AlumniCU Posted May 5 Share Posted May 5 2010 FFH is throwing Code: C0022 - Brake Booster Solenoid, Additional Fault Symptom (:14): - Circuit Short To Ground Or Open, in Forscan. Power brakes are out, Advancetrak is off, no regenerative braking. The hydraulic brakes work as expected. Have a new 12v battery, all fuses are good. My son drives the car, and noticed when the issue first happened the brake fluid reservoir was low. He added fluid and all was well for about a week. Reservoir hasn't dipped at all. Don't now if that is related or not to the C0022 fault. Code won't clear. Any ideas on how to approach? Replacing the brake booster looks like a PITA At 130K miles, this is my first real issue (other than resetting the battery date and replacing a wheel bearing). HELP! 0 Quote Link to comment Share on other sites More sharing options...
