C060B code meaning
Left Park Brake Actuator Control Circuit/Open
What C060B means
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.

- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C060B
- Red park brake lamp flashing or Service Parking Brake message
- Left rear brake does not apply when the switch is pulled
- Auto-hold or hill-start assist unavailable
Common causes of C060B
- Most likelyCorroded or loose connector or extension harness at the left caliper
- PossibleWire broken where the harness flexes with the suspension
- PossibleOpen winding in the left actuator motor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 0B | The exact fault in that area. |
What to do next
- Note C060B and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C060B
What does C060B mean?
C060B means "Left Park Brake Actuator Control Circuit/Open". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with C060B?
Drive gently and only to a workshop. With C060B the car can go into limp mode (reduced power) to protect itself.
Will C060B fail an emissions test?
C060B is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C060B to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will C060B clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
