C2200 on Ram

Anti-lock brake module internal fault (Ram, Dodge)

Severity: Inspect soon

FCA ties C2200 to the ABS light, which means anti-lock braking is not working; normal brakes still work but need service as soon as possible.

It gets more serious if:

Stop: Stop and have it checked immediately if the red brake warning light is on.
