2004 Freightliner M2 Code Question?

[GearHd6]

Hello everyone, I'm new to these forums. My dad's truck is throwing a couple codes and he's wondering what they are and if he can fix them. It's got the C7 Cat engine.

One code is ECU 130
and the other is ABS 136

Does anyone have a clue of what those are?

Thanks for any info!
