ABS Codes on OBD-II?
I got a code reader and I get no MIL codes when I scan the truck even though the ABS light is on all the time. I know I have seen ABS test sockets under the hood on Ford (post 96) vehicles... Is this not covered by the OBD-II and do I need something else to get ABS codes? Like one of those metal test keys that short out pins on the connector?
This is on a 2001 F-150.

ABS codes are NOT covered by OBD-II scans. I can all but guarantee it's your rear wheel sensor located on top of the differential. it takes about five minutes to R&R (one bolt). Part is about $12 through a retail parts store, and about twice that at the dealer. Replace it, and your light will go out, no codes to delete. Good luck.

That ABS light will stay on even after the part is replaced. You need an abs code reader to reset the ABS light on F150'S from 2000 and up as I understand the system. Ford told me that they would do it but I have to make an appointment and pay $59.95 for the service. My service shop just bought a system that will take care of the problem and they will reset it for free. autozone does not have an ABS-AIRBAG code reader.

I saw on TV sometime them using a metal key that shorts out a couple pins on the test connector to put it into blink mode where the ABS light will blink 3 times, pause, then 4 times for code 34 (for example) and go through that cycle a few times a few times at startup.
I don't remember what kind of vehicle it was. Does Ford have the same deal? I could just replace the diff sensor but I'd like to make sure its not a wheel speed sensor first.

On a system with just Rear Wheel ABS you don't need any tools to get codes. If it has 4WABS you need a scan tool.

I just did a repair on a 99 f-150 2 wheel drive with RABS. I just removed the front kick pnl. Look for a conector that has a red wire on one side, and a black wire with a orange tracer on the other. Unplug the connection. Now take a wire and ground the black/orange connector to ground for about 2 seconds. Your abs light should start to flash a two digit code.

In the time this thread has drawn on, the part could have been replaced 100X's over. ;-)

The easiest way to check if you have 4wabs or rabs is to see if you have wires going to the front wheels, in addition to the brake lines. If there are only brake lines, you have rabs only. Then you have to do the rutine mentioned above, grounding the wire in the right kick panel. If you see wires, you have front wheel speed sensors. 4wabs, you need a OBD2 scan tool to check the code. 95% of the time it is the rear wheel speed sensor on the top of the rear differential.
