K100G ABS Module - Bosch 0 265 151 202

Hey all,

Have a 1995 K100G with a N14 Cummins. Been a process going through the truck and fixing all the little issues.
Latest one is the ABS system, changed the dash ABS bulb and its shining bright with a fault.
Tried to google the Bosch ABS part number to determine how to diagnose it, but no luck what so ever.

Anyone worked with the Bosch ABS ECU before? any idea how to get a fault code out so i can start to repair it all.
Any information greatly appreciated!

 

Just has three bulbs in a row, "Truck fault", "trailer fault" and "non abs trailer"
I found the ABS unit mounted between the chassis rails, replaced all the fuses and confirmed I have battery voltage and ignition switch voltage (when turned on)
May be I'll flip the lid open on the ECU itself and see if there is a fuse internally.
I thought no light at all indicated no power to ABS?

 

Good news! Under the lid of the abs unit it has a test/diagnose button! Hoorahh. spits out some flashing codes so now I'm of and running to fault find the system and get it all working.
So far discovered front left wheel sensor is out, s
