C0112ABS Activation Frequency Too High
- Generic OBD-II code · Chassis
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- C0112 is not found in any accessible J2012 table or in the NHTSA bulletin index, and no manufacturer documents it publicly. Read literally, the title flags anti-lock control that starts again and again although the wheel situation does not justify it, as opposed to one overlong event (C0111). Nissan and Unisia patented a counter that sums pressure-release time across successive control cycles; when it keeps growing past roughly 0.5 s because one wheel speed sensor reads too high, that sensor is judged faulty and left out of the reference speed. The Bosch patent of 1988 switches ABS off when slip persists without braking. Plausible causes are a tyre of the wrong size, a cracked or loose sensor ring and electrical noise on a speed signal.
