C060C indicates that a drive line of the left parking brake motor is pulled toward ground. Typical reasons are a motor lead chafed against the body or axle, water standing in the caliper connector, or a shorted motor. The motor is reversed through an H-bridge, and protected bridge drivers such as TI's DRV8873-Q1 treat a grounded output as overcurrent and cut that half-bridge within microseconds. Both public cases on this hardware point at the wiring: Hyundai's 2023 bulletin for left-side motor short/open (its own code C2416) replaces the Ioniq connector extension, and GM's PIT5662A traces park brake messages to resistance in the rear circuits. No maker publishes C060C. The left motor is not driven, so secure the car in Park or in gear.

Likely causes

Motor lead chafed and shorted to the body or axle
Water and corrosion in the left caliper connector
Internally shorted actuator motor
