What's the c2200 code Dodge Charger?

On Dodge vehicles (including the Charger), code C2200 points to an issue with the anti-lock brake module (ABS). During normal operation, the ABS monitors internal microprocessors, ensuring that they're working properly. If they fail to do so, it will set code C2200. This code and issue is not considered critical; however, it can lead to loss of braking power, so it's recommended You address the issue at Your earliest convenience. Typically, code C2200 will necessitate replacement of the ABS module. Occasionally, there will be an intermittent failure, so You can first try to clear the codes, and then see if the error pops up again. However, it's likely that if it fails once, it'll fail again -- and maybe the second time, You'll be in a dangerous driving position. If I were You, I'd replace the module at once.
