> + << with center bearing. Can turn like a wind mill.
A metal blade is at one end of this cross
On the opposit side of the assy (so left) is a blue shift blade. Obviously a transportation secure part.
I suppose this is required to prevent the center from useless turns before the box is mounted under the steering wheel.

Before disassembling the black box, pull this blue pin in your direction. Guess you need a small bended tool (2.5mm dia) and push it from rear to your direction. If the blue pin is out, then you can secure handle the box, cause useless turns are blocked.

This silly switch on the opposit of the blue pin works like a intermitted counter.
This switch is a tricky thing. A plastic cross with a metal blade.
On each turn of the center plate a small bolt gets to this switch and turns it once for 90 degrees.

I try to explain the sequence.
1. steering wheel in straight ahead direction = metal blade invisible.

2. turn the steering right = metal blade shows to the rear after 180 degrees steering wheel turn.

3. after another 360 degree it shows upwards

all inverted if you turn the steering wheel left.

2a. turn the steering left = metal blade shows to the front after 180 degrees steering wheel turn.

3. after another 360 degree it shows downwards

Can't someone else explain better or knows the reason for this 'counter'?
Is it for the EPAS ECU ???

Should or can I measure anithing to clear signals ?

Dirkiiieee urgent call !!!
Guees if this all is true then here can be another probabble fault for your EPAS problem.

Part Number of the box is YRC100170

wrong alarm.
Everything was crap. It isn't a switch. Its nothing but an indicator.
The blue thing is a 'break off' transportation security part

Thread closed ;-)
