You dont need soft jaws.....just a rag will do.

Couldnt talk to the MID with Tech2, managed to talk to the radio though.

I think my Tech2 is knack'd  

My tractor had similar issue with MID, until I fixed all the faults it was complaining of. Wonder if poor error handling is knocking off diags?

I did have trouble talking to the radio at first, took some wiggling in the diag socket to get it to work.

Ah, phew, so poor connector then most likely.  It was too cold last night to spend too much time out there

Did you manage to talk to cruise or height control, as couldn't get these either. Need to check if all on same diag line.


Something not right with my Tech2. Next time I'm up, we may have to do a bit of part swapping to see if vehicle module thingie or the cable if thats OK?

Someone told me that if a car's been cheapo'd it can open up the contacts in the socket (due to the pins being too big) and this can cause bad connections with a "real" Tech 2.

It's even worse when people ram oversize paperclips in there

A minor rant here, so appologies in advance..............

Why can't someone design a Proper DC connector that will : give a good contact area, be self cleaning, be immune from damage thro cheap, Chinese connectors, have a proper strain relief, and last.

Laptop connectors are crap because the centre pin is smaller than the dia of the floating socket, so the area of contact is tiny, so crap for passing power. And its nearly impossible to solder a connector onto a PSU giving out 6A, the cable is to big to get into the housing. The old 1/4" is not bad, but suffers in that it needs a massive insertion force, and not suited to repeated use. The connector used for the OBD socket is prone to the contacts opening out, as above, and dear old GM provides the cigar lighter socket for powering auxiliary items. These are crap, they tend to break contact if you waggle them, and the plugs you buy are so cheap and crap that I don't like using them in case they fuse the car wiring.

Remember the old Radar/Military standard connectors, with individual gold flashed contacts, both the pin and socket were the correct dia, and wiped upon insertion. The housing was such that it locked into place, and could withstand a squaddie's standing on it without damage. OK, they cost about £50 each but.......

2) Main vac feed for the multirams and air injection was not connected to the brake servo pipe.

Gack, I've got a horrible feeling that may be my fault. I remember it falling off when routing new coolant pipes, I must have forgot to pop it back on

QED. There are plenty of connectors around that are very reliable (most automotive connectors perform very well considering the environment they're in) but consumer electronics can only afford to use cheap sh1t.

Yes, your prob right, I just haven't come across many decent ones !.  I had thought about fitting the car with a ring of decent power sockets for add-ons.

 Remember the old BNC, used for video signals. There were 2 types, 50R with a big fat pin, and 75R with a thinner tapered pin. If you plugged a 50R plug into a 75R socket, you splayed the socket so it was no use for 75R plugs again.

Having worked in a mixed video / RF environment that has caused a few moments of head scratching for me too.

BNC - a good way of separating video from audio.

Phono video are confusing, especially when mono sound kit is involved and the BNC kits audio is connected to video and mono

[Kevin Wood]

It's when you pick up a 50m ohm BNC patch lead instead of a 75 and use it for Video that it gets interesting. Where's all that ringing coming from?

Phono connectors are not great for audio IMHO let alone anything else but they're cheap.

no worries i should have spotted it!
