Code C0085 Saturn Description

The C0085 diagnostic trouble code (DTC) specifically indicates a malfunction in the Left Rear ABS Solenoid 2 Circuit of a Saturn vehicle. The ABS (Anti-lock Braking System) in a vehicle is responsible for preventing the wheels from locking up during braking, thus allowing the driver to maintain steering control. The ABS system relies on sensors, solenoids, and control modules to function properly. In this case, the code points towards a problem with the solenoid that controls the hydraulic pressure to the left rear wheel.
