C1073 Code

[Rob30]

I have been getting a C1073 code lately, the ABS and traction control lights are on. Cruise control is not working. I have checked the ABS fuses, all are good. I have power to the harness on the pump control. At this point how do I check the pump to see if it is working or seized? I don't have a wiring diagram. Is there a way to jump it to see if it turns on?
I did the back brake pads a couple months ago. The lights went out for a couple days. I am wondering if the valve body is full of crud and preventing the pump from working, causing the code. If that's the case, should I try opening it up and cleaning it out, or maybe just bleeding the system somehow? I want to exhaust all testing before pulling the pump and controller off and replacing. It does not look fun and pretty expensive to replace.

No input on this issue? A recent development is that the truck is starting up without any lights on the dash, but they come on as soon as I start moving now. Originally the lights were on all the time. I am wondering if anyone on here has any idea about how to test the abs pump and wiring. I would like to verify they are the problem before dropping $800 on a new pump and harness.

I can't help, but before dropping 800.00 I would let a mechanic diagnose the issue.

It seems like your going to need a scan tool that has the ABS functionality, such as ABS activation

The
Autel Maxicheck Pro EPB/ABS/SRS/SAS/BMS/DPF Auto Scanner OBD2 Trouble Code Reader will do it, it also has a function for DIY bleeding your brakes
They cost around $170
