Technical ECU Cant Connect

[MikeSalt]

I've just tried connecting to the engine without any adapters and it worked perfectly

Excellent! So the adapter, your ECU, MultiEcuscan and your laptop are talking nicely to each other. Looks like a faulty red adapter cable. Grab a multimeter and test the adapter against the wiring diagrams on MultiEcuscan. If the cable is rubbish, get one from London Electric.

Hi thanks for the reply and your help. I will try and get a multimeter and test it but I've been messaging the seller on ebay who I purchased the cable and adapters from.

Hopefully they will send a replacement or a refund.

Hi when I connect the red adapter the light still comes on on the main cable. Does this mean the adapters working? I'm just hoping it's a bad adapter and there's nothing serious wrong

What is the best next step would it be to try a replacement red adapter?

Is it possible that my airbag ecu doesn't work or not because I connected to the engine ecu?

Thanks

I have got a replacement red adapter being sent to me. Is there anything else that could be causing me this problem?

Pin 3 on your OBD port could be damaged perhaps?

How would I test to see if it was damaged?

Just a visual inspection is the best you can hope for at this stage. Alternatively, you'll need another similar Punto to test your equipment on, or a known, good red adapter that has been proven to work on another vehicle to test for damage to your vehicle's electrics.

try all the other adapters, ive got an early set of Gendan adapters and none of the colours match what mes says to use.

Ok thanks I have had a look at it and it all looks fine. The problem is I don't know anyone else with a Punto. The only thing I can think of doing now is waiting for the adapter to come and try it

Hi I will try this now. Thanks for the suggestion.

It says to check the adapter or com settings

hard to help what can we do realistically
did you do a pin through check with a buzzy multimeter?
i took one of my leads to bits once because i thought it had failed but it just wouldnt work on this particular car

do you not know anyone friends family with a punto you could try on to see if it works on theirs?

 

[dave]

have you checked the com port in device manager?

is the cars battery fully charged? had a mk2b once that although the battery would start the car mes wouldnt connect, fitted a new battery and it connected fine.

Hi the battery is fully charged I've just checked. What should the com port settings be ?
