U019E Lost Communication With Transmission Range Control Module

U019E covers the transmission range control module, in shift-by-wire designs the electronics that engage park, reverse, neutral or drive on behalf of the driver's selector. Ford lists U019E in its 2014 OBD code list without the MIL marker it gives emissions-related codes. No further public manufacturer source was found; NHTSA's bulletin index is silent on it as well. The neighbouring code U0103 belongs to the selector itself, gear shift control module A, which reports the driver's request to this unit. Shift-by-wire needs a redundant data path, so losing the range module typically means a refused gear change, a prompt to secure the car or an automatic move to park. U049F is invalid data, U01BA the park lock module.

Likely causes

Range control module without power, ground or wake-up
Bus connector at the transmission corroded or loose
Low battery voltage during cranking or parking
Transmission range control module faulty

Symptoms

  • Gear selection refused or vehicle stays in park
  • Shift system warning in the cluster
  • Transmission engages park on its own when stopping
