- How the car detects it
- No manufacturer publishes C0850, and no code list carries it, so its use cannot be shown. The title refers to the electrically adjusted shock absorber at the left front. Its control unit sends a pulse width modulated current through a valve coil in the damper and measures the current that really flows; when the two differ, it stores a fault. GM does exactly this under its own number C0575 (Left Front Damper Actuator Circuit) on the 2011 Saab 9-5 and 9-4X, a meaning that differs from the J2012 use of C0575. The module then turns electronic damping off for that ignition cycle and shows SERVICE SUSPENSION SYSTEM. Stellantis uses C15C2 and C15C3 for the two left front valves (compression, rebound) on Ram 1500 and Charger from 2024.
