C0611 code meaning
Right Park Brake Actuator Control Circuit Low
What C0611 means
C0611 means one of the two leads to the right parking brake motor is dragged toward ground. The harness to the right rear caliper rides on the suspension and passes close to the brake disc, so chafing against the knuckle or water in the plug are the usual suspects, followed by a shorted motor. H-bridge drivers such as TI's DRV8874-Q1 sense an output tied to ground as overcurrent and switch the bridge off, which leaves the motor without drive. Hyundai's bulletin for the Ioniq hybrids names C2417, short or open on the right motor, and fits an improved extension harness on that side. No maker publishes C0611. GM once listed C0611 in its connector test bulletin PIP5094 under an older, unrelated meaning.

What to do next
- Note C0611 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.
