C0615 code meaning
Park Brake Control Module Control Circuit/Open
What C0615 means
C0615 points at the circuit that feeds or enables the parking brake control electronics, not at a single caliper: it reads as open. Today the parking brake logic often runs as a software block inside the ESC unit (VDA recommendation 305-100), while the host supplies the motor power stage; a few cars keep a separate module. GM's EBCM tables for 2025 trucks show what such a check looks for, filed under C0616: if the motor supply line stays below 2 V for 500 ms during an apply or release, the clamp 30 feed counts as open. Mitsubishi sets C10B7-16 when the feed falls to 10 V or less. No maker publishes C0615 with this meaning; on 2014–2019 GM trucks C0615 is listed beside ride control codes in PIT5307G, which reflects an older GM assignment.

Symptoms of C0615
- Electric parking brake inoperative on both sides
- Parking brake warning lamp and service message
- Auto hold and hill start assist unavailable
Common causes of C0615
- Most likelyBlown fuse or fusible link in the parking brake power feed
- PossibleLoose or corroded terminal on the power or enable line at the module
- PossibleBroken wire between fuse box and module
- Less likelyInternal fault in the module's supply stage
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 15 | The exact fault in that area. |
What to do next
- Note C0615 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 C0615
What does C0615 mean?
C0615 means "Park Brake Control Module Control Circuit/Open". C0615 points at the circuit that feeds or enables the parking brake control electronics, not at a single caliper: it reads as open. It is a generic code, so it means the same on every make.
Is it safe to drive with C0615?
Drive gently and only to a workshop. With C0615 the car can go into limp mode (reduced power) to protect itself.
Will C0615 fail an emissions test?
C0615 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 C0615 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2 hours of work. This is a job for a workshop.
Will C0615 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
