C060BLeft Park Brake Actuator Control Circuit/Open
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- On motor-on-caliper parking brakes, a small DC motor drives a gear stage and a spindle that pushes the rear piston; ZF quotes up to 19 kN clamping force with its early swash plate gearbox and up to 25 kN with a two-stage planetary set for heavy vehicles. C060B means the control unit (ESC module or separate EPB module) finds the drive circuit of the left motor open: broken lead, unplugged caliper connector or burnt winding. Hyundai uses its own code C2416 for an open or shorted left motor and fixed 2019–2022 Ioniq hybrids with new connector extension harnesses; GM's PIT5662A, filed under C056D/C056E, asks for no more than 6 Ω per rear circuit measured at the EBCM. No maker publishes C060B itself. The left caliper cannot clamp.
