U0114Lost Communication With Four-Wheel Drive Clutch Control Module
- Generic OBD-II code · Network
- Can trigger limp mode
- How the car detects it
- U0114 says the controller of a four-wheel-drive clutch has gone quiet. Such a unit sets how much torque reaches the secondary axle by clamping a multi-plate coupling, as in Haldex-type on-demand drivelines whose later generations carry their own integrated electronics. It needs wheel speeds, engine torque and brake status from the bus and is usually missed by the engine, transmission or ABS controller. Ford's 2014 powertrain code interpretation lists U0114, but no maker publishes timing or lamp logic for it. A transfer case controller has U0102, a complete all-wheel-drive module U011D, invalid clutch data U0414. In practice the car drives on one axle with an AWD warning; engine running and emissions stay unaffected.
