No 4ws light. Not the usual issue

Animal Mother · Post by **Animal Mother** » Mon Oct 22, 2012 7:12 pm

I picked up the 5g lude last week. I already knew the 4ws light wasn't illuminating, so, as advised on here, I checked the fuse and the instrument cluster.

40A fuse? There and not blown.

Instrument bulb? There and working.

2WS instrument panel? No, definitely 4ws.

Any ideas anyone?

The light doesn't light up at all (on ignition etc).

Could the ECU have been disconnected?

These two comments seem to contradict one another.

Does the bulb illuminate at all?

Not really. The bulb is there and I've checked if it's working, it is.

When it's in the instrument cluster, it doesn't illuminate.

I even swapped it with the ABS bulb and the ABS warning light comes on.

I've ruled out broken bulbs, broken bulb holder, 40A fuse.

You need a multimeter & a wiring diagram.

I mean, you've checked the ECU is present?

I had a feeling that was coming.

Not yet. It's in the passenger foot well isn't it?

Definitely 4WS.

4WS ECU is in the boot, by the drivers side arch.
