i tryed using freescan with no luck.. i bought one of andrews cables. IS there a step by step tutorial? im really looking to just pull codes right now. DO i just connect the cable and start the car or what?


thanks

 

Try this:

Open program
Select vehicle
select "force data" radio button
click "force data" button
select com port
click start

 

is this all when the car is off or on?

 

also what is the force data radio button? the interact option?

thanks

 

hmm it just scrolls "finding start header" continuously in the status window.

 

Oops, sorry. Yeah, interact.

Before you click start on Freescan, you must turn the key to ON and wait about 10 seconds. Thought you already knew that. I must have read this stuff somewhere.

 

It isn't that difficult, but there are several default selections you have to change to get it to work.

Select the proper COM port (Usually this is COM1).
Select "Interact" as the operational mode.
Select "GM 1994 Camaro..." or the appropriate vehicle under Vehicle Make and Comments.
Hit "Start" under "Communications with ECU".
If the Bytes Sent & Bytes Received counters don't start incrementing automatically, hit the force data button until they start to count.

You can do this with the car on or off, & the cable connected. Doesn't really matter. The key must be in the ON position though, running or not.

Selecting "Interact" gets a lot of people. If you don't set it to interact, it won't request any data from the PCM, even though the laptop and PCM are actually talking. Consequently FreeScan won't show you any data.

Usually "Force Data" isn't necessary. If you don't get communications immediately after following the steps above, hit the force data button a few times...this basically "kick starts" the communications. Once the "Bytes Sent" & "Bytes Received" counters start incrementing automatically, everything should be good. Click over to the data screen & you should see the data you want.

 

ok ive done it but i get nothign except a continuous stream of "finding start header" i clicked force data about 100 times. and nothing. ii did notice freescan is not getting my vin in the bottom right.. says vin= P .. also pccomm doesnt get my vin.and datamaster freezes. whats going on here? i bought the 95 dollar cable from andrew, but just to verify its correct. it has to pins on top right of connector and one on bottom right and 2 in the middle on to;.. my connector in the car just has 2 on top right 1 on bottom right and one on bottom left. is this ok?


what else can i do?

 

I also had some problems getting it to work at first. I finally re-downloaded and reinstalled the program. After that it decided to work correctly. You might give that a try.
