ABS light on, no others. Had C0201 on-and off, maybe 10% of the time for 6 months or so. Had ABS module repaired and problem persisted. Soldered a new substantial ground wire to the harness and grounded to frame. No difference. Started getting a C0110 code a couple months back, the ABS light is on most of the time. Van is a camper conversion, and I don't drive it unless we're on a road trip. JH6 brake configuration, VIN# 1GCHG39U341121868. Wiring harnesses appear to be in good shape. Thanks! Steve

If the wiring is good, you need a new ABS unit, including the module and valve/motor.

C0201 - ABS Pump Motor Circuit Malfunction
C0110 - Pump Motor Circuit

Here is the part you need to replace. Check out the images (below). Please let us know what happens.

If I remove the whole unit and replace the module with my rebuilt one, will I need to do the factory bleed? RPO says the system is JH6, what pumps can I replace it with? I've seen folks replace the unit with different parts.

Yes, you will need to open the ABS control valves while bleeding, here is a video to show you how:

I would stick to the ABS part numbers that match or are compatible. Please go over this guide and get back to us.
