The ABS light at IPC stayed on at first. Now it does not come on at all. Checked the connections.

What else can I check? Wheel speed sensors? ABS relays?

Can you help?
Thanks,
Armand

Sure, it is common for the ABS control module to go out on these carts, if the fuses and grounds are good here is how to replace the ABS module which should fix the problem, I would try to get used unit on ebay.

Here are the ABS and traction control wiring diagrams so you can check for power and ground to help confirm the component failure.
