C04xx

Chassis

Mechanical systems outside the powertrain: braking, ABS, traction and stability control, wheel speed sensing, steering and suspension. This dataset cannot narrow a chassis code further - the groupings behind the third character are not standardised across makes, and no free source covers them.

No open-source descriptions exist for this system, so its codes are read from their structure.

Standardised (SAE/ISO). Standardised meaning, consistent across manufacturers.
