retrofit OE PDC

Departed · 21st May 2007, 19:55

I bought my PDC and sensors a while ago from SMC, but only just got around to wiring up.

So far only on the bench, but had some odd results. So over to those with experience to suggest what it might be.

I've got power and ground wired up, but K bus is missing.

All sensors connected.

When I put 12v on the reverse light wire I get a double beep one low tone then one high. Then just a series of beeps as though it were working OK. However the beeps never change if you put anything near the sensors.

If I unplug one sensor, I still get the double beep, but two high ones. Then again contstant beeping.

Also, the system doesn't switch offwhen the reverse light wire goes low.

I guess it might be having no K bus, but does anyone recognise my rather poor descriptions of the beeps?

If not it'll have to wait until I get the thing on the car, and maybe testbook it.

Then I'll be back asking for measurements for fitting the sensors.
