So I get the OBD Link EX get it all setup on Forscan and go to the truck to pull ABS codes and nothing. Doesn't even to be reading the ABS module.
That strikes me as rather odd that FORScan doesn't see an ABS node at all. If it's on the OBD2 bus, then FORScan should be able to see it.
For comparison, here's what FORScan shows for my 2004 Ranger:
Some thoughts....
Before starting FORScan, do you have the key fully turned (i.e. to the position where, if you turned it any further, the vehicle would actually start)? On my 2004 Ranger,
none of the nodes communicate unless the key is fully turned, but I know of some GM vehicles where
all of the nodes
except the ABS and airbag ("RCM" in Ford terms, "SRS" in GM terms) nodes will talk with the key only partially turned. (I really don't think that's the issue, but I'm trying to cover all bases.)
You might want to try running FORScan
after you've started the vehicle, just to be sure that all nodes are communicating. But
be careful what you do when the vehicle is running. Checking for codes is safe, but some other things may not be (e.g. clearing codes, resetting nodes, etc).
Do you possibly have an electrical issue (e.g. bad or intermittent fuse?) with the ABS? I'm not familiar with the 1999 Ranger but, again, I really would not expect FORScan to somehow fail to detect the ABS node, assuming it's on the OBD2 bus.
BTW, DTC (Diagnostic Trouble Code) "P1000" on the PCM node tells me that someone has recently done a reset of the emission-related DTCs. That's
not a big problem, but I would avoid doing that in the future unless it's necessary because it resets "freeze frame" and other important data and also invalidates all the "vehicle readiness monitors" too, forcing you to complete one or more "drive cycles" to prepare the vehicle for any possible state emissions inspection. If your problem is really ABS-related, then it's a
NON-emission thing and doing the typical "clear codes" thing that most tools offer is typically not recommended and may even just confuse the issue.
