What it means
This code has no standardized generic meaning in the SAE/ISO list. Its meaning, if used by your vehicle, depends on the manufacturer.
How it works
C0615 is not assigned a standardized generic OBD-II meaning, so the title alone cannot confirm what the park brake control module circuit monitors or what condition sets the code. If the vehicle uses this code, its definition and diagnostic criteria depend on the manufacturer.
Common causes
Most likely first.
- Manufacturer-specific code definition
- Vehicle-specific diagnostic data needed
Symptoms
- Symptoms depend on the vehicle-specific fault
How to diagnose it
- Confirm the exact code and description with a scan tool that can read the vehicle's brake or parking brake module.
- Record which module reports C0615 and check manufacturer service information for the vehicle-specific definition.
- Review freeze-frame data and related brake-module codes before clearing the fault.
- If service information confirms an open control circuit, inspect the identified module connector and harness for disconnection, damage, or corrosion.
- Test the confirmed circuit for continuity and connection quality using the manufacturer's procedure and specifications.
Common fixes
- Obtain the vehicle-specific C0615 definition and diagnostic procedure.
- Reconnect a loose control-module connector if the vehicle-specific checks identify it.
- Repair an open wire or damaged terminal confirmed by circuit testing.
- Replace a module only if the manufacturer’s diagnostic procedure confirms an internal fault.
Can I keep driving?
Driving guidance depends on the vehicle-specific fault. If a brake warning is on or the parking brake does not apply or release normally, avoid driving until the fault is identified and the vehicle can be secured safely.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
