C0615Park Brake Control Module Control Circuit/Open
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- 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.
