C055F-00
ABS / stability-control fault code, listed for 1 vehicle line from Jeep. What it means on each one, with sources, and when the module is the cause.
What C055F-00 means
ABS Hydraulic Unit Performance - FCA TSB 08-032-22 Rev. A (2021 JL 4xe 2.0L PHEV, sales code ECX); software flash corrects a stored fault, active fault follows normal diagnostics
On: 2018-2020 Jeep Wrangler (JL)
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.
