C060B: Left Park Brake Actuator Control Circuit/Open

Open circuit on left electric park brake (EPB) actuator.

High severity. Can I keep driving?The regular brakes usually keep working, but without ABS or the driver aids. Drive very carefully and go to a repair shop; if the pedal feel changes, do not keep driving.

The ABS and stability control module monitors the wheel sensors, the pump, and the solenoid valves. If it detects a fault, it may turn off these driver aids.

Symptoms

ABS warning light on
ESC/stability control deactivated
Possible reduced brake assist
Speedometer may behave erratically

Most likely causes

Wiring break
Pin pushed back out of connector body
Cracked solder joint inside the module or sensor

What to check, in order

Start with the simplest. You can tick off each step.

Check that the brakes respond normally and check the fluid level
Check the continuity of the wire between the component and the control module.
Read the ABS codes with a multi-system scanner
Check the wheel sensors, connectors, and wiring
Compare the speeds of all four wheels in live data
Leave any work on the hydraulic circuit to a professional
