ABS fault codes — is it your module, or something cheaper?
Manufacturers reuse code numbers with different meanings, so each code here lists what it means on the vehicles that set it, with the page it came from. A code tells you where to look — not always that the module is bad. If the code keeps coming back after the basic checks, we repair the module from $499 — or send us the code and a label photo and we tell you first.
