The dash indicator lights for my park brake on and ABS stay on all the time. The brakes work fine so I'm thinking it's a relay or sensor somewhere. I hate electrical computerized stuff. Any thoughts?

 

I have the same problem on my 1996 F-250 Power Stroke, I hope to see a good, cheap, simple answer. (Yeah right!)

 

On Ford and Dodge trucks, fault codes can be accessed manually by grounding the diagnostic pigtail connector on the ABS control module.
The flash code sequence for Ford, GM, Dodge and import trucks with the Kelsey-Hayes rear-wheel ABS system are the same, but the flash codes are slightly different. If you're reading flash codes, start counting from the first long flash. Then add the short flashes that follow. The total of the long flash plus any short flashes that follow equals the number of the code.
Because the system can only do one code at a time, the first code must be read out, diagnosed and repaired before the system can generate any additional codes.
RABS Fault codes
Codes for Ford RABS and GM RWAL applications are similar but have a few differences:
1. Should not occur (replace the controller if it does)
2. Open isolation valve circuit or defective ABS module
3. Open dump valve circuit or defective ABS module
4. Grounded or closed RABS or RWAL valve switch
5. Excessive actuations of dump valve during ABS braking
6. Erratic speed sensor signal
7. Shorted isolation valve or defective ABS module
8. Shorter dump valve or defective ABS module
9. High resistance or open speed sensor circuit (resistance should be 1000 to 2500 ohms)
10. Low speed sensor resistance (Dodge & Ford only)
11. Open speed sensor circuit (GM only)
12. Stop lamp switch circuit (Dodge & Ford)
13. ABS module speed processor (Dodge & Ford only)
14. ABS module program (Dodge & Ford only)
15. ABS module RAM memory failure (Dodge & Ford)
To manually clear a stored fault code on GM and some Dodge trucks with RWAL, remove the ABS fuse or disconnect the battery for 5 seconds. Ford RABS codes will automatically clear when the ignition is turned to the off position.
False codes
Kelsey-Hayes RWAL and RABS systems are vulnerable to a number of false codes. If terminal "H" on the ALDL connector is grounded when the warning light is not on, it will set a code 9. Nothing is really wrong with the system and the code can be cleared

that should give you something to do ...lol

 

wiring diagrams are here

 

Is that Mitchell software? Or what brand? I am getting the complete Mitchell set soon, yet have never seen it.

cheap and acurate

 

I know on mine, that those lights come on if I turn the key to far, it goes off after I turn the truck off and back on and nothing is wrong with either system.

 

If both lights are on, check the fluid level switch in the master cylinder. You're either low on fluid, have a faulty switch, or have a bad electrical connection.
