Got autodata CD - How do a pinout check?

[timber1]

I want to do a pinout check.

But how do I connect to the ecu leads?

You know the connector in the footwell that garages plug their computer into to read the ecu? It looks kind of like a scart socket. Well the pinout data on the cd shows what each connector in their should read.

So can I buy a connector lead with flying leads to connect my multimeter to?

Do I have to make my own connector?

Can I pull the plug out and look for connectors on the back?

(The garage found no fault codes on the ecu, but Fords say a pinout check can show faults that the ecu readout doesn't)

its called a obd cable/reader,but depending on what car you own will need the correct software for it,

a lot of fords either have the connector sited under the ash tray or under the dash by your right knee.

Thanks.

But, I should have said that I am using a multimeter in conjunction with the data from Autodata.

In other words I just need to connect my multimeter to the right pins and read off the voltages.

There are 104 pins so I am guessing I need a socket which has 104 flying leads coming from it or I need to make a flying lead which will fit into / onto the pins?

Cheers,

What vehicle is it on? And what is the actual fault?

It may be more cost effective to get an OBD Code reader that enables you to do live readings via your laptop.

Back when I worked in a dealership we used to have pin out connectors specific to each ECU but with modern code readers these became obsolete.

Thanks for the replies guys.

Been going through the auto data cd (what a great source of info).

But now I am confused - can I do my own pinout check or not?

Ford Escort, 1.8Si 1998

In a nutshell there is hesitation upon acceleration.
It was really bad (dangerously so) but is a lot better since I did some work on the engine (head gasket, cam and aux belts, thermostat).

I don't know if the K-seal or the temperature sensor in the radiator top hose or the new cam belt, head gasket, thermostat etc has made the car better, but there is still this flat spot (50mph, 4th gear, go to accelerate, flat spot - change up to 5th, acceleration is fine (but not as rapid obviously) and no flat spot.

The ecu read out did flag up an engine temperature sensor (E.T.C.), but not as a proper fault code. I have renewed it (for one I had on the shelf which looked new - i.e. thread sealer intact and untouched - I will go back and test its electrical resistances to make sure it is ok).

Autodata states this problem could be E.T.C., MAF, Oxygen sensor, ignition.

Spent £200 on parts so far and still not fixed - this car will be new again soon at this rate.

Cheers,Tim

Hi mate

Have you checked out if you have the correct timing? i.e. the belt not skipped a tooth?

Check ignition timing also.

In case this helps anyone else:

the car is fixed - it was a £15 engine coolant sensor.

To do a pin out reading on this car you can access the back of the ecu plug and use an ordinary mutilmeter along with the data for the volages etc.
