U0550Invalid Data Received From Side Obstacle Detection Control Module D
- Generic OBD-II code · Network
- How the car detects it
- Module D is the fourth radar of a side obstacle system, in Ford terms SODCMD alongside SODL, SODR and SODCMC. Which corner it serves depends on the vehicle and is not stated in the public Ford bulletins. U0550 has no published manufacturer description; a module receiving data from unit D sets it when that data proves invalid, for example a signal outside its range or a sequence error. Because these radars sit in bumper corners, impact damage, a bent bracket or water in the plug often come before network faults, and after a bumper repair the replacement module must be given the vehicle's configuration (Ford SSM 51903). The driver notices side assistance or cross traffic alerts disabled, not a drivability problem. U024F is total loss; module C is U054F.
