3.0 DSC Light various error codes - Help!

[N3il123]

The other day I reversed off of my drive, went forward to go about my business and the DSC light came on after about 100 metres. Parked up, turned off, went to shop came back and the same, off for a bit then almost straight on.

I bought a new code reader and the cable for the under bonnet and it is reporting

A3 Transversal acceleration sensor
A4 Transversal acceleration signal
67 Brake light switch

I tried to clear them but they came straight back.

I then purchased a new brake light switch bouyed by the guide on pelican parts for replacement, except it looks like you can't remove the bracket as it is a manual and the clutch is in the way! So I connected up the new brake light switch (just dangling) with the old still in place (unconnected) and went for a drive.

Same error codes, so I am guessing that the brake switch is a red herring?

As an aside the boot of the car is getting wet caused by a ripped rear window, however the carpets don't appear wet to the touch.

Any ideas where to look next? without just splashing random parts at the car?

If you left the brake light switch hanging in mid air it would have left the brake lights permanently on. You could try doing it with the switch pin pushed in to turn the lights off (as it would be if mounted on the car) then see if the code goes away.

Hi

The trick to replacing the brake switch is to have a stick between the peddle and the seat motor to depress the brake peddle a little. This gives you room to pull the front collar on the brake switch forward to enable you to push the mounting tabs in. Have a look at your new switch to see the collar and how it locks the mounting tabs when the collar is pushed in.

The usual death of the Transversal acceleration sensor is water. The Air Bag side impact sensor suffer this fate too. Remove the drivers seat, part the carpet at the split and do a good inspection for water.

Thanks both , I thought of the brake switch being always open/ closed in the shower afterwards!

I'll give it another go tomorrow and report back!
