4 documented codes across 16 real diagnostics.
Chassis-domain codes outside the standardised block, braking, steering, suspension or ride control depending on the make. Grouped rather than named because C1-C3 codes mean different things on different vehicles.
We have seen these in this area of the vehicle, and they get no page of their own on purpose. A manufacturer-specific code means different things on different marques, so a single description for one would be wrong more often than right. To decode one you need the marque as well as the code.
