After fitting a ECS Stage 2v2 brake kit complete with Hawk pads minus brake wear sensors I am now getting an error on startup - "CHECK BRAKE PADS!!", also a yellow circle with arcs around it.

I have the wires from the brake sensing terminal shorted together.

Should I have also done something else?

I have scanned the car with vagcom and found no errors.

You just need to change the first 2 number in the software coding for your instrument cluster (subtract 01)then the cluster will not be looking for any input from the wiring to the pads

Thanks for that!!

I was only looking at that the other day when I added the Navigation Menu!!

I have now coded out the pad wear sensor and added the seatbelt warning light.

Id still like to know why I got the warning when I had shorted the cables out though?

They may not be plugged in gary...

 

[GaryM]

I've pluged in a dummy connector with the cables shorted.

I checked the resistace of the sensor in my old pads and it was a dead short so shorting the cables should give the same effect as having good pads.

shorting the pad wear wires together does not turn the warning off as this is the condition to trigger low pad warning ie.when the pads wear the sensor touches the disc to make a circuit and put the light on.With the wires shorted together the car thinks the pads are worn out.You can either recode the module as you have or plug in some pad wear sensors and tie them up out of harms way.

I have a set of pad wear sensors - brand new and its a dead short across the cables.

 

[mgf255]

what happens if you plug these in instead of bridging the wires ?

 

[GaryM]

I'll try that but it shouldnt make a difference really.

 

[blazedoobie]

what were the results WITHOUT bridging the wires?

Didnt try that though open circuit should cause the error to come on if a new set of sensors are showing closed circuit.

seat belt warning ?

 

[EddyH]

Shorted together is definetely for worn out as the sensors work by the fact than when the pad is worn the circuit is completed by the disc surface as the 2 tails of the circuit are set at a certain depth within the pad material.

 

[GaryM]

They are not shorted to the chassis or negative though, only together which is from information read on Vortex.

A good set of pad sensors have less than 1ohm resistance between the cores which is a short circuit.

I assume that when either of the cores go to negative (disc) then thats when the pad sensor should come on.

seat belt warning ?

Nothing too flash, its only a light showing a man and a seatbelt across him for 5 seconds when the ignition is switched on.

Gary, I think the warning is triggered when the circuit is completed. I.E when the sensors touch the disc. By shorting the sensors you have in effect done the same thing, I.E made the circuit to trigger the warning.

 

[GaryM]

But a brand new sensor comes with a short circuit between both wires!!

 

[GaryM]

All now sorted.

I knew that the two cables had to be connected together so the only thing stopping this was the plug or socket.

Off came the wheel again to check, I then found that one of the pins in the socket had bent over and was not inserted into the plug properly!!

was that a vagcom thingy, setting type ?

Yes twas done with vagcom.
