C1412: Traction Control Valve LF Circuit Short To Ground
What does C1412 mean?
C1412 is a diagnostic trouble code indicating "Traction Control Valve LF Circuit Short To Ground". The ECU is detecting a voltage reading that is below the expected range in the stability control circuit. This typically points to a wiring short, a faulty sensor, or a grounding issue.
Symptoms you may notice
- Check engine light (MIL) illuminated on dashboard
- Intermittent warning lights
- Erratic gauge readings
Estimated repair cost
Typical range in Australia (parts + labour)
Common causes
- Damaged or corroded wiring harness
- Loose or disconnected electrical connector
- Failed stability control sensor or actuator
- Blown fuse in the related circuit
- Poor ground connection
What should you do?
This code sits in the stability and traction control system. Electronic stability control, traction control and the sensors feeding them may be offline, so the car will not correct a slide for you. It will feel completely normal right up until you need it, typically in the wet or in a sudden swerve. Get it diagnosed before driving in poor conditions.
