So I go out to check for codes on my 91 but the scanner does not recognize it's plugged into the OBD1 port. The plug seems to be in tight so I'm a bit lost. Any suggestions as to what the issue may be, like the female connector ports are dirty. I'm old enough that my body can't contort to be able to get a good view under the dash unless I took the driver's seat out so I'm going by feel.

You might mention BRAND/MODEL of SCANNER to gather assistance!!

Oopps, sorry about that, it's an actron CP9690 Elite AutoScanner.

You could also get a Bluetooth adapter or USB cable so that you can do live scanning with your laptop or android phone using something like tunerpro.or aldscan.

But if the problem is with female OBD connector in car USB or Bluetooth still wont work.

Can you explain what you mean by the scanner does not recognize? Some scanners turn on when they sense a 12V power source. So how is your cigarette lighter working? If it isn't, check the fuse.

Did you try it without the cigarette lighter cable?

The scanner has menu accepts the inputs for selecting the year and model, but says it is not plugged into the port when I hit enter telling it to read. The scanner also is powered via battery so even if the lighter had no power the tool is still powered. I may have to try to remove the female port from its attachment under the dash so I can get a better look at the connections. Yesterday I was able to get the right side attachment point off, but the left side is still attached to some part of the dash. If the weather is reasonable this week end will have to try to get a cell phone picture so I can see what's going on under there.

When I did have it at the garage getting the oil sensor replaced about a month ago they said they dug out their OBD1 scanner out and was able to look for any issues while they had it. If anyone else is using the scanner I have hopefully they can tell If they have had any similar issues.

I tried both with and without.

But the cig lighter works and will power up stuff? Give Actron a call and see if the scanner is able to communicate

Will the scanner connect to your other vehicles. I realize they are probably OBDII, but you need to systematically remove all variables. I would in this order:

1. try to connect it to one of your other vehicles. I would NOT depend on a "it used to" but "ok I tried it and it did" so on to step 2.

2. now you have to find someone with a OBDI and test the unit that way, if so, on to step 3.

if not, maybe the OBDI cable is bad

3. put up a post and see if there is a fellow C4 owner close to you to see if it will connect. if it does, on to 4.

if it doesn't, you probably have a bad OBDI cable

4. start diagnosing the connection issue with your car

The scanner you are using Actron gave me the same problems on a 93. I bought an Innova ob1&2 and works fine

That is very interesting. As was suggested above I'm going to use it on one of my OBD2 cars just to see if it has any difficulties then.

If you just want codes, use the paper clip across pins 1 & 2 and count SES flashes.

I recently picked up a used AutoXray off e-bay, it immediately recognized my '88 Vette and recorded live tech data.
