ABS light on and scanner question

[mikenj]

1st diesel.......bought truck with the ABS light on. Brakes work but want to fix before inspection. I have a scanner but when hooked up it didn't read anything. The truck is a 1995 f250......did a search and saw someone said its OBDII? Is that right? Does it need to be running to scan? Thanks!!

No ABS is not in with the OBII do you have a orange switch on your master? Are your brake lights working? That switch is under a recall to set the truck on fire! Don't let them just change the pigtail make them change the whole unit. If the Data Link connector is in the cab under the glove box then yes you have OBDII

Need to check on that orange switch but yes brake lites work for sure. If its orange does that mean it needs to be changed? Do I just call a Ford dealer and give them my vin #?

My scanner says OBDII is 96+ but yeah its under the passenger dash.

IDK about the OBS trucks, buy my '02 ABS light will come on when I kill the batteries or unplugh them.

95 trucks were a proto type. What the big three do is if they're gonna try something out they do it in trucks. Reason being is sales from trucks to cars is almost 6 to 1 meaning if they try something out in a car and it becomes an issue they have to issue a recall on 6 cars. Thats 6 items( whatever it would be) that Ford, GM, or Chrysler has to pay for vs 1 truck. Thats why the 95 trucks have OBDII. If you have the orange switch just drive to ford it takes them 20 min to swap it out.

What do you mean it'll come on? with the batteries unpluged??

Our trucks have the obdII plug but are obdII exempt so it will take a particular scanner to read any codes. but with that said abs codes do not show up on a scanner for our trucks. You will need to get the flash code by jumping the black wire with an orange tracer to a ground under the dash and counting the number of flashes. My truck is a 97 and it is the under the pass. side dash about in the center of the glove box. the black wire with the orange tracer is connected to a female solid red wire. If you have the red wire, turn on the ignition (engine still off), disconnect the red wire from the black with an orange tracer wire. Then connect a test lead to the blade at the end of the black/orange wire and then connect the other end of the test lead to something metal under the dash (a dash support works well). after connecting the test lead count the number of flashes of the abs light on the dash. it will be a series of short flashes with a long flash signaling the end of the code (11 short with 1 long equals codes 12). I attached a pic of what the codes mean. If you have any questions pm me. I have been fighting the abs light on my truck for the last 3 montths and I think I finally have it figured out so I would be happy to help you out.

OK, I see a orange thing in front of the master cyl......is that it?

T-ROD, thanks for help. I just went out and checked it. I counted 7 short flashes but it didn't do 1 long one? Code 7 is "no isolation solenoid during self check" and 8 is "no dump solenoid during self check" so its got to be one of those right? Any idea's?

Thats a tough one because I have never had the flash code without the long flash at the end but I would say you are definetaly on the right track. I would probably go with the 7 flash code first and then move to the 8 flash code it that doesn't fix it.

Any ideas what "solenoid during self check" could mean?
