C0611Right Park Brake Actuator Control Circuit Low
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- 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.
