C062C code meaning
Brake Booster Motor B Performance
What C062C means
C062C judges whether the second drive, B, of an electric brake booster moves as commanded; the circuit may be intact. Boosters like Bosch's iBooster turn motor torque through a three-stage gear into force on the master cylinder, and in redundant layouts such as a Hyundai Mobis design a dual-winding motor is fed by two power modules, each able to carry the whole current command alone if the other is declared failed. No maker documents C062C publicly. The yardstick is its twin C0594 for motor A: GM's 2016 hybrid tables flag a motor below 15 rad/s while more than 25 rad/s is requested, more than seven direction changes, or reverse rotation above 40 rad/s, within 0.15 s, Type A. With side B out, assist may still come from side A only.

- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C062C
- Brake system or brake assist warning
- Harder pedal or reduced assist in some situations
- Driver assistance functions with automatic braking restricted
Common causes of C062C
- PossibleWorn or damaged motor B, for example bearing or winding damage
- PossibleFault in the power module or driver stage feeding side B
- Less likelyBinding in gear stage or booster mechanism
- Less likelyBooster control software needing an update
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of C062C means
| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 2C | The exact fault in that area. |
What to do next
- Note C062C 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 C062C
What does C062C mean?
C062C means "Brake Booster Motor B Performance". C062C judges whether the second drive, B, of an electric brake booster moves as commanded; the circuit may be intact. It is a generic code, so it means the same on every make.
Is it safe to drive with C062C?
Drive gently and only to a workshop. With C062C the car can go into limp mode (reduced power) to protect itself.
Will C062C fail an emissions test?
C062C 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 C062C to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will C062C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
