What causes the trouble codes and warning lights?

Subaru has determined that the dielectric silicone grease in the plunger

area can actually reduce contact conductivity to the point where the brake light switch cannot provide a reliable ON/OFF signal. When that happens, the ABS, Hill Assist, Eye Sight and the Subaru Vehicle Dynamics Control systems don’t work properly.

Subaru has redesigned the brake light switch using a non-conductive fluorine grease instead. The new brake light switch is part # 83311FJ001 and is available from the Subaru dealer. The problem switch body has a grey color, while the replacement switch is blue with a green paint dot identification. The new switch has a retail price of around $16 but you can find it online for less by searching for part # 83311FJ001
