Check light on
Hi. For the past year or so iv noticed when I'm pullin a load or driving for a long time the anti lock and the parking brake light will come on. It doesn't seem to be causing a problem just was wondering what it might be. It's a 90' f 350 4x4 5.8L

Thanks.

Best bet is to grab a scanner online for ~$20-25. Its so much easier then counting the lights and its almost fool proof. Get the digital version, otherwise you're still counting flashes.

That code reader will not read RABS codes.
None will that I know of.

Isn't the only part for RABS on a 1990 F350 the Sensor on the diff and the ring inside? That shouldn't be too hard to troubleshoot.

No there are other parts.
1. RABS Module
2. RABS valve
+ wiring from other sensor and switches.

Some also had rear brake proportioning valve with a arm to the rear end.

Do you know if this scanner will work on my 96 f250? I know the newer scanners for most 96 and on vehicles will not work on my 96 f250.

If it's OBDI and has the connector under the hood, then the EQUUS 3145 EQUUS INNOVA Ford OBD1 Code Reader Digital is what you need.
