C2100

ABS / stability-control fault code, listed for 6 vehicle lines from Chrysler, Dodge, Jeep. What it means on each one, from published sources, and when the module is the cause.

What C2100 means

Is it the ABS module?

Check the cheap things first: battery voltage and the main fuses for the ABS pump and module, the ground straps, the module connector (corrosion, a pushed-back pin) and, for wheel-speed codes, the sensor and its wiring at each wheel. If those are good and the code returns as soon as it is cleared — or the scan tool cannot talk to the ABS module at all — the module itself is the likely cause, and that is what we repair.
