Hello!

I'm currently dealing with an issue on my 1993 Ranger (4LV6)
The ABS light will turn on and stay on after reaching speeds above 10mph.
In addition, the rear brake lights wont turn on when the brake is depressd, the hazard lights/turn signals work and the brake light will turn on when the headlight switch is turn on.
Cruise control will also not turn on.
The brake fluid level is ok

Performing a KOEO test passes with code 111
The KOER test returns code 411 and 536
Code 411 - cant control low RPM during KOER test
Code 536 - Brake on/off BOO switch not activated during KOER test

When attempting to perform an RABS diagnostic test using the diagnostic connecter, the ABS light will stay off not flashing any codes

The RABS fuse is ok, I have replaced the rear ABS senor, brake light bulbs, and BOO switch and repeated the KOER test recieving the same fault codes

If anyone has any insight into this issue please let me know
Thank you!
